Developing A Predictive Model For Vo2max In Middle-Distance Track And Field Athletes, Nicole Vargas, Patricia Vanoosbree, Kristyne Wiegand

International Journal of Exercise Science: Conference Proceedings

Purpose: Aerobic capacity is an indicator of an athlete’s endurance and a key predictor of performance. The greater the aerobic capacity, the more oxygen available for working muscles, leading to delays in lactate buildup, thus increasing the potential for successful performance. Studies have investigated non-exercise and/or submaximal exercise measures to predict aerobic capacity, but few have analyzed the combination of maximal exercise and non-exercise measures in Division-3 runners. Therefore, the purpose of this pilot study is to determine the predictive ability of heart rate (HR_max), ventilation (VE), respiratory quotient (RQ), and rate of perceived exertion (RPE) on VO …

Understanding And Communicating Physical Activity Guidelines: Creating A Training Video For Health Care Providers, Jafrā D. Thomas, Bethany C. Love, Caroline N. Smith

International Journal of Exercise Science: Conference Proceedings

Participants completed assessments for muscular strength (predicted 1-repetition maximum of incline bench press, seated cable row, latissimus …

Reverting To A Healthier Diet Or Employing An Aerobic Exercise Regime Independently Restore Muscle Fiber Phenotype Disturbed By High-Fat Diet In Muscle Of Mice, Nathan Serrano, Harkaran S. Sodhi, Kailin Johnsson, Laurel B. Winslow, Layla Al-Nakkash, Christos S. Katsanos

International Journal of Exercise Science: Conference Proceedings

Obesity affects roughly 42% of the US population. High fat/high sugar diets (HFHS) often referred to as “western diet” contributes to this prevalence. Diet-induced obesity results in impaired metabolic responses and associated disease states (i.e., Type 2 Diabetes). Metabolic impairments in diet-induced obesity are a result of changes in muscle metabolism, and changes in muscle fiber phenotype, which is determined by the isoform-content of the protein myosin heavy chain (MHC). Fast muscle fiber phenotype (i.e. type IIb in mice) is characterized by lower capacity for utilization of lipids, implicated in the pathogenesis of Type 2 Diabetes. Regular exercise shifts MHC …

Obstacle Negotiation Gaze Strategies Of The Physically Fatigued, Belle P. Ponce De Leon, Makena Savola, Sedona Boren, Andrew Fishman, Sarika Varma, Jacob W. Hinkel-Lipsker

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Proper obstacle negotiation while in a fatigued state is a safety concern for first responders, firefighters and other primary relief personnel in their high-risk line of work. During locomotion the central gaze is focused beyond the obstacle to plan future steps while the peripheral vision spatially tracks the obstacle. Previous work indicates that following intense exercise people experience a narrowed peripheral visual field, making them more reliant on central gaze. Thus, it is possible that when physically-fatigued people become more reliant on central gaze to perceive obstacles, leaving them unable to plan future steps as effectively.

PURPOSE: This study …

Anthropometric Predictors Of Arterial Stiffness When Adjusting For Fitness In College-Aged Adults, Riley Morton, Kyli Alvarez, Estephania Campa, Malia Nowlen, Zachary Zeigler

International Journal of Exercise Science: Conference Proceedings

PURPOSE: Cardiovascular Disease (CVD) is the largest cause of non-communicable disease death worldwide. Arterial stiffness is an independent predictor of CVD. Body mass index (BMI), waist circumference (WC), and waist-to-hip ratio predict arterial stiffness. However, there is inconstancy in the literature as to which is the best predictor of arterial stiffness. Measured cardiovascular fitness is also an independent predictor of arterial stiffness and is rarely controlled for in epidemiological studies. The purpose of this study was to identify the superior anthropometric predictor of arterial stiffness after controlling for measured fitness.

METHODS: Healthy young adults were recruited from Grand …

Effects Of Short Foot Exercise On Ankle Eversion Velocity, Daniel Metri, Jacob Mayoral, Connor Owen, Andy Arant, Dane Johnson, Robert Dudley, Andrea Du Bois

International Journal of Exercise Science: Conference Proceedings

The biomechanical position of the foot while landing plays a major role in performance and injury. A common issue of landing is excessive foot pronation and subsequently ankle eversion. This biomechanical position can result in knee abduction, increasing the chance of knee injury. The velocity at which the ankle everts may also be a component of injury as long distance runners that became injured had higher ankle eversion velocity in their landing strides while running. Short foot exercise (SFE) strengthens the intrinsic muscles of the foot and help stabilize the arch which assists in eccentrically controlling pronation. However, acute effects …

Macrophage Response To Damage In Old And Young Skeletal Muscle, Jack Mehling, Robert D. Hyldahl, Mohadeseh Ahmadi

International Journal of Exercise Science: Conference Proceedings

PURPOSE: In skeletal muscle, macrophages migrate to damaged fibers, influencing the inflammatory response during muscle regeneration. Macrophages experience polarization, exhibiting different phenotypes described as M1 (pro-inflammatory) and M2 (anti-inflammatory.) Failure to properly transition between phenotypes inhibits fiber regeneration. Previous animal literature suggests that dysregulated macrophage polarization may contribute to the decreased regenerative capacity of aging muscle. The purpose of this study is to quantify macrophage response and polarization in a model of muscle damage and regeneration in older humans. We hypothesized that older people would have a higher percentage of M2 macrophages relative to the young. METHODS: Seven …

Uphill, Level, And Downhill Running In A New Style Of Road-Racing Shoe, Hunter Mcwilliams, Iain Hunter, Jared Ward, Cal Bradshaw, Tyler Standifird

International Journal of Exercise Science: Conference Proceedings

Recent changes in road-racing shoe construction has prompted research comparing the metabolic benefit of new shoe constructions compared to older styles. Kinematic and kinetic changes with uphill and downhill running may affect the magnitude of benefit for this new style of racing shoe. PURPOSE: Due to the changes associated with downhill running, we hypothesize that new performance racing shoes will have a greater metabolic benefit when running downhill, than with level or uphill running. METHODS: Eighteen subjects (10 men and 8 women) ran on two separate days with shoe order reversed. They wore either the Saucony Type A …
