Viscoelastic properties of lower extremity muscles after elite track cycling sprint events: A case report

Abstract

Sprint cycling events require a high level of anaerobic capacity and, therefore, may affect peripheral fatigue throughout exercise-induced muscle damage. In fact, those alterations might decrease power generation. This study was performed on a 23 years old male elite track cyclist taking part in a sprint event. The measurements included power output (W) and cadence (rpm), lactate concentration (La-), heart rate (bpm), Rating of Perceived Exertion scale and viscoelastic properties analysis. The present study has shown a new approach to monitor the muscle properties of the lower extremity after 200 m flying start and repeated sprint races. Therefore, we hypothesized that repeated sprint races might lead to alterations in viscoelastic properties of lower extremity muscles. In track cycling, especially in sprint events, these variations may lead to increased muscle fatigue. Furthermore, training control and monitoring related to the assessment of muscles properties can be a source of counteracting injuries and relieving fatigue.
