本研究检验了使用三个标准（年龄预测的最大心率 [HRmax]、呼吸交换比 [RER>1.10] 和摄氧量平台 [Vo2] 来测量绝经后女性最大耗氧量 (Vo2max) 的适用性。108 名绝经后（60 ± 6 岁）、超重和肥胖（体重指数 [BMI] = 33 ± 4） kg/m2）、久坐不动（Vo2max = 19 ± 3 ml/kg/min）的女性接受了一次运动测试（Bruce 方案），其中 71 名女性接受了第二次测试（修改后的 Balke 方案）。在测试 1 中，69 名（64%）女性达到了年龄预测的 HRmax，61 名（57%）达到了 RER>1.10，16 名（15%）达到了 Vo2 平台（<2）。达到年龄预测 HRmax 且 RER 至少为 1.10 的女性比未达到这些标准的女性具有更高的峰值 Vo2 (p<0.01)。在测试 1 期间达到和未达到稳定水平的女性获得的最高 V02 没有差异。平均而言，静息 HR、HRmax 和 RER 相似。第二次测试中的 Vo2 较高（p<0.01），但在两项测试中至少达到三项标准中的两项的女性中，Vo2max 没有差异（n = 24；测试 1，19.4 ± 3.4；测试 2：19.8 ± 3.7 ml/kg/min；p= NS）。此外，在第二次测试中达到稳定水平的 14 名女性中，两次运动测试中的 Vo2max 相似。第一次测试时未达到稳定水平（19.2 ± 3.3 vs. 19.6 ± 4.2 ml/kg/min；p= NS）。我们得出结论，Vo2 达到稳定水平并不是超重、肥胖、久坐、绝经后女性有效测量 Vo2max 的必要标准。
This study examines the applicability of using three standard criteria (age-predicted maximal heart rate [HRmax], respiratory exchange ratio [RER>1.10], and plateau in oxygen uptake [Vo2] for the measurement of maximal oxygen consumption (Vo2max) in postmenopausal women. One hundred eight postmenopausal (60 ± 6 years), overweight and obese (body mass index [BMI] = 33 ± 4 kg/m2), sedentary (Vo2max = 19 ± 3 ml/kg/min) women underwent one exercise test (Bruce protocol), and 71 of these women underwent a second test (modified Balke protocol). On test 1, 69 (64%) women achieved age-predicted HRmax, 61 (57%) reached an RER>1.10, and 16 (15%) achieved a plateau in Vo2(<2 ml/kg/min change). Women who reached age-predicted HRmax and reached an RER of at least 1.10 had a higher peak Vo2(p<0.01) than women who did not meet these criteria. There was no difference in the highest V02 obtained between women who did and did not achieve a plateau in Vo2during test 1 (p= 0.55). Resting HR, HRmax, and RER were similar between the two tests. On average, peak Vo2was higher on the second test (p<0.01). However, Vo2max was not different between exercise tests in women who achieved at least two of the three criteria on both tests (n= 24; test 1, 19.4 ± 3.4; test 2: 19.8 ± 3.7 ml/kg/min;p= NS). In addition, Vo2max was similar between the two exercise tests in 14 women who reached a plateau on the second test but did not reach a plateau on the first test (19.2 ± 3.3 vs. 19.6 ± 4.2 ml/kg/min;p= NS). We conclude that achievement of a plateau in Vo2is not a necessary criterion for a valid measurement of Vo2max in overweight and obese, sedentary, postmenopausal women.
