Heart rate (HR) and oxygen uptake (VO2) measured during water aerobics (WA) were compared to maximal values obtained during an incremental treadmill test to assess the energy demand and potential cardiorespiratory (CR) training effects of WA. Sixteen college-age females served as subjects (mean +/- SD = 20.4 +/- 1.6 years). WA elicited a mean HR of 162 b.min-1 and a mean VO2 of 18.4 ml.kg-1.min-1 which represented 74% of HR reserve, 82% of maximal HR, and 48% of VO2 max. Average caloric expenditure was 5.7 kcal.min-1. HR values for WA were consistent with guidelines established by the American College of Sports Medicine for developing and maintaining CR fitness in healthy adults. However, the VO2 fell just below the recommended minimum threshold level. It was concluded that WA may provide an attractive alternative to traditional modes of exercise for improving CR fitness, however, HR measures may overestimate the metabolic intensity of the exercise.
将水中有氧运动（WA）期间测量的心率（HR）和摄氧量（VO2）与递增式跑步机测试中获得的最大值进行比较，以评估WA的能量需求和潜在的心肺（CR）训练效果。16名大学年龄女性作为受试者（平均±标准差=20.4±1.6岁）。WA引起的平均心率为162次·分钟-1，平均VO2为18.4毫升·千克-1·分钟-1，分别占心率储备的74%、最大心率的82%和VO2最大值的48%。平均热量消耗为5.7千卡·分钟-1。WA的心率值符合美国运动医学学院制定的关于健康成年人发展和维持CR健康的指南。然而，VO2略低于推荐的最低阈值水平。得出的结论是，WA可能是改善CR健康的传统运动方式的有吸引力的替代方法，然而，心率测量可能高估了运动的代谢强度。
