Why are Stretching Exercises Helpful?
Did you know that vigorous exercise encourages the shortening and tightening of your muscles? Stretching exercises encourage lengthening of your muscles and their associated tendons to normal your muscle length tension ratio.
Muscles shorten with use during exercise, general postural habits and are more likely with ageing and disuse. If you only use a small range of your muscle length range, your muscle will adapt over time and shorten to that length under premise of “use it or lose it” that your body naturally attunes itself.
How Do Stretching Exercises Help?
By lengthening your muscles via stretching, you promote flexibility and your ability to have a full range of motion about your joints.
Studies comparing a warm-up that includes static stretching with a warm-up that does not include static stretching have shown that, although pre-exercise static stretching does improve flexibility, it does not appear to prevent injury during exercise. Therefore, the type of pre-exercise stretching technique needs to be an active style of stretch to prepare you for high load muscle activity during your sport rather than solely for tissue elongation.
Not taking time to stretch, especially after exercise, can mean losing your ability to move freely or to perform the activities that are basic to your sport or daily needs.
How to Stretch Properly?
It is important to stretch your muscles only when they are warm, as cold muscles are more likely to tear. The stretches that you perform vary depending on whether your are preparing for exercise, recovering form exercise or rehabilitating from injury.
Here are some general stretching guidelines.
What Stretches Should You Do Before Exercise?
Before you exercise it is a good idea to warm up your muscles to prepare you for the rigors of exercise.
You could think of warming up like a car engine; you want to warm it up before your roar down the street.
The ideal pre-exercise stretching program includes a general warm up eg light 5 minute jog until you can feel some warmth in your muscles.
Then, you can perform some slow sustained static stretches ideally for 20 to 30 seconds. Your stretching exercises should be modified by increasing their speed and power in a progressively graduated order that prepares you for the skills and muscle demands for your sport or chosen exercise session.
By the end of your warm up you should be performing plyometric or bounce style exercises that replicate your sport’s requirements.
Stretching After Exercise
An ideal time to do most of your static stretching is after exercise, that is, immediately after your post-exercise cool-down. Allow around 5 to 10 minutes to stretch after exercise, and concentrate on the muscles that you have just exercised. Use the static stretches rather than bouncing style stretches. Stretching at this time helps restore your muscles to their resting length and prepare them for your next exercise session.
A light static stretching routine (stretching a muscle and holding it in this position without discomfort for 20-30 seconds) can be performed at the end of a warm-up, before undertaking more vigorous activity. Be sure to stretch each of the muscle groups you will be using in your chosen activity 2 to 3 times.
Corrective or Rehabilitation Stretching
Specific stretching for target muscles that have been identified by your physiotherapist should be performed daily or as directed by your therapist using the techniques that they feel will assist you to reach your flexibility goals.
Warming up for a dedicated stretching session might involve 2 to 3 minutes of jogging or doing your favourite exercise at low intensity for 5 minutes. Raising a light sweat will indicate warming of your muscle tissue.
Alternatively, attending a yoga class is an enjoyable way to contribute to the flexibility part of your fitness programme.
Stretching Exercise Styles
Static stretching is considered the safest method of stretching. A static stretch should be held for 20 to 30 seconds at a point where you can feel the stretch but do not experience any discomfort. If you feel discomfort, ease back on the stretch. Do not bounce when holding the stretch.
Dynamic or Ballistic Stretching
Ballistic stretching as stretches performed at speed and prescribed by your sports physiotherapist or elite sports coach. They are often used as a part of your warm-up for sport or training.
Dynamic stretches involve muscle movements that move a joint through the full range of movement that will be required in your chosen sport or activity.
For example, if your chosen activity requires sudden bursts of power, such as jumping or sudden acceleration, then specific ballistic stretches under the direction of your physiotherapist or coach may be advised as a part of your warm-up.
Proprioceptive Neuromuscular Facilitation (PNF) Stretching
Proprioceptive Neuromuscular Facilitation or PNF stretching involves a component of stretch - muscle contraction - and further stretch. This process is usually repeated several times and uses a trick on the muscle spindle reflex to help elongate your muscles
The technique of PNF stretching was first developed as a muscle therapy but is now used by athletes as a means of enhancing flexibility. PNF stretching is often used by physiotherapists. More information can be sought by seeking their advice in your situation.
Stretching Exercises - Summary
Stretching can be used as a corrective, preventative and recovery strategy. More specific stretching advice can be sought from your physiotherapist.
