Why the study?
Do different water exercises performed at the same cadence elicit different oxygen uptake and heart rate responses in postmenopausal women?
Do different water exercises performed at the same cadence elicit different oxygen uptake and heart rate responses in postmenopausal women?
Water exercises performed at a fixed cadence elicit significantly different cardiorespiratory responses depending on the specific movements, suggesting exercise prescriptions should be based on relative effort rather than fixed cadence.
Variable cardiorespiratory demands across water exercises at fixed cadence in postmenopausal women; hypothesis-generating for relative effort-based prescriptions.
The aim of the current study is to analyze and compare oxygen uptake (VO2) and heart rate (HR) in different water exercises. Eight postmenopausal women participated in a set of 4 sessions in water. Eight different exercises were randomly coupled for the 4 sessions. Each exercise was executed at a rate of 60 beats/min for 4 minutes with rest intervals of 30 min. A repeated-measures ANOVA and Bonferroni’s post hoc test were used to test for statistical differences at α < .05. Significant differences were seen in HR and VO2 between some pairs of the 8 exercises. These results suggest that water-exercises classes should be prescribed based on percentages of maximal HR or VO2, not on a fixed cadence, because different exercises correspond to different percentages of maximal effort.
