Hamstring/quadriceps ratio: reading benchmarks
Why this ratio is tracked, and how to fold it into objective strength follow-up.

What it is
The hamstring/quadriceps ratio compares the strength of the knee flexors and extensors. It's a muscle-balance indicator, tracked notably around return to activity.
Reading the number
- A ratio is read over time and against the contralateral side.
- Left/right asymmetry is as telling as the absolute value.
Integrated measurement
With Kinvent integration, peak-force values flow automatically into the record: no double entry, and a usable history.
