简要总结
To determine changes in quadriceps muscle function following the application of ice and compression to the knee.
详细描述
Novel rehabilitation methods, that specifically target decreased muscle activation due to joint pathology prior to strength training, have elicited greater improvements in muscle function and self-reported disability compared to traditional therapies. Preliminary evidence suggests applying cryotherapy to a joint prior to exercise can increase quadriceps activation. It is unknown if applying cryotherapy and intermittent pneumatic compression can also increase quadriceps force output and voluntary activation. The purpose of this study is to determine changes in quadriceps force output and voluntary activation following the application of cryotherapy and compression. The investigators hypothesize there will be an increase in quadriceps force output and voluntary activation following the application of cryotherapy and compression.

结局指标
主要结局
Changes in quadriceps force output and voluntary activation
时间窗: Baseline and immediately following intervention (Single Study Visit)
Quadriceps activation will be estimated by utilizing the burst-superimposition technique on a maximum voluntary isometric contraction (MVIC) and during a resting condition. The burst-superimposition technique provides the muscle with a percutaneous stimulus to recruit any remaining muscle fibers which have not been stimulated.
