Higher ACL injury rates have been recorded in cleats with higher torsional resistance in American football, which warrants better understanding of shoe/stud-dependent joint kinetics. The purpose of this study was to determine differences in knee and ankle kinetics during single-leg land cuts and 180° cuts on synthetic infilled turf while wearing 3 types of shoes. Fourteen recreational football players performed single-leg land cuts and 180° cuts in nonstudded running shoes (RS) and in football shoes with natural (NTS) and synthetic turf studs (STS). Knee and ankle kinetic variables were analyzed with a 3 × 2 (shoe × movement) repeated-measures ANOVA (P < .05). A significant shoe-by-movement interaction was found in loading response peak knee adduction moments, with NTS producing smaller moments compared with both STS and RS only in 180° cuts. Reduced peak negative plantar flexor powers were also found in NTS compared with STS. The single-leg land cut produced greater loading response and push-off peak knee extensor moments, as well as peak negative and positive extensor and plantar flexor powers, but smaller loading peak knee adduction moments and push-off peak ankle eversion moments than 180° cuts. Overall, the STS and 180° cuts resulted in greater frontal plane knee loading and should be monitored for possible increased ACL injury risks.

The outdoor athletic fields of Sunshine State University are in poor condition. Overuse, insufficient drainage, and a lack of human and financial resources have contributed to the fields’ deterioration. Sunshine State University’s director of athletics, Emily Rodriguez, has decided to replace the existing fields, but that decision is just the tip of the iceberg. Rodriguez now must decide on a natural or synthetic surface for the new fields. This decision is complex because cost, maintenance, durability, player safety, and player preference must all be considered. Both surfaces have their advantages and disadvantages. In the end, Rodriguez must decide which surface is right for Sunshine State University.

-bodied-youth sport, except in impoverished environments, are the need for sport and equipment adaptations ( Castañeda & Sherrill, 1999 ). Challenger baseball leagues for special-population youth are excellent examples of how baseball can be effectively adapted. For instance, the fields have to be made of synthetic
