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.<br> <strong>Results:</strong> 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.<br> <strong>Conclusion:</strong> The results of the present study indicate that endurance training and vitamin D supplementation could significantly decrease some anthropometric indices.<br> <strong>Keywords:</strong> Endurance Training, Vitamin D, High Fat Diet, Anthropometric Indices.</div> Endurance Training, Vitamin D, High Fat Diet, Anthropometric Indices 36 43 http://mlj.goums.ac.ir/browse.php?a_code=A-10-583-2&slc_lang=en&sid=1 Seyed Javad Mirghani seyedgavadmirghani@yahoo.com 100319475328460016683 100319475328460016683 No Department of Exercise Physiology, Faculty of Physical Education and Sports Science, Islamic Azad University, Central Tehran Branch, Tehran, Iran1 Mohammad Ali Azarbayjani ali.azarbayjani@gmail.com 100319475328460016684 100319475328460016684 Yes Department of Exercise Physiology, Faculty of Physical Education and Sports Science, Islamic Azad University, Central Tehran Branch, Tehran, Iran1 Maghsood Peeri m.peeri@gmail.com 100319475328460016685 100319475328460016685 No Department of Exercise Physiology, Faculty of Physical Education and Sports Science, Islamic Azad University, Central Tehran Branch, Tehran, Iran1 Abbasali keshtkar abkeshtkar@gmail.com 100319475328460016686 100319475328460016686 No Department of Health Sciences Education Development, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran 2
