EFFECTS OF SPRINT INTERVAL TRAINING ON ATHLETES' SPEED

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