Athletes with stronger and longer (fascicle length) hamstrings show more efficient, front-side mechanics, greater hip flexion, faster knee extension, and less anterior pelvic tilt (Ripley et al. 2025) Those with weaker or shorter hamstrings tend to display back-side mechanics,


greater pelvic tilt, higher biceps femoris activation, and slower limb velocity. This study reinforces how hamstring strength and architecture directly shape running form and how limitations in those qualities can alter mechanics that influence both performance and injury risk.

I dive deep into this connection in Speed Kills, from how to build eccentric and isometric strength, to developing relative strength, layering plyos and sprint drills, and structuring fitness so it all fits together. Link below
