Exercise-Induced Th17 Lymphocyte Response And Their Relationship To Cardiovascular Disease Risk Factors In Obese, Post-Menopausal Women, Maria A. Cardenas, Michael M. Levitt, Bryan Richie, Shaohan Lu, Elise Erickson, Carmen Cook, Jay Haynes, Andreas Kreutzer, Joel B. Mitchell, Melody D. Phillips

International Journal of Exercise Science: Conference Proceedings

Obesity-induced inflammation promotes type 2 diabetes and cardiovascular disease (CVD). A causative link between adaptive immunity and pathogenesis of obesity-associated diseases has been established. PURPOSE: To examine the effects of exercise on circulating T-helper (Th) 17 lymphocytes in overweight/obese post-menopausal women. METHODS: Twenty-seven overweight/obese women (BMI 32.7 ± 5.1 kg×m-2, 55-75 yr) were randomly assigned to the exercise (EX, n=14) or education (ED, n=13) groups. EX performed a 25-min walk (75-80% HRR) and 2 sets of 8 resistance exercises (70-80% 1RM) with blood samples obtained at: pre-exercise, post-exercise, one-hour and two-hour post-exercise. Blood samples were obtained …

Accelerometer-Determined Physical Activity And Sedentary Behavior Among Majority-Minority Sample Of Adults: The Houston Train Study, Ashleigh Johnson, Kelley Pettee Gabriel, Deborah Salvo, Erin Dooley, Casey Philip Durand, Gregory Knell, Samantha Kreis, Harold W. Kohl Iii

International Journal of Exercise Science: Conference Proceedings

Based on self-reported data, minority populations are often found to be less active compared to whites, which may contribute to overall health disparities. The Houston Travel Related Activity in Neighborhoods (TRAIN) Study provides an opportunity to examine differences in accelerometer-determined physical activity levels among a majority-minority sample of adults. PURPOSE: To describe and examine differences in accelerometer-determined physical activity and sedentary behavior among TRAIN participants at baseline, by race/ethnic groups and sex. METHODS: Study participants were part of an ongoing natural experiment of transportation-related physical activity. At baseline, a group of participants self-selected to wear an ActiGraph wGT3X-BT …

Accuracy Of Fitbit Charge 2 At Estimating Vo2max, Calories, And Steps On A Treadmill, Naomi D. Lucio, Elvia V. Salazar, Ivan A. Figueroa, Jose L. Gamez, Ryan D. Russell, Merrill D. Funk Feb 2018

Accuracy Of Fitbit Charge 2 At Estimating Vo2max, Calories, And Steps On A Treadmill, Naomi D. Lucio, Elvia V. Salazar, Ivan A. Figueroa, Jose L. Gamez, Ryan D. Russell, Merrill D. Funk

International Journal of Exercise Science: Conference Proceedings

Current fitness activity trackers can account for steps, calories burned, heart rate, and distance traveled. A new feature has recently been introduced on the Fitbit Charge 2, “Cardio Fitness Level,” which is comparable to a VO2max score in that it allows consumers to be aware of their aerobic fitness level. PURPOSE: To assess the accuracy of the Fitbit Charge 2 at estimating VO2 score (“Cardio Fitness Level”), calories, and steps when compared to indirect calorimetry and video analyzed steps, respectively. METHODS: Twenty-two healthy adults (Mean±SD; 24.1±4.2yrs; 16.9±9.0%fat; 15 male) completed two separate visits. On the first visit, anthropometric measurements were …

Diet And Sex Differences Induce Unique Alterations Of Markers For Blood Brain Barrier Integrity In Age-Accelerated Mice, Dakota R. Kamm, Kenneth A. Witt, Karin E. Sandoval, Megan L. Schaller, Matthew P. Harris, Joshua S. Wooten Feb 2018

Diet And Sex Differences Induce Unique Alterations Of Markers For Blood Brain Barrier Integrity In Age-Accelerated Mice, Dakota R. Kamm, Kenneth A. Witt, Karin E. Sandoval, Megan L. Schaller, Matthew P. Harris, Joshua S. Wooten

International Journal of Exercise Science: Conference Proceedings

The role of diet on brain health has received significant attention, with the Western diet (WD) contributing to cerebrovascular alterations and neurodegenerative disease. The blood-brain barrier (BBB) may play a particularly important role as it forms the interface between the peripheral circulation and the central nervous system. The WD has been shown to negatively impact the BBB. Whether there are sex specific differences with diet on BBB integrity remains unclear. PURPOSE: To determine the effect of diet and sex on the mRNA expression of markers of BBB integrity in an age-accelerated mouse model. METHODS: Male and female Senescence …

What Determines The Metabolic Cost Of Human Running Across A Wide Range Of Velocities?, Shalaya Kipp, Alena Marie Grabowski, Rodger Kram Feb 2018

What Determines The Metabolic Cost Of Human Running Across A Wide Range Of Velocities?, Shalaya Kipp, Alena Marie Grabowski, Rodger Kram

International Journal of Exercise Science: Conference Proceedings

The cost of generating force hypothesis proposes that the metabolic rate during running is determined by the rate of muscle force development (1/tc, tc=contact time) and volume of active leg muscle. A previous study assumed a constant recruited muscle volume and reported that the rate of force development alone explains ~70% of the increase in metabolic rate for human runners across a moderate velocity range (2-4 m s-1). PURPOSE: We performed a more systematic analysis of the effective mechanical advantage (EMA) of the lower leg over a wide velocity range to determine if …

Validity Of Cardiorespiratory Fitness Assessment In Adolescents Using The Non-Exercise Test, Pacer, And The K4b2 Portable Metabolic System, Pedro Migliano, Megan James, Allison Hall, Amy Fruge, Anna Flipse Feb 2018

Validity Of Cardiorespiratory Fitness Assessment In Adolescents Using The Non-Exercise Test, Pacer, And The K4b2 Portable Metabolic System, Pedro Migliano, Megan James, Allison Hall, Amy Fruge, Anna Flipse

International Journal of Exercise Science: Conference Proceedings

Cardiorespiratory fitness (CRF) is an important indicator of adolescent cardiovascular and future cardiometabolic health. The PACER test is often used to measure CRF in adolescents but is not feasible with pediatric populations unable to perform physical testing secondary to physical impairments. The non-exercise test (NET) has been recommended as a proxy for estimating VO2 in individuals not able to perform physical tests by using variables such as gender, age, body mass index, resting HR, and self-reported habitual physical activity levels. PURPOSE: The purpose of this study was estimate the concurrent validity of the NET for adolescents against the PACER …

Metabolic Responses To A Battling Rope Protocol Performed In The Seated Or Stance Positions, Dominisha Felder, Kasey Hogan, Reka Kovacs, Hannah Mitchell, Wayne Brewer Feb 2018

Metabolic Responses To A Battling Rope Protocol Performed In The Seated Or Stance Positions, Dominisha Felder, Kasey Hogan, Reka Kovacs, Hannah Mitchell, Wayne Brewer

International Journal of Exercise Science: Conference Proceedings

Achieving the recommended amount of physical activity is a greater challenge for individuals who are disabled than those who are not disabled. Battling ropes is an intense exercise that has been shown to promote elevation of heart rate and increased oxygen consumption, and may be a beneficial exercise alternative for individuals with disabilities. PURPOSE: To compare the levels of perceived exertion (RPE), oxygen consumption (VO2) and heart rate (HR) responses elicited by a treadmill (TM) or bicycle (BK) VO2 max test with a standing or sitting battling rope protocol (BRP) (TM vs. standing BRP) (BK vs. …

Fico, Ryan S. Garten, Michael C. Zourdos, Michael Whitehurst, Peter J. Ferrandi, Katelyn M. Dodge, Gabriel Pena, Alexandra A. Rodriguez, Chun-Jung Huang Feb 2018

The Comparison Of High-Intensity Interval Exercise Vs. Continuous Moderate-Intensity Exercise On C1q/Tnf-Related Protein-9 Expression And Flow-Mediated Vasodilation In Obese Individuals, Brandon G. Fico, Ryan S. Garten, Michael C. Zourdos, Michael Whitehurst, Peter J. Ferrandi, Katelyn M. Dodge, Gabriel Pena, Alexandra A. Rodriguez, Chun-Jung Huang

International Journal of Exercise Science: Conference Proceedings

PURPOSE: A recent novel adipocytokine, C1q/TNF-related protein-9 (CTRP9), has been shown to increase activation of endothelial nitric oxide synthase and reduce vasoconstrictors (e.g., endothelin-1). In addition, CTRP9 may play a compensatory role in obesity-related endothelial dysfunction. Although there is limited information regarding exercise-mediated CTRP9, high-intensity interval exercise (HIIE) has been shown to be as or more effective than continuous moderate-intensity exercise (CME) in improving indicators of endothelial function (e.g., brachial artery flow-mediated dilation [BAFMD]). Therefore, the purpose of this study was to investigate the effect of acute HIIE vs. CME on serum CTRP9 and BAFMD responses in obese individuals. METHODS: …
