The Effects Of A Loaded Pre-Competition Activity Using Tethered Swimming On 25-Yard Swim Sprint Performance 2021, Jacob Burchfield
Master's Theses
Warmup is a standard practice for swim competitions, but there is minimal scientific evidence regarding the effectiveness of pre-competition activities (PCA) after the swim warmup. This study examined whether a loaded PCA using tethered swimming while attached to a power rack improves performance in a 25-yard swim sprint. Post activation performance enhancement (PAPE) may be the proposed mechanism for improvement resulting from a loaded PCA. To determine if PAPE existed following the loaded PCA, varsity swimmers from SUNY Cortland performed a 25-yard sprint a loaded PCA and after an unloaded PCA (control). All participants performed a standard meet warmup (1600-yards) …

Effects Of Different Stretching Modalities On The Antagonist And Agonist Muscles On Isokinetic Strength And Vertical Jump Performance, Samuel Montalvo
Open Access Theses & Dissertations
Warm-ups are essential components of all training sessions, sports, and physical activities. Warm-ups are typically composed of a variety of stretches. Two stretching modalities that are commonly performed before any physical activity are the static and dynamic stretching modalities. Historically, static stretching has been used as a preferred stretching modality during the warm-up period. However, research indicates that static stretching â?? if done prior to the training session â?? may inhibit the expression of muscular strength, muscular activation, and vertical jump height. On the contrary, dynamic stretching has been shown to improve the expression of muscular strength, muscular activation, and …

The Physiological Effects Of Therapy Dogs During Exercise For Sedentary Adults, Josie Lynne Mazzone
All NMU Master's Theses
Previous research has shown therapy dogs may be utilized to attenuate heart rate (HR) and blood pressure (BP) responses during various types of stressors due to an increase in oxytocin (OT) and decrease in cortisol (CL) production. These hormonal changes have also been shown to enhance exercise performance. Purpose: This study aimed to determine if physiological responses to exercise changed in the presence of a therapy dog for sedentary adults. Methods: Seven adult subjects (mean age of 30.86 ± 14.07 years) who self-reported less than 150 min of physical activity per week participated in a graded walking test with a …

Investigating Mechanisms In Nociceptors Driving Ongoing Activity And Ongoing Pain, Elia Lopez
Dissertations and Theses (Open Access)
Ongoing (apparently spontaneous) pain at rest is a major complaint of patients suffering from many forms of acute and chronic pain, including acute and persistent postsurgical pain. Accumulating evidence suggests ongoing activity in nociceptors is a major driver of ongoing pain. Ongoing activity can be generated in sensory neurons in the absence of sensory generator potentials if one or more of three neurophysiological alterations occur – prolonged depolarization of resting membrane potential (RMP), hyperpolarization of action potential (AP) threshold, and/or increased amplitude of depolarizing spontaneous fluctuations of membrane potential (DSFs) to bridge the gap between RMP and AP threshold. Cellular …

The Role Of Nutrition And Hormone Signaling In Extended Larval Development And Obesity In Starvation-Selected Drosophila Melanogaster, Jennifer M. Clark
UNLV Theses, Dissertations, Professional Papers, and Capstones
Brief periods of starvation are a common stressor that most animals encounter in the wild and must be able to survive in order to maximize their fitness. Starvation resistance of the adult fruit fly, Drosophila melanogaster, is thought to be primarily conferred by adult fat stores, body size, metabolic rate, behavior, and activity levels. Additionally, flies selected for starvation resistance also often show delayed pupariation, which is usually indicative of altered hormone signaling. How starvation selection extends development and if it contributes to adult starvation resistance remains incompletely studied. Identifying the targets of starvation selection that cause extended development and …

Validation Of A Novel Trpm8 Knockout Mouse Model, Bilan Mohamed
Thinking Matters Symposium
Recent studies suggest that the use of thermoregulatory treatments that affect brown fat may help curb obesity. However it is unknown how these treatments may affect bone homeostasis. Our work has focused on the transient receptor potential melastatin (TRPM8) protein, which is responsible for detecting colder temperatures in sensory neurons. Previous work within the Motyl laboratory has found that Trpm8 plays a role in bone acquisition. Mice with a global deletion of the Trpm8 gene have reduced trabecular bone volume fraction due to reduced bone formation by osteoblasts. However, it is unclear whether sensory neuron or osteoblast-mediated expression of Trpm8 …
The Effects Of Acute Exercise On Retrieval Induced Forgetting,

The Effects Of Acute Exercise On Retrieval Induced Forgetting, Walter Simpson
Honors Theses
Retrieval Induced Forgetting (RIF) is a type of active forgetting that may play beneficial and detrimental roles in long-term memory. The benefit of the retrieval of certain information is that information will become more readily available following subsequent retrieval; a concept termed the retrieval practice effect (RP). The detrimental effect of RIF may be that, upon the subsequent recall of certain information, related information may be inhibited from recall. The effects and mechanisms of RIF have remained a topic of debate among neuroscientists, psychologists, and other related scholars. The goal of this study was to evaluate the effects of acute …

International Journal of Exercise Science
International Journal of Exercise Science 14(4): 606-612, 2021. Researchers and strength and conditioning practitioners have had an increased interest in the effects of interlimb asymmetries on different aspects of sport performance over the past couple of years. Interlimb asymmetries have been found to negatively affect performance in key performance indicators (KPI) such as jumping, sprinting, and changing directions, within various sports populations. However, there is no consensus about a meaningful threshold at which asymmetries start to negatively affect KPIs or performance. The aim of this study was to investigate a potentially meaningful threshold for three asymmetry metrics (mean peak velocity …

Ecophysiological Responses Of Two Closely Related Epigean And Hypogean Niphargus Species To Hypoxia And Increased Temperature: Do They Differ?, Tatjana Simčič, Boris Sket
International Journal of Speleology
Ecological performance of animals depends on physiological and biochemical processes that are adjusted to the environment. The responses to hypoxia or anoxia have been frequently studied in subterranean aquatic organisms in order to find potential adaptations to restrict oxygen conditions occurring in the underground habitats. However, some previous studies have compared phylogenetic distant epigean and hypogean species or the epigean and hypogean populations of the same species due to little chance to compare closely related epigean and hypogean species. Therefore, in this study, we compared the effects of exposure to hypoxia, followed by reoxygenation, and increased temperature on oxygen consumption, …

Lower Limb Force Asymmetries During Landing And Jumping Exercises: A Pilot Study, Simon M. Cone, Sangwoo Lee
International Journal of Exercise Science
International Journal of Exercise Science 14(1): 544-551, 2021. Significant asymmetries can exist between the lower limbs’ force production during the take-off phase of bilateral jumping exercises. Some studies have indicated that similar asymmetries can also exist during the landing phase. It has not been demonstrated if the magnitude of lower body asymmetry was similar between the landing (L) and take-off (TO) phases of bilateral jumping movements. The main purpose of this study was to compare the asymmetry measured during the L and TO phases of bilateral jumping exercises to determine if there was a difference in asymmetry between the phases. …

Heart Health: Lifestyle Factors That Influence Cardiovascular Well-Being, Holly K. Sawyer
Honors College Theses
Each year, one in every four deaths in the United States is a result of heart disease. As the leading cause of death among women and men from various ethnicities, heart disease may be overlooked when making everyday life decisions. As a group of genetic and behavioral conditions, heart disease is the number one killer of Americans. This may be due to the typical Western diet and daily life choices such as drinking alcohol or smoking tobacco. Heart diseases including atherosclerosis and coronary artery disease kill ten times more women than breast cancer (Lewis, et al., 2017). White men have …
