I'm a Phd Researcher focusing in the altitude training in sport. I'm a Msc in Exercise physiology that would like to assess the real use of the altitude training in the cyclist population (professional and amateur). Until the data I have about 150 answers of a questionnaire of this topic. However, to obtain a important result of the study we need 200 answers as less. Please If you know people that could collaborate or yourself, please entry at: askingaltitude.blogspot.com.es or in the following link: docs.google.comeditOpen ↗
