The effectiveness of aerobic exercise intervention on physiological parameters and quality of life

摘要

Background: The workload, independent ability, environmental adaptation, work competitive increase pressure in workplace. "Karoshi" (death from overwork) may lead to sudden death. Therefore, it is very important to have healthy body and cultivate good lifestyle in the workplace for health promotion. Aim: This study aimed to investigate the effects of aerobic exercise on related physical parameters and quality of life among employees in the high-tech industries in southern Taiwan. Methods: A total of 75 employees were recruited in this study. They were randomly assigned to either experimental group (n=37) or control group (n=38). The aerobic exercise was used as intervention program in this study. Participants in the experimental group received 12 sessions (30 minutes /a session/ per week) of aerobic exercise. Participants in the control group received no intervention. The research instruments included physiological status, blood biochemical, fitness cases indices, quality of life, working pressure and job satisfaction. Results: The experimental groups' body weight, BMI, waist, and cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein were significantly decreased than control group by pair t-test (p＜0.05). Fitness comprised muscle endurance, flexibility, cardio- respiratory endurance were significantly different (p＜0.05). Quality of life, job control, interpersonal relationship in the workplace and job satisfaction showed significantly increased in the experimental group (p＜0.05) compared with the control group. Conclusion: This study suggests that aerobic exercise has effects to the weight loss, relaxation, promotion of the negative impacts of work stress; thus, enhance the physical health, job satisfaction and quality of life.
