Effects of slow tempo exercise on respiration, heart rate, and mood state.

The purpose of this study was to investigate psychophysiologic responses to slow movement tempo exercise in three experiments. Exps. 1 and 2 were designed to compare slow with preferred movement tempos chosen freely by the subjects. The task movements in Exp. 1 were repetitive Arm Swinging, Stepping, and Body Swaying, performed by 14 female undergraduate students, while in Exp. 2, Body Swaying and Arm Winding were performed by 10 female undergraduate students and 13 boys and girls junior high school students. Respiration, heart rate, and scores on the State-Trait Anxiety Inventory were measured. Analysis showed respiration rates were lower during slow tempo conditions than preferred conditions. Exp. 3 was designed to compare very slow with slow movement tempos, using a Tai Chi-type of movement performed by 6 female undergraduate students. The subjects were required to synchronize the task movement with auditory stimuli, during which respiration and heart rate were measured, and a UWIST Mood-Adjective Checklist was utilized. Under the very slow movement conditions, Energetic Arousal scores were lower than those for the slow movement and the variation of respiration between rest and task conditions corresponded inversely with the Tense Arousal scores. Together, our results suggest that slow tempo exercise does not increase physiological or psychological arousal.
