The purpose of this study was to measure the highest value of oxygen uptake during swimming
of middle-aged to elderly women. Ten women (age : 43-70 yrs) , swam in a pool in which a
computerized pacemaker was set. The lighted pacemaker block ran at speeds controlled by a
computer. The subjects swam for 50-m at speeds indicated by the pacemaker. The swimming speed
was increased every 50-m swim with 20-s rest between the bouts. Respiratory gas samples were
collected during the last 30-s period of each 50-m Swim. The highest value of oxygen uptake during
swimming was 27.6±7.2 ml/kg/min, while the peak oxygen uptake measured during walking and
running on a treadmill was 32.2±6.4 ml/kg/min. The relative percent of the highest oxygen
uptake during swimming was 85±9% of the peak oxygen uptake during treadmill exercise. The
highest oxygen uptake of the coach during swimming was higher than the peak oxygen uptake
observed during treadmill running, while the oxygen uptake during sWimming, relatively to the
oxygen uptake during treadmill exercise, was the lowest in subjects who swam at the lowest speed.
These results demonstrated that oxygen uptake during swimming can be measured in middle-aged
to elderly women. Furthermore, the findings suggest that changes in maximal oxygen uptake during
swimming can be used to evaluate the swimming-training effect on an aerobic energy supplying
system of middle-aged to elderly women.
