Force Application Technique, Sprint Performance, and Training Implications

Athletics Coaching AI

This episode discusses a research paper examining the biomechanics of sprint running and how these factors affect performance in the 100m race. The study explores the importance of ground reaction force (GRF), particularly its horizontal component, in determining acceleration. The authors used a motorised instrumented treadmill to measure GRF in detail and found that the ability to orient GRF forward is crucial for sprint performance, even more so than the total force produced. The study also investigates how different levels of athletes, ranging from non-specialists to world-class performers, apply force differently during sprinting. The results highlight the need for training programs that focus on both physical strength and technical skill development, specifically in orienting force forward during acceleration.
