Assessing sprint technique - does it even matter? with Johan Lahti

Pacey Performance Podcast

In this episode of the Pacey Performance Podcast, Johan Lahti discusses the complexities of assessing sprint technique in relation to hamstring injury risk. While technology has made sprint assessment more accessible, measuring its impact on injury risk remains challenging, and Johan questions whether it's always worth the effort. However, he emphasizes the importance of focusing on key aspects of technique, such as minimizing time under tension and analyzing movement patterns like overstriding or increased hip flexion, which can lead to hamstring issues.

Johan highlights that sprint assessments should consider the entire movement cycle, as isolated 2D assessments may miss critical factors like pelvic movement. He notes that technique assessments do not always predict performance or injury risk accurately, stressing the need to address both movement patterns and physical strength. Strengthening key muscle groups, especially the glutes and hamstrings, is vital for maintaining sprint technique, particularly under fatigue, which can help reduce injury risk.

He also discusses the rising prevalence of hamstring injuries due to increased high-speed sprinting in professional sports. He advocates for teaching sustainable sprint techniques to young athletes to develop overall athleticism and prevent future injuries. Force-velocity profiling is also mentioned as a valuable tool for identifying athletes' strengths and weaknesses in sprinting.

While assessing sprint technique is valuable, it must be done holistically and integrated with strength training to minimize hamstring injury risk and improve performance.

Main talking points:

• Focus on key aspects of sprint technique
• Minimize time under tension during sprinting
• Analyze entire movement cycle for injury risk
• Address overstriding and increased hip flexion
• Assess sprint technique in a fatigued states
• Teach sustainable sprint techniques to young athletes
• Develop strength and movement variability early
• Train sprint form to reduce hamstring strain
• Incorporate sprint assessments with strength training
