Study design
The intervention was a non-randomised controlled before-and-after trial. Wingate anaerobic test (WAnT) and Running-based Anaerobic Sprint Test (RAST) were used in an 8-week interval to estimate the anaerobic fitness level and its changes resulting from the training process in athletes and physical education classes in untrained individuals. The WAnT was conducted on a cycle ergometer under controlled laboratory conditions and the RAST was performed on a grass turf training field (Fig. Study design.
