The purpose of this study was to assess the lifting performance of boys (N = 12; age 11.3 +/- 0.8 yr), teens (N = 13; age 13.6 +/- 0.6 yr), and men (N = 17; age 21.4 +/- 2.1 yr) to various rest interval (RI) lengths on the bench press exercise. Each subject performed 3 sets with a 10 repetition maximum load and a 1, 2, and 3 min RI between sets. Significant differences in lifting performance between age groups were observed within each RI for selected sets with boys and teens performing significantly more total repetitions than adults following protocols with 1 min (27.9 +/- 3.1, 26.9 +/- 3.9, and 18.2 +/- 4.1, respectively), 2 min (29.6 +/- 1.0, 27.8 +/- 3.5, and 21.4 +/- .1, respectively) and 3 min (30.0 +/- 0.0, 28.8 +/- 2.4, and 23.9 +/- 5.3, respectively) RIs. Significant differences in average velocity and average power between age groups were also observed. These findings indicate that boys and teens are better able to maintain muscle performance during intermittent moderate-intensity resistance exercise as compared with men.
本研究的目的是评估男孩（N = 12；年龄11.3±0.8岁）、青少年（N = 13；年龄13.6±0.6岁）和男性（N = 17；年龄21.4±2.1岁）在卧推练习中对不同休息间隔（RI）时长的举重表现。每位受试者以10次最大重复负荷进行3组练习，组间休息间隔为1、2和3分钟。在每个RI下，选定组的年龄组间举重表现存在显著差异，在1分钟（分别为27.9±3.1、26.9±3.9和18.2±4.1）、2分钟（分别为29.6±1.0、27.8±3.5和21.4±0.1）和3分钟（分别为30.0±0.0、28.8±2.4和23.9±5.3）RI方案下，男孩和青少年的总重复次数显著多于成年人。年龄组间的平均速度和平均功率也存在显著差异。这些发现表明，与男性相比，男孩和青少年在间歇性中等强度抗阻运动中更能保持肌肉表现。
