This study examined the effects of low-intensity exercise in the morning on exercise performance in the afternoon. Fifteen healthy men were exposed to two measurement conditions: 30 min of bicycle exercise at 40% of maximum oxygen consumption (morning exercise) or rest in the sitting posture (control) at 8:30 AM. Physiological parameters were measured at 4:00 PM with the participant at rest in the supine position. Physical fitness tests and anaerobic power tests began at 4:30 PM. The two conditions demonstrated no significant difference in heart rate, systolic or diastolic blood pressure, double product, total power of R-R interval variability, ln HF (index of cardiovascular parasympathetic nervous system activity), or oral temperature. Morning exercise was associated with significantly better 20-m shuttle run, standing long jump, and sit-and-reach performance compared to the control condition. No significant differences in other physical fitness tests were observed. Thus, participants had significantly higher total physical fitness test scores and significantly greater maximum anaerobic power under the morning exercise condition. Our results indicate that low-intensity exercise in the morning might enhance afternoon exercise performance and may be considered an effective conditioning method on the day of a sporting event.
