Abstract

Aim. To determine the effect of ultraviolet on vitamin D activation and balance in postmenopausal woman. Materials and methods. This study was conducted on forty postmenopausal women suffering from vitamin D deficiency (diagnosed by physician), with their age ranged from 50 to 60 years. They were randomly assigned into two equal groups. Group (A) received ultraviolet for 12 weeks (n = 20), while group (B) served as a control group (n = 20). Vitamin D was evaluated by blood analysis while balance was evaluated by Biodex balance system before and after treatment for both groups. Results. Comparing both groups post-treatment showed that there was a statistically significant increase in vitamin D (p < 0.05) and statistically significant reduction in all balance indices (p < 0.05) in favor of group (A). Conclusions. Ultraviolet radiation is effective, easy to apply, simple and successful method in improving vitamin D concentration and balance in postmenopausal women.

Abstract
Aim. To study the impact of physical activity carried out both outdoor and indoor on vitamin D status based on systematic review of literature from various studies.
Materials & Methods. Systematic literature survey was carried out by searching electronic databases including PUBMED, Cochrane library & Google Scholar and was investigated until March 2018 for all case–control studies evaluating the association between physical activity and vitamin D.
Results. Various studies demonstrated that the study participants who took part in physical activity showed positive correlation with both improved 25(OH) levels and significant improvement in quality of life. Few studies attributed rise in vitamin D levels to physical activity done indoors signifying that levels of vitamin D are not improved by solar exposure alone. Hence, though different studies have revealed clear relationship between physical activity and vitamin D in adults, the outcomes were not uniform.
Conclusion. The current review is a collective narrative of various studies that have been carried out in the past (especially over the last decade) to assess the association between vitamin D status and physical activity. Most studies included in the review indicate clearly that there is an elevation in plasma vitamin D concentration in response to physical activity both outdoors and indoors.
