The Benefits of Moderate Exercise for Body and Mind

The Benefits of Moderate Exercise for Body and Mind

“Can understanding moderate exercise and how to measure the amount of exercise help expedite individuals’ health goals and well-being?”

The Benefits of Moderate Exercise for Body and Mind

Moderate Exercise

Various physical activity guidelines recommend regular, moderate exercise for achieving and maintaining health and wellness. Getting the minimum, moderate weekly physical activity can help prevent disease, increase mental well-being, support weight loss and maintenance, and improve quality of life.

What Is It?

  • Anything that gets the heart pumping and beating faster is considered moderate exercise. (U.S. Department of Health and Human Services, 2018)
  • Moderate-intensity cardiovascular exercise includes – brisk walking, yard work, mopping, vacuuming, and playing various sports that require consistent movement.
  • When engaged in moderate exercise, individuals should breathe harder but still be able to carry a conversation. (American Heart Association, 2024)
  • The talk test is a way to monitor whether the exercise is at moderate intensity.

Benefits

Regular moderate exercise can help (American Heart Association, 2024)

  • Decrease the risk of developing conditions like heart disease, type 2 diabetes, and dementia.
  • Improve sleep and help with sleep disorders.
  • Improve brain functions like memory, focus, and processing.
  • With weight loss and/or maintenance.
  • Improve bone health.
  • Reduce depression, anxiety, and other mental health symptoms.

How Much Exercise?

The prescription for moderate exercise includes:

  • 30 minutes a day for five days a week, or two hours and 30 minutes per week. (U.S. Department of Health and Human Services, 2018)
  • Physical activity needs to continue for at least 10 minutes to be considered an exercise session.
  • Individuals can break up their 30 daily minutes into two to three shorter sessions, each 10 minutes long.
  • As the ability to exercise increases, aim to increase moderate activities.
  • Individuals will reap even more health benefits if they increase moderate aerobic exercise time to 300 minutes or five hours weekly. (U.S. Department of Health and Human Services, 2018)

Measuring Exercise

  • A moderate level of activity noticeably increases heart and breathing rate.
  • Individuals sweat but can still carry on a conversation.
  • Individuals can talk but can’t sing.
  • Individuals will feel the exercise but are not huffing and puffing.
  • Individuals can use different scales to measure exercise intensity.

Heart Rate

  • A moderate-intensity heart rate is 50% to 70% of an individual’s maximum heart rate. (Centers for Disease Control and Prevention, 2022)
  • An individual’s maximum heart rate varies by age.
  • A heart rate chart or calculator can determine an individual’s maximum heart rate.
  • To measure heart rate mid-exercise, individuals can take their pulse or use a heart rate monitor, app, fitness tracker, or smartwatch to ensure they stay at a moderate intensity.

MET

  • M.E.T. stands for Metabolic Equivalent for Task and refers to the amount of oxygen the body uses during physical activity.
  • Assigning METs to an activity allows individuals to compare the amount of exertion an activity takes.
  • This works for individuals with different weights.
  • During moderate physical activity, breathing and heart rate increase, and the body burns around 3.5 to 7 calories a minute.
  • The actual number burned depends on your weight and fitness level.
  • The body uses 1 MET for basic functions like breathing.
  • Grades of activity:
  • 1 MET – Body at rest
  • 2 METs – Light activity
  • 3-6 METs – Moderate activity
  • 7 or more METs – Vigorous activity

Perceived Exertion Scale

Individuals can also check their activity level using the Borg Rating of Perceived Exertion scale/RPE. (Centers for Disease Control and Prevention, 2022) Using this scale involves monitoring how an individual feels about how hard their body is working during physical activity. The scale starts at 6 and ends at 20. A perceived exertion between 11 and 14 is considered moderate physical activity.

  • 6 – No exertion – sitting still or sleeping
  • 7-8 – Extremely light exertion
  • 9-10 – Very light exertion
  • 11-12 – Light exertion
  • 13-14 – Somewhat hard exertion
  • 15-16 – Heavy exertion
  • 17-18 – Very heavy exertion
  • 20 – Maximum exertion

Examples

Many activities are counted as moderate-intensity exercise. Choose some appealing and learn to add them to a weekly routine.

  • Ballroom dancing
  • Line dancing
  • Gardening
  • House chores that get the heart pumping.
  • Softball
  • Baseball
  • Volleyball
  • Doubles tennis
  • Brisk walking
  • Light jogging
  • Walking or jogging on a treadmill
  • Using an elliptical trainer
  • Bicycling under 10 miles an hour on ground level
  • Leisurely swim
  • Water aerobics

Mobility Challenges

  • Individuals with mobility issues can achieve moderate intensity using a manual wheelchair or a handcycle and swimming or water aerobics.
  • Individuals who can use their legs but can’t tolerate walking or jogging can try bicycling or swimming.

Getting More Exercise

There are different ways to incorporate and increase moderate physical activities. These include:

10-minute Activity Bursts

  • Walk briskly for at least 10 minutes at a time.
  • Walk at an easy pace for a couple of minutes.
  • Pick up the pace for 10 minutes.
  • Try to walk during work breaks or lunch and/or before or after work.

Walking Workouts

  • Individuals can walk indoors, outdoors, or on a treadmill.
  • Proper posture and walking techniques make it easier to achieve a brisk pace.
  • Once comfortable walking briskly for 10 minutes, begin to extend walking time.
  • Try different walking workouts that offer fast walks, jogging intervals, and/or adding hills or treadmill inclines.

New Activities

  • Individuals are recommended to experiment with various exercises to find what works for them.
  • Consider roller skating, blading, or skateboarding to increase heart rate.

Moderate physical activity will get and keep the body in shape. Individuals should not become distressed if they can only do a little at first. Allow time to build endurance and gradually make time each day for enjoyable physical activities.

How to Train for Long Distance Walking Safely

How to Train for Long Distance Walking Safely

For individuals training for long distance walking marathons and/or events, can focusing on building a walking foundation, then increasing mileage progressively help condition the body for overall readiness?

How to Train for Long Distance Walking Safely

Long Distance Walking Training

  • Training helps individuals be comfortable and safe for long-distance walking and events.
  • Training should focus on building a walking pace and increasing mileage gradually.
  • Individuals need endurance, not speed, and want to build mental stamina for walking for hours at a steady pace.
  • To reduce the risk of training injuries, increasing the total mileage per week/the distance of the longest walk per week to no more than 10% is recommended.
  • Individuals should also train to wear the gear worn during long-distance walks.
  • Training could last a few months.
  • Being methodical allows the body time to repair and build new muscle, blood supplies, and endurance.

Example Training Plans

Following a marathon training plan for mileage building and determining the proper hydration, nutrition, and gear for multi-day walks and treks is recommended. However, individuals must build back-to-back long days into their training sessions to assess any issues or problems resulting from walking long distances on back-to-back days.

Example Walking Training Plans

Multi-Day Walks/Treks Training Schedule

  • 13 miles per day/21 kilometers
  • Use this plan for marathons or other multi-day walks with hills and natural surfaces requiring a backpack.

Training to Walk a Marathon

  • 26.2 miles/42 kilometers
  • This will condition the body to go longer distances.
  • When training for distances of 31 to 100 miles/50 to 161 kilometers, the longest distance to train should not need to exceed 20 to 25 miles,
  • These should be performed at least twice two months before the marathon or event.
  • Taper down the month before the event to a 12.4-mile/20-kilometer distance.

Gear

All clothing, shoes, sunscreen, backpacks, etc., must be tested on the longer training days before the event.

  • Given the climate and terrain, plan for what will be needed and removed.
  • Try things out, as individuals don’t want to be surprised with something unfamiliar at the event. From head to toe, test the gear, including:
  • Shoes/boots, socks, underwear, bra, shirt, pants, hat, jacket, and rain gear.
  • Choose shoes or walking boots and wear them on long training days to break them in and ensure they perform.
  • Backpacks should be tested on longer training days to ensure they can be carried comfortably over long distances and have the necessary capacity.
  • Choose wicking fabrics that allow the skin to breathe and cool, especially under layers. (Justin De Sousa et al., 2014)
  • Individuals will want to wear gear similar to marathon walkers if the walk will mostly be on pavement or asphalt.
  • Individuals can modify their gear if the route is off-road or during different seasons. Find out what other long-distance walkers have worn on the same route or event.
  1. Individuals can connect with fellow walkers via social media or find answers to frequently asked questions on the event’s or destination’s website.
  2. Individuals can also contact the event director via the website or social media.

Nutrition

Proper sports nutrition will prepare the body for endurance activity.

  • For example, individuals are recommended to follow a diet comprising 70% carbohydrates, 20% protein, and 10% fat.
  • Avoid high-protein diets, as they can cause hydration problems and strain your kidneys under endurance walking conditions. (Marta Cuenca-Sánchez et al., 2015)
  • Train with the water, sports drinks, food, and snacks taken to the event, and do not deviate from them during the event.
  • Water is needed for 20 kilometers and under events, but an electrolyte replacement sports drink may be better for longer walks.
  • Diluting or leaving out some sugar can be easier on the stomach.
  1. Have snacks pre-packaged and labeled for the times to be eaten.
  2. Individuals need to eat fat and protein for ultramarathon distances – this can come from trail mix, peanut butter sandwiches, and chocolate bars with nuts.
  3. Carbohydrates can be provided by sports gels or energy bars.

It is recommended to avoid products made for short distances and power sports as they can cause digestive problems when walking longer distances.

Planning a Walk

Planning begins by setting goals. Considerations include:

  • Time of year
  • Distance
  • Transportation to the event
  • Event pace requirements
  • Altitude and hill profile
  • Climate

Individuals are recommended to:

  • Prepare by researching routes and trails.
  • Study the course maps to know what services are provided along the way and what individuals must bring.
  • Walk a long distance without a supporting event.
  • Contact individuals who have walked the course.
  • Know the terrain and areas of total sun, hills, pavement, natural trails, and shade.
  • If possible, drive the course to become familiar with it.
  • Individuals may be able to find apps designed for their route.

Taking Breaks and Resting

  • Regular breaks should be short – using the bathroom, eating a snack, rehydrating, tying shoes, or bandaging blisters.
  • The body can stiffen up quickly during breaks and take several minutes to regain walking pace after a long break.
  • Recommendations could be taking a walking break instead, which means continuing to walk but at a very slow pace.

Foot Care

Individuals will have found what works for them concerning shoes, boots, socks, etc., on the long training days to prevent blisters and injuries. It is recommended to try different strategies, which include:

  • Sports tape
  • Blister block pads
  • Sprays
  • Lubricants
  • Wicking and/or double-layered socks
  • Moleskin
  • Stop at the first sign of irritation along the walk and doctor the foot with tape, blister bandages, or whatever method works best.

The body was built for walking. Planning and training properly before taking a long-distance or multi-day walk will ensure a safe and enjoyable marathon.

Acupuncture for Reducing Joint Pain in Lupus: A Natural Approach

Acupuncture for Reducing Joint Pain in Lupus: A Natural Approach

Can individuals dealing with joint pain incorporate acupuncture therapy to manage lupus symptoms and restore body mobility?

Introduction

The immune system is highly important to the body as its main job is to protect vital structures from foreign invaders that can cause pain-like issues and discomfort. The immune system has a healthy relationship with the different body systems, including the musculoskeletal system, as the inflammatory cytokines help heal muscle and tissue damage when the body is injured. Over time, however, when normal environmental and genetic factors start to develop in the body, the immune system will begin to send out these cytokines to healthy, normal cells. To that point, the body starts at risk of developing autoimmune diseases. Now, autoimmune diseases in the body can cause havoc over time when they are not managed, leading to chronic disorders that can cause overlapping symptoms in the musculoskeletal system. One of the most common autoimmune diseases is systemic lupus erythematosus or lupus, and it can cause a person to be in consistent pain and discomfort while correlating with muscle and joint pain. Today’s article looks at the factors and effects of lupus, the burden of joint pain in lupus, and how holistic approaches like acupuncture can help manage lupus while restoring body mobility. We talk with certified medical providers who consolidate our patients’ information to assess how to minimize the pain effects caused by lupus on the joints. We also inform and guide patients on how acupuncture can help manage lupus and combine other therapies to reduce its pain-like symptoms affecting the musculoskeletal system. We encourage our patients to ask their associated medical providers intricate and important questions about incorporating acupuncture therapy to relieve the inflammatory effects of lupus while finding natural ways to restore mobility. Dr. Jimenez, D.C., includes this information as an academic service. Disclaimer.

 

The Factors & Effects Of Lupus

Have you been experiencing joint pain in your upper or lower extremities, making it difficult to function throughout the day? Have you been feeling the constant effects of fatigue? Many individuals experiencing these pain-like issues could risk developing systemic lupus erythematosus. In this autoimmune disease, the body’s own immune system mistakenly starts to attack its tissues, thus leading to inflammation and a range of pain-like symptoms. Lupis is tricky to diagnose because of its complex immune dysregulation that can lead to an overproduction of cytokines that can affect the body. (Lazar & Kahlenberg, 2023) At the same time, lupus can affect a diverse population, with symptoms and severity varying depending on how mild or severe the factors affect the body. Lupus can impact various body parts, including the joints, skin, kidneys, blood cells, and other vital body parts and organs, as environmental and hormonal factors can influence its development. (Tsang & Bultink, 2021) Additionally, lupus can be closely associated with other comorbidities that are causing overlapping risk profiles with inflammation that can affect the joints in the musculoskeletal system.

 

The Burden of Joint Pain In Lupus

 

Lupus is tricky to diagnose since it often mimics other ailments; the most common pain symptom that lupus affects is the joints. Individuals with lupus experience joint pain, which can cause inflammatory effects and structural damage to the joints, tendons, muscles, and bones, causing pathological abnormalities. (Di Matteo et al., 2021) Since lupus causes inflammatory effects in the joints, many individuals will think that they are experiencing inflammatory arthritis, and it can cause overlapping risk profiles as it is accompanied by lupus, thus causing localized pain in the joints regardless of its origin. (Senthelal et al., 2024) Joint pain in lupus individuals can significantly hinder daily activities, reducing mobility and overall quality of life as they are trying to find relief. 

 


Unlocking The Secrets of Inflammation-Video


 

A Holistic Approach to Managing Lupus

While standard treatments for lupus involve medication and immunosuppressants to reduce the inflammation caused by lupus, many people want to seek out holistic approaches to manage lupus and reduce the inflammatory effects from affecting their joints by making small changes in their lives. Many people incorporate anti-inflammatory foods rich in antioxidants to dampen the inflammatory effects. Various supplements, like vitamin D, calcium, zinc, etc., can help reduce inflammation caused by lupus and strengthen bone health. Additionally, non-surgical treatments can even improve cardiorespiratory capacity and decrease fatigue while improving psychological function, which can help improve a person’s quality of life by managing the symptoms caused by lupus. (Fangtham et al., 2019)

 

How Acupuncture Could Help Lupus & Restore Mobility

One of the oldest forms of non-surgical and holistic approaches to reducing inflammation and managing lupus is acupuncture. Acupuncture involves solid, thin needles used by highly trained professionals to be inserted into specific body points to balance the body’s qi (energy) by stimulating the nervous system and releasing beneficial chemicals into the affected muscles, spinal cord, and brain. Additionally, acupuncture, with its minimal side effects and holistic approach, can help manage lupus. This is because when acupuncture needles are placed at the acupoints of the body, it can disrupt the pain signals that are causing pain in the affected area and regulate the inflammatory cytokines from lupus to provide relief. (Wang et al., 2023) This is due to its philosophy of addressing not only the physical pain but also the emotional and psychological symptoms of living with a chronic condition like lupus.

 

 

Additionally, acupuncture can help restore joint mobility while managing lupus through consecutive treatments, as many people notice that their joint mobility is improved and their pain is diminished. This is because the insertion and manipulation of the needles in the body’s acupoints cause alterations in afferent sensory input to the central nervous system, which increases alpha motoneuron excitability and reduces inflammation. (Kim et al., 2020) When individuals are dealing with lupus and are trying to find alternative holistic methods to relieve inflammation and joint pain caused by lupus, acupuncture, and non-surgical treatments can offer a ray of hope in managing the daily challenges of lupus.

Structural Mechanics and Movement: Biomechanics Explained

Structural Mechanics and Movement: Biomechanics Explained

For individuals experiencing musculoskeletal issues and pain symptoms, can learning about biomechanics and how it applies to movement, physical training, and performance, help in injury treatment and prevention?

Structural Mechanics and Movement: Biomechanics Explained

Biomechanics

Biomechanics studies all life forms and their mechanical workings.  Many think of biomechanics in sports and athletic performance, but biomechanics helps create and improve technologies, equipment, and injury rehabilitation techniques. (Tung-Wu Lu, Chu-Fen Chang 2012) Scientists, sports medicine doctors, physiotherapists, chiropractors, and conditioning specialists utilize biomechanics to help develop training protocols and techniques to improve therapy outcomes.

Body Movement

Biomechanics studies the movement of the body, including how muscles, bones, tendons, and ligaments work together, especially when movement is not optimal or correct. It is part of the larger field of kinesiology, specifically focusing on motion mechanics and analysis of how all the individual parts of the body work together to make up athletic and normal movements. (José M Vilar et al., 2013) Biomechanics includes:

  • Structure of bones and muscles.
  • Movement ability.
  • Mechanics of blood circulation, renal function, and other functions.
  • The study of forces and the effects of these forces on the tissues, fluid, or materials used for diagnosis, treatment, or research. (Jose I. Priego-Quesada 2021)

Sports

Sports biomechanics studies motion in exercising, training, and sports, which incorporates physics and the laws of mechanics. For example, the biomechanics of a specific exercise looks at:

  • Body position.
  • Movement of the feet, hips, knees, back, shoulders, and arms.

Knowing the correct movement patterns helps make the most of the exercise while preventing injuries, correcting form mistakes, informing training protocols, and increasing positive results. Understanding how the body moves and why it moves the way it does helps medical professionals prevent and treat injuries, alleviate pain symptoms, and improve performance.

Equipment

Biomechanics is used in the development of physical and sports equipment to improve performance. For example, a shoe can be designed for optimal performance for a skateboarder, long-distance runner, or soccer player. Playing surfaces are also studied for this purpose, such as how the surface stiffness of artificial turf affects athletic performance. (Jose I. Priego-Quesada 2021)

Individuals

  • Biomechanics can analyze an individual’s movements for more effective movement during training and games.
  • For example, an individual’s running gait or swing can be filmed with recommendations on what to change to improve.

Injuries

  • The science studies the causes, treatment, and prevention of neuromusculoskeletal injuries.
  • The research can analyze the forces that cause injuries and provide information for medical professionals on how to reduce the risk of injury.

Training

  • Biomechanics studies sports techniques and training systems to develop ways to improve efficiency.
  • This can include research on positioning, release, follow-through, etc.
  • It can analyze and help design new training techniques based on the mechanical demands of the sport, aimed at resulting in better performance.
  • For example, muscle activation is measured in cycling using electromyography and kinematics, which helps researchers analyze factors like posture, components, or exercise intensity that affect activation. (Jose I. Priego-Quesada 2021)

Motions

In biomechanics, the body’s motions are referred to from anatomical positioning:

  • Standing upright, with the gaze straight ahead
  • Arms at the sides
  • Palms facing forward
  • Feet spaced slightly apart, toes forward.

The three anatomical planes include:

  • Sagittal – median – Dividing the body into right and left halves is the sagittal/median plane. Flexion and extension occur in the sagittal plane.
  • Frontal – The frontal plane divides the body into front and back sides but also includes abduction, or moving a limb away from the center, and adduction, or moving a limb towards the center in the frontal plane.
  • Transverse – horizontal. – The upper and lower parts of the body are divided by the transverse/horizontal plane. Rotating movements occur here. (American Council on Exercise 2017)
  • Moving the body in all three planes occurs with daily activity. This is why performing exercises in each plane of motion to build strength, function, and stability is recommended.

Tools

Various tools are used to study biomechanics. Studies are usually performed using a device known as electromyography or EMG sensors. Sensors are placed on the skin and measure the amount and degree of muscle fiber activation in certain muscles during test exercises. EMGs can help:

  • Researchers understand which exercises are more effective than others.
  • Therapists know whether patients’ muscles are properly operating and functioning.
  1. Dynamometers are another tool that helps measure muscle strength.
  2. They measure the force output generated during muscle contractions to see if the muscles are sufficiently strong.
  3. They are used to measure grip strength, which can be an indicator of overall strength, health, and longevity. (Li Huang et al., 2022)

A Guide to Motor Units: Benefits of Weight Training

A Guide to Motor Units: Benefits of Weight Training

For individuals starting to lift weights, motor units are important for muscle movement. Can building more motor units help build strength and maintain muscle mass?

A Guide to Motor Units: Benefits of Weight Training

Motor Units

Motor units control the skeletal muscles and are the force behind every body movement. (C J. Heckman, Roger M. Enoka 2012)
This includes voluntary movements like lifting weights and involuntary movements like breathing. When lifting objects and weights, the body adapts to motor unit needs, meaning that individuals must consistently increase the weight to progress.

  • Lifting weights regularly trains the body to generate more motor units and force.
  • General guidelines recommend lifting weights for all muscle groups two to three non-consecutive days a week.
  • Consistency helps maintain muscle mass.
  • Regular progression increases the risk of plateauing.

What They Are

Exercise increases the body’s muscle strength, while sedentariness and inactivity weaken them. A motor unit is a single nerve cell/neuron that supplies the nerves to innervate a group of skeletal muscles. The neuron receives signals from the brain that stimulate all the muscle fibers in that particular motor unit to generate movement.

  • Muscles comprise different fiber types.
  • They are attached to the bones with connective tissue, which is stronger than the muscle.
  • Multiple motor units are dispersed throughout the muscle.
  • The motor units help ensure muscle contraction force is evenly spread throughout the muscle.
  • Motor units are different sizes and operate differently depending on where and what they do.
  • Small motor units might only innervate five or ten fibers. For example, to blink or sniff.
  • Large motor units can comprise hundreds of muscle fibers for swinging or jumping movements.

How They Work

The number of units activated depends on the task. Stronger muscle contractions require more. However, fewer units are needed to accomplish the movement for individuals expending less effort.

Contraction

  • Once a unit receives a signal from the brain, the muscle fibers contract simultaneously.
  • The force generated depends on how many units are required to accomplish the task. (Purves D. et al., 2001)
  • For example, picking up small objects like a pen and paper requires only a few units to generate the force needed.
  • If picking up a heavy barbell, the body needs more units because more force is needed to lift the heavier load.
  • The body can generate more force with stronger muscles.
  • This happens when lifting weights on a regular basis and overloading the muscles with more weight than they can handle.
  • This process is known as adaptation.

Adaptation

The purpose of lifting weights is to challenge the muscles so they adapt to the new challenge and grow in strength and mass. Motor units are a major part of the adaptation process. (Dr. Erin Nitschke. American Council on Exercise. 2017)

  • When first starting weight training, the brain recruits more units every time a muscle is contracted. (Pete McCall. American Council on Exercise. 2015)
  • As individuals continue working out, their ability to generate more force increases and units activate more rapidly.
  • This makes movements more efficient.
  • Individuals can increase motor unit recruitment by consistently increasing the weight challenge to their muscles.
  • The development creates movement memory.
  • A relationship between the brain, muscles, and motor units is established even if the individual stops working out. The pathways are still there no matter how long the individual takes off.
  • When returning to training, the body will remember how to ride a bike, do a bicep curl, or squat.
  • However, the muscles will not have the same strength as the strength needs to be built back along with endurance that may have been lost.
  • It is the movement memory that remains.

Improve Your Athletic Performance with Acupuncture

Acupuncture For Sports Performance

Acupuncture for sports performance follows the same needle insertion for specific points to treat pain symptoms, alleviate inflammation and fatigue, and enhance blood circulation to improve physical and athletic performance. Acupuncture is based on traditional Chinese medicine principles that focus on restoring the balance of the nervous system and body to activate natural healing and increase energy circulation. (Johns Hopkins Medicine. 2024).

  • Acupuncture has become a popular alternative treatment for sports injuries as it has shown positive outcomes and recovery from injuries. (George G. A. Pujalte et al., 2023)
  • The body’s blood and energy pathways, known as meridians, become blocked by inflammation because of illness, injury, or overuse, resulting in pain, stress, and various symptoms. The acupuncture needles stimulate the pathways to clear the blockages, allowing optimal circulation of energy and blood to reduce inflammation and restore balance. (Jiajie Zhu et al., 2021)
  • Sports acupuncture works by maintaining optimal circulation of blood and energy through meridians through the arteries, tendons, muscles, and organs for enhanced productivity and ability. (Liang Kang et al., 2021)
  • Electroacupuncture involves connecting electrical stimulation from a tens machine to specific points over an area to enhance the needle treatment. (Keitaro Kubo et al., 2020)

Acupuncture Can Help

Ways that acupuncture can help include:

Increase Range of Motion

  • Acupuncture can help loosen tight muscles, tendons, and ligaments overused during training or games.(Chi-Tsai Tang, 2023)
  • This allows athletes to perform at peak levels without risking worsening or causing further injury.

Increase Flexibility

  • Acupuncture helps increase elasticity in joints by releasing adhesions within connective tissue for increased mobility.

Improve Reflexes

  • Targeting key points stimulates nerve activity, which can improve quicker reflexes and improve coordination.(Chi-Tsai Tang, Bo Song. 2022)

Increase Circulation

  • Acupuncture increases blood circulation to areas lacking oxygen.
  • This expedites muscle recovery after intense physical exertion.(Keitaro Kubo et al., 2020)

Improve Mental Focus

  • Acupuncture releases endorphins, which reduce pain and also provide an overall sense of calmness and relaxation.
  • This enables athletes to stay focused and motivated throughout training and games. (Chi-Tsai Tang, 2023)

Reduce Fatigue

  • Regular acupuncture for sports performance can help maintain energy levels to help prevent burnout and maintain optimal performance during practice and games. (George G. A. Pujalte et al., 2023)

Relieve Muscle Tension

  • Acupuncture treatment can help relax tense muscles caused by repetitive use as well as from stress tension that could be caused by anxiety before a game or tournament.
  • This helps athletes remain flexible and explosive. (Chi-Tsai Tang, Bo Song. 2022)

For individuals who want to improve their physical performance, sports acupuncture can provide a natural, non-invasive alternative that can help improve athletic performance mentally and physically.

Fine-Tune Your Walking Exercise: Increase Duration or Intensity!

Fine-Tune Your Walking Exercise: Increase Duration or Intensity!

For individuals who have decided to start exercising for fitness and health, walking is a great place to start. Can planning a walking exercise schedule help individuals maintain a fitness routine and improve endurance and speed quicker?

Fine-Tune Your Walking Exercise: Increase Duration or Intensity!

Walking Exercise Planning Schedule

While any amount of walking benefits health, individuals can increase the benefits by walking more per week or by increasing the pace. Brisk walking for 30 minutes per day, totaling 150 minutes per week, is recommended by health experts to decrease risks for heart disease, stroke, diabetes, and other conditions. (Centers for Disease Control and Prevention. 2022)

  • Individuals with ongoing health conditions should talk to their doctor before starting any new exercise program.
  • Beginners are encouraged to focus on using proper walking posture and technique to steadily improve strength and endurance.
  • The increased duration or intensity can help if weight loss is a goal.
  • Improving diet is also necessary for the best results.
  • Individuals can build healthy walking habits by tracking walks.

Schedule

Checklist

  • Individuals can walk outdoors, indoors, or on a treadmill.
  • Wear proper athletic shoes and clothing.
  • Check walking posture.
  • Walk at an easy pace for a couple of minutes before picking up speed.

First Week

An example of what a walking exercise schedule can look like, but it’s advised to consult a professional trainer to develop a personalized fitness plan.

  • Start with a 15-minute walk at an easy pace.
  • Walk five days the first week.
  • Building a healthy habit is the goal, so consistency is important.
  • Spread out rest days, like making days 3 and 6 rest days.
  • Weekly goal – 60 to 75 minutes

Second Week

  • Add five minutes, so the walk time increases gradually.
    Or, individuals can extend more on some days, followed by a rest day.
  • Weekly goal – 80 to 100 minutes

Third Week

  • Add five more minutes with each session, so the walk increases to 25 minutes.
  • Weekly goal – 100 to 125 minutes

Fourth Week

  • Add another five minutes to increase the walk to 30 minutes.
  • Weekly goal – 120 to 150 minutes

Individuals who find any week to be difficult are suggested to repeat that week instead of adding time until they are able to progress naturally. Once able to walk for 30 minutes at a time comfortably, individuals are ready for a variety of different walking exercise workouts to add intensity and endurance. A weekly walking plan can include:

  • Longer walks
  • Higher-intensity walks
  • Speed-building walks

Beginner Walking Speed

An individual’s objective should be brisk walking to achieve a moderate-intensity workout. This is the intensity that is associated with the most health benefits.

Brisk walking should feel like:

  • Breathing is heavier than normal.
  • Able to carry a full conversation while walking.
  • Not out of breath. (Siti Ruzita Mahmod et al., 2018)
  • If the speed is slower and the heart rate is lower during the initial weeks, this is normal.
  1. The first goal is to walk for 30 to 60 minutes a day without injury.
  2. Adding speed and intensity gradually.
  3. Staying consistent in regularly walking before trying to walk faster and longer.
  4. Using proper walking posture and arm motion will help in faster walking.
  5. To reduce the risk of injury, gradually increase the length of the walk or pace, only changing one component at a time.

Individuals may consider joining a walking group or club to have others to walk with and an incentive to maintain regular walking.
