Abstract

Background: To assess cardiorespiratory efficiency in obese adults, two exercise test treadmill protocols with 2- or 3-min stages were compared.

Methods: Thirty-six obese adult subjects were involved in this study. Sixteen men (age 51.5±10.5 years; BMI 36.7±4.8 kg/m²) and 20 women (age 42.4±12.4 years; BMI 36.5±4.7 kg/m²) performed submaximal incremental graded tests on treadmills with 2- or 3-minute stages on different days. During each testing session, heart rate (HR), oxygen uptake (VO₂ mL/min/kg), rate of perceived exertion (RPE), fat oxidation (FO) at maximal fat oxidation (MFO) and maximal fat oxidation zone (Fat_max zone) were measured.

Results: No differences were found for HR, VO₂, and RPE at MFO between the two protocols. Significant differences (2-minute vs. 3-minute) were found for FO (576.3±162.9 mg/min vs. 506.0±148.1 mg/min respectively; P<0.05) at MFO between the two protocols. No differences were found for VO₂ and HR in high and low Fat_max zone borders. Moreover, a difference was found for FO at the low and high borders.

Conclusion: Exercise intensity at which the MFO and Fat_max zone occur is not influenced by the duration of stage-to-stage increments. The two exercise testing protocols could be considered interchangeable to assess HR, VO₂, and RPE at MFO.

短期增量试验能否成为肥胖成人有效的心肺功能评估工具？两种运动测试方案的比较。

背景：为了评估肥胖成人的心肺功能，比较了两种2分钟或3分钟阶段的跑步机运动试验方案。方法：选取36例肥胖成人为研究对象。男性16例(年龄51.5±10.5岁；BMI 36.7±4.8 kg/m2)，女性20例(年龄42.4±12.4岁；BMI（36.5±4.7 kg/m2）在不同天数的跑步机上以2分钟或3分钟的阶段进行亚最大增量分级试验。在每个测试阶段，测量心率（HR）、摄氧量（VO2 mL/min/kg）、感觉运动率（RPE）、最大脂肪氧化（MFO）时的脂肪氧化（FO）和最大脂肪氧化区（Fatmax）。结果：两种方案在MFO处的HR、VO2和RPE均无差异。2分钟与3分钟的差异显著（分别为576.3±162.9 mg/min和506.0±148.1 mg/min）；P2和HR在高、低Fatmax区边界。此外，在低边界和高边界处发现了FO的差异。结论：发生MFO和Fatmax区的运动强度不受阶段间增量持续时间的影响。这两种运动测试方案可以被认为是可互换的，以评估MFO时的HR、VO2和RPE。
