This study aim at describing the relations between daily average steps (DAS), body compositions and hemodynamic indices in female college students varying in daily steps, and is to evaluate cause and effect indicators impacting pedometer-determined steps and abdominal obesity. Participants in this study were female college students (n=22) who were divided into two groups(under 5,000 steps/day: IAG, n=8; more than 5,000 steps/day: SAG, n=14) on the basis of mean daily 5,000 steps. The t-test assesses whether the actual differences of two groups are statistically significant from each other. Multiple regression analysis was used for prediction of the relationship between dependant variables (daily steps, abdominal obesity) and independent variables (the indicators of body compositions and hemodynamics). The results are listed as follows: First, IAG`s DAS in college female students were about 3,600 steps, however, SAG walked about 6,300 steps per day. Second, IAG showed significantly higher level of the indicators of obese and lean body mass. However, when these indexes compared to body-weight ratio, SAG was significantly low in obese factors and high in lean body mass variables. Third, the increase or decrease in steps and abdominal obesity of IAG accompanied by the increase or decrease in body composition indicators, while SAG accompanied by the increase or decrease in hemodynamic indices. Therefore, the possibility of getting under 5,000 steps per day in female college students was about 38 percentage. Evaluating the relationship between steps per day and body compositions was needed to estimate the ratio of body composition variables to body weight. This study suggests that obese persons with low exercise quantity need to concentrate on improve body composition variables, and that normal body weight individuals with somewhat amount of exercise is necessary to focus on managing hemodynamic parameters.
