Phase specific changes in the countermovement jump occur without change in peak metrics following training

The countermovement jump (CMJ) is routinely used to assess changes in strength-power qualities. Common measures derived from this test include height, peak power and velocity. However, valuable information on training induced CMJ performance may be missed if phase subphase variables are not included the analysis also. objective of investigation was determine whether significant can occur absence height or peak-form metrics. Sixteen recreationally trained males undertook 10-weeks resistance consisting weightlifting, ballistic plyometric actions with heavy light loads. performed pre- post-test both metrics mean phase/subphase analysed. Mean velocity (p < 0.01) significantly improved following while = 0.18), 0.29), 0.24) did not. Work, depth, eccentric duration total movement too 0.01 0.03). Practitioners should consider using beyond instantaneous more thoroughly diagnose leg extensors training.
