The purpose of this study was to compare the physiologic effects of a program of combined running and weight training (RUN-CWT) with a program of circuit weight training (CWT). Thirty-six females (X age = 35.7 yr) and 41 males (X age = 36.1 yr) were randomly assigned to RUN-CWT, CWT, and control groups. The training groups participated in 12-wk programs, 3 d . wk-1. Three circuits of 10 weight-training exercises were completed with 12-15 repetitions performed in 30 s at 40% of one-repetition maximum at each station. The 30-min RUN-CWT program included 30 s of running on an indoor track following each CWT station, whereas the 22.5 min CWT program included a 15-s rest period between stations. The RUN-CWT groups had a significant (+ 17%) increase in VO2max (females 30.5-35.7 ml . kg-1 . min-1 and males 39.7-46.3 ml . kg-1 . min-1) and strength (females + 24% and males +21%), and a significant decrease in body fat percentage (females -3.2% and males -4.1%). The CWT groups also increased significantly in VO2max (+12%) and strength (+17%) and decreased in body fat (-3.0%). The controls did not change significantly in any variable. Statistically, one training program was not shown to be superior to the other; thus, both programs of RUN-CWT and CWT were effective in improving measures of physical fitness.
本研究的目的是比较跑步与负重训练相结合的方案（RUN-CWT）和循环负重训练方案（CWT）的生理效应。36名女性（平均年龄 = 35.7岁）和41名男性（平均年龄 = 36.1岁）被随机分配到RUN-CWT组、CWT组和对照组。训练组参加为期12周的训练方案，每周训练3天。每个训练站进行3组，每组10个负重训练动作，每组重复12 - 15次，在30秒内完成，强度为一次最大重复量的40%。30分钟的RUN-CWT方案在每个CWT训练站之后包括30秒的室内跑道跑步，而22.5分钟的CWT方案在训练站之间包括15秒的休息时间。RUN-CWT组的最大摄氧量显著增加（+17%）（女性从30.5毫升·千克⁻¹·分钟⁻¹增加到35.7毫升·千克⁻¹·分钟⁻¹，男性从39.7毫升·千克⁻¹·分钟⁻¹增加到46.3毫升·千克⁻¹·分钟⁻¹）以及力量增加（女性 +24%，男性 +21%），体脂百分比显著降低（女性 -3.2%，男性 -4.1%）。CWT组的最大摄氧量也显著增加（+12%）和力量增加（+17%），体脂降低（-3.0%）。对照组在任何变量上均无显著变化。从统计学角度来看，未显示一种训练方案优于另一种；因此，RUN-CWT和CWT这两种方案在改善身体素质指标方面均有效。
