The positive effects of enhanced expectancies on motor performance and learning have been demonstrated by numerous studies. A more recent study by Stoate, Wulf, and Lewthwaite (2012) showed than enhancing one's expectancy by giving positive feedback increased movement efficiency and decreased oxygen consumption in experienced runners during a 20 minute running test at 75% of max oxygen consumption, compared to those who received no feedback. The purpose of the present study was to test if enhancing expectancies can improve movement efficiency (i.e., reduce oxygen consumption) during a sub-maximal exercise test. Participants were randomly assigned to one of two groups, enhanced …
The Clinical Usefulness Of Vector Coding Variability In Female Runners With And Without Patellofemoral Pain, Tommy Joseph Cunningham
The Clinical Usefulness Of Vector Coding Variability In Female Runners With And Without Patellofemoral Pain, Tommy Joseph Cunningham
Theses and Dissertations--Kinesiology and Health Promotion
It has been suggested that Patellofemoral Pain (PFP) may be the result of a coordinate state which exhibits less joint coordination variability. The ability to relate joint coordination variability to PFP pathology could have many clinical uses; however, evidence to support clinical application is lacking. Vector coding’s coupling angle variability (CAV) has been introduced as a possible analysis method to quantify joint coordination variability. The purpose of this study was to assess the clinical usefulness of CAV measures from a dynamical systems perspective. This involved establishing the precision limits of CAV measures when physiological conditions are held constant, altering control …
