摘要：Afternoon Exercise Improves the Quality of Night Sleep: A Case Study Observed by EEG and Self-Rating Scale: SASAZAWA Yosiaki, et al. Department of Public Health. Gunma University School of Medicine -This study was designed to assess the effects of morning (10:00-12:00) and afternoon (15:00-17:00) exercise on the objective and subjective quality of sleep. The subject was a 24-year-old man in the habit of performing soccer exercises. Exercise duration was 2 hr a day with an average exercise load of 70% V0₂max, and the energy expenditure was approximately 1, 300 kcal. The polygraphic parameters of sleep were sleep stages expressed as percentages of total sleep time (%S1, %S2, %S (3+4), %SREM, %MT), time in bed, sleep time, total sleep time, sleep onset latency (SOL), waking from sleep (WAKE), sleep efficiency (SEFl), number of awakenings (NOAW), number of stage shifts, number of spindles and percentages of alpha and delta waves, all of which were assessed by an automatic computer analyzing system. The OSA questionnaire was used to assess the quality of subjective sleep. The five scales of the OSA are sleepiness, sleep maintenance, worry about sleep, integrated sleep feeling and sleep initiation. Comparisons were made between sleep parameters when the subject performed morning exercise and afternoon exercise, and in the non-exercise days by Dunnett's multiple comparison test. Sleep EEGs after afternoon exercise days showed higher %MT (p<0.05), shorter SOL (p<0.05), less WAKE (p<0.05), higher SEFI (p<0.05) and decreased NOAW (p<0.05) than those of non-exercise days. There were no significant differences between any of the sleep EEG parameters on non-exercise and morning exercise days. Only the falling asleep score of the self-rated sleep should be significantly improved by the afternoon exercise. The results suggest that afternoon exercise has a better effect on sleep than morning exercise.
