Abstract
Cardiovascular diseases are one of the main causes of death in the world, which is associated with the imbalance of blood lipids. The aim of the present study was to investigate the effect of eight weeks of endurance training with vitamin D supplementation on lipid profile, blood pressure changes and body composition in overweight men.
In this study, 22 overweight volunteers (mean age 41.3± 4.42 years and body mass index (BMI) 28.5±4.75) were selected purposefully and randomly divided into 2 groups of 11 supplement and placebo. The training protocol consisted of eight weeks of running at 50-70% of the maximal heart rate, which was performed in three sessions per week. In each session, the intensity and timing of the training were increased. Triable in both groups received endurance training with vitamin D supplementation and endurance training with placebo once per every 14 days containing 50,000 units of vitamin D3 or placebo. Blood samples were collected in two stages before the start of the exercise protocol and 48 hours after the last exercise session in a fasting state. Blood pressure and body composition were measured before and after the exercise protocol in a fasting state. In order to analysis of the variance analysis tests with repeated measures, paired T-test and independent t-test were used to analyze the data.
The results showed that endurance training with and without vitamin D supplementation had a significant effect on lipid profile. Vitamin D3 supplementation also showed significant effects on high-density lipoprotein, low-density lipoprotein and triglyceride compared to the placebo group. Vitamin D3 supplementation had significant positive effects on systolic blood pressure, heart rate and serum levels of vitamin D. Endurance training in the study with and without vitamin D supplementation had a significant effect on body composition which these effects were greater in the supplementation group than in the placebo group.
Endurance training, as an appropriate strategy, probably can have positive effects on lipid profile, blood pressure changes and body composition in overweight men that vitamin D3 supplementation can improve outcomes.
