Background: The impact of vitamin D on musculoskeletal health is well-established, although its influence on physical performance is unclear. Therefore, we conducted this study to evaluate the impact of 25-hydroxy-vitamin D (25-OH vitamin D) concentrations with maximal aerobic power of professional indoor athletes.

Results: A total of 112 male professional athletes were included in this cross-sectional study, consisting of 88 handball and 24 ice hockey players. The maximal aerobic power was assessed with a standardized cycling ergometer test. Athletes were assigned to two groups according to their 25-OH vitamin D status: insufficient (< 30 ng/mL) and sufficient (> 30 ng/mL). Thirty-four players (30.4%) displayed insufficient (21.9 ± 5.9 ng/mL) and 78 (69.6%) sufficient 25-OH vitamin D concentrations (41.6 ± 8.6 ng/mL). Athletes with sufficient levels achieved a higher maximal aerobic power (3.9 ± 0.9 vs. 3.5 ± 0.8 W/kg, p = 0.03) compared to those with insufficient levels.

Conclusions: There is a high prevalence of 25-OH vitamin D insufficiency in professional indoor athletes, even in summer. Insufficient 25-OH vitamin D concentrations were associated with lower maximal aerobic power in male professional indoor athletes. Further, the 25-OH vitamin D concentration was identified as the only independent predictor of maximal aerobic power in these athletes, highlighting the impact of 25-OH vitamin D on physical performance. Therefore, 25-OH vitamin D concentrations of > 30 ng/mL should be maintained to ensure optimal physical performance in these athletes.

VitaminDWiki - Overview Sports and vitamin D

Athletes are helped by vitamin D by:

  1. Faster reaction time
  2. Far fewer colds/flus during the winter
  3. Less sore/tired after a workout
  4. Fewer micro-cracks and broken bones
  5. Bones which do break heal much more quickly
  6. Increased VO2 and exercise endurance Feb 2011
  7. Indoor athletes especially need vitamin D
  8. Professional indoor athletes are starting to take vitamin D and/or use UV beds
  9. Olympic athletes have used UV/vitamin D since the 1930's
  10. The biggest gain from the use of vitamin D is by those who exercise less than 2 hours per day.
  11. Reduced muscle fatigue with 10,000 IU vitamin D daily
  12. Muscle strength improved when vitamin D added: 3 Meta-analysis
  13. Reduced Concussions
