Endurance testing has a long tradition in the Swiss Orienteering Federation. It has become an important tool in monitoring effectiveness of training and in assessing endurance performance. The vast majority of athletes and coaches indicate that sport science is meaningful and endurance testing is of high informative value for them. Endurance testing is regularly done in the lab, but also field tests are carried out each year. They particularly empower and support athletes in their specific preparation for important competitions. Also in the future new competition formats can be prepared and training may be monitored by a new format of specific tests. In various endurance sports physiological demands may be similar.
