Abstract des Autors

This investigation was undertaken to evaluate the aerobic demands during one of the most popular and demanding Swedish folk dances the hambo. Six men andsix women, ranging in age from 22 to 32, participated. Their physical work capacity was investigated on a bicycle ergometer and a treadmill, using two to three submaximal and one maximal loads. All subjects were moderately welltrained and their average maximal oxygen uptake on the treadmill were 2.5 and 3.7 l/min (42.8 and 53.2 ml/kg/min) for women and men, respectively. When dancing the hambo the heart rate was telemetered, and the Douglas bag techniquewas used for measurements of pulmonary ventilation and oxygen uptake. The physical demand during hambo dancing was high in all subjects. Oxygen uptake was 38.5 and 37.3 ml/kg/min and heart rate 179 and 172 in women and men, respectively. Women used 90 and men 70 of their maximal aerobic power obtained on the treadmill. The pulmonary ventilation and respiratory quotient ofthe female subjects were lower when dancing as compared to running, possibly because of voluntary restriction of the movements of the thoracic cage.
