Study design: Randomized controlled trials. Objective: For upper body exercise, and specifically handcycling, no guidelines for resistance training exist. Therefore, the aim of this study was evaluate the effects of a 7-week resistance training program on submaximal handcycling performance in able-bodied novice male subjects. Methods: Participants were randomly assigned to a training group (n=9) or a control group (n=8). The training group received a 7-week upper body resistance training program (two times a week, three sets of ten repetitions at six exercise stations with an initial intensity of 60% of 1 repetition maximum), whereas the control group did not receive training. Changes in handcycling performance were determined in 3x4 minute submaximal exercise bouts at 20 W, 30 W and 40 W, performed on a motor driven treadmill using a handrim wheelchair with an attached handcycle unit. Oxygen uptake, ventilation, respiratory exchange ratio, heart rate, gross efficiency and rate of perceived exertion were obtained. Changes in strength were determined by a maximal isokinetic arm strength test performed on an isokinetic dynamometer (Kin-Com) for both groups, and by a 1 repetition maximal test for the training group only. Repeated measures analysis of variance was performed on all relevant variables to test for statistical differences (accepted at the p < 0.05 level). Results: Significant increases were found in 1 repetition maximum strength for horizontal row, shoulder press, shoulder pull, and arm curls. No increases in maximal isokinetic strength were found. For all physiological variables (oxygen uptake, ventilation, respiratory exchange ratio, heart rate, gross efficiency), no training effects were found. Overall, ratings of perceived exertion decreased for both the training group and control group. Conclusions: The 7-week upper body resistance training program did not improve important physiological variables characterizing submaximal handcycling performance. One repetition maximal strength increased, whereas no increases in strength were found when assessed with isokinetic dynamometry. Future studies are encouraged to continue investigating different upper body resistance training programs, or possibly combined endurance-strength training, and their effects on handcycling performance, for specific training guidelines to be established to understand, individualize and optimize upper body training.
