本研究首次将博格的心理物理方程应用于测量举重机力量训练的反应。博格量表的理论结构进行了评估，在年轻人和老年人，以估计适当的负荷和重复次数，以满足推荐的实践指南。年轻组（YG; 20名男性，20名女性;年龄19-38岁）和老年组（OG; 13名男性，13名女性;年龄50-75岁）参与3个实验。实验1：YG在肱三头肌-肘关节伸展和膝关节伸展过程中重复2次递增负荷，达到博格CR 10量表上的7级。实验2：YG（n = 16）然后在实验1的负荷下重复12次，得出CR 10评分1.5、3.0和5.0。实验3：OG在15次重复的最大（RM）负荷下进行15次重复的“lat-pull”和腿部推举。在实验2和3中，每2次重复测量CR 10或博格RPE。实验1揭示了典型的心理物理反应增长指数在1.1和1.8之间，手臂比腿（p < 0.001）和女性（p < 0.001）更大。1 RM的理论估计值来自于引发CR 10评级为1.5、3和5的权重的增长曲线。CR 10评分为3至6分，在40%-70%的1 RM估计范围内。实验2和3显示，对于恒定负荷运动“随时间推移”（12和15次重复），从最初的CR 10等级4到6，每3到4次重复线性增加1个标度点。总之，已使用博格方程设定%1 RM的理论估计值。与当前实践指南相关的是，能够根据执行推荐的重复次数（e.例如，在一个实施例中，如果在2次重复后CR 10等级>6，则重量可能太重而无法完成12至15次重复）。
This study is the first to apply Borg's psychophysical equation to measuring responses to strength training with weights machines. Theoretical constructs of Borg's scales were assessed in younger and older adults to estimate the appropriate load and number of repetitions required to meet recommended practice guidelines. A younger group (YG; 20 males, 20 females; aged 19-38 years) and older group (OG; 13 males, 13 females; aged 50-75 years) participated in 3 experiments. Experiment 1: YG performed 2-repetitions of incremented loads during triceps-elbow extensions and knee extensions to level 7 on Borg's CR10 Scale. Experiment 2: YG (n = 16) then performed 12-repetitions at the loads from experiement 1 that elicited CR10 ratings 1.5, 3.0, and 5.0. Experiment 3: OG performed 15-repetitions of "lat-pull" and leg press at 15-repetition maximum (RM) load. In experiments 2 and 3, CR10 or Borg RPE were measured every 2 repetitions. Experiment 1 revealed classic psychophysical response growth exponents between 1.1 and 1.8, which were greater in arms than legs (p < 0.001) and in females (p < 0.001). Theoretical estimates of 1RM were derived from the growth curves for the weights eliciting CR10 ratings of 1.5, 3, and 5. CR10 ratings of 3 to 6 fell within estimates of 40%-70% 1RM. Experiments 2 and 3 revealed, for constant load exercise " over time" (12 and 15 repetitions) from an initial CR10 rating of 4 to 6, a linear increase of 1 scale point for every 3 to 4 repetitions. In conclusion, Borg's equation has been used to set theoretical estimates of a %1RM. Relevant to current practice guidelines was the ability to set appropriate loads in relation to performing recommended numbers of repetitions (e. g., if the CR10 rating is >6 after 2 repetitions, the weight is likely be too heavy to complete 12 to 15 repetitions).
