What is Mobility?


Let's first dive into a simple explanation of mobility. When you prepare your shoulders to exert force before throwing a baseball to reach the other side of the field, that's your mobility. All it takes is a lot of force from your body; you're good to go.

Mobility refers to your ability to move muscles and joints with stability and control through a full range of motion. The National Library of Medicine defines mobility as the patient's ability to control and change their body position. Remember that physical mobility requires sufficient muscle energy, strength, neuromuscular synchronization, skeletal stability, and joint function.

Speaking of joint function, mobility is associated with joint health as it provides lubrication, nutrition, stability, and injury prevention to your joints. Mobility is your guiding force in using your joints and keeping them healthy.

What is Flexibility?


Massachusetts Institute of Technology emphasized Gummerson's definition of flexibility as "The absolute range of movement in a joint or series of joints that is attainable in a momentary effort with the help of a partner or a piece of equipment".

But simply, flexibility occurs when you're someone doing a split or you're a professional gymnast or ballerina who tries several flexible styles to move your body freely. Flexibility allows your muscles and tendons to stretch and lengthen passively through a range of motion. Muscles elongate and contract more effectively when flexible, making muscle flexibility crucial for proper joint movement and function.

Flexibility is divided into two types: static and dynamic. Based on the definition from deVries in 1976, static flexibility, through a wide ROM (range of motion), refers to the ability to flex and extend a joint. On the other hand, dynamic flexibility, with little resistance to the movement, is the ability to flex and extend the joint quickly despite the ability to achieve an extreme ROM.

Key Differences Between Mobility and Flexibility

Knowing the difference between mobility and flexibility, it's best to remember them through key terms: mobility = joint movement, while flexibility = muscle length.

Aside from achieving an active joint function through control and stability, mobility also involves flexibility, strength coordination, and neuromuscular control of muscles and tendons to effectively perform movements.

Flexibility mainly focuses on the extensibility of muscles and tendons. By allowing the muscles to stretch without undue resistance, flexibility helps prevent muscle strains and injuries.

Scientific Studies and Data

Recent Research on Mobility

Recent studies are showing the impact of mobility exercises on athletic performance.

A 2020 study published in the European Journal of Human Movement concluded that hip mobility exercises can be beneficial for sprint-related skills through warm-up protocols and it is likely to be helpful for hip mobility to be maximized to athletes which make running performance as integral parts of their sports.

Another recent study from Scientific Research Publishing showed the significance of hip mobility and flexibility for non-contact-sport athletes, specifically those in the track and field, which can impose effects on injury performance and athletic performance.

The researchers recommended performing the program with at least 24 hours breaks in-between each time through 3 times a week. The range of motion of the hip, after at least 6 weeks, can be expected to improve. Other results include comfortable kicking resulting from longer swing time and longer running strides.

Recent Research on Flexibility

Recent studies show the difference between static and dynamic stretching and which is more effective and interrelated with flexibility. A 2020 study published in the National Library of Medicine showed support for the use of dynamic stretching as a strategy to avoid decreased power production during repeated cycling sprints in a warm-up. But, static stretching provided no such benefits, having the same portion as dynamic stretching. This study was tested on the performance of female handball players.

Another study from the University of Texas at Arlington showed that range of motion in the low back and hamstring flexibility, ankle plantar flexion, and dorsiflexion can significantly be affected by static stretching training programs when measured by the Sit and Reach Test.

Results showed that children in age 8 to 11 years old can experience more gains in athletic performance in a three-session static training program than dynamic stretching.

In terms of flexibility training and its impact on muscle strength, a 2014 study suggested that active individual muscle stretching (AID) shows a temporary decrease in muscle output strength while there's an increase in flexibility.

In a different study from Canadian Science Publishing, stretching within a warm-up is recommended, with additional post-stretching dynamic activity, for increasing joint range of motion (ROM) and for reducing muscle injuries with inconsequential effects on subsequent athletic performance.

Improving Mobility and Flexibility

Mobility Exercises

Mobility Exercises

Effective mobility exercises can always begin with dynamic stretches and joint mobilization techniques. Dynamic stretches, as a type of mobility exercise, allow you to move your joints and muscles through a range of motion in a repetitive and controlled manner.

These stretches usually prepare your body for movement, improve flexibility and mobility, and increase blood flow to the muscles, which are done before a physical activity or workout.

Examples of dynamic stretches are:

  • arm circles
  • leg swings
  • hip circles
  • high swings
  • butt kicks

On the other hand, joint mobilization techniques are manual therapy methods used to reduce pain, improve the range of motion, and enhance the function of particular joints.

According to Advance Physical & Aquatic Therapy, joint mobilization exercises can be considered through tibia femoral glide, long axis distraction, flexion, extension, patella motion, and other lateral rotation and movement. Take note that chiropractors and trained physical therapists usually perform these techniques.

Flexibility Exercises

Flexibility Exercises

Also known as stretching exercises, flexibility exercises are designed to increase your range of motion in the joints and improve the flexibility and length of your muscles. Implementing flexibility exercises into your daily routine can alleviate muscle tension, reduce the risk of injury, and improve overall mobility.

Well-known flexibility exercises are static stretching, PNF stretching, and yoga. Static stretching can include stretches in the hamstring, quadriceps, calf, shoulder, and triceps. PNF stretching or Proprioceptive Neuromuscular Facilitation is usually done with a partner and involves relaxing and contracting muscles to increase their length.

PNF stretching can be done with hamstring PNF and quad PNF. Lastly, yoga and pilates are essential to improve balance, flexibility, and strength. Types of yoga include child's pose, downward dog, leg circle, and cat-cow.

Common Myths and Misconceptions

Debunking Myths

Mobility and flexibility are significant in keeping our body healthy and free from early signs of health conditions and aging. However, some may start to have unrealistic expectations regarding exercises related to mobility and flexibility. This may be due to the growing influence of social media and peer influence.

With that being said, we'll debunk some of the common myths:

  • Flexibility is only for athletes and dancers

No scientific evidence has proven this statement to be true. Keep in mind that flexibility is applicable for everyone to reduce the risk of injury, improve daily movements, and enhance overall well-being.

  • Stretching eliminates muscle soreness

While stretching can relieve muscle tightness, it may not completely lessen muscle soreness, mainly when it's caused by intense exercise. A review by Herbert and Gabriel shows that stretching has no protective effect on the risk of injury or muscle soreness before and after workouts.

  • Only young people can improve flexibility

Regardless of age, you shouldn't be demotivated to improve your flexibility. Maintaining flexibility becomes more important as we age to reduce the risk of falls and prevent joint stiffness. Researchers recommended in a 2018 study that pre-frail and frail older adults should include multi-component activities like flexibility, aerobic, and balance tasks.

  • Stretching before a workout decreases performance

Stretching before a workout will only help your muscles relax after workout and to increase flexibility. According to a 2012 study published in the National Library of Medicine, static stretching performed before or after warm-up doesn't decrease strength.

Practical Tips for Everyday Life

Daily Mobility Routines

Daily mobility routines are a convenient way to ensure your joints stay active to reduce muscle tension, improve flexibility, and enhance overall well-being.

  • Upper body stretching

Sit on the edge of your chair with your feet flat on the floor. Clasp your hands behind your back and gently squeeze your shoulder blades together while opening up your chest.

  • Shoulder mobility

For arm swings, sit or stand with your hand in a neutral position. Then, gently tilt your head to one side, bringing your ear toward your shoulder. Before repeating on the other side, hold for a few seconds.

  • Ankle mobility

To improve ankle mobility, alternate lifting your toes and heels off the ground while seated.

Flexibility for Relaxation

The United Nations High Commissioner for Refugees (UNCHR) recommended yoga and tai chi for stress relief as a relaxation technique. Combined with deep breathing, yoga involves a series of both stationary and moving poses. Aside from reducing stress and anxiety, yoga can improve balance, stamina, strength, and flexibility.

Here are some types of yoga as recommended by the UNCHR:

  • Satyananda

Features deep relaxation, meditation, and gentle poses, making it suitable for anyone looking for stress reduction and beginners.

  • Hatha yoga

Also suitable for beginners, which refers to a reasonable, gentle way to relieve stress.

Tai chi refers to a non-competitive series of slow, flowing body movements that are self-paced. These movements focus on relaxation, conscious circulation of vital energy, and concentration.

Tools and Equipment

Foam Rollers

Also known as a self-myofascial release (SMR) technique, foam rolling promotes relaxation, alleviates muscle tension, and improves flexibility by targeting tight areas and trigger points in the fascia and muscles.

Here are simple steps to use foam rollers for muscle relaxation and myofascial release:

  1. Choose the right foam roller
  2. Look for a comfortable space
  3. Target the muscle group
  4. Proper body position
  5. Roll slowly
  6. Breathe and relax
  7. Gradually increase pressure
  8. Cover the entire muscle
  9. Be cautious of sensitive areas
  10. Spend enough time
  11. Stretch and hydrate
  12. Frequency of foam rolling

Resistance bands

Resistance bands are made of elastic material for versatile exercises that provide resistance when needed. They're accessible in different resistance levels, lengths, and thicknesses to exercise goals and accommodate different fitness levels.

Here are some exercises that you can do with a resistance band:

  1. Front squat
  2. Leg extension
  3. Prone (lying) leg curl
  4. Standing adduction
  5. Lateral band walk
  6. Seated adduction
  7. Concentration curl
  8. Overhead triceps extension

Expert Opinions and Interviews

Mobility and flexibility are essential in ensuring that muscles and joints work for our daily physical movements, specifically when engaging in sports and exercises.

Listen to what experts like yoga instructors, athletic trainers, and physiotherapists have to say about mobility and flexibility:

"So much of Yoga is moving through big ranges of motion, and cycling through mobility work, dynamic and static stretches, all of which has been proven to improve flexibility."
- Laura Peace, Senior Breathwork, Yoga Teacher, and the Founder of Yoga Collective London

"We believe that the definition of mobility is to have a combination of flexibility, strength and motor control. That is, to be truly mobile, you need to be able to have the strength to control your flexibility."
- Steve Sahl, Sports Physiotherapist and Director of Education 

"If basic static stretching is too boring, try some other popular methods. Such as yoga, Pilates, or tai chi." - Dominique Gummelt, PhD, Certified Personal Trainer and Wellness Practitioner
