To examine the heart rate-perceived exertion relationship between maximal exercise testing and home-based aerobic training in neuromuscular diseases.
Multicentre randomized controlled trial, intervention group data.
Individuals with Charcot-Marie-Tooth disease (n = 17), post-polio syndrome (n = 7) or other neuromuscular diseases (n = 6).
Participants followed a 4-month, homebased aerobic training programme guided by heart rate. Heart rate and ratings of perceived exertion (6-20 Borg Scale) were assessed for each minute during a maximal exercise test, and at the end of each exercise interval and recovery period during training. Heart rate and corresponding ratings of perceived exertion values of individual participants during training were visualized using plots, together with the exercise testing linear regression line between heart rate and ratings of perceived exertion.
High correlation coefficients (i.e. > 0.70) were found between heart rate and ratings of perceived exertion, in all participants during testing (n = 30), and in 57% of the participants during training. Based on the plots the following distribution was found; participants reporting lower (n = 12), similar (n = 10), or higher (n = 8) ratings of perceived exertion values for corresponding heart rates during training compared with testing.
Most participants had a different perception of effort for corresponding heart rates during training in comparison with exercise testing. Healthcare professionals should be aware that this may imply under- and over-training.
研究神经肌肉疾病患者在最大运动测试和家庭有氧运动训练中心率与感知用力的关系。
多中心随机对照试验，干预组数据。
Charcot-Marie-Tooth 病（n=17）、脊髓灰质炎后综合征（n=7）或其他神经肌肉疾病患者（n=6）。
参与者接受为期 4 个月的家庭有氧运动训练计划，该计划由心率指导。在最大运动测试的每一分钟、训练期间的每个运动间隔和恢复期间评估心率和感知用力（6-20 Borg 量表）的评分。使用图表可视化训练期间个体参与者的心率和相应的感知用力值，以及心率和感知用力之间的测试线性回归线。
在所有参与者的测试（n=30）和 57%的参与者的训练中，心率和感知用力之间的相关系数（即>0.70）均较高。基于图表，发现以下分布；与测试相比，训练期间报告较低（n=12）、相似（n=10）或较高（n=8）感知用力值的参与者对应心率的分布。
与运动测试相比，大多数参与者在训练中心率与感知用力的关系上有不同的感知。医疗保健专业人员应该意识到，这可能意味着训练不足和过度训练。
