Effects of a low-intensity conditioning programme on V˙O2max and maximal instantaneous peak power in elderly women
Abstract The effects of 12 weeks of a low-intensity general conditioning programme on maximal instantaneous peak power ( W˙peak ) and maximal oxygen uptake ( V˙O2max ) were examined in 20 elderly women . After medical , familiarisation , and ethical procedures , the subjects were r and omly divided into either a training and or a control group . The training group [ n = 11 ; mean ( SD ) age 63.0 ( 3.1 ) years ] agreed to take part in a 12-week training programme at an exercise intensity kept under 60 % of the heart rate reserve for about 60 min , 3 times a week . The control group [ n = 9 ; mean ( SD ) age 63.5 ( 3.3 ) years ]  did not perform any particular physical training . Before and after the training period , all participants underwent  anthropometric measures  and a  maximal cycling test  to exhaustion to measure their V˙O2max . In addition , W˙peak was determined 1 week later by the subjects performing a vertical jump from a squatting position on a force platform . Following training , neither the anthropometric characteristics nor the V˙O2max changed in either of the groups . In contrast , W˙peak increased significantly ( P < 0.001 ) in the training group , but did not change in the control group . This result could be interpreted as the result of an improved level of neuromuscular activation . Furthermore , it shows that although muscle power declines with age at a faster rate than does aerobic power , its sensitivity to training seems to be higher than that of the aerobic system
Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
