Inside An Olympic Sprint Coach's Hamstring Testing Protocol

Physiotherapist and Olympic sprint coach John Nicolosi breaks down how he actually tests, loads and clears hamstring injuries, from the first days after a strain through to full return to sprint. No fluff, just the framework he uses every day at Melbourne Athletic Development.

In this session, John covers:

• The three-part framework behind every hamstring injury: tissue properties, biomechanics, and an athlete's capacity to handle load
• Why rate of force development matters more than peak force alone, and the benchmark he tests athletes against
• How he loads hamstrings early (including assisted Nordics and blood flow restriction) to get athletes back faster than typical timelines
• The biomechanics of hamstring strain: pelvis position, terminal swing, and what to look for on video
• The exact criteria he won't compromise on before clearing an athlete to sprint or compete again
