Objectives: A number of studies have shown a greater Bone Mineral Density (BMD) in athletes compared to sedentary population. The aim of the present study was to investigate if a BMD advantage is retained after the termination of soccer career.
Materials and methods: 41 male former soccer players (age 53-61 years) representing five teams of national level were compared to non-athletic controls (n=40). Former players had ended their careers approximately 22 years preceding the study. Body composition and total body, lumbar spine and femur BMD were measured using dual-energy X-ray absorpsiometry among all participants. Participants also filled in a questionnaire to specify their current level of physical activity (Kriska et al., 2007). For the statistical analyses, the students\' t - test, analysis of covariance (ANCOVA) adjusting for age, weight and BMI and the Mann-Whitney U-test were used. Statistical significance was set at the 0.05 level.
Results: Soccer players had significantly greater BMD than controls at all sites measured. Greater differences were observed at the proximal femur sited (9.7-10.3%) than at the lumbar spine (3.6%) or for the total body (2.1%). No BMD differences were observed between teams representing different types of training. Former soccer players had retained their proximal femur and total-body BMD advantage over matched controls.
Conclusions: Soccer has a positive effect on BMD and this advantage is retained to an extent after the termination of the athletes\' career. Thus, a positive effect on future fracture risk can be expected.
