Effects of Vitamin D3 Supplementation and Resistance Training on 25-Hydroxyvitamin D Status and Functional Performance of Older Adults: A Randomized Placebo-Controlled Trial.

Synthesis<\/h3>\n

The study aims to demonstrate the effects of vitamin D supplementation on the functional performance of the elderly, undergoing a physical resistance training.<\/span><\/p>\n

Although there is no clear evidence about the positive role of this supplementation on muscle strength, it is reiterated that physical activity brings a clear benefit to the subjects recruited.<\/span><\/p>\n

In addition, it is shown that the monthly administration of Vitamin D appears more effective than the daily one in the treatment of hypovitaminosis D.\u00a0\u00a0<\/span><\/p>\n

Background<\/h3>\n

It\u2019s known aging is related to a loss of muscle mass and neuromotor power.\u00a0<\/span><\/p>\n

To prevent these processes, the effectiveness of physical activity aimed at resistance training is proven.<\/span><\/p>\n

In addition, vitamin D seems to be a valuable tool in combating age-related deterioration, although its precise role in increasing muscle mass and function is still debated.<\/span><\/p>\n

Characteristics of the study<\/h3>\n

To investigate the role of Vitamin D on the functional performance of the elderly with hypovitaminosis D, a randomized-controlled double-blind study was conducted.\u00a0<\/span><\/p>\n

100 participants, aged between 65 and 85, were recruited, divided into three groups:\u00a0<\/span><\/p>\n

–\u00a0 control group (CON)<\/span><\/p>\n

– group with daily supplementation of 800 IU of Vitamin D (VDD)<\/span><\/p>\n

– group with monthly supplementation of 50000 IU of Vitamin D (VDM).<\/span><\/p>\n

The study was divided into two phases<\/strong>:\u00a0<\/span><\/p>\n

–\u00a0 the first with vitamin D supplementation or placebo without physical activity<\/span><\/p>\n

–\u00a0 the second with the addition of an resistance training program.\u00a0<\/span><\/p>\n

This program, based on the American College of Sports Medicine and American Heart Association guidelines, consists of 10 weeks of training (2 sessions per week, lasting 60-90 minutes).<\/span><\/p>\n

Results<\/h3>\n

Patients were evaluated with specific motor function tests: chair stand test, arm curl test, 6 minutes walking test, gait speed and time up and go test. Moreover, blood dosages of Vitamin D were performed.\u00a0<\/span><\/p>\n

Regarding Vitamin D, monthly administration is more effective to reach the recommended blood levels.<\/span><\/p>\n

In all three groups, tests improved as a result of starting physical activity. However, no improvement has been observed in relation to the different administration of vitamin D in the three groups.<\/span><\/p>\n

What is new?<\/h3>\n

Monthly vitamin D supplementation is better to daily supplementation to achieve adequate blood levels.\u00a0<\/span><\/p>\n

A clear role in the muscular performance of the elderly remains to be proven.<\/span><\/p>\n

Perspectives<\/h3>\n

While it is proven the effectiveness of Vitamin D in several aspects, such as prevention of fractures, falls, cardiovascular risk and immuno- stimulation, its correlation with muscle function is still to be clarified.<\/span><\/p>\n
