Background: Physical inactivity and reduced energy expenditure lead to increase in obesity among office workers. In this study, we investigated how 10 weeks of high intensity circuit training and working environment improvement can change body composition, physical strength and markers of metabolic syndrome.
Methods: A total of 83 employees at risk for metabolic syndrome participated in 10 weeks program of one-hour circuit training (30 minutes twice weekly) and workplace improvement program, which consisted of dynamic stretching twice daily for all weekdays. Body composition, anthropometry, blood test, muscle strength/endurance and cardiopulmonary function of participants were assessed at the baseline and after 10 weeks.
Results: At the end of 10 weeks, significant increases in levels of body composition, serum lipids, muscle strength and cardiopulmonary were observed in metabolic syndrome risk factor group. In body composition, significant improvements of body weight, body mass index, lean body mass, %body fat, visceral adipose tissue, waist and hip circumference and systolic blood pressure, diastolic blood pressure were observed in metabolic syndrome risk factor group. In lipids, hemoglobin A1c and high density lipoprotein were increased significantly in metabolic syndrome risk factor group. In muscle strength and endurance, significant increases were found. Also, there was a significant difference in cardiovascular function of maximal oxygen uptake and total running time among the groups.
Conclusions: These intensive 10 weeks of high intensity circuit training and workplace improvement program were effective in improving body composition, muscle strength/improvement and cardiopulmonary function. Therefore, based on this study result, workplace improvement programs might be more developed and applied for high-risk employees to improve their metabolic syndrome.
