BACKGROUND: Paralympic sports provide opportunities for those who have an impairment that might otherwise be a barrier to participation in regular sporting competition. Rifle shooting represents an ideal sport for persons with vision impairment (VI) because the direction of the rifle can be guided by auditory information when vision is impaired. However, it is unknown whether those with some remaining vision when shooting with auditory guidance would be at an advantage when compared with those with no vision at all...

REVIEW
Hans Hoppeler
Over the last 20 years a number of studies have been published using progressive eccentric exercise protocols on motorized ergometers or similar devices that allow for controlled application of eccentric loads. Exercise protocols ramp eccentric loads over an initial 3 weeks period in order to prevent muscle damage and delayed onset muscle soreness. Final training loads reach 400-500 W in rehabilitative settings and over 1200 W in elite athletes. Training is typically carried out three times per week for durations of 20-30 min...

#16
REVIEW
Thierry Paillard
This review addresses the possible structural and functional adaptations of the postural function to motor experience. Evidence suggests that postural performance and strategy evolve after training in inactive subjects. In trained subjects, postural adaptations could also occur, since elite athletes exhibit better postural performance than, and different postural strategy to sub-elite athletes. The postural adaptations induced are specific to the context in which the physical activity is practiced. They appear to be so specific that there would be no or only a very slight effect of transfer to non-experienced motor tasks (apart from in subjects presenting low initial levels of postural performance, such as aged subjects)...

REVIEW
Jeff M Coppage, Michelle G Carlson
Return-to-play (RTP) decisions often represent a challenge to physicians caring for athletes. The multifaceted and unique nature of each RTP decision makes standardization of the decision-making process impossible and demands of the physician thoughtful consideration of all competing interests and variables. Such difficult medical decisions are further complicated by unique ethical and legal considerations. Although no concrete RTP recommendations are available, the consensus of experienced team physicians and knowledge of the rules and regulations that apply to RTP are helpful guides to treating the various upper extremity injuries that occur in elite athletes...
