Effects of two warm-up protocols on isokinetic knee strength, jumping ability and sprint swimming performance in competitive swimmers

The purpose of this study was to examine the effects of different dryland warm-up protocols on knee isokinetic strength, vertical jumping, and sprint performance in competitive swimmers. Twenty-four male swimmers were randomly assigned to the FIFA 11 + group (n = 12) or the post-activation performance enhancement (PAPE) group (n = 12). The FIFA 11 + group performed the FIFA 11 + warm-up program three times per week for 6 weeks, whereas the PAPE group consisted of performing general activities and three sets of five drop jumps. Performance test included concentric (con) and eccentric (ecc) isokinetic strength of the quadriceps (Q) and hamstrings (H) of the dominant (DL) and non-dominant (NDL) limbs at three angular velocities, countermovement jump (CMJ), squat jump (SJ) and a 50-m time trial. The conventional (Hcon: Qcon) and functional (Hecc: Qcon) ratios were calculated pre- and post- intervention. The FIFA 11 + group showed a significant increase in DL-Hcon (p
