Bilateral: Flight ratio, ground contact time, ground reaction force, impact, braking, footstrike, pronation excursion, pronation velocity

Hip/pelvis: Pelvic drop, pelvic tilt, pelvic rotation

Extra: Muscle sEMG (upper leg)

During strength training

Muscle sEMG, force, velocity, power

Where we work

Runfisx helped me understand my running using remote gait analysis. The insights I gained were extremely valuable and allowed me to understand why I had been getting injured and how to address the issues for the future. I'm very grateful for the help and looking forward to pain free running!
