voglio precisare che quanto finora scritto non sono mie opinioni ma solo il frutto di recenti studi scientifici pubblicati su riviste mediche:
To stretch or not to stretch: the role of stretching
in injury prevention and performance.

is commonly practiced before sports participation; however, effects on subsequent performance and injury prevention are not well understood. There is an abundance of literature demonstrating that a single bout of stretching
acutely impairs muscle strength, with a lesser effect on power. The extent to which these effects are apparent when stretching
is combined with other aspects of a pre-participation warm-up, such as practice drills and low intensity dynamic exercises, is not known. With respect to the effect of pre-participation stretching
on injury prevention a limited number of studies of varying quality have shown mixed results. A general consensus is that stretching
in addition to warm-up does not affect the incidence of overuse injuries. There is evidence that pre-participation stretching
reduces the incidence of muscle strains but there is clearly a need for further work. Future prospective randomized studies should use stretching
interventions that are effective at decreasing passive resistance to stretch and assess effects on subsequent injury incidence in sports with a high prevalence of muscle strains.
peccato che in questi giorni non ci sia fisioandrea, "reduce" dalla maratona di NY...
lui potrebbe darci ulteriori spiegazioni...aspettiamo il suo rientro
