AbstractThe purpose of this study was to evaluate the specificity of the hexagonal obstacle test (HEX) as a measure of anaerobic endurance for Alpine skiers. Subjects were varsity Alpine skiers (AS, n = 10), varsity athletes (VA, n = 10) and physical education students (PES, n = 15). The VA and PES had no skiing experience. All subjects performed a 30‐s Wingate test (WIN), a treadmill anaerobic run (TM) and the HEX test. The AS and PES also performed 6 trials of the HEX and examination of these results revealed that the test had high reliability (intraclass r = .96), despite a significant(P.05) with those obtained on the WIN (r =‐.02) and on the TM (r =‐.33). There were significant differences(P<0.05) between the VA and the PES on the WIN (10.26±.38 vs. 8.71±.19 watts/kg, X±S.E.M.) and on the TM (61.5±4.8 vs. 47.9±3.1 s). No other comparisons were significant. Although a popular field test for skiers, it appears that the HEX is non‐specific and is not an appropriate test to measure anaerobic endurance of Alpine skiers.

摘要:

Cerebral concussion is an entity common primarily to collision and contact sports, but which can occur in any environment. The mechanisms of injury can include direct trauma, rotational, acceleration/deceleration forces, forces transmitted to the head as a result of force to another part of the body or through a series of blows. Subsequent classifications include Grade I (mild). Grade II (moderate) and Grade III (severe). Although the primary designating factors include the effect on consciousness and memory, the evaluator must be aware of additional signs and the potential for a deteriorating condition due to hemorrhage. A review of common injury mechanisms, signs, symptoms, evaluation process, grading, emergency care, and guidelines for return to participation and injury prevention are presented.
