Postural Alignment and Body Fat Percentage as Associated Factors of Injury Risk in Students Athletes

This study aims to describe postural alignment and body fat percentage as factors associated with the risk of injury among student athletes. This study employed a quantitative descriptive design with a sample of 107 student athletes from the Faculty of Sports Science at Semarang State University, selected through purposive sampling. Postural alignment was measured using APECS for the ear, shoulder, ASIS, knee, foot, and overall alignment components, while body fat percentage was measured using calipers at three points for both men and women. The results showed that the greatest postural deviations were found in the foot segment, with a maximum value of 11°, and in the knee segment, with a maximum value of 9°, while the average body fat percentage among men was 14.91 ± 6.67%, with 48.8% of respondents falling into the “athlete” category. For women, the average body fat percentage was 26.98 ± 4.93%, and the majority fell into the average category (42.9%). These findings indicate that there is still variation in postural alignment and body composition among student athletes, which has the potential to affect biomechanical efficiency, movement stability, and susceptibility to injury.
