Persistent quadriceps dysfunction following anterior cruciate ligament reconstruction (ACLR) may lead to further pathological complication. Quadriceps weakness has been linked to corticospinal excitability. However, it remains unclear how this altered corticospinal excitability contributes to ACLR patients during knee strength tasks when compared to healthy controls. PURPOSE: The purpose of this study was to examine force reproduction strategies during isometric knee extension between ACLR patients and healthy controls. METHODS: Five ACLR (20.40±1.67yrs, 72.12±12.87kg, 171.07±7.40cm) participants and five matched healthy controls (21.00±1.73yrs, 65.77±13.61kg, 166.62±11.99cm) performed an isometric force reproduction task. They were instructed to maintain 10% of maximal voluntary isometric contraction (MVIC) …

Social Jetlag Inhibits Exercise-Induced Adaptations In The Heart And Alters Markers Of Mitochondrial Dynamics, Graham R. Mcginnis, Michael B. Dial, Elias M. Malek, Greco Neblina, Austin Cooper, Nikoleta Vasileva, Tanner Erwin
International Journal of Exercise Science: Conference Proceedings
Social jetlag (SJL), or the shifting of behavior and sleep times between weekdays and weekends, is a pervasive form of circadian rhythm disruption that affects nearly 70% of the population to some extent. The magnitude of SJL can be determined by the difference in the mid-sleep phase between weekends and weekdays. Higher levels of SJL have been associated with lower levels of cardiorespiratory fitness, and increased incidence of cardiometabolic disease, which may be due, in part, to mitochondrial dysfunction. However, no studies to date have evaluated the effects of long term SJL on cardiac mitochondrial dynamics. PURPOSE: To determine …
Effects Of Partial Hot Water Immersion On Postprandial Blood Glucose And Heart Rate Variability, Jeff Moore, Michael Buono
Effects Of Partial Hot Water Immersion On Postprandial Blood Glucose And Heart Rate Variability, Jeff Moore, Michael Buono
International Journal of Exercise Science: Conference Proceedings
The acute effects of heat therapy on glycemic markers oppose those of the chronic effects. While the postprandial glucose response is exaggerated during whole body heat exposure, chronic heat exposure lowers HbA1c. Additionally, the acute effects of heat therapy differ depending on the amount of body exposed to heat. Heating a single hand does not increase fasting glucose and lowers postprandial glucose. The opposing effects of partial and whole body heat exposure could be mediated in part from increased sympathetic nervous system (SNS) activity following heat stress. While heating the body increases muscular blood flow and glucose uptake, SNS activation …

Validation Of Vertical Force Measures During Hop Tasks Using Pressure Insoles, Andrew Cho, Erin Cagle, Sylwia Lipior, Susan Sigward
Validation Of Vertical Force Measures During Hop Tasks Using Pressure Insoles, Andrew Cho, Erin Cagle, Sylwia Lipior, Susan Sigward
International Journal of Exercise Science: Conference Proceedings
Assessment of vertical ground reaction forces (vGRF) during jumping and landing tasks is commonly used as a tool to quantify limb loading following injury. While embedded force plates are the current gold standard, cost and poor ecological validity limit their feasibility for assessment of loading during sport agility tasks. Wearable pressure insoles can measure plantar pressure wirelessly and may provide an alternative for on-field assessments. Previous studies have assessed the validity of insoles with varying results. Few studies have considered tasks that require both vertical and horizontal forces similar to those required for agility tasks. This may have important implications …
Differential Contribution Of Cardiac And Peripheral Blood Flow To Metaboreceptor-Mediated Pressor Responses In Autism Spectrum Disorder, Matthew Pizano Gomez, Gabriel B. Carlota, Stephanie S. Wang, Areum K. Jensen
Differential Contribution Of Cardiac And Peripheral Blood Flow To Metaboreceptor-Mediated Pressor Responses In Autism Spectrum Disorder, Matthew Pizano Gomez, Gabriel B. Carlota, Stephanie S. Wang, Areum K. Jensen
International Journal of Exercise Science: Conference Proceedings
Young adults with Autism Spectrum Disorder (ASD) experience a higher prevalence of hypertension than the general population. Abnormal blood pressure (BP) response to acute exercise is seen in hypertension. BP response evoked during exercise is the outcome of a central interaction between neural inputs such as the exercise pressor reflex. However, it is unclear if this neurocardiovascular interaction is altered differently to regulate BP during exercise in ASD. PURPOSE: To determine whether contributions of cardiac and peripheral blood flow to metaboreceptor-mediated pressor responses are different during exercise in ASD. METHODS: 21 young adults with and without ASD completed the study. …

A Novel Waveform To Extract Exercise Gas Exchange Response Dynamics: The Chirp Waveform, Michele Girardi, Michael A. Roman, Janos Porszasz, William W. Stringer, Carrie Ferguson, Harry B. Rossiter, Richard Casaburi
International Journal of Exercise Science: Conference Proceedings
Characterizing exercise gas exchange response dynamics reveals important information about physiological control processes and cardiopulmonary dysfunction. However, current methods for extracting exercise response dynamics typically use multiple step-wise transitions, limiting applicability of this technique. PURPOSE: We designed a new protocol (chirp waveform) to extract exercise gas exchange response dynamics in a single visit. We tested the hypothesis that gas exchange response dynamics extracted from chirp forcing would be similar to those extracted from step-wise transitions. METHODS: Thirty-one participants (14 young healthy, 7 older healthy, and 10 patients with chronic obstructive pulmonary disease) visited the laboratory on three occasions. …

Examining Stroke Volume Changes During Exercise In Healthy Young Adults, Thomas Clark, Anthony Ciccone, Zane Evans, Keslee Stephenson, Chandler Rose, Carlos Goff, Shane Draper, Nicolas Clark
International Journal of Exercise Science: Conference Proceedings
Cardiac output is determined by the combination of heart rate and stroke volume. While heart rate is primarily influenced by cardiac autonomic input, stroke volume's behavior is more intricate due to the interplay between myocardial response to stretch (Frank-Starling law) and adrenergic changes in contractility. No consensus exist on its behavior during exercise despite extensive data. PURPOSE: The aim of this study was to assess how normalized stroke volume scores (SV) change in young, healthy adult males during a graded exercise test to exhaustion (GXT). METHODS: Participants (n=20; age=22.9±2.4; BMI=23.7±2.4) were instructed to abstain from engaging in vigorous …

Validation Of The Work Capacity Test For Wildland Firefighters, Cassandra Mcfarland, Zachary Hofheins, Janna Thompson, Lexi Sorensen, Andrew Creer, Shane Draper
International Journal of Exercise Science: Conference Proceedings
Much of the reported Wildland Firefighter (WLFF) data use prediction equations which tend to underestimate oxygen consumption (VO2) during load carriage. As a result, the reported metabolic and oxygen consumption data values may actually be higher creating a larger gap between the US Forest Service arduous pack test (APT) and true occupational demand. The reported data regarding the energy cost upon which the APT has been based (22.5 mL/kg/min of oxygen) has overwhelmingly been tested in current WLFF with few participants. However, no studies have recently examined the current energy expenditure of men and women who want to qualify to …
