Introduction

Bone mineral density (BMD) is a critical indicator of bone health, often influenced by high-impact physical activity during adolescence. This study aimed to evaluate the impact of sports activities during high school on BMD in university freshmen.

Materials and methods

In this comparative retrospective cohort study, university freshmen were surveyed regarding their previous high school sports activities and categorized based on impact loading characteristics: non-impact, multidirectional, high-impact, and low-impact sports. BMD was measured using an ultrasound bone densitometer for the calcanea and expressed as speed of sound (SOS). Statistical analyses included one-way analysis of variance with post-hoc testing to compare SOS among the groups.

Results

The sample included 240 athletes (167 males and 73 females, aged 18.5 ± 0.7 years). The high-impact and multidirectional sports groups exhibited significantly higher SOS values than the non-impact sports group. Sports such as soccer and track and field sprints were associated with higher SOS values than swimming.

Conclusions

This study indicates that university freshmen who participated in high-impact and multidirectional sports during high school exhibited higher BMD values. These findings underscore the importance of engaging in high-impact and multidirectional activities during adolescence for bone health.
