Investigating Effects of Vitamin D Injection During A Course of Endurance Training on Anthropometrical Parameters of Wistar Rats With High-Fat Diet-Induced Obesity

Background and objectives: the purpose of this research was to determine effects of vitamin d supplementation during a course of endurance training on anthropometrical parameters of wistar rats exposed to a high-fat diet. methods: in this experimental study, 38 wistar rats aged 5-6 weeks were assigned to five groups: 1. control with normal diet (n=5), 2. control with high-fat diet (n=5), 3. high-fat diet and vitamin d supplementation (n=10), 4. high-fat diet and endurance training (n=10), and 5. high-fat diet, endurance training and vitamin d supplementation (n=10). the animals were subjected to a high-fat diet (40%) for 13 weeks, followed by 12 weeks of exercise and vitamin d supplementation. results: weight (p=0.02), bmi (p=0.001), lee index (p=0.01) and energy efficiency (p=0.001) differed significantly between groups 1 and 2. feed efficiency (p=0.03) and energy efficiency (p=0.01) of groups 2, 3 and 4 were significantly different from that of the control group. conclusion: the results of the present study indicate that endurance training and vitamin d supplementation could significantly decrease some anthropometric indices.
