The purpose of this study was to compare the effects of 6 weeks resistance training (RT) with combined RT and loaded change of direction (CD) exercise on muscle strength and repeated sprint ability (RSA) in futsal players. Thirty-four players (age: 23.7 +/- 4.1 years; height: 1.77 +/- 0.06m; body mass: 74.1 +/- 8.2kg) were randomly assigned into three groups: full squat group (SG, n=12), combined full squat and CD group (S+CDG, n=12), and control group (CG, n=10). The RT for SG consisted of full squat with low-load (similar to 45-60% 1RM) and low-volume (2-3 sets and 4-6 repetitions), whereas the S+CDG performed the same RT program combined with loaded CD (2-5 sets of 10s). Estimated one-repetition maximum (1RM(est)) and variables derived from RSA test including mean sprint time (RSA(mean)), best sprint time (RSA(best)), percent sprint decrement (S-dec), mean ground contact time (GCT(mean)) and mean step length (SL) were selected as testing variables. Changes in sprint time and GCT in each sprint were also analysed. Both experimental groups showed significant (P<0.05-0.001) improvements for 1RM(est), RSA(best) and first and second sprint time. In addition, S+CDG achieved significant (P<0.05-0.001) improvements in RSA(mean), sprint time (from fifth to ninth sprint) and GCT (from third to eighth sprint). These results indicate that only 6 weeks of low-load and low-volume RT combined with CD in addition to routine futsal training is enough to improve RSA and strength performance simultaneously in futsal players.
