Effect of four weeks of high intensity interval training and vitamin D۳ supplementation on physical fitness and performance of young boy futsal player

It has recently been studied by researchers in performing HIIT resistance training and is developing as an effective method among athletes and coaches. On the other hand, high-intensity intermittent resistance training as well as taking vitamin D supplements are common among athletes in various disciplines. However, the synergistic effects of vitamin D intake and intense periodic resistance training in futsal players have not been studied.A total of ۲۰ adolescents in the Khorasan Razavi Futsal Premier League were selected as a statistical sample, who were randomly divided into two groups of training and placebo (۱۰ people) and training and vitamin D supplementation (۱۰ people). After pre-test measurements, both groups performed the research protocol for ۴ weeks and ۳ sessions per week. At the end of ۴ weeks, all similar pre-test measurements were repeated in the post-test phase. The training protocol was that after warming up, the subjects performed two sets of ۲۰-second movements of Samoskat, Swing, Clean and Press and Samoddlift with a break of ۱۰ seconds between each set to perform kettlebell exercises, respectively. Exercises were performed ۳ times with a total time of ۱۲ minutes, ۳ sessions per week for ۴ weeks. The supplement group received vitamin D۳ capsules at a dose of ۴,۰۰۰ units per day with lunch.The results showed that there was no significant difference between the two groups in values of VO۲max, agility, ۱۰ m sprint record, ۳۰ m sprint record and explosive power (p >۰.۰۵). The results showed that a significant difference in fat percentage was observed between the two groups (p< ۰.۰۵).In general, it can be said that taking vitamin D۳ supplements along with resistance training in adolescent futsal players, although significantly reduced the percentage of fat, however, did not increase physical fitness and improve their performance.
