Measurement of pedal loading in bicycling: II. Analysis and results.

摘要: Abstract A computer-based instrumentation system was used to accurately measure the six foot-pedal load components and absolute pedal position during bicycling. The is first of its kind enables extensive meaningful biomechanical analysis With test subjects riding on rollers which simulate actual bicycling, pedalling data were recorded explore four separate hypotheses. Experiments yielded following major conclusions: (1) Using cleated shoes retards fatigue quadriceps muscle group. By allowing more flexor utilization backstroke, distribute workload alleviate peak demand group; (2) overall efficiency increases with power level; (3) non-motive apply adverse moments knee joint are significant magnitude; (4) an invaluable training aid. One subject reduced his leg exertion at by 24 per cent.
