Relationship between body composition and bone mineral density in American football players
Keywords:American football, bone mineral density, lean mass, DEXA, BMI
Objectives: The objective of this study was to assess the relation between body composition and body mass index (BMI) to bone mineral density (BMD) in college American football players.
Methods: A total of 90 players (22.44 + 1.71 years old) from the major college football league in Mexico participated. The dual-energy X-ray absorptiometry (DEXA) equipment was used, in which the values of BMI, fat mass, lean mass, total mass and BMD were obtained.
Findings: Players who had higher BMI got higher BMD. The strongest significant positive correlations found were lean mass, body weight, and BMI with BMD of the arms, legs, trunk, and spine.
Conclusions: Most of the players analyzed had problems of excess weight and obesity, however, those who had a higher BMI such as obesity type I, II and III had also higher BMD than those with excess weight and normal weight, with significant differences in the regions of arms, legs, spine and total body.
