Original research title: ‘Hip Strength as an Intrinsic Risk Factor for Lateral Ankle Sprains in Youth Soccer Players’ (De Ridder et al., 2016)

Authors: De Ridder, R; Witvrouw, E; Dolphens, M; Roosen, P; Van Ginckel, A

Year: 2016


Ankle sprains are one of the most common injuries in youth football, and account for approximately 20% of all injuries. While typically a minor injury, repeated ankle sprains can lead to chronic ankle instability or lower activity levels among youth athletes.

The purpose of this study was to investigate hip muscle strength as a risk factor for lateral ankle sprains in young football players over three seasons.

The study measured hip extensor strength using a handheld dynamometer.


Assessing hip extensor strength or weakness is advisable in preseason testing protocols to screen for ankle sprain risk.

Key Findings

Findings from the study suggest athletes with decreased hip extensor strength are at a greater risk to sustain a lateral ankle sprain.

No other variable in this study was identified as a risk factor.
