The Effects Of Compression Garments And Extrinsic Visual Feedback On Single-Leg Balance Control, You-Jou Hung

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 4, 2022. Single-leg balance control is very important in injury prevention (such as reducing the chance of falls and ankle sprains) and sport performance. Although compression garments (CGs) have been used for various purposes, it is unclear if wearing CGs can improve single-leg balance in healthy individuals. The purpose of the study was to examine if wearing CGs (pants) could enhance single-leg balance, and to compare the impact of wearing CGs on single-leg balance between conditions with and without extrinsic visual feedback. Twenty-five healthy individuals (aged 20-30 years) participated …

Validation, Categorizing, And Prediction Of Upper Limb Outcomes After Stroke, Jessica Barth

Arts & Sciences Graduate Student Theses and Dissertations

The incidence and costs of stroke in the United States are projected to rise over the next decade because of the aging population. Declining stroke mortality over the past few decades means that more people survive stroke and live with physical, cognitive, and emotional disability. Stroke remains one of the leading causes of disability in the United States because very few survivors experience a full recovery of their upper limb. Upper limb recovery after stroke is critical to performing activities of daily living and physical and occupational therapies are one of the only treatment options to address these challenges. The …

The Effect Of Creatine Supplementation On Body Composition And Total Body Water Measured By Multi-Frequency Bioelectrical Impedance, Emily A. Buck

Masters Theses, 2020-current

Background: Acute fluid ingestion causes an increase in estimated body fat percentage (BF%) measurements by single frequency (SF-BIA) and multi-frequency bioelectrical impedance (MF-BIA). However, it is unknown if MF-BIA accurately measures total body water (TBW) and BF% after chronic fluid retention. Creatine supplementation causes fluid retention, and resultant increases in TBW and body mass. Research is needed to determine if MF-BIA is capable of detecting fluid retention secondary to creatine supplementation. Methods: 13 male and 14 female subjects (18-22 y) completed one week of creatine monohydrate or maltodextrin supplementation at a dose of 0.3 g/kg body weight. Subjects completed pre-supplementation …

For each initial graded exercise test, starting speed was 3.0 mph and increased by 0.5 mph every minute until 6.0 mph was reached. After this point, elevation was increased by 3.0% every minute until volitional exhaustion. VO_{2 …}

Does A Bout Of Acute Resistance Exercise Attenuate The Post-Prandial Lipemic Response To A High Fat Meal In 50-80 Year-Old Adults, Summer Simulcik

Masters Theses, 2020-current

Background: A single high-fat meal (HFM) is known to elevate blood lipid levels above what is normal, resulting in postprandial lipemia (PPL). Chronic hyperlipemia has been associated with increased risk for cardiovascular disease (CVD) and type-2 diabetes mellitus (T2DM) development. Current physical activity (PA) guidelines recommend at least one set of 8-12 repetitions of each exercise to attenuate this risk. Adults older than 50 (OF) years (y) are at an increased risk for cardiometabolic disease compared to younger adults (YA). Aerobic exercise (AE) performed in the pre-prandial period has been observed to attenuate PPL in both OF and YA. However, …

The Impact Of High- Vs. Low-Load Resistance Training On Measures Of Muscle Activation, Strength, Body Composition, And Hormonal Markers, Marissa Laina Bello

Theses and Dissertations

Resistance training has shifted towards a high- vs low-load training approach. Heavier loads are suggested to maximally recruit motor units and optimize strength adaptations, whereas lower loads stimulate hypertrophy. However, a majority of the research has not used a true strength range when assessing load. Therefore, the purpose of this investigation was to examine and determine significant differences in strength, body composition, and hormonal markers over nine weeks of high- or low-load resistance training. Secondary purposes of the current investigation were to assess and quantify training load for resistance training using sEMG sensor-embedded compression shorts. 17 recreationally-trained males were randomized …

Effects Of Acute Exercise On True And False Memory, Hanna Watson

The five counterbalanced visits included a control visit, vigorous-intensity exercise (80% of HHR; heart rate reserve) before encoding, vigorous exercise during encoding with no delay before encoding, vigorous exercise during encoding with a delay before encoding, and light-intensity exercise (30% of HHR) during encoding. A recognition task using the DRM (Deese-Roediger-McDermott) paradigm was used to evaluate true and false memory performance. Results: With hit rate as the outcome, there was …

Linking Spinal Cord Circuits With Upper Limb Sensorimotor Control In Adults With Cerebral Palsy, Saihari Dukkipati

Theses & Dissertations

Cerebral palsy (CP) is the most common neurological disorder originating in childhood, but most of the people living with CP are currently adults. While people with CP continue to get older, the amount of research focused on adults has been rather limited. The early childhood insults leading to CP are thought to originate in the brain, but the effects on the entire neuromuscular system across the lifespan have only recently started to be explored. Of note, recent neuroimaging evidence suggests that the cervical spinal cord structure is atypical in adults with CP. However, it is largely unclear how the neurophysiological …

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 …
