Exercise has been shown to increase glucose uptake and GLUT-4 protein content in skeletal muscle following muscle contraction. PURPOSE: To determine the acute effects of a single bout of moderate intensity endurance exercise on skeletal muscle GLUT-4 content. METHODS: 10 healthy male volunteers (age: 24.4 ± 1.3 years; BMI 23.16 ± 0.60 kg/m²) participated in a single bout of endurance exercise on a cycle ergometer at 65% maximal aerobic capacity (VO_2max) for 1.5 – 2.0 hours (650kcal). Muscle biopsies were obtained from the vastus …

Exercise Leads To Increase In Smaller Lipid Droplet Morphology In Peripheral Region Of Muscle Fiber, Victoria Rosas

International Journal of Exercise Science: Conference Proceedings

In a previous study, we have shown that high fat overfeeding results in decreased smaller lipid droplet density in the peripheral region of skeletal muscle fiber. This decrease was associated with high fat overfeeding induced weight gain and insulin resistance. However, it is not clear whether an acute bout of exercise (elevated fat oxidation state) affects lipid droplet size. PURPOSE: To determine the effects of a single bout of endurance exercise on skeletal muscle lipid content and lipid droplet size. METHODS: Ten healthy male volunteers (Mean ± SEM; age: 23.11 ± 0.98; BMI: 23.27 ± 0.50 kg/m²) participated …

Skin Temperature And High Dew Point In Hot Environments Affects Self-Paced Exercise, Paolo Miguel Salvador, Julianna Kilpatrick, Kyleigh Allie, Eric Rivas

International Journal of Exercise Science: Conference Proceedings

Dew point (dp) is the absolute measure of water vapor and directly affects comfort whereas 5-10℃ feels dry; 10-15℃ feels comfortable and 20-24℃ feels uncomfortable.

Circulating Inflammatory And Oxidative Stress Responses To Steady-State Moderate-Intensity And High-Intensity Interval Exercise In Mid-Spectrum Chronic Kidney Disease, Matthew Peterson, Jeffrey S. Forsse, James K. Taylor, Zach Papadakis, Nick Schwedock, Burritt Hess, Jackson O. Griggs Md, Crawford Allison, Ron Wilson Md, Kathleen Adair, Mitch Cholewinski, Peter Grandjean

International Journal of Exercise Science: Conference Proceedings

Inflammation and oxidative stress can be potent modulators of vascular function. These factors may transiently respond to moderate-intensity steady state exercise (SSE) in a manner that improves post-exercise vascular function in healthy adults. Whether exercise imparts similar effects in adults with Stage 3 or 4 chronic kidney disease (CKD) remains understudied. Moreover, a comparison of SSE and high-intensity interval exercise (HIIE) may add to clinically-relevant findings for improving vascular function in mid-spectrum CKD. PURPOSE: To determine the influence of SSE and a comparable amount of HIIE on post-exercise inflammation and oxidative stress in patients diagnosed with secondary Stage 3 or …

PURPOSE: To determine the influence of SSE and a comparable amount of HIIE on indicators of post-exercise renal function in patients diagnosed with secondary Stage 3 or 4 CKD. METHODS: Twenty participants (n = 6 men; n = 14 women; age 62.0 + 9.9 yr; weight 80.9 + 16.2 kg; body fat 37.3 + 8.5% …

Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith

Faculty and Student Publications

© The Author(s) 2018. There is irrefutable evidence that regular participation in physical activity is favorably associated with numerous positive health outcomes, including cognitive function. Emerging work suggests that perceived physical activity, independent of actual physical activity behavior, is inversely associated with mortality risk. In this study, we evaluate whether perceived physical activity, independent of actual physical activity, is associated with cognitive function, a robust indicator of mortality risk. Data from the cross-sectional 1999–2002 National Health and Nutrition Examination Survey were employed (N = 2352; 60+ years of age). Actual physical activity was assessed via a validated survey. Perceived physical …

Exercise And Patient Populations: A Community-Based Exercise Intervention On Cancer And Type 2 Diabetes, Cynthia Villalobos

University of the Pacific Theses and Dissertations

Cancer and diabetes are the second and seventh leading causes of death in the United States, respectively (Kochanek et al., 2017). When including prediabetes and the entire cancer continuum, both diseases affect over 150 million individuals in the United States each year (Bullard et al., 2018; Siegel et al., 2019). Furthermore, there exists an alarming rise in patients presenting with both type 2 diabetes and obesity-related cancers concurrently, as both diseases share similar risk factors (Vigneri et al., 2009). An aging adult population, physical inactivity and unhealthy eating habits are continuing to rise, and the prevalence of individuals with obesity-related …

The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius

Research outputs 2014 to 2021

This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …

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. …

Interpreting Signal Amplitudes In Surface Electromyography Studies In Sport And Rehabilitation Sciences, Andrew D. Vigotsky, Israel Halperin, Gregory J. Lehman, Gabriel S. Trajano, Taian M. Vieira

Research outputs 2014 to 2021

Surface electromyography (sEMG) is a popular research tool in sport and rehabilitation sciences. Common study designs include the comparison of sEMG amplitudes collected from different muscles as participants perform various exercises and techniques under different loads. Based on such comparisons, researchers attempt to draw conclusions concerning the neuro- and electrophysiological underpinning of force production and hypothesize about possible longitudinal adaptations, such as strength and hypertrophy. However, such conclusions are frequently unsubstantiated and unwarranted. Hence, the goal of this review is to discuss what can and cannot be inferred from comparative research designs as it pertains to both the acute and …

Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …
