Effect of a four-week isocaloric ketogenic diet on physical performance at very high-altitude: a pilot study.

Background: A ketogenic diet (KD) reduces daily carbohydrates (CHOs) ingestion by replacing most calories with fat. KD is of increasing interest among athletes because it may increase their maximal oxygen uptake (VOmax), the principal performance limitation at high-altitudes (1500-3500 m). We examined the tolerance of a 4-week isocaloric KD (ICKD) under simulated hypoxia and the possibility of evaluating ICKD performance benefits with a maximal graded exercise bike test under hypoxia and collected data on the effect of the diet on performance markers and arterial blood gases.

Context of injury prevention strategies in Swiss basketball: survey of athletes, medical staff and coaches.

Objectives: This project aims to assess opinions, attitudes, knowledge, beliefs, practices and perceived barriers and facilitators of injury prevention (IP) strategies in Swiss basketball teams.

Methods: An online survey was sent to athletes, coaches and medical staff of the three best basketball leagues in Switzerland. The survey was subdivided in four sections: (1) characteristic of participants, (2) knowledge, opinions, attitudes and beliefs, (3) practices and (4) barriers and facilitators.
