Emergency face-mask removal effectiveness: a comparison of traditional and nontraditional football helmet face-mask attachment systems.

Context: Football helmet face-mask attachment design changes might affect the effectiveness of face-mask removal.

Objective: To compare the efficiency of face-mask removal between newly designed and traditional football helmets.

Design: Controlled laboratory study.

Short and longer-term effects of creatine supplementation on exercise induced muscle damage.

The purpose of this investigation was to determine if creatine supplementation assisted with reducing the amount of exercise induced muscle damage and if creatine supplementation aided in recovery from exercise induced muscle damage. Two groups of subjects (group 1 = creatine; group 2 = placebo) participated in an eccentric exercise protocol following 7 and 30 days of creatine or placebo supplementation (20 g.d(-1) for 7 d followed by 6g.
