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

Abstract

Background and Aim: Exercises to reduce respiratory symptoms of asthma and Vitamin D by regulating the immune system can play a significant role in the health of asthmatic patients. The purpose of the present study was to investigate the effect of short-term consumption of vitamin D supplements following a session of increasing activity on respiratory parameters and tolerance to activity of women with mild asthma. Materials and Methods: This study was quasi-experimental based on the pre-test and post-test pattern that following the announcement of the call, 30 asthmatic women volunteered in Ahwaz was performed. Ballk test for cardiopulmonary patients was used for increasing aerobic exercise. Supplementation with vitamin D tablets at a dose of 1000 units daily was performed for six weeks. For evaluation of pulmonary Vital Capacity (VC) and Maximum Voluntary Ventilation (MVV) indices, the Spirometer device was used. To determine normality of the data was used Shapiro-Wilk's test and data analysis by using paired t-test. Results: The results showed that after the intervention, there was a significant difference in VC and MVV levels and tolerance to activity in the pre-test, supplementation and exercise stages (P≤0.05.( Conclusion: Taking vitamin D supplementation with aerobic exercise can improve respiratory function in asthmatic patients and increase tolerance to activity.
