A Comparison Of Ground Reaction Forces And Muscle Activity Of The Tsunami Bar® Against A Rigid Barbell During Back Squat Phases, John Carver Middleton

Theses and Dissertations

An Institutional Review Board (IRB)-approved study was conducted to investigate the effects of the Tsunami Bar® (TB), a flexible barbell, on ground reaction force (GRF) production and muscle activity in the quadricep, hamstring, and gluteal muscle groups during phases of the squat exercise and compare the effects to the effects to using a rigid barbell (RB). A two-by-two repeated measures Analysis of Variance (ANOVA) test was used to compare the results. Descriptive statistics showed significantly higher GRFs for the TB during the unweighting phase, significant differences in GRFs between speeds for each phase, significantly higher forces on average with the …

The Benefits And Implementation Of Open Science Practices In Exercise Science Research, Brendan Moore

Senior Theses

This article has the purpose of addressing the need for open science practices in the field of exercise science research. Open science is best defined as the call for greater accessibility and transparency in research (Chakravorty et al., 2022). With more accessible and transparent research, research can be conducted more thoroughly and efficiently. Additionally, the implementation of these practices would discourage many shady and unethical practices. The idea of open science is not without debate however. There are many concerns over the theft of scientific data and ideas, as well as the increased time and monetary costs associated with many …

Examination Of Energy Needs In Male And Female Physically Active Individuals, Savanna Griffin

Senior Theses

Content: The Female Athlete Triad refers to three interrelated components: 1) low energy availability (LEA), with or without an eating disorder (ED); 2) harmful and physiologically impactful hormonal changes; and 3) alterations in bone mineral density, which are often experienced by individuals engaged in organized sports or other intense physical activities. This phenomenon is called the Female Athlete Triad because the relationship of components has thus far been observed primarily in females. A new term, the Male Athlete Triad, has been recently developed to describe the same phenomenon in males. LEA occurs when dietary energy intake (EI) is inadequate to …

The Effect Of Chronic Alcohol Consumption On Exercise-Induced Muscle Damage In Young Men, Emma Hamilton, Grant Hilliard

Honors Theses

PURPOSE: To investigate the effects of chronic alcohol consumption on exercise-induced muscle damage of the knee extensors in young men. METHODS: Twenty-one males (age 21.9 ± 1.1 yr; weight 183.4 ± 27.6 lbs; height 174.0 ± 13.1 cm) performed 100 maximal eccentric contractions at 30°/sec of the knee extensors using their non-dominant leg. The isometric and isokinetic muscle strengths (60°/sec and 180°/sec) were measured pre-exercise and immediately, 24 h, 48 h, 72 h, 96 h, and 120 h post-exercise. Muscle soreness and plasma creatine kinase (CK) activity were measured pre-exercise and 24 h, 48 h, 72 h, 96 h, and …

Association Of Body Mass Index Genetic Risk Markers With Body Composition During Adolescence, Brice A. Smoker

Senior Theses

Background. Obesity affects nearly a fifth of all children in the United States and is a common risk factor for numerous chronic diseases. Many risk factors contribute to obesity, including race and genetics. Obesity is partially heritable, and many genetic loci have been identified as being associated with body mass index (BMI) in adults. Some of these loci have also been associated with childhood BMI, with effects strengthening with age. A previous genome-wide association study (GWAS) identified five single nucleotide polymorphisms (SNPs) associated with changes in BMI in children aged 1 – 17 years.

Purpose. The purpose of the current …

Comparison Of Muscle Physiology And Performance Outcomes From Either Relative Intensity Or Repetition Maximum Training, Kevin Carroll

Electronic Theses and Dissertations

The main purpose of this dissertation was to compare performance and physiological outcomes of between a repetition maximum (RM) and a relative intensity using sets-and-repetitions (RI_SR) resistance training (RT) program in well-trained lifters. Fifteen subjects underwent RT 3 d·wk^-1 for 10-weeks in either a RM group (n=8) or RI_SR group (n=7). The RM group achieved a relative maximum each day while the RI_SR group trained based on percentages. Testing included percutaneous needle biopsies of the vastus lateralis, ultrasonography, unweighted (g to assess within and between-group alterations. RI_SR from pre-to-post yielded statistically significant increases in …

The Effects Of Land-Based Plyometric Training And Timing Of Plyometrics Fusion On Selected Acute Swim Performance Measures, Joshua R. Beard

Theses & Honors Papers

The purpose of this study is twofold: 1) to determine the effect of land-based plyometric training on selected acute swim performance measures; and 2) to determine the effect of timing on acute swim performance measures when incorporating plyometric training into a single training session. The guiding hypothesis for this project is that the land-based plyometric training will have a positive impact on acute swim performance, in particular when the plyometrics are performed pre-training session (compared to mid-training session).
