Abstract

PURPOSE

To investigate the maximal physiological responses between aquatic and land-based graded exercise tests in overweight women.

METHODS

Twenty healthy, overweight (body mass index (BMI) > or = 25 kg.m(-2)), Caucasian women (mean +/- SD; age 48 +/- 7 yr, BMI 30 +/- 4 kg.m(-2)) completed a deep water running (DWR) and treadmill walking (TMW) graded exercise test. Maximal responses during the DWR and TMW graded exercise tests were compared using paired t-tests. Comparisons were made in the incidence of achievement of maximal oxygen consumption (VO2max) criteria between DWR and TMW protocols. Criteria were a plateau in VO2 (change < 2.1 mL.kg.min(-1)), heart rate (HR) equal to or above the age-adjusted maximum, and respiratory exchange ratio (RER) > or = 1.15.

RESULTS

Maximal responses for VO2max (22.5 +/- 4.86 vs 27.7 +/- 4.73 mL.kg.min(-1)), HRmax (159 +/- 16 vs 170 +/- 12 bpm), and RER (1.03 +/- 0.06 vs 1.10 +/- 0.06) were significantly lower (P < 0.01) for the DWR test compared with the TMW test, respectively. Achievement of various VO2max criteria was demonstrated more consistently during the TMW test than the DWR test.

CONCLUSION

Maximal physiological responses of overweight women to DWR and TMW are significantly different but are comparable with other populations. As the maximal responses for DWR compared with TMW differ, the use of land-based criteria for VO2max is not recommended for a graded DWR exercise test.

摘要

目的

研究超重女性在水上和陆地分级运动测试中的最大生理反应。

方法

20名健康的超重（体重指数（BMI）≥25 kg·m⁻²）白种女性（平均±标准差；年龄48±7岁，BMI 30±4 kg·m⁻²）完成了深水跑步（DWR）和跑步机行走（TMW）分级运动测试。使用配对t检验比较DWR和TMW分级运动测试期间的最大反应。比较了DWR和TMW方案中达到最大耗氧量（VO₂max）标准的发生率。标准为VO₂达到平台期（变化<2.1 mL·kg·min⁻¹）、心率（HR）等于或高于年龄校正最大值，以及呼吸交换率（RER）≥1.15。

结果

与TMW测试相比，DWR测试的VO₂max最大反应（22.5±4.86 vs 27.7±4.73 mL·kg·min⁻¹）、HRmax（159±16 vs 170±12次/分钟）和RER（1.03±0.06 vs 1.10±0.06）分别显著降低（P<0.01）。与DWR测试相比，TMW测试期间更一致地证明达到了各种VO₂max标准。
