Proposal
Introduction: This study sought to establish typical error (TE) and monitor changes in athletes regarding the following countermovement jump (CMJ) based metrics: Jump height (JH), modified reactive strength index (mRSI), left/right landing impulse (LIL/LIR) and peak power (PP) (W/Kg). Methods: 51 undergraduate collegiate athletes from various sports performed five maximum-effort countermovement jumps (CMJ) with their hands on their hips. This testing process was repeated once per week, for two-to-four weeks. The data was collected using VALD ForceDecks (FDLite). Results: TE was determined to be 7.2%, 11.0%, 12.1%, 23.0%, and 4.6% for JH, mRSI, LIL, LIR, and PP respectively. All metrics recorded for each team remained within TE, with exception to change in JH, mRSI and PP for Women’s Volleyball on week four (decrease by 9.9%, 13.2% and 6.5% respectively). Conclusion: JH and PP have been established as practical measures to monitor changes in the Lancer Varsity Athlete population. These findings will have implications for Lancer strength & conditioning and athletic therapy practices. Future work should establish error for practical, measures that can be utilized to assess changes in landing symmetry. These metrics could be utilized as screening or diagnostic tools for injuries and assist with monitoring progression.
