Low Frequency Fatigue In Human Quadriceps Is Fatigue Dependent And Not Task Dependent, Masaki Iguchi, Kris Baldwin, Charles Boeyink, Carol Engle, Michael Kehoe, Anish Ganju, Andrew J. Meszaros, Richard Shields

Faculty Publications - College of Physical Therapy

It is well accepted that a low intensity/long duration isometric contraction induces more low frequency fatigue (LFF) compared to a high-intensity/short-duration contraction. However, previous reports examined the intensity/duration of the contraction but did not control the level of fatigue when concluding fatigue is task dependent. The purpose of this study was to determine whether a long duration/low intensity fatiguing contraction would induce greater LFF than a short duration/high-intensity contraction when the quadriceps muscle was fatigued to similar levels. Eighteen healthy male subjects performed quadriceps contractions sustained at 35% and 65% of maximal voluntary contraction (MVC) on separate days, until the …

In-Season Functional Shoulder Training For High School Baseball Pitchers, Jason Brumitt, Erik Meira, Greg Davidson

Faculty Publications - College of Physical Therapy

The overhead throwing motion is used in numerous sports including track, football, and baseball. Among these sports, the baseball pitch is unique in the demands placed upon the shoulder. The forces created in the shoulder can potentially lead to pathology affecting the athlete's career. To enhance performance and decrease the risk of injury, it is important that the athlete participate in a year-round periodized program. Inappropriate or deficient training combined with the stress that the shoulder experiences during a season can lead to strains, impingement, tendon or labral tears, and instabilities.
