Abstract

Background The role of the pacing strategy has been proven to be very important to performance in sports. For wheelchair dependent, in activities of daily life (ADL), pacing is very important for the prevention of premature exhaustion during a single task or over a longer period during the day. The purpose of this study was to evaluate the effects of pacing in a hand cycle task, to investigate if a learning effect occurs and what the effects of training are on the pacing strategy. Method Twenty-two able-bodied participants were randomly assigned to a training group and control group. The training group had a 7-week training, three times a week at 70% heart rate reserve (HRR) for 30 minutes. The control group did not receive training. All participants did three 6-minute hand cycle tests (6-MHT) and a maximal exercise test before and after the period of 7 weeks. The distance hand cycled, velocity and RPE were analyzed to determine the pacing strategy. All outcome variables were analyzed with ANOV A for repeated measure (p<0.05). Results All participants increase distance between trial 1 and 2 (873 ± 106m vs 918 ± 109m, p<0.001), but not between trial 2 and 3 (918±109m vs 937±105m, p=0.078). The training group increase between trial 3 and 4 (909±92m vs 1124±108m, p<0.001), the control group did not. The pacing strategy for the training group did not differ between trials 1-6 (F2.s,2s.4= 1.284, p=0.299). The control group did change the strategy (F3.s,3s.3= 4.358, p=0.007) and paced more eager at the pretests and more even at the posttests. The RPE did not change between trials for both groups. Conclusion The best performance resulted from a fast start with reserve energy for an end spurt. This reserve energy will help prevent premature exhaustion in ADL setting. The estimation of the distance can be learned and will improve distance covered. It will not adjust the template of correct pacing. The effect of training is mainly an improvement of physical capacity; it will lead to less strain, but does not change the pacing strategy.
