The purpose of this study was to investigate the changes of physique and physical fitness in 105 male factory workers in a year. As physical measurements, body height, body weight, body mass index (BMI), body fatness and the waist to hip ratio (WHR) were measured. Examined physical fitness consisted of grip strength, standing trunk flexion, foot balance with closed eyes, vertical jump, whole body reaction time and breath holding time. Between the ages of 20 and 39, overweight group (OW-Y, 24≦BMI≦33.7) consisted of 19 subjects and non-obese group (NO-Y, 15.9≦BMI<24) was consisted of 50 ones. On the other hand, between the ages of 40 and 59, overweight group (OW-0) was composed of 16 subjects and non-obese group (NO-O) was composed of 20 ones. All parameters were measured in 1996 and 1997. In OW-0, ability of vertical jump deteriorated from 48.0 to 43.9 cm (p<0.05) and size of waist increased from 90.2 to 92.1 cm (p<0.05). In NO-Y, size of hip and WHR increased from 73.5 to 75.1 cm, and 0.80 to 0.82, respectively (p<0.05). The findings of this study suggest NO-Y, compared with NO-O, easily increases body fatness. And also, OW-O, compared with OW-Y, easily becomes fattier and ability of vertical jump remarkably deteriorates. Therefore, medical staff, especially nurses, should educate the workers to became aware that the overweight and obesity affect their physical fitness, and instruct them of proper life-style to keep their health well.
