Sažetak
The aim of this study was to evaluate the effects of eccentric exercise on anaerobic power, starting speed and anaerobic endurance. The participants performed the maximum cycling sprint test (MCST) prior to
eccentric exercise (ECC), 10 minutes after, as well as one hour, 24 hours, 48 hours, and one week after ECC. The peak and mean power, time to attain peak power, time of maintaining peak power and power decrease were measured in the MCST. Before and after ECC, the myoglobin concentration (Mb) in the blood plasma was measured. After ECC, a significant (p<.05) increase in Mb was observed. A significant (p<.05) decrease was noted in peak (-.92±0.42 W.kg-1) as well as in mean power (-.57±0.36 W.kg-1) immediately after ECC. A significant (p<.05) decrement of these indicators lasted for at least 24 hours after ECC. Eccentric exercise did not affect starting speed (time to attain peak power) and anaerobic endurance (time of maintaining peak
power and power decrease during MCST).
