运动节奏对呼吸频率的夹带的发生率通过两个频率的互相关来检测。在中度，稳态运动的自行车测力计在50转（转）/分钟，8 15名志愿者（53%）表现出夹带时，踏板速度保持恒定的节拍器，和20%的夹带时，踏板速度保持恒定的速度计。在第二组15名志愿者的70 rpm下，结果分别为60%和33%。在跑步机上进行中度稳态运动时，第三组15名志愿者中，53%的人在行走时表现出夹带，80%的人在跑步时表现出夹带。运动的节奏很可能会影响呼吸的节奏。在研究运动中的呼吸模式时，必须考虑这一控制因素。
The incidence of entrainment of breathing frequency by the rhythm of exercise was detected by a cross-correlation of the 2 frequencies. During moderate, steady-state exercise on a bicycle ergometer at 50 rev(revolutions)/min, 8 of 15 volunteers (53%) showed entrainment when pedalling speed was kept constant with a metronome, and 20% showed entrainment when pedalling speed was kept constant with a speedometer. At 70 rpm in a 2nd group of 15 volunteers, the results were 60% and 33%, respectively. During moderate, steady state exercise on a treadmill, in a 3rd group of 15 volunteers, 53% showed entrainment while walking, 80% showed entrainment while running. The rhythm of exercise is likely to affect the rhythm of breathing. This controlling factor must be considered during studies of breathing pattern in exercise.
