The purpose of this study was to compare the energy expenditures (EE) of a single sit-to-stand (STS) movements with slow and normal speeds using a multi-stage exercise test. Twelve young males, aged 21⁻27 years (age, 23.0 ± 1.7 years; height, 171.2 ± 6.1 cm; weight, 64.3 ± 5.6 kg), performed repeated 3-s stand-up and 3-s sit-down (slow) or 1-s stand-up and 1-s sit-down (normal) movement on two different days with random order. All the participants completed multi-stage tests at different STS frequencies per minute. The slope and intercept of the linear regression relationship between the EE (kcal/min) and the STS frequency were obtained, and the slope of the regression was quantified as the EE of an STS. The metabolic equivalents (METs) of the STS-slow was 4.5 METs for the frequency of 10 times/min (in total 1 min), and the net EE was 5.00 ± 1.2 kcal/min. The net EE of the STS-slow was 0.37 ± 0.12 kcal, which was significantly greater than that during the STS-normal (0.26 ± 0.06 kcal). The difference between the EEs of the STS-slow and STS-normal was significantly greater in taller and heavier subjects. We concluded that the intensity of STS-slow movement is moderate, and the EE during an STS-slow (0.37 ± 0.12 kcal) is higher than that during an STS-normal (0.26 ± 0.06 kcal). Our study results will help exercise and/or health professionals prescribe physical activity programs using STS movement for healthy young population groups.
本研究旨在比较使用多阶段运动测试时，以慢速和正常速度进行单次坐站（STS）运动的能量消耗（EE）。12 名年轻男性，年龄 21-27 岁（年龄，23.0 ± 1.7 岁；身高，171.2 ± 6.1cm；体重，64.3 ± 5.6kg），在两天内以随机顺序重复进行 3 秒站立和 3 秒坐下（慢）或 1 秒站立和 1 秒坐下（正常）运动。所有参与者均在不同的 STS 频率下完成了多阶段测试。获得 EE（千卡/分钟）与 STS 频率之间的线性回归关系的斜率和截距，并且回归的斜率被量化为 STS 的 EE。STS-慢的代谢当量（METs）为 10 次/分钟（总计 1 分钟）的频率为 4.5 METs，净 EE 为 5.00 ± 1.2 千卡/分钟。STS-慢的净 EE 为 0.37 ± 0.12 千卡，明显大于 STS-正常（0.26 ± 0.06 千卡）。STS-慢和 STS-正常的 EE 之间的差异在更高和更重的受试者中明显更大。我们得出结论，STS-慢运动的强度适中，STS-慢（0.37 ± 0.12 千卡）期间的 EE 高于 STS-正常（0.26 ± 0.06 千卡）。我们的研究结果将有助于运动和/或健康专业人员为健康的年轻人群组使用 STS 运动来制定体育活动计划。
