Summary

This summary is machine-generated.

Males exhibit distinct lower extremity biomechanics during overhead squats compared to females, potentially explaining injury disparities. Sex-specific injury prevention programs are recommended to address these differences.

Area of Science:

Biomechanics
Sports Medicine
Orthopedics

Background:

Significant disparities exist in lower extremity injury rates between males and females.
High-risk biomechanical patterns in females are hypothesized to contribute to these disparities.
Limited research exists on sex-based biomechanical differences during overhead squats.

Purpose of the Study:

To compare lower extremity biomechanics and ranges of motion during the overhead squat between males and females.
To identify potential biomechanical factors contributing to sex-based injury disparities.

Main Methods:

Utilized an electromagnetic motion tracking system and force platform to quantify kinematics and kinetics during the squat descent.
Assessed range of motion using a standard goniometer.
Employed t tests to identify significant differences between male and female participants.

Main Results:

Males demonstrated greater peak knee valgus angle, hip flexion, vertical ground reaction forces, and hip extension moments.
Males exhibited less active ankle dorsiflexion (knee extended) and hip internal/external rotation compared to females.
No other significant biomechanical or range of motion differences were observed.

Conclusions:

Observed biomechanical differences in overhead squats between sexes may stem from variations in lower extremity range of motion.
Development of sex-specific injury prevention programs is crucial for improving biomechanics and range of motion in athletes.
