The aim of this study was to compare the effects of 11 weeks of low-volume resistance training (LVRT) and high-volume resistance training (HVRT) on muscle strength, muscle thickness (MT), and postprandial lipaemia (PPL) in postmenopausal women. Thirty-six healthy and untrained postmenopausal women (age, 58.9 ± 5.8 years; 68.6 ± 10.3 kg; and BMI, 26.9 ± 4.8 kg · m(-2)) participated in resistance training 3× per week for 11 weeks (HVRT = 12; LVRT = 13; and control group = 11). Biochemical variables, both pretraining and post-training, were evaluated 16 h after the administration of an oral fat tolerance test (OFTT) and metabolic variable during [energy expenditure (EE)] and after training session [excess postexercise oxygen consumption (EPOC)]. Muscle strength (1 RM) and MT were also calculated, and no significant differences were observed between the groups for PPL (mmol · L(-1) per 5 h) as measured by glucose, high-density lipoprotein, low-density lipoprotein, and total cholesterol. EE total (EE + EPOC; 6.12 ± 1.21 MJ vs. 2.26 ± 0.85 MJ), resting fat oxidation (5.52 ± 1.69 g · h(-1) vs. 4.11 ± 1.12 g · h(-1)); MT (vastus medialis, 21.4 ± 1.8 mm vs. 18.4 ± 1.2 mm and vastus lateralis 22.3 ± 1.2 mm vs. 20.8 ± 1.3 mm); triacylglycerol (TAG) 0, 1, 2, 4; and 5 h after OFTT, TAG area under the curve (AUC) (5.79 ± 0.42 vs. 7.78 ± 0.68), and incremental AUC (-46.21 ± 14.42% vs. 7.78 ± 4.68%) were all significantly different post-training for HVRT versus LVRT, respectively (P < 0.05). The results of this investigation suggest that HVRT reduces PPL in postmenopausal women.
本研究的目的是比较11周低容量抗阻训练（LVRT）和高容量抗阻训练（HVRT）对绝经后女性肌肉力量、肌肉厚度（MT）和餐后血脂异常（PPL）的影响。36名健康且未经训练的绝经后女性（年龄58.9±5.8岁；体重68.6±10.3千克；体重指数26.9±4.8千克·米⁻²）每周进行3次抗阻训练，共11周（HVRT组=12人；LVRT组=13人；对照组=11人）。在口服脂肪耐量试验（OFTT）给药16小时后评估训练前和训练后的生化变量，以及训练期间的代谢变量[能量消耗（EE）]和训练后[运动后过量氧耗（EPOC）]。还计算了肌肉力量（1RM）和MT，通过葡萄糖、高密度脂蛋白、低密度脂蛋白和总胆固醇测量的PPL（每5小时毫摩尔·升⁻¹）在各组之间未观察到显著差异。EE总量（EE+EPOC；6.12±1.21兆焦对2.26±0.85兆焦）、静息脂肪氧化（5.52±1.69克·小时⁻¹对4.11±1.12克·小时⁻¹）；MT（股内侧肌，21.4±1.8毫米对18.4±1.2毫米，股外侧肌22.3±1.2毫米对20.8±1.3毫米）；OFTT后0、1、2、4和5小时的三酰甘油（TAG）、TAG曲线下面积（AUC）（5.79±0.42对7.78±0.68）以及增量AUC（-46.21±14.42%对7.78±4.68%）在训练后HVRT组和LVRT组之间均有显著差异（P<0.05）。本研究结果表明，HVRT可降低绝经后女性的PPL。
