Abstract

The purpose of this study was two-fold. First, to examine the impact exercise-induced muscle damage (EIMD) on physical fitness qualities following a basketball-specific training session. Secondly, to determine the reproducibility of the sport-specific performance measures in elite female basketball players. Ten elite female basketball players (age 25.6 ± 4.5 years; height 1.8 ± 0.7m; body mass 76.7 ± 8.3kg) undertook a 90-minute training session involving repeated jumping, sprinting and game-simulated training. Indirect muscle damage markers (i.e., countermovement jump [CMJ], delayed-onset of muscle soreness [DOMS] and creatine kinase [CK]) and sport-specific performances (i.e., change of direction [COD] and suicide test [ST]) were measured prior to and 24 hours post training. These measures were also collected one week following training to determine the reproducibility of the basketball specific performance measures. A significant reduction in lower-body power (-3.5±3.6%; P<0.05), whilst a significant increase in DOMS (46.7±26.3%; P<0.05) and CK (57.6±23.1%; P<0.05) was observed 24 hours post exercise. The ST was also significantly increased (2.1±1.8%; P<0.05), although no difference was observed for COD (0.1±2.0%; P>0.05). The intra-class correlation coefficient and coefficient of variation for the COD and ST were 0.81 and 0.90, respectively, and 1.9% and 1.5%, respectively. In conclusion, appropriate recovery should be considered the day following basketball-specific training sessions in elite basketball players. Furthermore, this study showed the usability of performance measures to detect changes during periods of EIMD, with acceptable reproducibility and minimal measurement error.
