The aim was to analyze the relationship between the perceived exertion (PE) and different loads in strength exercises (SEs), in sedentary, active, and trained adult subjects. Thirty young men (18-34 years) were divided into 3 groups (experimental group [EG]): sedentary EG (SEG), physically active group (PAG), and the strength trained group (STG). Maximum strength was established using the 1 repetition maximum test (1RM). Using series of 12 repetitions, different loads were applied until the 4 ratings of PE (RPEs) (11, 13, 15, and 17) from 15 category Borg Perceived Exertion Scale (RPE 6-20). The pace of the repetitions and the intervals between the sets were controlled, the loads were blind, the order of the RPE randomized, whereas the PE was localized and determined after completion of the series. Strength correlations between the RPE and the %1RM, according to the EGs and SEs (0.826-0.922, p < 0.001), were observed. Similar behavior was seen in the SEs. Higher loads are related to higher RPEs and are differentiated between the EGs. The STG used higher %1RM when compared to the SEG, whereas the PAG, displayed an intermediary behavior in relation to the other groups. The use of PE represents a reliable instrument for the measurement of intensity in strength training.
目的在于分析感知用力（PE）与不同负荷在力量训练中的关系，涉及久坐、活跃和训练有素的成年受试者。30 名年轻男性（18-34 岁）被分为 3 组（实验组 [EG]）：久坐 EG（SEG）、活跃组（PAG）和力量训练组（STG）。最大力量使用 1 次最大重复测试（1RM）确定。使用 12 次重复的系列，施加不同的负荷，直到达到 15 级 Borg 感知用力量表（RPE 6-20）的 4 个 PE 等级（11、13、15 和 17）。重复的节奏和组间间隔受到控制，负荷是盲测的，RPE 等级的顺序是随机的，而 PE 是在完成系列后定位和确定的。根据 EG 和 SE（0.826-0.922，p<0.001），观察到 RPE 与 %1RM 之间的力量相关性。在 SE 中也观察到了类似的行为。更高的负荷与更高的 RPE 相关，并在 EG 之间进行区分。与 SEG 相比，STG 使用了更高的 %1RM，而 PAG 与其他组相比表现出中间行为。PE 的使用是力量训练中测量强度的可靠工具。
