Effect of different training volumes of repeated sprint ability on mood states in young tennis players

The aim of this study was to analyse the influence of the repeated sprint ability (RSA) training load increase on the mood states in young tennis players. Thirty tennis players (15.78 +/- 1.58 years) took part in this training program (7 weeks). The subjects were divided into 3 groups: G1, specific tennis training and an increase of 8.3% of RSA training volume; G2 specific tennis training and an increase of 16.6% of RSA training volume; G3, only specific-tennis training. The specific tennis training volume was controlled and equated for this period, and all the subjects also filled out a weekly questionnaire to establish the profile of mood states(POMS, Balaguer, Fuentes, Melia, Garcia-Merita & Pons, 1995). The results showed changes in G1 and G2. Whereas tension and fatigue scores increased at the end of the training program in G1 (p <.05), scores of tension, depression, hostility and fatigue were higher at the beginning than at the end of the training program in G2 (p <.05). There were no significant changes in G3 for any variable. The different evolution of subjects' mood states based on RSA training volume performed shows the need for monitoring internal load to fit this training.
