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 …

Diaphragm Force And Mitochondrial Function Ex Vivo Following Gsnor Inhibition In Vivo Preceding Mechanical Ventilation, Simon P. Pierce, Daniel T. Cannon, Leonardo Nogueira
International Journal of Exercise Science: Conference Proceedings
During mechanical ventilation (MV), force developed by the diaphragm is decreased over time much faster than locomotor muscles. This is known as ventilator-induced diaphragm dysfunction (VIDD), and VIDD may be accelerated by intramyofiber oxidative stress. An important free radical used for the treatment of acute respiratory distress syndrome (ARDS) is nitric oxide (NO) which can diffuse to diaphragm myofibers during treatment. However, little is known whether NO or NO by-products such as S-nitrosothiols (RSNO), can accelerate or prevent VIDD. PURPOSE: To investigate whether inhibiting S-nitrosoglutathione reductase (GSNORi) during MV could affect ex vivo diaphragm force and mitochondrial respiration. METHODS …

Intra And Inter-Rater Reliability Of The Exercise Thresholds App In Identifying Ventilatory Thresholds Using Undergraduate Raters, Anna Grexton, Dante Argento, Holland Gaston, Cory Greever
International Journal of Exercise Science: Conference Proceedings
Identifying the gas exchange threshold (GET) and the respiratory compensation point (RCP) are the least invasive methods for determining aerobic training zones from maximal graded exercise tests. This process requires a thorough examination of several respiratory gas exchange parameters from breath-by-breath or time binned averages. Given the nature of processing data in this fashion, standardized tools could be useful in improving exercise physiology student’s accuracy in identifying these thresholds. The Exercise Thresholds App is a computer application developed to simultaneously visualize eight different respiratory gas exchange parameters (VE, VO2, VCO2, VE/VCO2, VE/VO2, PETO2, PETCO2, RER) from maximal exercise tests …
Rare Case Of Traction Sural Neuropathy Due To Acute Achilles Tendon Rupture, Heather Lystad, Kenneth Vitale
Rare Case Of Traction Sural Neuropathy Due To Acute Achilles Tendon Rupture, Heather Lystad, Kenneth Vitale
International Journal of Exercise Science: Conference Proceedings
Sural nerve injury (SNI) is a reported complication of acute Achilles tendon rupture (ATR), primarily iatrogenic in operatively managed cases. The sural nerve typically runs along the lateral border of the Achilles tendon. Its branches provide sensory information from the lateral foot and ankle. Given its proximity to the Achilles tendon, sural nerve-related complications in operatively managed cases are a known adverse outcome. However, the incidence of SNI in conservatively managed cases is thought to be much less common. Most patients recover to normal sensation by one year of injury to the sural nerve. CASE DESCRIPTION: A previously healthy 30 …

Abdominal Adiposity Indexed By The Sagittal Abdominal Diameter And Risk Of Mortality In 14,119 U.S. Adults, Joshua A. Brockbank, Larry A. Tucker
International Journal of Exercise Science: Conference Proceedings
The body mass index (BMI) is frequently used as a general measure of overweight and obesity. It is a good predictor of disease and premature death. However, research shows that indices of abdominal adiposity tend to be better predictors of disease risk and mortality than BMI. To date, the sagittal abdominal diameter (SAD), an index of abdominal adiposity, has never been evaluated as a predictor of mortality. PURPOSE: The present study was conducted to determine the extent that adults with different levels of SAD vary in their risk of all-cause mortality over an average follow-up of 6 years. METHODS: A …

International Journal of Exercise Science: Conference Proceedings
Resistance exercise is known to produce muscle hypertrophy. However, little is known about the role of muscle satellite cells in generating new myofibers or in incorporating satellite cells to live myofibers during exercise training. PURPOSE: To investigate whether single-leg resistance exercise training can activate the incorporation of muscle satellite cells in mice. METHODS: Transgenic male mice (12 weeks old) that express Td-Tomato fluorescent protein in Pax7+ (i.e., satellite cells) cells (Pax7CreER-Ai9) were treated with tamoxifen (2 mg in corn oil, i.p.) once a day for 5 days. Three days later, mice were single-leg exercise trained (i.e stimulation of …
