Consequence of feedback-based learning of an effective hand rim wheelchair force production on mechanical efficiency.

摘要: Abstract Objective. Investigation of the effect visual feedback on effective hand rim wheelchair force production and subsequent gross mechanical efficiency. Design. Ten subjects in an experimental group 10 a control practised three weeks ( 3· wk −1 , i.e., pre-test 8 trials) computer-controlled ergometer. Every trial consisted two blocks 4 min at 0.15 0.25 W · kg 1.11 m.s . On trials additional block 0.40 was performed. The with without effectiveness production. Background. In terms, low efficiency propulsion may be result ineffective Methods. During all oxygen uptake, power output, forces torque rims were measured. Results. comparison group, had significantly more compared to (90–97% vs. 79–83%, respectively), but showed lower (5.5–8.5% 5.9–9.9%, respectively). Conclusion. Findings indicate that most from point view is not necessarily efficient way – terms energy cost biological direction based optimization effect. Relevance Learning by useful for increasing propulsion.
