Vitamin D Supplementation in Healthy Adults in Prolonged Endurance Exercise

Not Applicable
Active, not recruiting
Conditions
Healthy
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.
