Peak vertical ground reaction force during two-leg landing: a systematic review and mathematical modeling.

ABSTRACT:

Objectives

(1) To systematically review peak vertical ground reaction force (PvGRF) during two-leg drop landing from specific drop height (DH), (2) to construct a mathematical model describing correlations between PvGRF and DH, and (3) to analyze the effects of some factors on the pooled PvGRF regardless of DH.

Methods

A computerized bibliographical search was conducted to extract PvGRF data on a single foot when participants landed with both feet from various DHs. An innovative mathematical model was constructed to analyze effects of gender, landing type, shoes, ankle stabilizers, surface stiffness and sample frequency on PvGRF based on the pooled data.

Results

Pooled PvGRF and DH data of 26 articles showed that the square root function fits their relationship well.
