“…Whilst studies around the globe have demonstrated that vitamin D insufficiency/deficiency is a health concern affecting athletes [2]; not all elite cohorts have exhibited clinical deficiency, in support of the current findings [15,16,17,18,19,20,21,22]. Unlike the majority of athletes, those competing at the elite level have access to a support network of dietitians that regularly monitor dietary intake and nutrient status by analysis of food diaries and blood screening.…”

Vitamin D Status and Supplementation Practices in Elite Irish Athletes: An Update from 2010/2011

Vitamin D deficiency is a global health concern that is prevalent in Ireland. The vitamin D status of elite Irish athletes following implementation of a revised supplementation policy in 2010/2011 has not been explored to date. This study aimed to assess the vitamin D status of elite Irish athletes participating in high-profile sports and establish if equatorial travel, supplementation and/or sunbed use predict vitamin D status. Across Ireland, blood samples (n = 92) were obtained from cricketers (n = 28), boxers (n = 21) and women’s rugby sevens players (n = 43) between November 2013 and April 2015. Total 25-hydroxyvitamin D (25(OH)D) concentrations were quantified using LC-MS/MS. Parathyroid hormone and adjusted calcium concentrations were measured by clinical biochemistry. Athletes completed a questionnaire that queried equatorial travel, supplementation and sunbed use. Vitamin D sufficiency (25(OH)D >50 nmol/L) was evident in 86% of athletes. Insufficiency (31–49 nmol/L) and deficiency (<30 nmol/L) was present in only 12% and 2% of athletes respectively. On average, athletes from all sport disciplines were vitamin D sufficient and 25% reported vitamin D supplementation which was a significant positive predictor of vitamin D status, (OR 4.31; 95% CI 1.18–15.75; p = 0.027). Equatorial travel and sun bed use were reported in 47% and 16% of athletes respectively however these factors did not predict vitamin D status (both p > 0.05). Although different cohorts were assessed, the overall prevalence of vitamin D insufficiency/deficiency was 55% in 2010/2011 compared with only 14% in 2013/2015. Targeted supplementation is highly effective in optimising vitamin D status, negating the need for blanket-supplementation in elite cohorts.

“…Our group previously demonstrated no association between serum 25(OH)D and markers of bone health in weight bearing athletes of different racial background, suggesting that markers of bone health are independent of serum 25(OH)D concentrations 18. It appears there is a ‘paradoxical relationship’ between race and vitamin D concentration that has largely been ignored, that is, Black individuals generally have the lowest serum 25(OH)D concentrations but the greatest BMD and reduced risk of fracture 14 19.…”

“…For example, athletes and well‐trained individuals that participate in dynamic exercises such as long‐distance running have an increased cardiac output, driven by an elevated stroke volume and lower heart rate (McArdle & Katch ). Indeed, it is well‐established that the physiology of the heart is dependent upon the modality of sport, age, ethnicity, genetics and body composition (Allison et al ). Although research to date has not focused on the direct effects of vitamin D supplementation on healthy cardiac morphology, a cross‐sectional study conducted in 506 international professional athletes (football, handball, volleyball and basketball players) from Qatar found that those with a 25(OH)D concentration classed as ‘severely‐deficient’ or ‘deficient’ (<25 and 25–50 nmol/l, respectively) had a smaller aortic root, right atria, left atria diameters, intraventricular septum diameter, left ventricular diameter and left ventricular mass (Allison et al ), which are likely to negatively affect cardiac output.…”

The primary source of vitamin D is through synthesis in the skin, following exposure to sunlight containing ultraviolet B (UVB) radiation. Supply through skin exposure can be supplemented by the diet, but there are relatively few dietary sources, especially those which provide a large amount of vitamin D per serving. Research into the effects of vitamin D status in different population groups has become an increasingly popular topic. The current interest surrounding vitamin D research in sport remains focused on the potential ergogenic effects of vitamin D on physical performance. However, the relationship between vitamin D (dietary intake and status) and musculoskeletal health in university athlete cohorts residing at higher latitudes (>40°N) remains underinvestigated. Within this review, the possible physiological roles that vitamin D may play within sport performance for recreational and professional athletes, as well as military recruits, will be discussed. The focus will be on muscular strength, cardiovascular health and the incidence of illness, including upper respiratory tract infections. Specifically, the effect that vitamin D deficiency {defined as a plasma/serum 25‐hydroxyvitamin D [25(OH)D] concentration of <25 nmol/l} may have on musculoskeletal health, including the incidence of stress fractures, is discussed. The review also seeks to highlight avenues for future research within vitamin D and sport, in particular for populations residing at higher latitudes (>40°N) where wintertime vitamin D deficiency is prevalent. It is hoped that this review will help to raise the awareness of the importance of existing advice in the UK for the avoidance of vitamin D deficiency and international vitamin D guidelines (such as in the US) on the achievement of vitamin D sufficiency [serum 25(OH)D >50 nmol/l] for optimum health and performance in athletes, both professional and recreational.

Severely vitamin D-deficient athletes present smaller hearts than sufficient athletes

Abstract: Severely 25(OH)D-deficient athletes present significantly smaller cardiac structural parameters than insufficient and sufficient athletes. Future research should investigate the precise mechanism(s) causing cardiac hypertrophy with increases in serum 25(OH)D in healthy athletes.
