Abstract EN
Cross-country running is becoming an increasingly popular sport, with a significant participation noted at the high school level.
The aim of this study was to compare gender and bilateral hip extension range of motion and hip and knee extension strength of high school cross-country runners.
31 participants volunteered from a local high school cross-country team (16 males and 15 females).
The modified Thomas test was utilized to measure hip extension range of motion bilaterally using a digital inclinometer.
In order to measure hip and knee isometric strengths, an isokinetic dynamometer was employed.
A mixed model approach revealed a statistically significant difference in peak hip extension strength between genders but not the side.
Male athletes demonstrated a 29.2 Nm/kg (P<0.05) greater force production than females during isometric hip extension strength testing.
There were no significant differences in peak knee extension isometric strength, hip extension range of motion, and the ratio of peak hip and knee strength between genders and the dominant and nondominant leg.
Female cross-country runners should focus on increasing hip extension strength to help maintain hip stability during running.
This may be beneficial in decreasing the chances of experiencing patellofemoral pain in long-distance runners.
