PhD defence - Casper Skovgaard

Casper Skovgaard is defending his PhD thesis

Intense training as a means to improve running performance in trained runners and the adaption of muscle tissue

The intense exercise response as well as the effect of 40 and 120 days of low-frequency intense training, 40 days of high-frequency intense training, tapering and repeated intense training interventions.

About the thesis

A 6-wk intense training period consisting of speed endurance training (repeated 30-s all-out running) and a reduced volume of endurance training, induce specific adaptations in type I and type IIa muscle fibers that may explain improved running economy and running performance in trained runners. A prolonged period (18-wk) of intense training as well as a period with increased intense training frequency leads to further improved short-term performance (<6 min) and maintained 10-km performance. Tapering, i.e. reduced training volume, improves short-term performance even further. A second 6-wk intense training period, after a period of habitual training, has a greater impact on short-term performance than the first intervention, while the gain in 10-km performance is of the same magnitude.

Collectively, these findings indicate that short-term performance does continuously improve with different compositions of intense training and that the gain in 10-km performance, which is associated with improved running economy, is obtained relatively swiftly. This, as well as the physiological adaptations and relevance of intense training is discussed.
