After trauma to the low back, a decrease in intervertebral joint stiffness can occur, which can lead to inability of the motor-control system to compensate for the tasks imposed on the tissues, resulting in spinal instability. Intervertebral joint stiffness can be thought of as a tightening of a corset around a spine segment, facilitated through coactivation of small and large spinal muscles. The motor-control system might be able to adapt initially with cocontractions of the intrinsic muscles, but an unbalanced demand between the small and large muscles can lead to muscle fatigue and poor task performance. The inability of the …


Sight-Reading Versus Repertoire Performance On The Piano: A Case Study Using High-Speed Motion Analysis, Brenda Wristen, Sharon Evans, Nikolaos Stergiou Mar 2006

Sight-Reading Versus Repertoire Performance On The Piano: A Case Study Using High-Speed Motion Analysis, Brenda Wristen, Sharon Evans, Nikolaos Stergiou

Health and Kinesiology Faculty Publications

This study was intended to examine whether differences exist in the motions employed by pianists when they are sightreading versus performing repertoire and to determine whether these differences can be c[uantified using high-speed motion capture technology. A secondary question of interest was whether or not an improvement in the efficiency of motion could be observed between two sight-reading trials of the same musical excerpt. This case study employed one subject and a six-camera digital infrared camera system to capture the motion of the pianist playing two trials of a repertoire piece and two trials of a sight-reading excerpt. Angular displacements …


Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka Jun 2005

Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka

Young adults exhibit a longer time to task failure when performing a submaximal isometric contraction by pushing against a force transducer (force task) than when supporting an equivalent inertial load (position task). The purpose of this study was to compare the time to failure for old adults when they performed a force task and a position task with the elbow flexor muscles. Eighteen old adults (72 ± 4 years) performed the force and position tasks at 20% maximal voluntary contraction (MVC) force until task failure. The time to task failure was briefer for the position task (10.6 ± 6.1 min) …


Muscle Fatigue And The Mechanisms For Task Failure, Sandra K. Hunter, Jacques Duchateau, Roger M. Enoka Jan 2004

Muscle Fatigue And The Mechanisms For Task Failure, Sandra K. Hunter, Jacques Duchateau, Roger M. Enoka

Exercise Science Faculty Research and Publications

An alternative approach in the study of muscle fatigue is to address the question, “What causes task failure during a fatiguing contraction?” This approach is described by considering how variation in the type of load supported and contraction intensity influence both the time to task failure and the centrally mediated adjustments in reflex activity and motor unit behavior

Injuries to the ankle joint are among the most common of all sport-related injuries. Figures range from 10% to 30% of all injuries and from 5% to 20% of all time-loss injuries.1-9 Athletes participating in sports such as football, soccer, basketball, and volleyball are especially at risk for this type of injury, largely because of the running and jumping involved. In 1977, Garrick3 reported that during any single year of a 6-year period at the University of Washington, at least 16% of all time-loss injuries for all sports involved ankle sprains.
