Spinal And Supraspinal Motor Control Predictors Of Rate Of Torque Development, S. T. Johnson, Kristof Kipp, M. F. Norcross, M. A. Hoffman

Exercise Science Faculty Research and Publications

During explosive movements and potentially injurious situations, the ability to rapidly generate torque is critical. Previous research has suggested that different phases of rate of torque development (RTD) are differentiately controlled. However, the extent to which supraspinal and spinal mechanisms predict RTD at different time intervals is unknown. RTD of the plantarflexors across various phases of contraction (i.e., 0–25, 0–50, 0–100, 0–150, 0–200, and 0–250 ms) was measured in 37 participants. The following predictor variables were also measured: (a) gain of the resting soleus H-reflex recruitment curve; (b) gain of the resting homonymous post-activation depression recruitment curve; (c) gain of …

Effects Of The Jaqbloq Forearm And Straight Arm Plank On Core Muscle Activation, Jacquelyn R. Clark

Human Movement Studies & Special Education Theses & Dissertations

Performing a plank has various benefits for all fitness levels. There are several different types of planks that can be performed, with or without equipment: straight arm, forearm and side plank. When one has a shoulder or arm injury, he or she will not be able to safely perform a plank. A piece of fitness equipment was recently designed to aid people with injuries so they can still perform a plank; the JAQBLOQ. It is a 12x13x14" high density EVA foam block used to assist one during a plank where the participant rests his or her chest on it.

Involvement Of The Right Hemisphere In Reading Comprehension: A Dti Study, Tzipi Horowitz-Kraus, Yingying Wang, Elena Plante, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty Publications

The Simple View of reading emphasizes the critical role of two factors in normal reading skills: word recognition and reading comprehension. The current study aims to identify the anatomical support for aspects of reading performance that fall within these two components. Fractional anisotropy (FA) values were obtained from Diffusion Tensor images in twenty-one typical adolescents and young adults using the Tract Based Spatial Statistics (TBSS) method. We focused on the Arcuate Fasciculus (AF) and Inferior Longitudinal Fasciculus (ILF) as fiber tracts that connect regions already implicated in the distributed cortical network for reading. Our results demonstrate dissociation between word-level and …

All Faculty Scholarship for the College of the Sciences

Background and Aims: Past research has examined eating disorder risk among college students majoring in Nutrition and has suggested an increased risk, while other studies contradict these results. Exercise Science majors, however, have yet to be fully examined regarding their risk for eating disorders and exercise dependence. Based on pressures to fit the image associated with careers related to these two disciplines, research is warranted to examine the potential risk for both eating disorder and exercise dependence. The purpose of this study is to compare eating disorder risk, exercise dependence, and body weight dissatisfaction (BWD) between Nutrition and Exercise Science …

Changes In The Number Of Circulating Cd34+ Cells After Eccentric Exercise Of The Elbow Flexors In Relation To Muscle Damage, Ho Seong Lee, Makii Muthalib, Takayuki Akimoto, Kazunori Nosaka

Research outputs 2014 to 2021

Background: It has been reported that strenuous exercise increases the number of bone marrow-derived progenitor cells such as CD34⁺ cells in the blood, but no previous studies have investigated the changes in circulating CD34⁺ cells following resistance exercise. This study tested the hypothesis that the number of CD34⁺ cells in the blood would increase after eccentric exercise of the elbow flexors, but decrease in recovery, and the magnitude of the changes would be dependent on the magnitude of muscle damage.

Methods: Nine men (28.0 ± 6.6 years) performed exercises consisting of 10 sets of six maximal voluntary …

Upper Body Posture And Pain In Division I Female Volleyball And Softball Athletes, Brittany M. Plunkett Castilla

Dissertations and Theses

Participation in athletics is a popular pastime and form of entertainment. Children often begin to specialize in one sport at a young age in an effort to excel, which increases physical stress and the potential for injuries. Athletes participating in overhead sports are at increased risk of upper body chronic injuries, in part because the shoulder is an unstable hypermobile joint. Posture may also be affected in these athletes because of the demands placed on the upper body. The purpose of this study was to measure the upper body posture in a sample of Division I collegiate volleyball and softball …

Non-Steroidal Anti-Inflammatory Drug Use In Collegiate Athletes, Brian Robert Davis

Dissertations and Theses

Non-steroidal anti-inflammatory drugs (NSAID) are a class of medications used in the treatment of pain, inflammation, and illness. These medications are common, affordable, and easy to access. For these reasons, NSAIDs are commonly used by athletes of all backgrounds for treating injuries and as ergogenic aids. However, despite these behaviors, NSAIDs have well-documented side effects and the efficacious nature of these medications has been brought into question. Despite this, many athletes continue to use these medications frequently and indiscriminately. It is not known why athletes use these medications in light of their questionable effectiveness and cited adverse effects. Therefore, this …

Differences In Muscle Activation While Gripping A Sandbag Versus An Olympic Weightlifting Bar 2015, Todd Luther

Master's Theses

The purpose of this study was to compare the myoelectric activity of the extensor carpi ulnaris, flexor carpi ulnaris, flexor carpi radialis, and opponens pollicis muscles while gripping a 50 lb Olympic weightlifting bar to the myoelectric activity of the same muscles while gripping a sandbag of the same weight. Myoelectric activity was measured as the average root mean square (RMS) of the surface electromyography (sEMG) values. The hypothesis was that gripping a sandbag would result in greater muscle activation of the extensor carpi ulnaris, flexor carpi ulnaris, flexor carpi radialis, and opponens pollicis muscles than gripping an Olympic weightlifting …
