The purpose of this study was to quantify the metabolic equivalents (METs) of resistance exercise in obese patients with type 2 diabetes (T2DM) and healthy young subjects and to evaluate whether there were differences between sessions executed at low- versus high-intensity resistance exercise. Twenty obese patients with T2DM (62.9±6.1 years) and 22 young subjects (22.6±1.9 years) performed two training sessions: one at vigorous intensity (80% of 1-repetition maximum (1RM)) and one at moderate intensity (60% of 1RM). Both groups carried out three strength exercises with a 2-day recovery between sessions. Oxygen consumption was continuously measured 15 min before, during and after each training session. Obese T2DM patients showed lower METs values compared with young healthy participants at the baseline phase (F= 2043.86; P<0.01), during training (F=1140.59; P<0.01) and in the post-exercise phase (F=1012.71; P<0.01). No effects were detected in the group x intensity analysis of covariance. In this study, at both light-moderate and vigorous resistance exercise intensities, the METs value that best represented both sessions was 3 METs for the obese elderly T2DM patients and 5 METs for young subjects.
本研究的目的是量化2型糖尿病(T2DM)肥胖患者和健康年轻受试者进行抗阻运动时的代谢当量(METs),并评估低强度与高强度抗阻运动训练之间是否存在差异。20名T2DM肥胖患者(62.9±6.1岁)和22名年轻受试者(22.6±1.9岁)进行了两次训练:一次为高强度(1次重复最大值(1RM)的80%),一次为中等强度(1RM的60%)。两组均进行三项力量训练,训练之间间隔2天恢复。在每次训练前、训练期间和训练后15分钟连续测量耗氧量。在基线期(F=2043.86;P<0.01)、训练期间(F=1140.59;P<0.01)和运动后阶段(F=1012.71;P<0.01),肥胖T2DM患者的METs值均低于年轻健康参与者。在组×强度协方差分析中未检测到效应。在本研究中,对于肥胖老年T2DM患者,在轻-中等强度和高强度抗阻运动强度下,最能代表两次训练的METs值均为3 METs,而年轻受试者为5 METs。
