With age, those who spend a lot of time sitting at a desk and do some sports are more difficult to move.
Strength exercises and stretching can alleviate the problem.
Regular stretching helps muscles stay strong. In runners, it means that their are not safer, their movement more fluid and more upright posture.
Stretching conscientious improve power over time.
They reduce muscle tension or muscle stress. After training, they help to reduce the contraction caused by exercise.
After a race, they accelerate the decline in lactate and thus promote better muscle regeneration.
Before training, they are often harmful. Indeed, in addition to relax the muscles, they stop their self-protection mechanism, which encourages them to strive to support the effort and reduce the risk of injury.
In case of physical asymmetry, it is better to seek to strengthen the region shortened (neglected) rather than stretch.
