Thirtysix young male soccer players were randomly divided into 2 experimental groups that performed either a single weekly sprint training session (ST1, n = 18, age: 17.2 ± 0.8 years) or two weekly sprint training sessions (ST2, n = 18; age: 17.1 ± 0.9 years) of equal weekly and total volume, in addition to their regular soccer training regimen. Linear sprinting (10 m, 20 m, 30 m, and flying 10 m), T-test agility, countermovement jump (CMJ) and maximal oxygen consumption were assessed one week before (T1), in the middle (T2) and immediately after the 10 weeks of training (T3). A large magnitude and statistically significant main effect for time was found in all the assessed variables after both training interventions (all p 0.05; ES AU - Marzouki, Hamza AU - Ouergui, Ibrahim AU - Doua, Nidhal AU - Gmada, Nebil AU - Bouassida, Anissa AU - Bouhlel, Ezdine SP - 175 EP - 183 DA - 2021 DO - 10.5114/biolsport.2020.97675 UR - http://dx.doi.org/10.5114/biolsport.2020.97675 ER -
