Effects of regular physical activity on metabolic syndromes sleep and stress in industry workers

Abstract

The purpose of this study was to investigate the effects of regular physical activity on industrial workers for one year and then to examine the influence on metabolic syndrome, sleep, and stress. The study subjects were 231 workers at Company H who were classified into three groups: no exercise, exercise once or twice a week, and exercise more than three times a week. Blood tests, sleep quality, and stress scores were examined before and after the study. Statistical analysis was performed using two-way repeated-measures ANOVA to determine if there were differences between groups and times, and when there was a significant difference, posttest was performed using Scheffe's test (p .05). After a regular 12-month physical activity program for industrial workers, there were significant differences in waist circumference and HDL cholesterol between the groups, but there were no significant differences in sleep quality or stress scores.
