This study aimed to examine the effects of 10 weeks of accumulation of short duration exercise on physical fitness, lifestyle disease indices and psychological stress in obese male office workers aged 30-40s with body mass index of 25 kg/m² or higher and PSS score of 20 or above. Participants in training group (TR; n=15) participated in accumulation of short duration exercise three times of 10-min exercise/day, 3 days/week for 10 weeks, whereas participants in control group (CON; n=15) maintained their normal life patterns for the same intervention period. Dependent variables were measured and analyzed using a two-way repeated measures ANOVA. Main results of the present study were as follows: 1) Fat mass, percent body fat, waist circumference, and waist-hip ratio decreased significantly in the TR. 2) Grip strength, sit-ups, and push-ups improved significantly in the TR. 3) Fasting blood glucose improved significantly in the TR. 4) High density lipoprotein cholesterol (HDL-C) increased significantly in the TR. 5) TC/HDL-C and LDL-C/HDL-C improved significantly in the TR. 6) Diastolic blood pressure and mean arterial pressure decreased significantly in the TR. 7) PSS (perceived stress scale) and KOSS (Korean occupational stress scale) scores improved significantly in the TR. It was concluded that the 10 weeks of accumulation of short duration exercise would be beneficial for improving body composition and physical fitness in obese male office workers, and it may help prevent various lifestyle diseases as well as reduce psychological stress.
