Abstract
Introduction: Physiological capacity is linked to health, mobility and quality of life. Hand cycling is suggested to be a more advantageous propulsion mechanism compared to hand-rim propulsion to maintain and improve physiological capacity. Which improvements can be expected after a 7-weeks hand cycling training program and are the improvements at a local and/or central level? Methods: 22 female able-bodied participants were randomly divided in a training and control group. The training group received a 7-weeks hand cycling training program, 3 times a week at 70% heart rate reserve for 30 minutes confirm ACSM training guidelines. Peak and maximal physiological capacity were measured pre- and post-training with respectively an incremental exercise at the hand cycle (peak values) and a bicycle ergometer (maximal values). The parameters V02, HR, VE, PO, RPE and GE were measured. Results: Compared to the control group, the training group improved significantly on V02peak (+18.1%), POpeak (+31.9%), VEpeak (+31.4%) and HRpeak (+4.0%). No improvements were found in the maximal physiological capacity and GE at a submaximal intensity. The difference between peak and maximal physiological capacity decreased. Discussion: Both peak and maximal physiological capacity could be measured in this population. Though, no central adaptations were found. Populations with lower physiological capacity did show central adaptations after upper-body exercise and could therefore occur in the SCI population. After the training program with ACSM guidelines, a large increase in peak physiological capacity was found. Baseline values and absolute increase of physiological capacity were higher compared to other upper-body exercise and the gap between peak and maximal physiological capacity decreased after training. Physiological capacity at the handbike of able-bodied can be compared with paraplegics, so these findings are partly extendable to the leg impaired population except tetraplegics. Conclusion: Large improvements were found after the training program. Hand cycling is a therefore good alternative to increase and maintain physiological capacity in and after rehabilitation. In this population, mainly local adaptations occur, but the gap between peak and maximal physiological capacity decreased.
