To stretch before or after a session of physical exercises would not warn the stiffness. It is what the results of an analysis of tests cliniques1 that of the researchers of the university of Sydney, in Australia, have just published indicate.
According to the researchers, these results put an end to a debate that persists since several years. Some affirm that the stretches contribute to warn the stiffness, to improve the physical performances and to warn the injuries, the other put in doubt such an assertion.
Let’s specify that the Australian analysis was only about the effects of the stretches on the stiffness and no on the performance or on the prevention of the accidents. The researchers analyzed the results of ten clinical tests led by 190 topics of which the average of age voisinait the young twenty (79 women and 111 men).
According to their results, the practice of stretches, before or after a session of intense physical activity, only has a marginal effect on the stiffness. The stretches practiced before the exercise would have reduced the stiffness of the order of 0,5% while, practiced after the exercise, they would have dragged a reduction of 1%.
According to one two authors of the survey, Marcos of Noronha, those that make some stretches to attenuate the stiffness exhaust themselves uselessly. ” The stretches are not harmful, but he/it is now clearly established that they don’t contribute to warn the stiffness” meaningfully, he/it specifies.
The other author of this survey published in the prestigious Cochrane Database of Systematic Reviews, the professor of physiotherapy Robert Herbert, had already published, in 2002, an analysis arriving to similar results,
