The effect of using competitive training combined with vitamin D3 on developing the speed-specific strength of intermediate-level futsal players

Abstract

Futsal has witnessed significant development in physical performance and the speed of gameplay, making it one of the most physically demanding sports. To maximize the benefits of training and improve performance, competitive drills have become an essential part of players' training programs. This research aims to improve the speed-strength qualities of players through advanced training methods supported by nutritional supplements. Speed-strength is a critical element for futsal players as it helps them move faster on the field and perform tasks with higher efficiency. The importance of this research lies in designing competitive drills specifically aimed at improving this quality, as well as studying the effects of Vitamin D3 supplements on physical performance. Vitamin D3 enhances muscle and bone health, enabling players to endure intense physical effort and achieve better performance during matches.The goal of this research is to design competitive drills that target improving speed-strength qualities in futsal players, as well as studying the impact of Vitamin D3 on physical performance. The research will measure the effects of these drills on biochemical variables such as Vitamin D3 levels in the body, aiming to enhance endurance and improve players' performance in matches.
