EFFECTS OF SPRINT INTERVAL TRAINING ON ATHLETES' SPEED

Abstract

Introduction: The sprint is a track and field event that combines strength and speed. It has a cyclical nature. Each muscle group involved in the starter completes hundreds of contractions. Maximum strength and the fastest muscle contraction are the best combinations. This is the explosive power of runners. Objective: Analyze the effects of sprint interval training on the speed of track and field athletes. Methods: In a random sampling, 30 college athletes were selected for the investigation. These runners were divided into experimental and control groups. The experimental group adopted the sprint interval training method with tire traction. The control group did not engage in this physical exercise. The speed training load of the athlete was gradually increased during the experimental period, lasting 10 weeks. Competitors performed short-distance tests after the physical training. Results: After ten weeks, the experimental group's performance on 30 meters was significantly improved (P<0.05). There was a statistical increase in acceleration in the 50m start (P<0.01). There was no significant difference between the experimental and control groups in the 30-meter starting speed (P>0.05). The experimental group significantly improved the 50m performance (P<0.05). Conclusion: Sprint interval training is effective in increasing the speed of athletes.
