Effects Of A 28-Day Carbohydrate-Restricted Diet On Metabolic And Performance Markers In Professional Firefighters, Andrew E. Gonzalez, Hunter S. Waldman, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

PURPOSE:Firefighters (FF) experience acute physiological and psychological stressors such as disturbed sleep patterns, frequent snacking, smoke exposure, and intense physical exertion, likely contributing to a significant risk for cardiovascular disease (CVD) and sudden cardiac death. Additionally, FF have high obesity prevalence rates and low cardiovascular fitness levels. Proper dietary and exercise regime interventions may decrease CVD risk. Carbohydrate-restricted diets (CRD) may benefit FF health through increased metabolic flexibility, decreased fat mass, and improved body composition, without negatively affecting the strength and aerobic performance. METHODS:Twenty-one healthy, male professional FF recruited from local fire departments underwent 9 testing sessions: Trials …

Predicting Resting Metabolic Rate In Healthy Adults Using Body Composition And Circumference Measurements, Kristi L. Chase, Kyle T. Patek, John L. Walker, Joni A. Mettler Ph.D

International Journal of Exercise Science: Conference Proceedings

Measurement of resting metabolic rate (RMR) is an important factor for weight management. Previous research has reported several variables to estimate RMR such as body size, percent fat (%BF), age, and sex; however, little is known regarding the effect of circumference measures in estimating RMR. PURPOSE: The purpose of this study was to develop a model to estimate RMR using waist circumference (WC), an easily obtainable measure, and cross-validate it to previously published models. METHODS:Subjects were 140 adult men and women, ages 18-65 years. RMR was measured through indirect calorimetry, %BF was measured through air displacement plethysmography, and fat …


Impact Of Time Restricted Feeding On Markers Of Cardiometabolic Health, Liliana I. Renteria, Elias Villalobos, Hunter S. Waldman, Matthew J. Mcallister Feb 2019

Impact Of Time Restricted Feeding On Markers Of Cardiometabolic Health, Liliana I. Renteria, Elias Villalobos, Hunter S. Waldman, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

Time restricted feeding (TRF) is a form of intermittent fasting in which all calories are consumed within a certain amount of time (i.e. 6-8 hrs) only water is ingested for the remainder of the day. Previous research shows improvements in body composition and some markers of cardiometabolic health, but it is not clear if these results were due to the decreased eating window, or due to a decrease in caloric intake that typically occurs with fasting protocols. PURPOSE: to assess whether a caloric deficit is necessary to achieve improvements in cardiometabolic health as well as evaluate the impact TRF has …


The Effect Of Neuromuscular Electrical Stimulation On Metabolic Changes In A Sedentary Population: A Pilot Study, Michelle Galvan, Jasmin Jenkins, Sudip Bajpeyi Feb 2019

The Effect Of Neuromuscular Electrical Stimulation On Metabolic Changes In A Sedentary Population: A Pilot Study, Michelle Galvan, Jasmin Jenkins, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

The Centers for Disease Control and Prevention (2015) declared that 80% of U.S. adults do not meet exercise recommendations by ACSM. Skeletal muscle contraction has been shown to increase mitochondrial content (energy production) and glucose uptake (decreased insulin resistance). Neuromuscular Electrical Stimulation (NMES) utilizes electrical impulses to induce muscle contractions and can be used as an alternate strategy to induce muscle contraction in sedentary adults. However, it is not clear if NMES induced muscle contraction may improve insulin sensitivity and metabolic health. PURPOSE: The purpose of this study was to investigate the effects of two weeks of NMES on …


A Family History Of Type 2 Diabetes Does Not Impact Skeletal Muscle Lipid Content, Jasmin Jenkins, Sudip Bajpeyi Feb 2019

A Family History Of Type 2 Diabetes Does Not Impact Skeletal Muscle Lipid Content, Jasmin Jenkins, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

A high intramyocellular lipid (IMCL) has been associated not only with insulin resistance, obesity, and type 2 diabetes; but also in insulin sensitive endurance trained athletes – known as “athlete’s paradox”. A family history of type 2 diabetes (FH+) has been shown as a risk factor for the development of insulin resistance and type 2 diabetes (T2D). However, it is unclear whether a FH+ affects IMCL content and exercise induced changes in IMCL when compared to those without a family history of type 2 diabetes (FH-). PURPOSE: The purpose of this study were 1) to compare IMCL content between …


Exercise Leads To Increase In Smaller Lipid Droplet Morphology In Peripheral Region Of Muscle Fiber, Victoria Rosas Feb 2019

Exercise Leads To Increase In Smaller Lipid Droplet Morphology In Peripheral Region Of Muscle Fiber, Victoria Rosas

International Journal of Exercise Science: Conference Proceedings

In a previous study, we have shown that high fat overfeeding results in decreased smaller lipid droplet density in the peripheral region of skeletal muscle fiber. This decrease was associated with high fat overfeeding induced weight gain and insulin resistance. However, it is not clear whether an acute bout of exercise (elevated fat oxidation state) affects lipid droplet size. PURPOSE: To determine the effects of a single bout of endurance exercise on skeletal muscle lipid content and lipid droplet size. METHODS: Ten healthy male volunteers (Mean ± SEM; age: 23.11 ± 0.98; BMI: 23.27 ± 0.50 kg/m2) participated …


A Comparison Of High-Intensity Interval Exercise And Continuous Moderate-Intensity Exercise On Postprandial Metabolism: A Pilot Analysis., David J. Buckley, Broderick L. Dickerson, James R. Rowe Jr Feb 2019

A Comparison Of High-Intensity Interval Exercise And Continuous Moderate-Intensity Exercise On Postprandial Metabolism: A Pilot Analysis., David J. Buckley, Broderick L. Dickerson, James R. Rowe Jr

International Journal of Exercise Science: Conference Proceedings

Both moderate-intensity continuous exercise (MICE) (performed for ≥ 1 hour) and high-intensity interval exercise (HIIE) (performed for ≤ 30 minutes) has been reported to reduce the magnitude of postprandial lipemia and glycemia. It is unclear if low-volume MICE and HIIE performed for a similar duration and expending similar amounts of energy would have a comparable or different effect on postprandial lipemia or glycemia. PURPOSE: Examine the effects of low-volume MICE and HIIE on postprandial glucose, insulin, and triglyceride (TG) concentration following a mixed meal (MM) ingested at 0.5 hours and 15.5 hours post-exercise. METHODS: Recreationally active men (n = …

Curcumin And Boswellia Serrata Supplementation Result In Reduced Inflammation Following Eccentric Leg Press Exercise, Asheal A. Davis, Elizabeth A. Tanner, Melody A. Gary, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Repetitive exercise on consecutive days is a key component of many long-term training plans. This type of exercise results in muscle inflammation and soreness that limits the capacity to sustain exercise at a high effort. Several dietary polyphenols have the capacity to manage inflammation and thus supplementation may be an effective component of a long-term training plan. PURPOSE:The purpose of this study was to investigate the effect of combined oral supplementation with curcumin and boswellia serrata prior to and following three consecutive days of intense interval exercise. METHODS:All protocols were approved by the University IRB committee and participants …

Inflammation-Associated Rna Signaling Is Reduced Following A Half-Marathon Race When Supplemented With Curcumin And A Pomegranate Extract, Elizabeth A. Tanner, Melody A. Gary, Asheal A. Davis, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Prolonged endurance exercise performances provide a unique model for investigating the combined effects of oxidative stress and eccentric muscle contraction on differential gene expression with nutritional interventions known to blunt inflammation. Dietary polyphenols (i.e. curcumin, pomegranate, etc.) have been shown to reduce exercise-induced inflammation associated mRNA and protein expression with fewer side effects than NSAIDs. PURPOSE: To investigate the effect of combined curcumin (500-1000 mg/d; Longvida®) and pomegranate extract (500-1000 mg/d; Pomella®) supplement for 30-days on mRNA expression following a half marathon race. METHODS: All protocols were approved by the University IRB committee and participants gave written informed consent. Participants …

Effects Of Caffeine Dose Timing On The Time-Course Of Diuresis During Sodium-Aided Hyperhydration, Phillip D. Wickenheiser, Shelby Greene, Elizaveta Roslanova, Dave Morris Feb 2019

Effects Of Caffeine Dose Timing On The Time-Course Of Diuresis During Sodium-Aided Hyperhydration, Phillip D. Wickenheiser, Shelby Greene, Elizaveta Roslanova, Dave Morris

International Journal of Exercise Science: Conference Proceedings

When used alone, both caffeine and sodium-aided hyperhydration (SAH) can be ergogenic. Caffeine, when used with SAH, promotes diuresis, but hyperhydration can be achieved, albeit at lower levels than with SAH alone. In previous caffeine and SAH work, caffeine induced diuresis occurred only within 15 min of consumption of a bolus of caffeine, NaCl, and H2O. This suggests that caffeine-induced diuresis may occur for only 15 min after its consumption, and/or that the diuretic effect of caffeine is dependent on hydration levels. Caffeine has been shown to be ergogenic when taken as little as 5 min before exercise; …


Effects Of Caffeine Dose Timing On Total Urine Excretion During Sodium-Aided Hyperhydration Protocols, Shelby L. Greene, David M. Morris Feb 2019

Effects Of Caffeine Dose Timing On Total Urine Excretion During Sodium-Aided Hyperhydration Protocols, Shelby L. Greene, David M. Morris

International Journal of Exercise Science: Conference Proceedings

When used alone, both caffeine and sodium-aided hyperhydration (SAH) can be ergogenic. Although caffeine use in conjunction with SAH promotes diuresis, hyperhydration can be achieved, albeit at lower levels compared to SAH alone. Previous caffeine and SAH work has suggested most of the caffeine induced diuresis occurs within 15 min of consumption of a bolus of caffeine, sodium and water. This response suggests that caffeine-induces diuresis for only 15 min following its consumption, and/or that the diuretic effects of caffeine are dependent on hydration levels. PURPOSE: To determine the effects of caffeine, consumed at different time-points, on diuresis during SAH …
