Decrease and restoration of jump test performance following a combined exercise-based training session among students playing basketball

The use of training sessions which combine with strength exercises and sprints (CO training sessions) to improve the Repeated Sprint Ability (RSA) requires that athletes manage well recovery times. This study aimed therefore at measuring the decrease in performance at jump tests, induced by a CO training session and estimating the level of restoration reached after 48 hour-recovery period. Seventeen students playing basketball (20.8 ± 3.7 years) took part in this study carried out using a 2 x 5 experimental design, with a control training session made up of traditional basketball exercises (TR), and after seven days, came a CO. The Squat Jump (SJ), counter movement jump using arms or not (CMJ and CMJA), Reactivity Jump (RJ) were carried out before, at the end, six hours, 24 hours and 48 hours after each session. The CO session induced the decrease in performance by 12.7%, 12.3%, 6.7% and 22.9% (p < 0.05), respectively for SJ, CMJ, CMJA and RJ, without a complete recovery of the muscular capacities after the 48 hour-resting period. After the TR session, the modifications in jump performances recorded were all non-significant (p > 0.05). A CO training session caused a decrease in the performance of jump tests, like that induced by a strength training complex session. After a 24 hour-resting, the Reactivity Index (RI) was closed to the initial value, but 48 hours after, the restoration of the other muscular parameters was incomplete in the studied basketball players.
