Stretching Before Exercise Now Considered Harmful, Helpful, Neutral, and 'Honestly We Have No Idea'

A comprehensive systematic review spanning five decades of stretching research has concluded that static stretching before exercise is simultaneously harmful, helpful, neutral, and 'an area in which the scientific community should perhaps stop pretending it has answers.' The review, published in the British Journal of Sports Medicine, analyzed 847 studies on pre-exercise stretching and found that they collectively support every possible position, including several mutually exclusive ones. 'In 1998, stretching was mandatory,' summarized lead author Dr. Patricia Sarcomere. 'By 2005, it was dangerous. In 2012, it was fine again. By 2019, it depended on the type of stretching, the duration, the muscle group, the activity, the ambient temperature, and, in one study, the phase of the moon. We are no closer to consensus than we were in 1974.' Key findings include: static stretching reduces injury risk (six studies), static stretching increases injury risk (four studies), static stretching has no effect on injury risk (eleven studies), and stretching researchers have a statistically significant tendency to cite only the studies that agree with them (all studies). 'The hamstring literature alone is a civil war,' Dr. Sarcomere noted. 'There are research groups that have spent their entire careers arguing about whether a thirty-second hamstring hold improves extensibility or simply increases stretch tolerance. These people do not speak to each other at conferences.' The review's final recommendation — 'do what feels right and stop asking us' — has been criticized by some as 'unscientific,' a characterization Dr. Sarcomere accepts. 'We've been scientifically studying stretching for fifty years and the answer is still a shrug. At some point, the shrug becomes the finding.'
