No Changes In Appetite Stimulating Hormones Following Swimming And Cycling Exercise Interventions, Brandon G. Fico, Mohammed Alkatan, Yuzi Zhang, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

Swimming is a favorable and ideal modality of exercise for individuals with obesity and arthritis as it encompasses a minimal weight-bearing stress and a reduced heat load. However, the available evidence indicates that regular swimming may not be effective in reducing body weight and body fatness. A current hypothesis is that exercise in cold water somehow stimulates appetite. PURPOSE: We determined the effect of swimming exercise training on fasting concentrations of ghrelin, insulin, leptin, and peptide YY in obese individuals with osteoarthritis. Cycling training was included as a non-weight bearing land-based comparison group. METHODS: Thirty-nine obese participants with …

Proprioception can be tested by excluding the visual sense and performing arm movements in a repetitive manner. An arm kinesthesiometer, used to test proprioception, is a device that measures the angle of movement around a joint in 1 degree increments and allows both active and passive movement. PURPOSE: The purpose of the study was to determine whether sighted individuals perform better than those with occluded sight (blindfolded) due to proprioceptive awareness. METHODS: For 1 week, 92 student subjects from a …

A Comparison Of An Aerobic Exercise Program And A Resistance Training Program On Cognitive Functioning In Healthy College Students, Samantha H. Gonzalez, Amber M. Shipherd, Tyler Farney

International Journal of Exercise Science: Conference Proceedings

Cognitive functioning declines begin occurring as early as 30 years of age. Research has found evidence that exercise influences cognitive functioning in elderly patients with Alzheimer's and dementia. However, while cognitive functioning has often been linked to academic achievement, there is a lack of research examining exercise and cognitive functioning in young and healthy populations. Furthermore, research has found both aerobic and resistance training can impact cognitive functioning, but there is a lack of literature comparing the impact of exercise mode on cognitive functioning. PURPOSE: To explore the differences between an aerobic and resistance training program on cognitive functioning …

Relationship Between Muscular Performance Changes And Increases In Body Mass During Overfeeding Plus Resistance Training, Christian Rodriguez, Robert W. Smith, Matthew T. Stratton, Patrick S. Harty, Baylor A. Johnson, Jacob R. Dellinger, Marqui L. Benavides, Bradley Vincent, Abegale D. Williams, Sarah J. White, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Two critical components of muscular performance are muscular strength (e.g., the maximal load that can be lifted for a given exercise) and muscular endurance (e.g., the maximal number of repetitions that can be performed at a given load). When seeking improvements in muscular performance, it is common to employ nutritional strategies that create an energy surplus and a resultant gain in body mass. Varying rates of body mass gain are often prescribed to optimize training adaptations, including improvements in muscular performance; however, the relationship between rate of body mass gain and muscular performance improvements, if any, is not entirely clear. …

The Effect Of Acute Consumption Of Overtime Essential Amino Acids Sports Drink On Delayed Onset Muscle Soreness In The Older Sedentary Population, Andi Johnson, Grant Wagner, Abraham Gomez, Jerene Yazzie, Klaudia Szych, Matthew A. Barlow Phd

International Journal of Exercise Science: Conference Proceedings

Essential amino acids are necessary for nutrition whether obtained by digestion of proteins or by oral supplementation of amino acids. The elderly experience loss of skeletal muscles and decrease in their strength and function, which can lead to poor quality of life. Increased quantity and quality of proteins stimulates muscle protein synthesis that can help combat this natural aging process. Purpose: The aim of this study was to see if consumption of essential amino acid drink high concentrations of leucin (2040 mg/serving) during exercise will attenuate the condition of Delayed Onset Muscle Soreness in the elderly. Also, we aimed to …

Relationship Between Rate And Composition Of Mass Gain During Overfeeding Plus Resistance Training, Robert W. Smith, Patrick S. Harty, Matthew T. Stratton, Jacob Dellinger, Marqui Benavides, Baylor A. Johnson, Abegale D. Williams, Sarah White, Christian Rodriguez, Bradley Vincent, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

A common goal among athletes is to gain additional body mass (BM), particularly fat-free mass (FFM), in order to improve muscle strength, power, and overall performance. Athletes typically undergo BM accretion over a specific period of time in conjunction with high-volume resistance training (RT) in order to preferentially gain FFM and promote concomitant muscular performance improvements. PURPOSE: The purpose of this study was to examine the relationship between the rate of BM gain and the proportion of BM gained as FFM versus fat mass (FM) during a 6-week period of overfeeding and resistance training. METHODS: 21 resistance-trained males …

The Effect Of Short-Term Adventure-Sport Curriculum On The Level Of Mental Toughness Of Undergraduate Students, Katie Moscati, Jordan Boyea, Andreas Stamatis, Steven Maynard

International Journal of Exercise Science: Conference Proceedings

Mental toughness (MT) has been associated with both higher academic and physical performance. Adventure sports studies involve exposure to exploratory and risk-taking activities aiming to facilitate positive psychological characteristics. Although such programs are frequently promoted for this purpose, there is lack of empirical evidence concerning the effects of such a curriculum on the levels of MT in undergraduate students. PURPOSE: To examine the efficacy of an adventure-sport curriculum on the levels of MT of freshmen, undergraduate students throughout their first semester in the program.

The Effects Of A Dynamic Warm-Up On Exercise-Induced Redistribution Of Monocytes And Natural Killer Cells, Mahmoud T. Elzayat, Emily C. Lavoy

International Journal of Exercise Science: Conference Proceedings

Proportions of leukocyte subsets in peripheral blood are altered post-exercise and return to baseline during recovery. This is caused in part by exercise-induced increases in stress hormones. Inclusion of a pre-exercise dynamic warm-up has been shown to decrease markers of cardiovascular stress during exercise. However, whether a warm-up can attenuate changes to the immune system with exercise has not yet been examined PURPOSE: To compare monocyte and natural killer (NK) cell mobilization following a bout of high intensity aerobic exercise with and without a dynamic pre-exercise warm-up. METHODS: 16 physically active adults (7 women, 27.8±4.4 years) cycled 30 …

Influence Of Acute Water Ingestion On Bioelectrical Impedance Analysis Estimates Of Body Composition, Jacob R. Dellinger, Baylor A. Johnson, Matthew T. Stratton, Patrick S. Harty, Marqui Benavides, Sarah White, Abegale D. Williams, Robert W. Smith, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Body composition estimation is a significant component of health and fitness assessments. Multi-frequency bioelectrical impedance analysis (MFBIA) uses multiple electrical frequencies that travel through body tissues in order to estimate fluid content and body composition. Prior to body composition assessments, it is common to implement a wet fast (i.e., a fasting period that allows water intake); however, the influence of a wet fast as compared to a dry fast (i.e., disallowing water intake) is relatively unknown. PURPOSE: To determine the effects of acute water consumption on MFBIA body composition estimates. METHODS: A randomized crossover study was conducted in …

Bioactive Growth Hormone In Humans: Controversies, Complexities And Concepts, Wesley C. Hymer, Mary J. Kennett, Samir K. Maji, Kristin L. Gosselink, Gary E. Mccall, Richard E. Grindeland, Emily M. Post, William J. Kramer

Health and Sport Sciences Faculty Scholarship

Objective: To revisit a finding, first described in 1978, which documented existence of a pituitary growth factor that escaped detection by immunoassay, but which was active in the established rat tibia GH bioassay.

Methods: We present a narrative review of the evolution of growth hormone complexity, and its bio-detectability, from a historical perspective.

Results: In humans under the age of 60, physical training (i.e. aerobic endurance and resistance training) are stressors which preferentially stimulate release of bioactive GH (bGH) into the blood. Neuroanatomical studies indicate a) that nerve fibers directly innervate the human anterior pituitary and b) that hind limb …

Determinants Of Low Bone Mineral Density In People With Multiple Sclerosis: Role Of Physical Activity, Brice T. Cleland, Paula E. Papanek, Benjamin A. Ingraham, April L. Harkins, Mauricio Garnier-Villarreal, Douglas Woo, Mary Ellen Csuka, Alexander V. Ng

Exercise Science Faculty Research and Publications

Background

People with multiple sclerosis (PwMS) have reduced bone mineral density (BMD), but the causes are unclear. Some factors that may cause reduced BMD in PwMS have been understudied, including physical activity, inflammation, cortisol, symptomatic fatigue, and depression. The aim of this study was to investigate factors that may uniquely contribute to reduced BMD in PwMS as compared to people without MS. We hypothesized that physical activity would be the primary determinant of low BMD in PwMS, with additional contributions from inflammation and sympathetic nervous system activation.

Methods

We tested 23 PwMS (16 women; median EDSS: 2) and 22 control …

Human Physiology Faculty Scholarship

Comfort is a major criterion for footwear selection. Previous studies have suggested that physical properties were not enough to predict comfort and psychological factors could also affect the perception. To understand comfort, this study examined the effect of controlled shoe description and price cue on the perception of comfort. Furthermore, this study also examined the running biomechanics in response to footwear conditions of differing comfort. Fifteen runners completed treadmill running tests in two conditions: Shoe A and Shoe B. The same pair of neutral running shoes was used in both conditions, yet, Shoe B was described to be the “latest …

A Novel Item-Allocation Procedure For The Three-Form Planned Missing Data Design, Kyle M. Lang, E. Whitney G. Moore, Elizabeth M. Grandfield

Kinesiology, Health and Sport Studies

We propose a new method of constructing questionnaire forms in the three-form planned missing data design (PMDD). The random item allocation (RIA) procedure that we propose promises to dramatically simplify the process of implementing three-form PMDDs without compromising statistical performance. Our method is a stochastic approximation to the currently recommended approach of deterministically spreading a scale's items across the X-, A-, B-, and C-blocks when allocating the items in a three-form design. Direct empirical support for the performance of our method is only available for scales containing at least 12 items, so we also propose a modified approach for use …

Sports And Talent Selection In Early Adolescence, Ahmet Uzun

Health Sciences

Early adolescence is the fastest development period between childhood and adulthood. It is understood that this situation is important in determining the differences between ages in terms of academic and sports studies in adolescence development. It should be remembered that differences in the motor power of individuals, especially in early adolescence (11-14 years), may affect athletes' athletic achievement and future athlete training levels.In this case, some physical fitness tests are required to better monitor the health and education levels of individuals in childhood and adolescence. It is seen that these tests are widely used especially in childhood and adolescence. In …

Acute Exercise On Memory Function: Open Vs. Closed Skilled Exercise, Justin Cantrelle, Grace Burnett, Paul D. Loprinzi

Faculty and Student Publications

© 2020 The Author(s). Background: Previous studies suggest that acute exercise may improve memory function. Few studies, however, have investigated the differential effect of the acute exercise movement patterns on memory. Such an effect is plausible, as research demonstrates that open-skilled exercise (e.g., racquetball) may have a greater effect on memory-related neurotrophins (e.g., brain-derived neurotrophic factors) when compared to closed-skilled exercise (e.g. treadmill exercise). A key distinction between open- and closed-skilled exercise is that open-skilled exercises are those that require an individual to react in a dynamic way to a changing, unpredictable environment. Our aim in this study was to …
