Army physiotherapist Rod Pope, working with colleagues at the University of Sydney and Charles Sturt University in Wagga Wagga, has monitored more than 2600 army recruits over a year in randomised, controlled trials. Some of the recruits stretched particular leg muscles before exercise; others did not. Yet there were no differences in injury rates between the two groups—and not just because too few recruits in either group became injured to register a significant effect. “We were able to rule out even a quite small effect of stretching,” says Pope. “This has not been properly researched before,” he explains. “Stretching was assumed to work in preventing injury, but there was no evidence to suggest it did.” The work has been accepted for publication by Medicine and Science in Sports and Exercise, the journal of the American College of Sports Medicine. “We are telling the army to no longer stretch,” says Pope. “But it’s a long tradition and tradition dies hard.” Despite this advice, Pope stresses that it is important to stretch muscles which are tight and could restrict the normal range of movement. He also suspects that stretching after exercise could be beneficial—although this has not been fully investigated. “There is no evidence that points unequivocally one way or the other,
