Long Distance Capacities Of Amerindians

Joyner et al. (4) analyze the main factors contributing to the improvement in marathon races emphasizing V̇o2max, lactate threshold, and running economy (RE). We consider it important to foreground the role of high altitude. There is evidence that four weeks of training periods at simulated 2,000–3,100 m can decrease the V̇o2 for a given velocity (5). Also, there are interesting investigations not only in African but also in Amerindian athletes.
