Countermovement jump standards in rugby league : what is a “good” performance? (2020)
Journal Article
McMahon, J., Lake, J., Dos'Santos, T., Jones, P., Thomasson, M., & Comfort, P. (2020). Countermovement jump standards in rugby league : what is a “good” performance?. Journal of Strength and Conditioning Research, 36(6), 1691-1698. https://doi.org/10.1519/JSC.0000000000003697

The countermovement jump (CMJ) is considered an important test in rugby league and the force platform is the recommended tool for assessing CMJ performance in this cohort. Due to inconsistent methods applied across previous studies, there is curren... Read More about Countermovement jump standards in rugby league : what is a “good” performance?.
