High-Intensity Acute Exercise And Directed Forgetting On Memory Function, Mary Elizabeth Pace, Paul D. Loprinzi

Faculty and Student Publications

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. Background and Objectives: Despite accumulating research demonstrating that acute exercise may enhance memory function, very little research has evaluated whether acute exercise can effectuate intentional directed forgetting (DF), an adaptative strategy to facilitate subsequent memory performance. Materials and Methods: A three-arm parallel-group randomized controlled intervention was employed. Participants were randomized into one of three groups, including: (1) exercise plus DF (Ex + DF), (2) DF (directed forgetting) only (DF) and (3) R (remember) only (R). The acute bout of exercise included 15 min of high-intensity treadmill exercise. The memory assessment involved …

Faculty and Student Publications

© 2019 American Osteopathic Association. Context: Osteoporosis is characterized by low bone mineral density (BMD) and has been thought to only be a major health concern for postmenopausal women. However, osteoporosis and its risk factors have been greatly understudied in the middle-aged and male populations. Objective: To assess the likelihood of low BMD and its association with related risk factors in early–middle-aged (defined in this study as 35-50 years) men and women.Methods: Eligible men and women completed a questionnaire assessing calcium intake, hours per week of exercise, and other related risk factors associated with osteoporosis and osteopenia. The primary outcome …

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

How To Help People Float, Andrea Andrews

International Journal of Aquatic Research and Education

This manuscript examines how to help more people learn to float because this skill is taking a much more central role in the latest drowning prevention advice in the UK. In 2017 BBC Radio Two show presenter, Simon Mayo, declared that he ‘could not float.’ Many persons in the UK identified with this claim. Despite having been an activity in many traditional swimming lessons floating is not a straight-forward skill for all to master. It requires a high degree of personal trust to have developed in the water. I discuss what learning to float fundamentally entails based on recent publications …

Leaving A Legacy: Empowering Students To Give Back, Eric Schutter

Honors Theses

Most college universities struggle to convince alumni to give back to their former institutions. Currently, only 19.9% of college alumni give back to their former colleges (Alumni Factor, 2018). Despite the amount of time and energy that schools invest in their students, many of the students are not making any sort of commitment in return. However, there is a solution. If college programs found ways to create avenues for students, both current and former, to give back outside of just university general funds, they could see an increase in student giving from both parties. While there is a notion that …

Exercise Cerebral Blood Flow Hemodynamics Differ In Hot Dry And Humid Conditions, Julianna J. Kilpatrick, Paolo Miguel Salvador, Kyleigh Allie, Eric Rivas

International Journal of Exercise Science: Conference Proceedings

Passive and exercise-heat stress have been reported to cause reductions in cerebral blood flow (CBF); however, it is unknown if CBF velocity is different under hot dry and humid conditions. PURPOSE: This project tested the hypothesis that upright rest and exercise-heat stress in hot dry and humid conditions result in similar CBF reductions. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO₂max: 52±10 mL/kg/min) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min of exercise at a rate of perceived exertion (RPE) of 12 (between light and somewhat hard) on a …

Attenuated Pulsatile Load During Metaboreflex Activation Is Associated With Excess Adiposity In Dynapenic Postmenopausal Women, Arun Maharaj, Salvador Jaime, Stephen Fischer, Arturo Figueroa

International Journal of Exercise Science: Conference Proceedings

The age-related loss in muscle strength (dynapenia) is associated with elevated blood pressure (BP) and fat mass (FM). Aortic pulse pressure (PP), rather than brachial PP, more closely relates to cardiovascular events because it represents left ventricular pulsatile load, which is particularly important in older women. Purpose: To examine the impact of dynapenia and adiposity on aortic BP responses to metaboreflex activation (post-exercise muscle ischemia, PEMI) in postmenopausal women. Methods: 71 postmenopausal women [(dynapenic, n=41, 57±1 years), (non-dynapenic, n=30, 59±1 years)] were included in this study. FM, percent body fat (BF%) and percent lean mass (LM%) were measured using Dual …

Lower Leg Lean Mass Is Associated With Reduced Pulse Pressure Amplification In Postmenopausal Women, Stephen M. Fischer, Salvador J. Jaime, Arun Maharaj, Arturo Figueroa

International Journal of Exercise Science: Conference Proceedings

Sarcopenia, the age-related loss of skeletal muscle mass, has been associated with increased arterial stiffness (pulse wave velocity, PWV). Lower leg muscle mass has been associated with increased brachial-ankle PWV (baPWV), a measure of systemic arterial stiffness. Pulse pressure (PP) is lower in the aorta compared to the brachial artery (PP amplification, PPA), in healthy individuals. PPA decreases with aging due to increased aortic stiffening. Lower PPA is an independent predictor of cardiovascular death. It is unknown whether leg muscle mass is associated with lower PPA in postmenopausal women. Purpose: To examine relationships between leg lean mass (LegLM), PPA, and …

Low Intensity Exercise Has Greater Acute Vascular Benefits For Reducing Arterial Stiffness In Hot Compared To Neutral Conditions, Kyleigh N. Allie, Julianna Kilpatrick, Paolo Salvador, Eric Rivas

International Journal of Exercise Science: Conference Proceedings

Both exercise and passive heating cause acute reductions in blood pressure. It is unknown if exercise-heat stress causes likewise reductions or greater when combined. PURPOSE: This project tested the hypothesis that the resting and exercise-heat stress cause hypotension and improvements in arterial stiffness. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO2max: 52±10 mL/kg/min ) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min at an exercise intensity of their choice that represented their perceived exertion (RPE) of 12 (between light and somewhat hard) on a 20-point rating scale while being blinded to …

Validity Of Body Volume Estimates From Infrared 3-Dimensional Scanning And Dual-Energy X-Ray Absorptiometry As Compared To Air Displacement Plethysmography, Marqui Benavides, Michael Moore, Jacob Dellinger, Claire Underwood, Tyler Dierolf, Brian Adamson, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Traditional methods of estimating body volume (BV) such as hydrostatic weighing and air-displacement plethysmography (ADP) could theoretically be replaced using BV estimates obtained by dual-energy x-ray absorptiometry (DXA) or infrared 3-dimensional (3D) scanning devices. Multiple 3D scanning technologies have recently become popularized, including scanners that acquire data through pattern deformations caused by the projected light over the 3D object (i.e., structured light [SL] scanners) or by calculating depth from the time it takes reflected photons to reach the scanner’s image sensor (i.e. time of flight [ToF] scanners). While these 3D scanning technologies currently predict body composition based primarily on circumference …

Skin Temperature And High Dew Point In Hot Environments Affects Self-Paced Exercise, Paolo Miguel Salvador, Julianna Kilpatrick, Kyleigh Allie, Eric Rivas

International Journal of Exercise Science: Conference Proceedings

Dew point (dp) is the absolute measure of water vapor and directly affects comfort whereas 5-10℃ feels dry; 10-15℃ feels comfortable and 20-24℃ feels uncomfortable. PURPOSE: This project tested the hypothesis that exercise in hot ambient conditions with a high dp (>20℃) would affect the selection of self-paced exercise compared to neutral dry conditions (dp). METHODS: Six healthy active (7 day activity: 9826±3900 steps/day; VO₂max: 52±10 mL/kg/min ) subjects (4M/2F, 25±9y, 171±6cm, 69±7kg) completed a 30 min baseline rest then 60 min of exercise intensity they chose that represents their perceived exertion of 12 …

Validity Of Four-Compartment Model Body Fat Using Single- Or Multi-Frequency Bioelectrical Impedance Analysis To Estimate Body Water, M. Lane Moore, Marqui L. Benavides, Jacob R. Dellinger, Brian T. Adamson, Claire P. Underwood, Tyler C. Dierolf, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Most common body composition assessment techniques make assumptions about the body, including the density and hydration of fat-free mass (FFM). An advantage of the four-compartment (4C) model is the ability to take these FFM characteristics into account when assessing body composition, thus reducing potential error. The total body water (TBW) estimate utilized in 4C models is particularly important due to the large contribution of water to an adult human’s total body mass (~40 - 70%) and FFM (~68 - 81%); however, the impact of utilizing different estimates of TBW within 4C model has not been fully explored. PURPOSE: The …

Comparison Of Regional Body Composition Estimates Obtained From Dual-Energy X-Ray Absorptiometry And Single-Frequency Bioelectrical Impedance Analysis, Jacob Dellinger, M. Lane Moore, Marqui L. Benavides, Tyler C. Dierolf, Brian T. Adamson, Claire P. Underwood, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

The anatomical distribution of fat mass (FM) and lean mass (LM) is significant for health and athletic performance. Dual-energy x-ray absorptiometry (DXA) is often used for regional body composition analysis but is not portable, often inaccessible, and costly, while single-frequency bioelectrical impedance analysis (SFBIA) is a more affordable and accessible alternative. PURPOSE: The purpose of this analysis was to compare regional body composition estimates obtained via DXA and SFBIA. METHODS: After an overnight food and fluid fast, 102 adults (64 F, 38 M; age: 29.2 ± 13.4 y; BMI: 24.3 ± 3.9 kg/m²; BF%: 24.6 ± …

Validity Of Infrared 3-Dimensional Scanning For Estimation Of Body Composition: A 4-Compartment Model Comparison, Brian T. Adamson, Jacob R. Dellinger, Marqui L. Benavides, M. Lane Moore, Claire P. Underwood, Tyler C. Dierolf, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Multiple infrared 3-dimensional (3D) scanning technologies exist, including time of flight (ToF) scanners and structured light scanners with static (SL-S) and dynamic (SL-D) configurations. ToF scanners measure depth by using the round-trip time of reflected photons, whereas SL scanners measure deformations in light patterns and allow for creation of a depth image using geometric triangulation. Recently, 3D scanning technologies have been proposed as novel methods of body composition assessment. PURPOSE: The purpose of this analysis was to examine the validity of four different commercially-available 3D scanners for estimation of body fat percentage (BF%) as compared to a 4-compartment (4C) …

Purposes for this investigation was to examine type of swimming instruction and ability to swim and compare to attitudes toward swimming among US youth. Methods were similar to previous USA Swimming studies in 2008 and 2010. YMCA associations in five cities were used to recruit adolescent survey respondents (n=600) aged 12-18 years. Results showed African American youth had the lowest rate of formal swimming instruction (29%) compared to White (32%) and Hispanic (42%) …

Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith

Faculty and Student Publications

© The Author(s) 2018. There is irrefutable evidence that regular participation in physical activity is favorably associated with numerous positive health outcomes, including cognitive function. Emerging work suggests that perceived physical activity, independent of actual physical activity behavior, is inversely associated with mortality risk. In this study, we evaluate whether perceived physical activity, independent of actual physical activity, is associated with cognitive function, a robust indicator of mortality risk. Data from the cross-sectional 1999–2002 National Health and Nutrition Examination Survey were employed (N = 2352; 60+ years of age). Actual physical activity was assessed via a validated survey. Perceived physical …
