Effetcs of badminton and ice hockey on bone mass in young males: a 12-year follow-up
(English)Manuscript (preprint) (Other academic)
The purpose of the present study was to investigate the influence of different types of weight bearing physical activity on bone gain during an active sports career and to identify any residual benefits in BMD after the active sports career. Beginning at 17 years of age, BMD was measured 5 times, during 12 years, at multiple sites in 19badminton players, 48 ice hockey players and 25 controls. Levels of vitamin D and fatty acids were also evaluated in relation to changes in BMD during the study. During the time the athletes were active, badminton players were found to have gained significantly more BMD in their femoral neck, humerus, and lumbar spine in comparison to control subjects (mean difference = 0.05-0.17 g/cm2, p < 0.05 for all), and significantly more in their legs compared to both ice hockey players and controls (mean difference = 0.03-0.05 g/cm2, p < 0.05). At final follow-up, badminton players had significantly higher BMD of the femoral neck, humerus, lumbar spine and legs (mean difference = 0.08-0.20 g/cm2, p<0.01 for all) than both ice hockey players and controls. Levels of vitamin D and fatty acids were not related to changes in BMD at any bone site (p > 0.05 for all). In summary, the present study suggests that badminton is a more osteogenic sport and therefore related to greater gains in BMD compared to ice hockey. These BMD benefits were partly sustained with reduced activity.
