Vitamin D and the Athlete: Current Perspectives and New Challenges.

摘要: The last decade has seen a dramatic increase in general interest and research into vitamin D, with many athletes now taking D supplements as part of their everyday dietary regimen. most recognized role is its regulation calcium homeostasis; there strong relationship between bone health non-athletic individuals. In contrast, data have consistently failed to demonstrate any serum 25[OH]D health, which may be due the osteogenic stimulus exercise. Vitamin interact extra-skeletal tissues such muscle immune system modulate recovery from damaging exercise infection risk. Given that engage supplementation, often consuming extreme doses it important assess whether excessive can detrimental health. It been argued toxic effects only occur when concentrations are greater than 180 nmol·l−1, but our laboratory suggested high-dose supplementation could problematic. Finally, paradoxical concentration, ethnicity, markers health: Black present low without physiological consequences. One explanation for this genetic differences binding protein resulting bioavailable (or free) some ethnic groups. absence pathology, screening unnecessary result incorrect supplementation. Data must re-examined, consideration or “free” ethnically diverse groups enable new thresholds target established; perhaps, now, time “set free”.
