Nine males (age 24.7 ± 2.1 years, height 175.3 ± 5.5 cm, body mass 80.8 ± 7.2 kg, power clean 1-RM 97.1 ± 6.36 kg, squat 1-RM = 138.3 ± 20.9 kg) participated in this study. On day 1, the participants performed a one-repetition maximum (1-RM) in the power clean and the squat. On days 2, 3, and 4, participants performed the power clean, squat or jump squat. Loading for the power clean ranged from 30% to 90% of the participant's power clean 1-RM and loading for the squat and jump squat ranged from 0% to 90% of the participant's squat 1-RM, all at 10% increments. Peak force, velocity, and power were calculated for the bar, body, and system (bar + body) for all power clean, squat, and jump squat trials. Results indicate that peak power for the bar, body, and system is differentially affected by load and movement pattern. When using the power clean, squat or jump squat for training, the optimal load in each exercise may vary. Throwing athletes or weightlifters may be most concerned with bar power, but jumpers or sprinters may be more concerned with body or system power. Thus, the exercise type and load vary according to the desired stimulus.
九名男性（年龄 24.7 ± 2.1 岁，身高 175.3 ± 5.5cm，体重 80.8 ± 7.2kg，硬拉 1RM 97.1 ± 6.36kg，深蹲 1RM = 138.3 ± 20.9kg）参与了这项研究。在第 1 天，参与者进行了一次硬拉和深蹲的最大重复次数（1-RM）测试。在第 2、3 和 4 天，参与者进行了硬拉、深蹲或跳蹲练习。硬拉的负荷范围为参与者硬拉 1-RM 的 30%至 90%，深蹲和跳蹲的负荷范围为参与者深蹲 1-RM 的 0%至 90%，均以 10%的增量递增。对所有硬拉、深蹲和跳蹲试验的杠铃、身体和系统（杠铃+身体）计算了峰值力量、速度和功率。结果表明，杠铃、身体和系统的峰值功率受到负荷和运动模式的不同影响。在使用硬拉、深蹲或跳蹲进行训练时，每个练习的最佳负荷可能会有所不同。投掷运动员或举重运动员可能更关心杠铃的功率，但跳跃运动员或短跑运动员可能更关心身体或系统的功率。因此，根据所需的刺激，练习类型和负荷会有所不同。
