Comparison of on-ice and off-ice graded exercise testing in collegiate hockey players.

The purpose of this study was to compare lactate thresholds (LT) and maximal aerobic capacities (VO(2 max) during sport-specific skating (on ice) and cycle ergometry (off ice) in collegiate hockey players. We hypothesized that VO(2 max) and LT would be higher on ice. We also sought to determine if on-ice and off-ice VO(2 max) values were correlated.

Traumatic anterior cruciate ligament tear and its implications on meniscal degradation: a preliminary novel lapine osteoarthritis model.

Background: Injury patterns of the meniscus following impact trauma resulting in anterior cruciate ligament (ACL) rupture are not well understood. This study explored the spatial and temporal distribution of meniscal tears in a novel in vivo lapine model.

Methods: Skeletally mature Flemish Giant rabbits were subjected to either tibiofemoral impaction resulting in ACL rupture or surgical ACL transection.

Sport-specific assessment of lactate threshold and aerobic capacity throughout a collegiate hockey season.

The purpose of this study was to examine lactate threshold (LT) and maximal aerobic capacity with a sport-specific skating protocol throughout a competitive season in collegiate hockey players. We hypothesized that maximal aerobic capacity and skating velocity at LT would increase as the season progressed. Sixteen Division I college hockey players performed a graded exercise skating protocol to fatigue at 3 different times (pre-, mid-, and postseason).

Gender differences in hockey players during on-ice graded exercise.

The purpose of this study was to examine whether gender differences exist for ventilatory threshold (VT), lactate threshold (LT), and Vo2max during on-ice skating in college hockey players. Ten male and 10 female Division III college hockey players performed a graded exercise skating protocol until reaching volitional fatigue. The graded exercise test employed stages that were 80 seconds in duration, with 40 seconds of rest between each stage to obtain blood lactate samples.

Core stability measures as risk factors for lower extremity injury in athletes.

Introduction/purpose: Decreased lumbo-pelvic (or core) stability has been suggested to contribute to the etiology of lower extremity injuries, particularly in females. This prospective study compares core stability measures between genders and between athletes who reported an injury during their season versus those who did not. Finally, we looked for one or a combination of these strength measures that could be used to identify athletes at risk for lower extremity injury.

Arthroscopically assisted reduction and fixation of a juvenile Tillaux fracture.

This is the first report of arthroscopically assisted reduction and fixation of a juvenile Tillaux fracture. Arthroscopic visualization assisted with the anatomic reduction of the articular fragment. This adds arthroscopy as a modality available to help obtain accurate reduction as well as understand the nature of the fracture pattern in juvenile Tillaux fractures along with its adult counterpart and other intra-articular fractures.
