여자 대학생의 골밀도와 건강체력 간의 상관관계

Abstract

Whether health-related physical fitness test items relate to bone mineral density remain less clear. We investigated the associations of bone mineral density with physical fitness test items in 145 female college students. Bone mineral density (T-score) was measured by quantitative ultrasonography, while physical fitness test items (strength, sit-up, sit and reach, body composition, and cardiorespiratory fitness(PEI) were assessed by using standardized protocols. Pearson correlation coefficients show that T-score was positively associated with muscular strength (r = 0.22, p<0.001), sit-up (r = 0.30, p<0.001), sit and reach (r = 0.23, p<0.001), and PEI (r = 0.35, p<0.001). In contrast, T-score was negatively associated with percent body fat (r = -0.23, p<0.001). We conclude that health-related physical fitness test items are associated with bone mineral density in female college students.
