文题释义:
最大脂肪氧化强度:在中低强度范围,人体脂肪氧化量随着运动强度的增加逐渐增加,在运动强度与脂肪氧化量相关之间存在诱导脂肪氧化量出现最大值的运动强度,称为最大脂肪氧化强度。
代谢当量:是以安静且坐位时的能量消耗为基础,表达各种活动时相对能量代谢水平的常用指标。可以用来评估心肺功能。
摘要
背景:
按单位时间内脂肪氧化量最大值对应的运动强度运动可达到理想的减肥效果。近年来大多是采用递增负荷方案测定受试者的最大脂肪氧化强度,然而无氧阈是有氧代谢为主转向无氧代谢为主的拐点,研究证实无氧阈水平与最大脂肪氧化强度有较强的相关性,但以个体无氧阈水平为恒定负荷强度是否也可以准确的测定最大脂肪氧化强度,相关研究较少。
目的:研究年轻女性递增负荷和恒定负荷方案下的最大脂肪氧化强度,探讨两种测试方案下最大脂肪氧化强度的变化。
方法:对66名年轻女性分别进行递增负荷和恒定负荷方案跑台运动测试,采集运动过程中人体的气体代谢指标数据,计算脂肪氧化量,测定出两种方案下的最大脂肪氧化强度。
结果与结论:跑步运动测试,以个体无氧阈水平为恒定负荷方案强度测得的最大脂肪强度值较递增负荷方案测试值高,但差异不显著(P > 0.05)。递增负荷方案测得最大脂肪氧化强度是(54.60±9.02)%VO2max,(66.93±6.63)%HRmax,以无氧阈水平为恒定负荷方案的最大脂肪氧化强度为(56.71±6.65)%VO2max,(66.53±8.27)%HRmax;此外,恒定负荷方案最大脂肪氧化强度对应的呼吸交换率、运动速度相对较高(P < 0.01),测得最大脂肪氧化强度所需的时间较短,脂肪供能比例却较低(P < 0.01)。结果说明,从运动强度和测试需要的时间考虑,建议选择以个体无氧阈水平为恒定负荷方案强度进行最大脂肪氧化强度测试,尤其是年迈体弱、肥胖或不能长时间进行大强度运动人群。

Abstract:

BACKGROUND: The exercise intensity corresponding to the maximal amount of fat oxidation per unit time contributes to losing weight. In recent years, the maximum fat oxidation intensity of the subjects is determined by the incremental load program. However, the anaerobic threshold is the turning point of aerobic metabolism to anaerobic metabolism, which has been shown to be related to the maximum fat oxidation. Whether individualized anaerobic threshold level can accurately detect the maximum fat oxidation is unknown.
OBJECTIVE: To study the maximal fat oxidation under increasing load scheme and constant load scheme, and to explore the changes of maximal fat oxidation under the two schemes.
METHODS: Sixty-six young females underwent treadmill exercise with increasing and constant load schemes, respectively. Gas metabolism indexes during exercise were collected to calculate the fat oxidation and the maximal fat oxidation under the two regimens.
RESULTS AND CONCLUSION: The constant load scheme showed a slightly, but not significantly, higher maximum fat oxidation intensity compared with increasing load scheme (P > 0.05). Under increasing load, the maximal fat oxidation intensity was (54.60±9.02)%VO2max and (66.93±6.63)%HRmax, and under constant load, it was (56.71±6.65)%VO2max and (66.53±8.27)%HRmax. Moreover, under constant load, the respiratory exchange ratio and movement velocity corresponding to the maximum fat oxidative intensity were high (P < 0.01), the test time was short and the ratio of energy supplied by fats was low (P < 0.01). Considering the intensity of exercise and time consumption, it is recommended to detect the maximal fat oxidation intensity based on the individual anaerobic threshold level under constant load, especially the older adults who are weak, obese or cannot exercise for a long time.
