Objective The aim of this research was to investigate the variation of Intermittent and Maximal Voluntary Contraction (IMVC) with (WR) and without racquets (WoR) in relation to specific weight training protocol in a group of wheelchair tennis athletes. Methods Twelve wheelchair tennis athletes were divided in experimental group (EG, age 42±12 years, weight 63±16 kg, height 170±18 cm, period of training 5±3 years) that in addition to tennis training (twice a week), followed a weight training protocol for four weeks (twice a week); the control group (CG, age 44±8 years, weight 79±17 kg, height 175±7 cm, period of training 10±4 years) did not change their tennis habits. Strength performance was evaluated at the beginning (T0) and after (T1) one month of training to verify the effects of weight training with two specific isometric test: 1) The first consisted in 3 MVC separated of 3 minutes of recovery. The best reps was chosen to calculate statistical variations. 2) The second consisted in 10 maximal concentric repetitions lasting 3 seconds with a 3-second pause between each one. The strength was measured using the TESYS System (Total Evaluation System, Globus, Treviso, Italy) which was connected to a load cell. Results Data analysis (T0 vs T1, Wilcoxon test) showed a significant increase in EG: MVC WoR (p<0.05, +16%), MVC WR (p<0.05, +11%), IMVC WoR (p<0.05, +8%) and IMVC WR (p<0.05, +7%). No significant changes were observed in CG. Conclusion The human body benefits of the ability to adapt as a result of specific muscle stimulation (Jones et al. 1989, Mujika and Padilla 2001): four weeks of weight training modify significantly physical efficiency in wheelchair tennis athletes.
