Vitamin D Status in Spanish Elite Team Sport Players

Abstract

Low vitamin D is usual; however, data are limited for elite team players. The aim was to investigate the vitamin D levels in Football Club Barcelona (FCB) first division players of six sport modalities. Ninety-five elite male players (27.3 ± 4.6 y) belonging to FCB provided data for vitamin D throughout a season. In this study, 25(OH)D was measured in serum by chemiluminescent immunoassay. Outdoor/indoor training and supplementation were also considered. Total mean 25(OH)D concentrations were 91.9 ± 23.1 nmol/L in all players, with higher mean levels among supplemented players (94.7 ± 24.3 nmol/L). Around 25% of the team players were below optimal levels (<75 nmol/L), but none were below 50 nmol/L. Caucasian, supplemented football and handball players had the highest mean vitamin D concentrations over the whole year, whereas basketball players (indoor training) had the lowest ones. The highest rate of vitamin D insufficiency was found in spring (40%). A positive significant effect was observed for the interaction between indoor/outdoor training and supplementation with 25(OH)D concentrations (p < 0.05). Those team players training outdoors with supplementation had higher total vitamin D concentrations than those with indoors training and/or supplementation. A positive interaction of outdoor training with supplementation exists to determine 25(OH)D concentrations in team players.

Can the supplementation of vitamin D, sun exposure, and isolation during the COVID-19 pandemic affect the seasonal concentration of 25(OH)D and selected blood parameters among young soccer players in a one-year training season?

“…These results suggest that the effect of vitamin D supplementation does not last long, and constant dosing is needed during periods of deficiency ( Table 3 ). This thesis was supported by Valtueña et al [ 43 ], who reported that athletes who train indoors (e.g. handball, basketball, or volleyball players) and are not exposed to sunlight during training sessions obtain significantly lower values of 25(OH)D concentration than soccer players (who performed their sessions outdoor).…”

Incident Of Vitamin D Deficiency In Derna City\libya

“…CS openness or lack of Vitamin D alone didn't lessen the hypertrophic reaction of over-burden plantaris muscles, yet this hypertrophic reaction was debilitated when the two circumstances were joined. This information proposes that current smokers who likewise present with lack of Vitamin D might be more averse to react to a preparation program [38].…”

Personality Determinants of Eating Behaviours among an Elite Group of Polish Athletes Training in Team Sports

“…The results of the quantitative evaluation of diet among elite Polish basketball players allowed us to confirm the low supply of many nutrients, including dietary fibres and vitamins (B1, B9, C) and mineral salts (potassium, calcium, iodine) [ 20 ]. Among elite representatives of Spanish team sports, low blood levels of vitamin D3 have been described [ 44 ]. In this context, the importance of medical supplements recommended for athletes with vitamin and mineral deficiencies, including multivitamins, vitamin D and calcium, cannot be denied [ 7 , 9 ].…”
