在三名健康男性中，以相同的平均能量输出进行连续和间歇运动的成对模式，使用线性分级量表测量感知运动。工作时间为10秒的间歇运动，交替进行30秒的无负荷蹬车恢复期，与工作时间为30秒或120秒的间歇运动相比，其感知的劳累程度较低。在平均功率输出相同的情况下，间歇运动的感知劳累、摄氧量、通气、心率和血乳酸浓度均显著高于连续运动。尽管腿部承受的机械压力大不相同，但这两种运动形式的感知强度与生理变量之间的关系是相同的。因此，在研究的运动强度范围内，机械因素被认为对感知运动的贡献相对不重要。-感知到的运动强度与测量到的生理变量之间的高度相关性表明，运动强度分级在实地研究中有更广泛的应用。
Perceived exertion was measured using a linear grading scale, in three healthy males performing paired patterns of continuous and intermittent exercise with the same average power output. Intermittent exercise with work periods of 10 sec. alternating with recovery periods of loadless pedalling for 30 sec. was associated with lower perceived exertion grades than when work periods were 30 or 120 sec. Perceived exertion, oxygen intake, ventilation, heart rate, and blood lactate concentration were all significantly higher for intermittent exercise than for continuous exercise with the same average power output. The relationships between perceived exertion and the physiological variables was the same for the two forms of exercise despite widely different mechanical stresses on the legs. Mechanical factors were therefore thought to make a relatively unimportant contribution to perceived exertion over the range of exercise intensities studied.—The high degree of correlation between perceived exertion and the measured physiological variables suggests a wider use of exertion grading in field studies.
