Sprint Technique Profiles
Beyond raw speed. Decode the biomechanical efficiency of the world's fastest athletes using computer vision and movement science.
The Science of Sprinting
Sprint performance is the product of two main variables: Stride Length and Stride Frequency. However, the true differentiator for elite athletes is efficiency—how effectively they apply force into the ground. SpeedTrackr uses computer vision to analyze your posture and mechanics, generating a Technique Score based on professional biomechanical models.
Ground Contact Time (GCT)
One of the most critical metrics in our profiles is Ground Contact Time. This is the duration your foot is in contact with the track during a single stride. Top-tier sprinters like Usain Bolt or Noah Lyles minimize GCT (often below 0.090s at max velocity) to maximize flight time and reduce energy leakage. Our AI extracts this data from standard 60fps or 120fps video with high precision.

Shin Angle in Sprinting: Why It Matters for Speed
Shin angle is one of those sprint coaching cues that sounds almost too simple. But behind that simple phrase is a big reason why some athletes explode while others look like they're working hard but not going anywhere.

What Your Ankle Is Telling You About Your Sprint Speed
If you want to sprint faster, you don’t need to start by obsessing over your knees or hips. Start lower. Your ankle is the last big 'translator' between your body and the ground.
