Inadequate vitamin status is inversely related to adiposity, risk of falls, and muscle weakness, particularly in the elderly. We examined the relationship of 25‐hydroxyvitamin D (vitamin D) concentration to overall physical fitness indices (central adiposity, strength, balance) in 122 healthy postmenopausal women. Covariates included: age or time since last menstrual period (TLMP); weight; energy expenditure; dietary energy, protein, fat; and calcium intake throughout life. Overall and regional body composition (androidal fat mass=waist+hip fat) was assessed via dual‐energy X‐ray absorptiometry. Regression analyses revealed that 12.8% of variability ( p =0.0029) in androidal fat mass was accounted for by vitamin D (4.7%, p =0.013), TLMP (3.0%, p =0.046), omega‐3 fatty acid intake (3.1%, p =0.045), and calcium intake during childhood (2.2%, p =0.089); 13.0% of variability ( p =0.0009) in balance (right+left leg) was accounted for by age (6.6%, p =0.003), vitamin D (2.5%, p =0.068), and weight (2.5%, p =0.069); and 15.4% of variability ( p =0.0002) in hand grip strength (right+left) was accounted for by weight (11.0%, p =0.0002), age (3.2%, p =0.037), and vitamin D (2.7%, p =0.057). Results indicated that vitamin D was the common contributor to physical fitness indices (androidal fat mass, leg balance, grip strength) in healthy postmenopausal women.
