Using knee wraps for squats increases wear and tear in your knee joint

Knee wraps

If you use knee wraps during strength training you can generate more power in your lower body. This has been officially known since 1990 [J Strength Cond Res 12: 30–35, 1990.], but long before this strength athletes had worked out that they could do heavier squats by using the things. It's probably the elasticity of the material that helps.

Study

Little was known however about the effect of wearing knee wraps on how you carry out a squat. That's why sports scientists at the University of Chichester got 10 experienced male strength athletes to perform squats with [Wrapped] and without knee wraps [Unwrapped].

















Results



As the weight was lowered [from a to b] the horizontal component of the movement decreased by 39 percent; as the weight was raised [from c to d] the horizontal movement decreased by a massive 99 percent.

As a result of the reduction in horizontal movement, the researchers suspect that friction in the knee joint increases, leading to more wear and tear.

This effect is reinforced because the knee wraps help the athletes to perform the movement faster: power increases.









Conclusie

"We therefore propose that knee wraps should not be worn during the strength and conditioning process and that if an athlete feels that additional support is needed for the knee, the integrity of the joint is thoroughly assessed and treated rather than relying on artificial aid that could exacerbate any underlying issues", the researchers write.
