The effect of high-dose vitamin D supplementation and an exercise program to lose weight on some biochemical variables of overweight women

Background and Study Aim. In recent years, there has been a technological revolution and development in all fields, particularly the sports field. This has imposed on man a lifestyle characterized by comfort at the expense of a significant portion of his movement and activities. The problem of obesity has expanded beyond the inconsistency of the body to include its direct effect of increasing the proportion of fat and the negative impact on the work of vital organs. This disruption alters the body's internal environment and causes numerous diseases. The purpose of this study is to determine the effect of a sports program on taking vitamin D to lose weight and on some biochemical variables in young adults aged 30 to 35 years old. Materials and Methods. The study involved 10 overweight women aged 30-35 years, selected through intentional sampling. Inclusion criteria required consent, good health, and no ongoing vitamin D or exercise programs. The research employed a Randomized Controlled Trial (RCT) design. Primary outcome measures encompassed body weight, body composition, lipid profile, and vitamin D status. Anthropometric measurements included age, height, weight, and training age. Biochemical measurements involved blood tests for cholesterol, triglycerides, and vitamin D levels. The experimental group received vitamin D tablets and a proposed aerobic exercise program for 12 weeks. Results. The proposed aerobic sports program with vitamin D intake improved biochemical variables, such as total fat, total cholesterol, triglyceride, high-density cholesterol, low-density cholesterol, OH, and Vitamin D-025 for the sample under investigation. The application of the aerobic program with vitamin D led to weight loss among the study's female participants. The aerobic program with vitamin D intake has a positive effect on the general health status of the sample. Conclusions. Based on the study's findings, it is recommended to consider the positive effects of Vitamin D on the overall functional state of the body, making it essential to incorporate an aerobic sports program across various age groups. Regular medical tests are crucial for monitoring and maintaining overall health. Emphasizing the importance of regular exercise is vital in preventing weight gain and reducing the risk of certain chronic diseases. By implementing these recommendations, individuals can enhance their overall well-being and lead a healthier lifestyle. To further validate these outcomes, similar studies should be conducted on different age groups and diverse samples.
