Effects Of Physical Characteristics Of Placebos On Exercise Performance, Owen Sipes

Human Movement Sciences & Special Education Theses & Dissertations

Previous research has shown that placebos can impact medical conditions such as irritable bowel syndrome and depression as well as elicit analgesic effects and improvements in certain exercise performances. These placebo responses occur from a variety of alterations to the placebo itself or through verbal suggestion of how helpful the placebo will be. This study aimed to observe whether changing the color and quantity of capsules can induce improvements in both vertical jump and hand grip strength. This deceptive, parallel study consisted of 28 participants, with a mean age of 24.9 (±4.3) years old, that were randomly assigned to receive …

Effects Of High-Speed Training On Messenger Rna Expression In Two-Year-Old Thoroughbred Racehorses, Mackenzie Grace Johnson

Theses and Dissertations--Veterinary Science

Accumulating high-speed exercise has been identified as a significant risk factor for catastrophic injuries in racing Thoroughbreds. Injuries, regardless of severity, are a main cause of withdrawal from the racing industry, raising animal welfare concerns and resulting in significant economic losses. While most of the current literature focuses on catastrophic injuries incurred during racing rather than training, the present study aims to help fill this gap as well as discuss the associated risk factors. The evaluation of messenger RNA (mRNA) expression changes provides an efficient and straightforward approach to identifying horses at risk for catastrophic injury. While alternative injury risk …

The Effects Of Cannabidiol Cream On Soreness And Performance After Exercise In Untrained Individuals, Joseph Thomas Pastina

Theses and Dissertations--Kinesiology and Health Promotion

Background: Exercise-induced muscle damage (EIMD) results from unaccustomed exercise and can lead to delayed onset muscle soreness (DOMS). Impairments associated with EIMD and DOMS can result in moderate-to-severe discomfort and hindered performance. Recently, a compound derived from the cannabis plant, cannabidiol (CBD), has been used as a recovery tool for EIMD and DOMS. Despite the rising popularity of CBD products, their effectiveness in mitigating EIMD and DOMS is unknown. Purpose: The purpose of the present study was to investigate the effects of CBD cream on DOMS and performance after an intensive lower-body exercise protocol. In addition, the study sought to …

Temporal Effects Of Acute Moderate Intensity Physical Activity On Working Memory Performance In Young Adults, Kimberly Loy Seibold

Graduate Theses and Dissertations

An ample amount of research suggests that increases in physical activity in young adults could help improve memory and cognitive functions which may aid in academic success (Johnson & Loprinzi, 2019; Perini et al., 2016). A sufficient working memory is critical to learning because it allows us to temporarily store and compare multiple informational items at one time to form a new concept or solve a problem (Cowan, 2013). The purpose of this study was to examine the temporal effects of acute moderate intensity physical activity on working memory in young adults. This study utilized a within-groups (repeated measures) cross-over …

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Fulghum

Electronic Theses and Dissertations

Regular aerobic exercise promotes physiological cardiac growth, which is an adaptive response thought to enable the heart to meet higher physical demands. Cardiac growth involves coordination of catabolic and anabolic activities to support ATP generation, macromolecule biosynthesis, and myocyte hypertrophy. Although previous studies suggest that exercise-induced reductions in cardiac glycolysis are critical for physiological myocyte hypertrophy, it remains unclear how exercise influences the many interlinked pathways of metabolism that support adaptive remodeling of the heart. In this thesis project, we tested the general hypothesis that aerobic exercise promotes physiological cardiac growth by coordinating myocardial metabolism to promote glucose-supported anabolic pathway …

The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias

Honors Theses

Previous research has indicated that aspects of cognitive inhibition may be enhanced after engaging in acute exercise. Notably, cognitive inhibition has been theorized as a potential mechanism for a form of active forgetting known as retrieval-induced forgetting (RIF). Given that cognitive inhibition may explain the RIF phenomenon, and is also influenced by exercise, it is plausible that acute exercise may directly influence RIF. To our knowledge, only one study has examined whether acute exercise has an effect on RIF. The findings of that study did not find a statistically significant effect for RIF; however, we believe that the rather small …

Self-Rated Function And Delayed Onset Muscle Soreness (Doms) Responses To 6-Week Supplementation With Waters With Anti-Inflammatory Capabilities (Wac), Kristin Garner

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: Researchers have examined the effects of sedentary lifestyles on diminished health outcomes and are pleading individuals to take on a more active lifestyle to prevent these. However, initial efforts to exercise are often dampened by delayed onset muscle soreness (DOMS) and muscle fatigue. This can greatly reduce exercise adherence, making it difficult for individuals to overcome this temporary discomfort. Background: Research has extensively evaluated nonsteroidal anti-inflammatory drugs (NSAIDs) and fruits as anti-inflammatory supplementation to treat DOMS. Berry-derived essences are more highly concentrated in anti-inflammatory substances than regular fruit juices, but there is minimal research on their effects on exercise …

Comparing Various Physiological System Adaptations Following 8 Weeks Of Resistance Training With Or Without Bfr In Older Males, Ricardo Parra

Theses and Dissertations

PURPOSE: The purpose of this study was to compare the effects of 8 weeks of resistance exercise training with and without BFR on: 1), arterial elasticity and hemodynamics (e.g., blood pressure and resting heart rate), 2) muscular force production (e.g., maximal voluntary contraction, force production, electromyography, and estimated one-repetition maximum) in males between the 50 to 70 years of age.

RESULTS: Significant condition difference for reflection magnitude occurred in BFR group (p < 0.05). Significant time*condition effect occurred in Leg Press 1RM, Leg Extension 1RM, Leg Curl 1RM, Chest Press 1RM, and Shoulder Press 1RM (p < 0.05). Significant condition* time interaction occurred for Isokinetic Leg Extension Test (60°/s) (p < 0.05). A significant time*condition interaction occurred during Maximal Voluntary Contraction (MVC) – Root Mean Square for both vastus medialis and vastus lateralis (p < 0.05). A significant time main effect occurred in the BFR group for the amplitude mean of the MVC in the vastus medialis and vastus lateralis (p < 0.05). A significant time main effect occurred for median frequency of the MVC (p < 0.05). A significant difference in Estimated Visceral Adipose Tissue occurred in the BFR group (p < 0.05). A significant condition*time interaction occurred in arm fat percentage (p < 0.05). The BFR group had significantly less fat tissue (%) in the left arm (p < 0.01) and in the right arm (p = 0.04). A significant time*main effect occurred in the total lean tissue for the left side of the body (p = 0.04).

CONCLUSION: Using BFR resistance training at a low intensity can achieve similar adaptations seen at high intensities while reducing the risk of injury that comes with heavier loads.

Effects Of A Remote Exercise Intervention On Aerobic Endurance In Individuals With Down Syndrome, Andrew Murata, Elena Wolf, Jonathan Crimm, Benjamin Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Down syndrome (Ds) or Trisomy 21 is a common genetic birth condition, and those with Ds typically display decreased cardiorespiratory fitness compared to those without Ds, potentially leading to an increased risk for cardiovascular conditions and mortality. Low cardiorespiratory fitness is partially caused by low physical activity levels in this population. The COVID-19 pandemic caused community-based activity programs to shut down, as individuals with Ds are at increased risk for COVID-19 hospitalization and death. Thus, it was vital to explore alternatives of in-person exercise during the pandemic. The purpose of this study was to investigate the effects of a …

Exercise As A Treatment For Cognitive Decline In Older Adults: The Role Of Growth Factors And Inflammatory Cytokines, Joshua A. Titus

Electronic Thesis and Dissertation Repository

The purpose of this thesis was to investigate the effects that exercise modalities have on neurotrophic and inflammatory blood markers and cognitive outcomes in older adults. A systematic review and meta-analysis were completed. The included studies illustrated that most of the literature evaluated the effect of aerobic exercise interventions on systemic concentrations of the blood marker brain-derived neurotrophic factor (BDNF). The review found that aerobic exercise increases BDNF and resistance training increases insulin-like growth factor 1 (IGF-1). Interventions with sex-specific cohorts presented advantages in males for blood marker and cognitive outcomes compared to females. One of three included interventions decreased …
