Differences Between The Sexes In Knee Kinetics During Landing From Volleyball Block Jumps, Gerwyn Hughes, James Watkins, Nick Owen

Kinesiology (Formerly Exercise and Sport Science)

The purpose of the study was to investigate gender differences in frontal and sagittal plane kinetics (normalized ground reaction force and normalized knee moment) in university volleyball players when performing opposed block jump landings. Females displayed a significantly lesser normalized knee extension moment at the start of muscle latency than males. The greater normalized knee extension moment at the start of muscle latency in females suggests that through practice, the female subjects may have developed a landing strategy that minimizes the moment acting about the knee in the sagittal plane to reduce the likely strain on the passive support structures. …
