respective events. The IAAF World Cross Country Championships in 2015 (Guiyang, China; elevation 1,275 m) and 2017 (Kampala, Uganda; elevation 1,210 m) were held at altitudes high enough to significantly impair aerobic performance. In the consensus statement, we will briefly discuss the physiological effects

For some elite endurance athletes, major races are held at altitude. 1 , 2 Competing even at low altitudes, classified as 500 to 2000 m, 3 can affect performances. 4 For instance, the International Association of Athletics Federations classifies events held at any elevation >1000 m as being

also linked to the fact that it was the very first event to be organized in a city located at altitude, which raised several concerns. Indeed, these Games witnessed an unprecedented level of supervision and medical monitoring of the participating athletes that was aimed at preserving their health and

To find the optimal altitude for each sporting event, it is important to know the effect of altitude on the main variables that determine performance. The main performance-determining variables, according to the model of Joyner and Coyle, 1 are performance oxygen uptake ( V ˙ O 2 ; determined by

the mechanical power output (and thus training quality). 8 As such, it is common practice for current RSH approaches to utilize moderate simulated altitudes (F I O 2  = 0.135–0.145). 4 However, the majority of this research has been conducted in temperate ambient conditions, raising the question as

Many high-intensity, intermittent team sports undertake prolonged preseason training, which is important for developing physical capacities essential for competitive success. Environmental stimuli, such as altitude 1 or heat, 2 have been applied during these periods, in an attempt to enhance

Historically, altitude training has been used only by endurance athletes for performance enhancement after return to sea level and/or in preparation for heavy training blocks at sea level. Recent innovative “live low—train high” methods are now well established for improving repeated-sprint ability

The influence of these variables on physical activity may be direct or indirect. Associations may also be modified by other variables such as gender. A direct effect of air temperature

For many endurance athletes, altitude training is a key component of their preparation for major competitions. 1 According to the classical or live high:train high (LHTH) altitude-training model, athletes travel to venues of increased elevation to live and train for 2 to 4 weeks, in preparation
