Abstract:
Three groups of untrained males and two groups of untrained women (aged 20...49 years) carried out one-arm cranking with defined loads. All derived parameters of the cardiopulmonary and motor systems showed a load-dependent behaviour. There were sex-differences in heart rate, oxygen uptake and iEMG. The physical endurance limit was determined by 10 watts for males and 5 watts for women.
