Readers may be familiar with the Åstrand Test as devised by professor Per-Olof Åstrand, a pioneer in modern exercise physiology at the Swedish School of Sport and Health Sciences (GIH) in Stockholm. The six-minute submaximal cycle test is frequently used in occupational health services, rehabilitation centres and with elderly for estimating VO2 max. Based around the same principle and with modern technology, Monark Exercise is still the golden standard of ergometers for testing and training. The bikes can handle extreme loads and are the obvious choice amongst athletes with tough demands on their training and for researchers in sports medicine.
