Abstract

This study compared differentiated Ratings of Perceived Exertion (RPE) for the chest (RPE-Chest) and legs (RPE-Legs) and undifferentiated ratings (RPE-Overall) between cigarette smokers (n = 10) and nonsmokers (n = 10) during graded, peak cycle exercise. Linear regression analyses expressed RPE-Chest, RPE-Leg, and RPE-Overall as a function of VO2 for smokers and nonsmokers. RPE equivalent to 50, 70, and 90% VO2 peak were compared between. Chest, Leg, and Overall RPE were similar at each % VO2 peak. In the combined smokers and nonsmokers, RPE-Chest was lower (p < .05) than the RPE-Overall at each % VO2 peak. RPE-Leg did not differ from RPE-Overall at 50% VO2 peak, but was higher (p < .05) at 70% and 90% VO2 peak. These results validate Assumption 4 for application of the Borg 15-category scale in that this assumption is also valid for differentiated RPE. Smoking did not influence the intensity of differentiated or undifferentiated RPE during graded cycle exercise.

摘要

本研究比较了吸烟组（n=10）和非吸烟组（n=10）在递增负荷、峰值自行车运动中，胸部（RPE-Chest）和腿部（RPE-Legs）的分化感知用力评分（RPE）与非分化评分（RPE-Overall）。线性回归分析将 RPE-Chest、RPE-Leg 和 RPE-Overall 表示为吸烟者和非吸烟者的 VO2 函数。比较了 RPE 相当于 50%、70%和 90%VO2 峰值的差异。在每个 %VO2 峰值时，胸、腿和整体 RPE 相似。在合并的吸烟者和非吸烟者中，RPE-Chest 在每个 %VO2 峰值时均低于 RPE-Overall（p<.05）。RPE-Leg 在 50%VO2 峰值时与 RPE-Overall 无差异，但在 70%和 90%VO2 峰值时更高（p<.05）。这些结果验证了 Borg 15 级量表应用的假设 4，即该假设也适用于分化的 RPE。吸烟对分级自行车运动中分化或非分化 RPE 的强度没有影响。
