The effect of static stretching on performance and preventing injury

by

Stretching

Historically many people have used static stretching – a long hold and the end of available muscle length – as a part of a “warm up” routine before sport or exercise. But the research doesn’t back it up, and it may be detrimental.

Let’s talk about performance first. Static stretching actually decreases muscle power for a period of time – the period is debatable, but at least 5 minutes and up to 3 hours – after stretching is performed1,2. This also applies for contract-relax or proprioceptive neuromuscular facilitation (PNF) stretching. This could easily impair athletic performance, especially in sports where high force generation is required. Dynamic exercise/facilitation exercises do not seem to have this power loss effect.

What about injury prevention? Nope, no help there either. A very large study by Lauersen et al. (2014) which synthesises the best quality research surrounding injury prevention to date reported no reduction (or increase) in injury risk for people who performed static stretching3. What they did find was that proprioceptive training, strength training and a dynamic warmup did reduce the risk of acute and overuse type injuries4,5,6.

It’s hard to break old habits, but if static stretching can impair your performance and doesn’t make any difference to injury risk, it may be time to change it up. Athletes can derive a greater benefit by spending that time on a dynamic proprioceptive, agility, strength and balance training program warmup.

If you aren’t about to perform a physically demanding athletic activity and you enjoy stretching, go for it. There is no harm in stretching and if you haven’t got the mobility to perform a sport or task then both static and dynamic stretches are options to achieve this.
