What can you do to improve flexibility?

improving-flexibility-strive-physioThe good news is you can improve muscle flexibility and joint range of motion through stretching, despite physiological and other factors.

But what type of stretching is best?

Stretching can be grouped into 3 key types and all of these are important in keeping your muscles and joints at an optimum.

Dynamic stretching are slow, controlled movements

Dynamic stretching helps the muscles to stretch through their optimal length and take the joint through a full range of motion prior to doing an activity.

It targets the most intensely used muscles in the activity, increasing their elasticity and as a result reducing injury risk due to muscle sprain/strain. An example would be hamstring swings for runners prior to running.

Static stretchingis where a muscle is held in a lengthened position for 20-30 seconds.

It is ideal for stretching connective tissue and helps lengthen a muscle. It is best to be used as a cool down after an activity. An example is a hamstring stretch after running.

3.  Proprioceptive neuromuscular facilitation (PNF)

Proprioceptive neuromuscular facilitation (PNF) is a type of stretching that promotes elongation of muscle tissue.

It aims to optimise the neuromuscular ‘stretch reflex’ response of the body. This involves stretching a muscle passively to its end of range, then either holding or contracting the muscle for 6 seconds, releasing and then stretching the muscle further to a new range, repeating 3-4 times. Yoga and pilates exercises are a form of PNF stretching.

Important to do 3 forms of stretching

To optimise the flexibility of your muscles and joint ROM, it is important to do all 3 types of stretching.

To improve flexibility I recommend …

1.dynamic stretching prior to exercise

2. static stretching after and

3. doing a session of yoga or pilates once a week

Or, make time for a good PNF stretch program once a week to keep you supple.

Tips to remember when stretching

• Always warm up before stretching. Stretching when your muscles are cold could lead to injuries.

• Stretch to the point where you feel some mild tension. You should not feel pain. If you do, stop and release the stretch. Try again in a shorter range, build up to the increased range.

Flexibility: why it is important

exercise-improves-flexibilityFlexibility is important in day-to-day activities and sports. It allows for greater comfort and ability  – and reduces your risk of injury.

To initiate movement, your muscles contract (shorten).  How well they contract will depend on the initial resting length of the muscle.

And, for any movement, there is an optimum resting length to gain the optimum contraction your muscles.

For example …

Turning your head

Turning your head while driving is something we do regularly. This requires optimum resting length in your neck muscles and a muscle contraction.   If the resting length of your neck muscles is less than optimum (shortened) , you won’t be able to turn your head to the desired range.

When you can’t turn your head it means some muscles are too tight and the optimum tension is not correct.

Bending over

Think about bending over to touch your toes. If you can’t bend over like you used to, your hamstrings may be too tight and need lengthening.

What is flexibility?

Flexibility refers to the mobility of your muscles and is defined as the Range Of Motion (ROM) of your joints or the ability of your joints to move through different planes.

There is a balance between the initial resting length of a muscle and the contraction of a muscle to build the right tension to move your joints.  This impacts on the joint range of motion.

  • If the resting length of a muscle is too long, or too short, it will affect the ability of the muscle to contract.

Why is flexibility important

Improves skill level

Good muscle and joint flexibility allow your joints to accommodate all the different angles required for everyday movements or sport-specific movements.

Decreases risk of injury

A balance between the length versus the tension of muscles reduces your risk of injury, particularly muscle tears or sprains.

There are several groups of muscles that show a tendency towards tightness.

These include the:

  • hamstrings
  • calf muscles
  • pectoral muscles and some
  • back muscles.

These muscles are often implicated in musculoskeletal pain, especially back pain and are prone to strains.

Increases efficiency

When muscle length and muscle contraction are optimised, you can obtain maximum muscle power and efficiency for your chosen sport or activity.

For example, when running …

If you have optimal length and tension in hamstrings, quads, hip flexors and gluteal muscles when you are running, this allows for:

  • an increase in speed
  • less fatigue over longer distances
  • overall enhancement of your running enjoyment due to less pain in your legs and lower back

Flexibility can be limited by …

High muscle tone

High muscle tone occurs when the muscle is overworked or tense. Nerves supplying the muscle continue to provide a low-level discharge. This means the muscle cannot fully relax so the resting length is altered. This limits the full range of movement of the joint to which the muscle is attached.

Stretch reflex

As a muscle is rapidly stretched there is an automatic neuromuscular response – the ‘stretch reflex’ which limits overstretching to prevent injury. Where the length and tension relationship of a muscle is reduced, this reflex can start earlier, limiting the joint’s range of motion.

Change in muscle and connective tissue

As we age, muscle fibres are gradually replaced with fibrous connective tissue which is less elastic. This increases the stiffness of the joint, limiting the range of motion of the joint, particularly in highly mobile joints such as the shoulder and hips.

Bony change

Bony changes in the joints due to ageing or injury can affect how the surfaces of the joints line up decreasing flexibility and decreasing joint range of motion.

Poor posture

Poor posture can reduce the optimum length and tension relationship of skeletal muscle leading to stiffness in the joints as they are prevented from moving through their full ROM.

Try this activity and see if you notice the difference in your arm’s range of motion.

  1. Sit in a slumped position and raise your arms up over your head.
  2. Now sit on your sit bones, stack your spine up long and now raise your arms up overhead.
  3. Do you notice the difference?

Previous injuries

Injuries to muscles and connective tissue can lead to a thickening (fibrosing) of the soft tissue. Fibrous tissue is less elastic and can lead to decreased resting length of the muscle and reduced range of movement (ROM) in the affected joint.
