The purpose of this study was to know the bone changes of college football (FA) players. A total of 39 male FA players participated, ranging in age from 18 to 25 years old. They were grouped according to each playing position they play in the team such as: Linemen (n = 15), players of great skills (n = 7), players of skill (n = 13) and quarterbacks (n = 4). For the assessment of BMD (g/^cm2) a Double X-ray Bone Densitometry (DXA) was used.  The results of this study showed a significant decrease (p<.05) of BMD in head and legs, in contrast, the CMO showed an increase in legs, however, in the pelvic region showed a significant decrease (p<.05). In conclusion, significant changes were found for BMD and CMO in the head, leg and pelvis regions in college AF players over a one-year span of competition.
