The Pursuit Of Peak Athletic Performance, Trevor Short

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 4: Issue 1, Article 3, 2023. Achieving peak performance in sports is a multifactorial phenomenon that spans several scientific disciplines. The optimization of human performance requires a comprehensive and systematic assessment that identifies potential performance-inhibiting factors. The result of such analysis allows for more individualized and accurate evaluation, athlete monitoring, and training interventions. Thus, there is a need for a multidisciplinary model of peak performance to guide practitioners when conducting a comprehensive analysis. The purpose of this manuscript is to provide a brief but practical vade mecum for practitioners to consider in the …

Potentially Misleading Weight Loss Advertisements Targeting Men: Examining Influence Of Celebrity Athlete Endorsement On Ad Believability And Purchase Intentions, Andrew C. Pickett, Katie M. Brown, Zack J. Damon, Natasha T. Brison

Health Behavior Research

Given the prevalence of false or exaggerated claims in advertisements for weight loss products, as well as risks associated with use of unproven dietary supplements and exercise plans, they are subject to heightened scrutiny from regulators. However, celebrity athlete endorsers are increasingly featured in advertisements promoting weight loss products targeting men. This study employed a 2x2 (athlete endorser vs. non-celebrity; plausible vs. unrealistic advertising claim) experimental design, whereby participants (n= 292) were exposed to one of four ad conditions. Results suggest the athlete endorser was perceived as more credible than a non-celebrity, being rated as more expert. Significant …

Difference Of Elbow Extension Velocity During Flat And Mound Throwing, Omar Arizpe, Joshua Perez, Bryon C. Applequist

International Journal of Exercise Science: Conference Proceedings

In baseball, players encounter varying forms of throwing that is dependent upon position. Pitchers often throw on a mound, while position players are seen throwing from a flat ground. The throwing motion of a baseball consists of six phases: wind-up, stride, late cocking, acceleration, deceleration, and follow through. Each of these different phases consists of velocities being produced from the lower body through the elbow, which contributes to a potential cause of throwing arm injuries. Given the prominence of elbow injuries to pitchers, investigation into the solution to reducing arm injuries has continued to gain traction. PURPOSE: The purpose …

Pressurized Device For Mitigating Atrophy In Soleus During Long-Duration Spaceflight, Ramona Tovar Briones, Kimhab Sor, Breandrea Diaz, Dona Varghese, Benjamin Easter, Hunter Alvis, Brandon R. Rigby

International Journal of Exercise Science: Conference Proceedings

A major concern with long duration spaceflight, skeletal muscle atrophy is most detrimental in lower limb musculature, particularly in muscles critical for proper gait, such as the soleus. The decline of muscle activation and the suppression of sensory input from plantar sole mechanoreceptors can add to the attenuation of skeletal muscle health during spaceflight. More specifically, inhibition of sensory input from sole receptors, such as with gravitational unloading, decreases selective activation, thereby negatively affecting muscle tone and inevitably resulting in lower limb atrophy. PURPOSE: To design, fabricate, and test a specialized boot with an insole that applies oscillating pneumatic …

Food Sensitives In Athletes: Whey More Common Than You May Expect?, Eve M. Clarkson Miss, Brittanie L. Lockard, Ben Garza, Julianne Damico, Terah Ege

International Journal of Exercise Science: Conference Proceedings

Food sensitives, which differ from food allergies, are caused by digestive problems to foods that may lead to symptoms such as bloating, diarrhea, constipation, fatigue, headache, joint pain, and sleep disturbances, among other issues. It is estimated that food sensitivities affect 15-20% of the US population. These are IgG antibody-mediated responses that may develop from a variety of causes such as enzymatic defects in the digestive system. Research suggests that IgG-based tests produce clinically meaningful results that aid in the development of a targeted elimination diet. In a non-athletic sample with food sensitivities, our lab previously reported that 70% of …

Ectopic Bone In The Lungs And Spleen Of Male Fisher-344 Rats, Amanda Salas Sanchez, Teresa Le, Danyah Nashawi, Hannah Mitchell, Tara Dawn Kortlever, Rhonda Prisby

International Journal of Exercise Science: Conference Proceedings

Previous experimental data demonstrated ossified particles (OSP, i.e., bone-like particles) in the circulation of rodents as well as human subjects. Their ability to circulate could ultimately permit access to vital tissues, potentially leading to ectopic bone formation. Although the fate of OSP is yet unclear, their entry into soft tissues and organs may initiate pathological processes. PURPOSE: We sought to determine the presence of bone in the soft organs. METHODS: Young (6-mon; n=10) and old (24-mon; n=10) male Fisher-344 rats were anesthetized (3% isoflurane to oxygen balance) and euthanized by removal of the heart. Body mass (g) was …

Can We Calculate Mean Arterial Pressure In Humans?, Matthew M. Howrey, Tiffany L. Brazile, Bryce N. Balmain, Andrew R. Tomlinson, James P. Macnamara, Tony G. Babb, Benjamin D. Levine, Satyam Sarma, Christopher M. Hearon Jr, Denis J. Wakeham

International Journal of Exercise Science: Conference Proceedings

Mean arterial pressure (MAP) is either measured with an oscillometric cuff and then systolic (SBP) and diastolic (DBP) blood pressures are estimated from an unknown algorithm; or SBP and DBP are measured via auscultation and MAP calculated using measures of systolic pressure (SBP), diastolic pressure (DBP), and a form-factor (FF; equation: [(SBP-DBP)*FF]+DBP). The typical FF used is 0.33 though others (0.4) have been proposed. Recent work indicates that estimation of aortic MAP via a FF leads to inaccurate values and should therefore be interpreted with caution, whether this is the case for local MAP is unknown. While the implications for …

Meiyyappan, Ricardo Torres, Tomas Chapman-Lopez, Keri Collins, Bayley Humphrey, Andrew Gallucci, Brent Dragoo, Leslee Funderburk, Panagiotis Koutakis, Jeff S. Forsse

International Journal of Exercise Science: Conference Proceedings

The effect of vitamin D (VITD) on bone, muscle, and over health is well know in renal failure and chronic kidney disease (CKD). However, the influence of VITD on renal health and filtration (RHF) in healthy individuals is unclear. Currently, only serum creatinine concentration (sCr) methods are used to assess renal status in health individuals. However, newer biomarkers like serum Cystatin C (CyC) and urine epidermal growth factor (uEGF) show promise in evaluating baseline RHF. The impact of Vitamin D on filtration in healthy individuals of various ages is still unknown. PURPOSE: To determine the impact of VITD on RHF …

A Single 10-Minute Vape Exposure Alters Ventilation In Adult Rats, Mila Fisher, Jennifer A. Stokes

International Journal of Exercise Science: Conference Proceedings

E-cigarettes, also known as electronic nicotine delivery systems (ENDS), are an alternative to the traditional cigarette. ENDS function using a heating device (e.g. “vape pen”, such as JUUL) to heat liquids containing nicotine and other chemicals. Recent research in humans and animal models suggests that acute exposure (5 to 60 minutes) to e-cigarette vapor increases airway resistance and proinflammatory cytokine presence in lung tissue. These acute effects may lead to long term functional changes in the lung and tissue changes at the respiratory membrane. PURPOSE: The purpose of this study was to investigate the effects of an acute 10-minute …
