Student-Faculty Research - College of Physical Therapy

Patellar tendinopathy (PT) occurs in approximately 40% of elite jumping athletes. Players will typically play through the pain; however, if the condition is not successfully treated some are forced to retire from sport. Research has shown that there are no signs of chemical inflammation in the tendon, but rather the presence of a degenerative tendon with collagen disorientation and disorganization.

How Much Protein Can The Body Use In A Single Meal For Muscle-Building? Implications For Daily Protein Distribution, Brad Jon Schoenfeld, Alan Albert Aragon

Publications and Research

Controversy exists about the maximum amount of protein that can be utilized for lean tissue-building purposes in a single meal for those involved in regimented resistance training. It has been proposed that muscle protein synthesis is maximized in young adults with an intake of ~ 20–25 g of a high-quality protein; anything above this amount is believed to be oxidized for energy or transaminated to form urea and other organic acids. However, these findings are specific to the provision of fast-digesting proteins without the addition of other macronutrients. Consumption of slower-acting protein sources, particularly when consumed in combination with other …

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: There is a higher risk of post-concussion syndrome among minor athletes. This has resulted in The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), which is currently the primary test for collegiate and high school athletes for concussion assessment and return to play. Previous work from our lab has indicated a significant detection of cognitive deficit with a battery of cognitive testing including the Test of Variables of Attention (TOVA) and dual task testing incorporating balance testing along with the Stroop and number recall. In the previous findings these tests identified cognitive decline including reaction time and fine motor deficiencies …

Delayed Onset Muscle Soreness Attenuation By Acute Consumption Of Essential Amino Acids, Andi Johnson, Klaudia Szych, Ariel Gomez, Shannon Jackson, Annajita A. Rubio, Sarah A. Massey, Abraham Gomez, Lorenzo Juarez, Matthew A. Barlow 5622543

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: Essential amino acids have been known to be necessary for protein nutrition whether they are obtained by eating proteins or by a formula of the essential amino acids. Studies have consistently demonstrated the acute benefits of protein supplementation on post-exercise muscle anabolism, which may facilitate the recovery of muscle function and performance. However, when protein supplements have been provided in research studies, acute changes in post-exercise protein synthesis and anabolic intracellular signaling have not resulted in measureable reductions in muscle damage and enhanced recovery of muscle function. PURPOSE: The aim of this study is to implement a specific content …

Assessment Of Multiple Concussive Athletes With Dual Task Triple Stroop And Aerobic Exercise, Sierra Duran, Sarah A. Massey, Ariel Gomez, Matthew A. Barlow 5622543

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: Athletic concussion testing has mostly recently relied on a sedentary computer neurocognitive test battery called the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Previous tests directly compare baseline with post-concussion analysis of patient in regards to different cognitive aspects including; working memory, processing speed, and response time. No physical tests are included in the ImPACT analysis for return-to-play action. PURPOSE: In previous studies from our lab in these populations we concluded that the combination of a physical neural impediment with cognitive tests (dual-task with balance impairment) created a greater degree of impairment not observed in the sedentary ImPACT test. …

Effects Of Acute Low-Intensity Cycling On Perceived Stress, Arousal, And Attention, Alyssa G. Vigil, David J. Cleveland, Megan E. Ruhland, Ryan L. Olson

International Journal of Exercise Science: Conference Proceedings

Generally, acute bouts of aerobic exercise have been shown to enhance psychological measures of emotion, mood, and affect. Previous investigations suggest that perceived stress and arousal levels are especially influenced by exercise. Interestingly, very few studies have examined the influence of exercise on attention and whether changes in stress and arousal may augment adaptations in attentional orientation that are often required during exercise. Furthermore, very little is known about the timing of the effects of exercise on these psychological outcomes. PURPOSE: The primary purpose of this study was to examine the effects of low-intensity aerobic exercise on stress, arousal, and …

Recovery Of Hindlimb Bone Mass Following Prolonged Disuse, Nicholas A. Igbinigie, Corinne Metzger, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Bone is a dynamic tissue that responds to mechanical loads placed on it. For populations with extensive periods of disuse, like those in prolonged bed rest and astronauts during long-duration spaceflight, significant bone loss can occur. The purpose of this study was to determine the effects of prolonged disuse on weight-bearing bones and the length of time needed to recover disuse-induced bone loss utilizing the hindlimb unloading (HU) method in young rodents. We hypothesized that hindlimb bone mass would partially recover to age-matched control levels by 14 days of recovery following prolonged disuse and fully recover by 90 days of …
