Vitamin D Supplementation in Healthy Adults in Prolonged Endurance Exercise
- Conditions
- Healthy
- Interventions
- Dietary Supplement: Vitamin DDietary Supplement: Medium-chain triglycerides
- Registration Number
- NCT05781620
- Lead Sponsor
- Taipei Medical University
- Brief Summary
The purpose of this study is to investigate the effects of vitamin D supplementation on biochemistry response and skeletal muscle synthesis in prolonged endurance exercise.
- Detailed Description
Endurance exercise mode will be used to evaluate the effects of vitamin D supplementation on cardiac biomarkers, metabolic hormones, oxidative damage, and inflammation responses. An independent samples and dose titration design will be used to assign 30 participants to the experimental group (n = 15) or placebo group (n = 15). All participants in the experimental group will have serum 25(OH)D concentrations higher than 48 ng/mL after supplementation period. After the prolonged endurance exercise test, the blood samples will be collected for analyzing biomarkers. Data will be analyzed by Two-way mixed design ANOVA.
