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.

Objetivos: El objetivo de este estudio fue relacionar el índice de masa corporal (IMC) y la composición corporal con la densidad mineral ósea (DMO) en jugadores de fútbol americano universitario. Métodos: Participaron un total de 90 jugadores (22.44 + 1.71 años de edad), de la liga mayor de fútbol americano universitario en México. Se utilizó el equipo de la absorciometría dual de rayos X (DEXA), en la cual se obtuvieron los valores del IMC, masa grasa, masa magra, masa total y la DMO. Resultados: Los jugadores que presentaron un mayor IMC obtuvieron una mayor DMO. Conclusiones: si observamos que la mayoría de los jugadores suelen tener problemas de sobrepeso y obesidad, encontramos que la masa grasa no se asocia con la DMO, es decir, que el jugador a pesar de tener un peso corporal elevado, su beneficio de la elevada DMO se debe a la alta cantidad de masa magra.
