ReviewAccidental hypothermia in recreational activities in the mountains: A narrative review.
The popularity of recreational activities in the mountains worldwide has led to an increase in the total number of persons exposed to cold and extreme environments through recreation. There is little conclusive evidence about the risk of hypothermia for specific activities or populations, nor is it clear which activities are represented in the literature. This is a non-systematic review of accidental hypothermia in different recreational activities in the mountains, with a specific focus on outdoor or winter activities that potentially involve cold exposure. ⋯ Hypothermia in skiers, snowboarders, and glacier-based activities is most often associated with accidents occurring off-piste or in the backcountry (crevasse, avalanche). Organizers of outdoor events also have a role in reducing the incidence of hypothermia through medical screening and other preparedness measures. More complete collection and reporting of data on mild hypothermia and temperature measurement would improve our understanding of the incidence of hypothermia in outdoor recreation in future.

An experiment on the impact of coaches' and athlete leaders' competence support on athletes' motivation and performance.
Grounded in the Cognitive Evaluation Theory, the present experiment aimed to compare the relative impact of competence support provided by coaches versus athlete leaders on players' competence satisfaction, intrinsic motivation, and performance. ⋯ Our findings highlight the importance of providing competence support to enhance team performance. Given athlete leaders' unique impact on teammates' competence satisfaction and motivation, instructing athlete leaders how to provide competence support constitutes an important motivational pathway for coaches to optimize team functioning.
