Injury data collection and utilisation practices in university sports teams: A cross-sectional study.

Objectives: This study aimed to examine injury surveillance practices in a variety of university sports teams and barriers and facilitators for injury data collection and utilisation.

Design: Cross-sectional study.

Setting: University sports teams in Japan.

Sports Injury Surveillance Systems and Guidelines in Japan: A Systematic Review.

This systematic review aimed to identify sports injury surveillance systems (ISSs) and injury surveillance guidelines (ISGs) developed and currently used in Japan. Additionally, the extent to which ISSs and ISGs developed overseas are employed in Japan was also examined. A systematic search of electronic databases was performed in March 2021.

A Biomechanical Comparison Among Three Kinds of Rebound-Type Jumps in Female Collegiate Athletes.

Background: Single-legged drop jumps (SDJ), single-legged repetitive jumps (SRJ), and single-legged side hops (SSH) are often used as plyometric training and functional performance tests. Differences in the kinetics and kinematic characteristics of lower extremity joints during these jumps are unclear.

Hypothesis/purpose: The purpose of this study was to investigate the joint motion and mechanical work of the takeoff leg from foot contact to foot-off during SDJ, SRJ, and SSH in the sagittal and frontal planes in female athletes.

Effects of friction massage of the popliteal fossa on dynamic changes in muscle oxygenation and ankle flexibility.

[Purpose] This study aimed to examine whether or not friction massage of the popliteal fossa would be effective for achieving dynamic changes in muscle oxygenation and ankle flexibility. [Subjects and Methods] Twelve healthy male university students participated. Before and after friction massage, dynamic changes in muscle oxygenation and ankle flexibility were measured by near-infrared spectroscopy to evaluate its efficacy.
