The purpose of this research was to confirm how the daily walk rate affect to body composition factors and hemodynamic indicators, and what connections does the (research) variables have one another depends on average daily steps. For this research, 22 female students volunteered and we checked their total walk steps for a week, then we separated a group (inactive group, IAG, n=8; somewhat active group, SAG, n=14) of 5,000 daily walk rate and less than. Also, we check over their minerals, muscle mass, lean body mass, WHR(waist-to-hip ratio), and BMI(body mass index) in factors of body composition, and SBP(systolic blood pressure), DBP(diastolic blood pressure), HR(heart rate), TP-KS(pulse wave konotkoff sound, systolic time), PRP(pressure rate product), CO(cardiac output), and TPR(total peripheral resistance) in hemodynamic indicators. Then we analyzed the difference and connection between research factors and average daily walk rate. The results were as follows.
First, in body composition, IAG has significantly higher of minerals, muscle mass, lean body mass, WHR and BMI than SAG.
Second, in hemodynamic indicators such as SBP, DBP, PRP, IAG was significantly higher than SAG.
Third, in IAG, average daily walk rate was related to factors of body composition. However, hemodynamic indicators was not so(is not related to). Average daily steps was not related to all of body composition and factors of hemodynamic indicators in SAG.
Fourth, in IAG, factors of body composition such as SBP, DBP have significant connection one another. However, there were no significant relationships between body composition and hemodynamic indicators in SAG.
To sum up, female college students who walked more than 5000 daily steps were significant high in lean body mass and low in abdominal obesity per kg of body weight. Female college students who walked less than 5000 daily rate showed significant relationships in body composition variables. Therefore, this study showed the results that female college students with average daily steps of more than 5000 were in high level of muscle mass, lean body mass, and in low level of obesity-related risk factors.
