Comparison of lower body specific resistance training on the hamstring to quadriceps strength ratios in men and women.

In this study, we compared hamstring (H) and quadriceps (Q) strength changes in men and women, as well as changes in conventional and functional H:Q ratios following an identical 12-week resistance training program. An isokinetic dynamometer was used to assess 14 male and 14 female participants before and after the intervention, and conventional and functional H:Q ratios were calculated. Hamstring strength improved similarly in men and women, but improvement in quadriceps strength was significantly greater in men, while women showed only modest improvements.

Comparison of longitudinal biomechanical adaptation to shoe degradation between the dominant and non-dominant legs during running.

This study compared the biomechanical adaptation to running shoe degradation between the dominant (D) and non-dominant (ND) leg. Twenty-four runners performed a pre-test in the laboratory, completed 200 miles of road running in a pair of assigned shoes and then returned for a post-test. Kinetic and kinematic data of running in new and worn shoes were collected.

Correlation of three different knee joint position sense measures.

Objective: The purpose of this study was to investigate correlation during concurrent measurement among three knee joint position sense (JPS) measures in sitting position and between two measures in standing position.

Methods: Isokinetic dynamometer, electrogoniometer, and two dimensional (2D) video analysis were used for measuring knee JPS. The JPS was measured both in sitting and standing positions.

A comparison of knee joint laxity among male and female collegiate soccer players and non-athletes.

Female athletes are at least twice as likely to sustain an anterior cruciate ligament injury than male athletes. The underlying cause of ACL injury is multifactorial. However, several researchers have identified knee joint laxity as a possible contributing factor.
