研究了短期阻力训练对久坐不动的生活方式和代谢综合征相关的运动能力和健康变量的影响。抵抗力训练可能会改变一些与健康有关的、生理的和表现的变量。因此，阻力训练可以作为一种有价值的工具来改善久坐不动的生活方式的影响，包括与代谢综合征相关的影响。19名以前久坐的受试者(10名代谢综合征，9名非代谢综合征)接受了8周的有监督的阻力训练。最大力量的测量是使用等长的大腿中段拉力和由此产生的力-时间曲线。垂直跳跃高度和功率用测力板测量。用肌肉活检和标准分析技术检测肌肉横截面积(CSA)和类型。使用ParvoMedics 2400代谢系统在自行车测功仪上测量有氧功率。耐力是在自行车测功器上测量到力竭的时间。训练后，代谢综合征组和非代谢综合征组(男性和女性受试者)的最大等长力量、跳跃高度、跳跃功率和V̇O2峰值都增加了约10%(或更多)。经过8周的训练，体重没有统计学上的变化，但代谢综合征受试者和女性的体脂百分比下降，所有组的瘦体质量都增加了(p<；0.05)。纤维类型变化不大。与女性相比，男性的CSA更大，而且随着时间的推移，有一种特定纤维肥大的趋势。总而言之，八周的半块自由重量阻力训练改善了几个表现变量和一些与代谢综合征相关的心血管因素。
The effects of short-term resistance training on performance and health variables associated with prolonged sedentary lifestyle and metabolic syndrome were investigated. Resistance training may alter a number of health-related, physiological and performance variables. As a result, resistance training can be used as a valuable tool in ameliorating the effects of a sedentary lifestyle including those associated with metabolic syndrome. Nineteen previously sedentary subjects (10 metabolic syndrome, 9 non-metabolic syndrome) underwent 8 weeks of supervised resistance training. Maximum strength was measured using an isometric mid-thigh pull and resulting force-time curve. Vertical jump height and power were measured using a force plate. Muscle cross-sectional area (CSA) and type were examined using muscle biopsy and standard analysis techniques. Aerobic power was measured on a cycle ergometer using a ParvoMedics 2400 Metabolic system. Endurance was measured as time to exhaustion on a cycle ergometer. After training, maximum isometric strength, jump height, jump power and V̇O2 peak increased by approximately 10% (or more) in both the metabolic and non-metabolic syndrome groups (both male and female subjects). Over 8 weeks of training, body mass did not change statistically, but percent body fat decreased in subjects with the metabolic syndrome and in females, and lean body mass increased in all groups (p<0.05). Few alterations were noted in fiber type. Males had larger CSA’s compared to females and there was a fiber-specific trend toward hypertrophy over time. In summary eight weeks of semi-block free-weight resistance training improved several performance variables and some cardiovascular factors associated with metabolic syndrome.
