Chronic Training Load And Dorsiflexion Range Of Motion Throughout A Season In Professional American Soccer, Tristan L. Young

Electronic Theses and Dissertations

Soccer has an incredibly complex movement profile. Players experience various types of strains on their body from the requirement to land in awkward positions while maintaining the ability to quickly accelerate and decelerate. Dorsiflexion range of motion (DFROM) is of concern due to the movement profile and ball control that requires constant eccentric and concentric actions at the talocrural joint. With an American soccer season spanning across nine months these demands can contribute to overuse, which has been linked to restricted range of motion. Restricted DFROM and asymmetries have been identified as injury predictors, but their relationship to performance has …

Quantification Of Eccentric Load Using Accelerometer Imbedded In Gps, Chow Chea Yeo

Theses: Doctorates and Masters

Global positioning system (GPS) with a triaxial accelerometer is widely used to monitor movements of athletes in games and training, and “body load” (BL) representing the accumulation of the rate of changes in three planes of movements is obtained to determine the training load of a session. Deceleration, change of directions and stopping require eccentric contractions of leg muscles, potentially causing muscle damage and affecting athletic performance. Thus, it is important to monitor eccentric loading in games and training. A variable known as “eccentric index” (EI) purports to be a better representation of eccentric loading than BL. However, it is …
