Relationship between 25-hydoxyvitamin D, muscle strength, and incidence of injury in healthy adults: a systematic review

Muscular effects of vitamin D in young athletes and non-athletes and in the elderly

“…48 Since then, several cross-sectional observations and longitudinal studies have established a close association between vitamin D and several parameters of neuromuscular performance. The majority of these studies have been performed in the elderly, although similar data have also been reported in adults below the age of 65 49 and in the young. 50,51 In the CHIANTI study, physical performance was assessed in more than 900 individuals aged 65 or older and physical performance was assessed at baseline.…”

Vitamin D and Physical Activity

“…To date, several cross-sectional observations and longitudinal studies have reported a close association between vitamin D and several parameters of physical performance. The majority of the studies have been performed on elderly subjects although similar data have been reported in adults below the age of 65 years [160] and in young individuals [161,162]. In the elderly vitamin D deficiency has been associated with myopathy, reduced muscle mass and strength, low exercise performance, and an increased risk of falling [163].…”

Acute Effects of Vitamin D3 Supplementation on Muscle Strength in Judoka Athletes

“…Vitamin D 3 supplementation doses have also varied considerably with interventions of 200 to 100 000IU over 3 to 12 month of periods. 14,20 However, the longer the intervention the more likely, it is that other variables could affect the final outcome. Wyon et al 7 noted an improvement in muscle strength and power, and a decrease in injury incidence over a 4-month supplementation intervention period (2000IU/d).…”
