Effects Of A Basketball Match On Heart Rate Variability In Collegiate Intramural Players, Unobatsha Mbaiwa May 2026

Effects Of A Basketball Match On Heart Rate Variability In Collegiate Intramural Players, Unobatsha Mbaiwa

Master's Theses

Heart rate variability (HRV) is a standard non-invasive physiological marker used to asses the autonomic nervous system (ANS) function and cardiovascular adaptability. HRV reflects the natural variations in time between successive heartbeats (R-R intervals), which come as a result of the interaction between sympathetic and parasympathetic branches of the ANS (Shaffer & Ginsberg, 2017). Higher HRV compared to an individual's baseline is normally considered an indicator of greater parasympathetic (rest/digest) influence and more effective physiological recovery, whereas lower HRV relative to baseline is associated with sympathetic (fight/flight) dominance, fatigue, and increased physiological strain. Since the standardized HRV measurement criteria were …


Effects Of Ankle Weights On Metabolic Response And Muscle Activity On A Lower Body Positive Pressure Treadmill 2017, Saige Hupman May 2017

Effects Of Ankle Weights On Metabolic Response And Muscle Activity On A Lower Body Positive Pressure Treadmill 2017, Saige Hupman

Master's Theses

Lower body positive pressure (LBPP) treadmills are growing in popularity for rehabilitative use, as the benefits of exercising at partially supported body weight may induce faster recovery. It is unknown if there are certain practices that increase exercise intensity while maintaining positive effects of LBPP. Adding ankle weights when walking or running could increase intensity of rehabilitation programs while maintaining the comfort of supported body weight. PURPOSE: To measure metabolic response (VO2, RER, HR, Caloric expenditure), RPE, and lower limb electromyography (EMG) amplitudes of LBPP treadmill walking and running with and without ankle weights. METHODS: Sixteen participants (Age: 21.94 ± …


The Relationship Between Ratings Of Perceived Exertion And Heart Rate In Ncaa Division Iii Male Soccer Players 2017, Samuel J. Guider May 2017

The Relationship Between Ratings Of Perceived Exertion And Heart Rate In Ncaa Division Iii Male Soccer Players 2017, Samuel J. Guider

Master's Theses

Every sport has specific physical demands of the human body. The amount of physiological load that an athlete endures during a bout of exercise can be described as training load (TL). Accurate calculation of training loads within athletes is important when it comes to strength and power development, as well as injury prevention and monitoring fatigue. Common methods used to calculate training loads for athletes include rating of perceived exertion (RPE) based methods, heart rate (HR) based methods, rate of oxygen consumption (VO2) methods, and blood lactate methods. Specifically with NCAA male soccer athletes, HR based methods and RPE based …


The Effects Of Whole Body High-Intensity Interval Training On Collegiate Female Soccer Players 2016, Whitney Frary May 2016

The Effects Of Whole Body High-Intensity Interval Training On Collegiate Female Soccer Players 2016, Whitney Frary

Master's Theses

Soccer is considered a high intensity sport that requires a high level of both aerobic and anaerobic fitness. A whole body high-intensity interval training adaptation has been shown to benefit both of these systems over a short period of time. The purpose of this study was to examine the effects of a five week whole-body high intensity interval training program on female collegiate soccer players performance in speed, acceleration, agility, vertical jump, aerobic capacity, physical self perception, and physical enjoyment. Participants were from the SUNY Cortland women’s soccer team who participated in a five- week training protocol three days a …


The Effects Of A Four-Week Whole-Body High-Intensity Training Program On Female Athletes 2015, Lindsey Taylor May 2015

The Effects Of A Four-Week Whole-Body High-Intensity Training Program On Female Athletes 2015, Lindsey Taylor

Master's Theses

Purpose: The purpose of this study was to examine the aerobic benefits and changes in running economy (RE) following a fourweek whole-body high-intensity interval training (HIIT) program on an athletic female population. Participants: Fourteen female student-athletes volunteered to participate in the study. Design: Participants reported on two occasions for VO2max and RE testing and were divided into two training groups based upon baseline VO2max: Endurance (END; n=6) and HIIT (n=8). Participants completed 12 total training sessions. During each session, END completed 30 minutes of vigorous-intensity running, while HIIT completed a total of four minutes of whole-body intervals. Measures: Maximal oxygen …


Ischemia Impairs Vasodilation In Skeletal Muscle Resistance Artery, Kyle Remington Struthers Jun 2011

Ischemia Impairs Vasodilation In Skeletal Muscle Resistance Artery, Kyle Remington Struthers

Master's Theses

Functional vasodilation in arterioles is impaired with chronic ischemia. We sought to examine the impact of chronic ischemia and age on skeletal muscle resistance artery function. To examine the impact of chronic ischemia, the femoral artery was resected from young (2-3mo) and adult (6-7mo) mice and the profunda femoris artery diameter was measured at rest and following gracilis muscle contraction 14 days later using intravital microscopy. Functional vasodilation was significantly impaired in ischemic mice (14.4±4.6% vs. 137.8±14.3%, p<0.0001 n=8) and non-ischemic adult mice (103.0±9.4% vs. 137.8±14.3%, p=0.05 n=10). In order to analyze the cellular mechanisms of the impairment, a protocol was developed to apply pharmacological agents to the experimental preparation while maintaining tissue homeostasis. Endothelial and smooth muscle dependent vasodilation were impaired with ischemia, 39.6 ± 13.6% vs. 80.5 ± 11.4% and 43.0 ± 11.7% vs. 85.1 ± 10.5%, respectively. From this data, it can be supported that smooth muscle dysfunction is the reason for the observed impairment in arterial vasodilation.
