What is the hamstring to quadriceps ratio?

The H:Q ratio compares hamstring strength to quadriceps strength in the same leg. The conventional ratio (both concentric) should be at or above 0.6. The functional ratio (hamstring eccentric vs quad concentric) should be at or above 1.0.

What H:Q ratio indicates injury risk?

A conventional H:Q ratio below 0.6 is associated with increased hamstring strain risk. Asymmetry between legs greater than 15% also predicts injury regardless of absolute ratio.

How is eccentric strength measured?

Eccentric strength is typically measured on an isokinetic dynamometer. The Nordic hamstring curl test provides a field measure of eccentric hamstring strength capacity.

Eccentric to Concentric Strength Ratio and Injury Risk

Calculate eccentric to concentric strength ratio for injury risk assessment. Hamstring to quad ratio below 0.6 indicates elevated hamstring injury risk.
