A Study on Health and Physical Fitness for Office Workers in Hong Kong: Phase II
LANGUAGE NOTE | Document text in Chinese; abstract in English only.
The study consisted of two phases: Phase I was designed to investigate the health and physical fitness status of office workers and phase II was conducted to examine the training effects of a circuit training program on health and physical fitness of the workers. In phase II，100 subjects (50 males & 50 females), randomly selected from the participants (112 males & 59 females, aged 30-49) of phase I, were randomly assigned to experimental groups and control groups (25 subjects per group). Subjects in experimental group received a 8-week, 2 times a week with 1 hour per session circuit training program while subjects in control group were not receiving any physical training. The ANCOVA analyses revealed that subjects in both gender of the experimental groups had significant (p < .05) improvement on the health and fitness indices which included grip strength, abdominal muscular strength and endurance, trunk flexibility, cardiorespiratory endurance, resting heart rate, and forced vital capacity. Body fat and stress levels (Pace of Life Index) were also significantly (p < . 05 ) reduced for both sexes after the 8-week circuit training. However, there were no training effects on general health concerns (General Well-Being Scale), cholesterol levels, and blood pressure in this study. As the related research indicated that workers with higher levels of physical fitness would have higher working ability and productivity, it was suggested that local office workers should give priority to regular physical activity. Circuit training, which consists of aerobic exercises, calisthenics, stretching, and muscular training in a workout period, is time saving and highly desirable for local office workers to promote their health and fitness.
