The Effects Of Hiit Versus Mict And Sedentary Controls On Blood Lipid Concentrations In Nondiabetic Overweight And Obese Young Adults: A Meta-Analysis., Christian P. Mccormick, Garrett Mamikunian, David B. Thorp
International Journal of Exercise Science
International Journal of Exercise Science 16(3): 791-813, 2023. With rates of obesity and dyslipidemia rising among young adults, this meta-analysis aimed to compare the effects of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) and sedentary controls (CON) on low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG), and total cholesterol (TC) in nondiabetic overweight and obese young adults to determine if HIIT or MICT is more efficacious in improving dyslipidemia. Studies included in the analysis had to be randomized controlled trials or quasi-experimental studies, comparing the effects of HIIT versus MICT or CON on at least three variables of …

The Metabolic And Physiological Demands Of A Simulated Fire Ground Test Versus A Live-Fire Training Evolution In Professional Firefighters, Drew Edward Gonzalez, Hunter Waldman, Matthew J. Mcallister
International Journal of Exercise Science
International Journal of Exercise Science 16(7): 230-241, 2023. Objective: This study examined the similarities in metabolic and physiological demands of a fire ground test (FGT) and a live fire training evolution. Methods: Twenty-seven firefighters completed either a FGT (n = 13) or a live fire training evolution (n = 14). Salivary samples were collected pre, immediately post, and 30-minutes post FGT and live fire training evolution, and analyzed for cortisol, uric acid, and interleukin-1β (IL-1β). Heart rate (HR) was measured pre- and post-task. Results: Both tasks resulted in significant elevations in cortisol, IL-1β, and HR. Conclusions: Both the …

Heart Rate Responses During Simulated Fire Ground Scenarios Among Full-Time Firefighters, Quincy R. Johnson, Jonathan Goatcher, Cody L. Diehl, Robert G. Lockie, Robin Marc Orr, Brent Alvar, Doug Smith, J. Jay Dawes
International Journal of Exercise Science
International Journal of Exercise Science 13(2): 374-382, 2020. Simulated fire ground scenarios (SFGS) provide firefighters with an opportunity to maintain skills, receive feedback, and optimize performance. Although there is extensive research on heart rate (HR) changes in the firefighter population, few examine the differences between positions. Firefighters are primarily responsible for fire suppression and control (23), officers for emergency operations and organizational management, paramedics for providing on-scene emergency medical care, and drivers are responsible for driving the fire apparatus. Utilizing HR analysis to quantify the physical demands of SFGS among firefighting crews by position. Sixty-seven male (age: 38.97 ± 9.17; …
Effects Of Home-Based Exercise Training Systems, Combined With Diet, On Cardiometabolic Health, Christian K. Roberts, David E. Segovia, Eli Lankford
Effects Of Home-Based Exercise Training Systems, Combined With Diet, On Cardiometabolic Health, Christian K. Roberts, David E. Segovia, Eli Lankford
International Journal of Exercise Science
International Journal of Exercise Science 12(2): 871-885, 2019. The efficacy of exercise training systems designed to be used in the home on cardiometabolic outcomes remains largely unknown. This investigation included two studies. Study 1 tested the effects a multi-exercise pulley system(NordicTrack Fusion CST with video trainer) and Study 2 an incline trainer (NordicTrack X22i with video trainer), both combined with daily food provision, for 12-weeks on indices of cardiometabolic health. Study 1 enrolled 27 adults (11 men, 16 women, 33.8±4.4 years of age) and Study 2 enrolled 29 adults (11 men, 18 women, 40.8±12.5 years of age). Pre- and post-intervention …
A Comparison Of Blood Viscosity And Hematocrit Levels Between Yoga Practitioners And Sedentary Adults, James Shadiow, Takashi Tarumi, Mandeep Dhindsa, Stacy D. Hunter
A Comparison Of Blood Viscosity And Hematocrit Levels Between Yoga Practitioners And Sedentary Adults, James Shadiow, Takashi Tarumi, Mandeep Dhindsa, Stacy D. Hunter
International Journal of Exercise Science
International Journal of Exercise Science 12(2): 425-432, 2019. Elevations in whole blood viscosity (WBV) and hematocrit (Hct), have been linked with increased risk of cardiovascular disease (CVD). Endurance training has been demonstrated to lower WBV and Hct; however, evidence supporting the efficacy of yoga on these measures is sparse. A cross-sectional study was conducted examining WBV and Hct levels between yoga practitioners with a minimum of 3 years of consistent practice and sedentary, healthy adults. Blood samples were collected from a total of 42 participants: 23 sedentary adults and 19 regular yoga practitioners. Brachial arterial blood pressure (BP) was measured …

International Journal of Exercise Science: Conference Proceedings
Low- to moderate-intensity exercise has been widely recommended for people at any age to improve cardiovascular health due to its positive effects on blood lipids and lipoproteins. Recently, many people have been participating in not only low- to moderate-intensity, but high-intensity exercise as well in order to improve their cardiovascular health. However, it is unclear whether high-intensity exercise, particularly resistance exercise, can positively influence blood lipids and lipoproteins. Purpose: The current study examined the effects of low- and high-intensity of resistance exercise on changes in blood lipids and lipoproteins. Methods: In a randomized, cross-over design, 10 healthy recreationally resistance-trained (at …

Effects Of Acute Cold Exposure On Plasma Biomarkers Associated With Cardiovascular Disease Risk, Michael A. Levi, Jeremy Garcia, Steven Stelly, Donovan Fogt
International Journal of Exercise Science: Conference Proceedings
Background and Aims: The underlying cause of the majority of the cases of CVD is atherosclerosis, which is a condition initiated and progressed by chronic inflammation and hyperlipidemia. We are interested in evaluating the efficacy of cold-exposure to increase shivering- and non-shivering thermogenesis energy expenditure (RMR) as a non-pharmaceutical weight loss tool analogous to low intensity exercise. Naturally, we are concurrently evaluating the possible effects of cold exposure on risk factors associated with CVD risk. Inflammatory cytokines and lipid mediators are used as biomarkers for CVD risk. This proposed study aims to measure cardiovascular inflammatory and lipid biomarkers to expand …
