Correlation between a new aerobic fitness shuttle test and YoYo-intermittent recovery level 1. A preliminary research

Trainers are always looking for methods low cost, noninvasive\r\nand of short duration to assess physical fitness. In this preliminary\r\nstudy, data suggest the use of this IST to assess the aerobic\r\nfitness in young soccer players. For practical purposes the shorter\r\nduration and lower intensity should involve both trained and\r\nuntrained players and become a useful tool for the trainer. Obviously\r\nmore research is needed to better define this new IST.
