The effect of short-term consumption of vitamin D Supplements following a session of increasing activity on respiratory parameters and toleratance to activity of women with mild asthma

 Exercise reduction of respiratory symptoms of asthma and Vitamin D by adjusting the immune system can have a significant effect on the health of asthmatic patients. The purpose of this study was to investigate the effect of short-term vitamin D supplementation following a session of increased activity on respiratory parameters and activity tolerance in women with mild asthma.

  This study was quasi-experimental based on pre-post test That Following the announcement of the call, on thirty asthma women volunteered in Ahwaz performed. Balk test for cardiopulmonary patients was used for increasing aerobic exercise. Supplementation with vitamin D tablets at a dose of 1000 units daily for six weeks. About evaluation of pulmonary function we used Vital Capacity (VC) and Maximum Voluntary Ventilation (MVV) indicators by Spirometry devises. In order to determine normality of the data was used Shapiro-Wilk's test, T-test was used to analyze the data.

   Results indicated that there was a significant difference between VC and MVV levels and Activity tolerance to pre-test, supplement and exercise levels after the intervention (P ≤ 0/05.(

 Taking vitamin D supplementation with aerobic exercise can improve respiratory function in asthmatic patients and increase tolerance to activity.
