Effects Of Knee Sleeves On Knee Mechanics During Squats At Variable Depths, Alexandria A. Trypuc

Human Movement Studies & Special Education Theses & Dissertations

The squat is a functional, compound and multi-joint exercise that targets several muscles of the lower body and is widely used in both athletics and many exercise programs. This exercise has been the subject of many studies, comparing different squat variations and examining how external gear, such as squat suits and knee wraps impact the exercise. The aim of this study was to assess the effects of wearing neoprene knee sleeves on lower extremity kinematics, kinetics, and muscle activations during weighted back squats. Fifteen resistance trained men and women, aged 28±5 years, from the local fitness community and university campus …

Role Of Brain Derived Neurotrophic Factor (Bdnf) In Stimulating Strength Improvements Induced By Short-Term Resistance Training, David Church

Electronic Theses and Dissertations

Strength adaptations from short-term resistance training are thought to be related primarily to neurological adaptations. Considering brain-derived neurotrophic factor (BDNF) role in the nervous system, it is possible that BDNF has a role in these adaptations. Fourteen untrained males were randomized into either a resistance training (RT; n =8) or control (CON; n=6) group. Motor unit (MU) recruitment at 50% and 80% of each participant's maximal voluntary isometric contraction (MVIC), muscle cross sectional area (CSA) and thickness (MT), as well as one-repetition maximum (1RM) of the squat (SQT), leg press (LP), and leg extension (LE) were performed before (PRE) and …

Examining Work-To-Rest Ratios To Optimize Upper Body Sprint Interval Training, Michael La Monica

Electronic Theses and Dissertations

The primary purpose of this study was to compare the metabolic influence of varying work-to-rest ratios during upper body sprint interval training (SIT). Forty-two recreationally trained men were randomized into one of three training groups [10s work bouts with two minutes of rest (10:2, n = 11) or four minutes of rest (10:4, n = 11), or 30s work bouts with four minutes of rest (30:4, n = 10)] or a control group (CON, n = 10). Participants underwent six training sessions over two weeks with four to six 'all-out' sprints. During pre- and post-intervention visits, participants underwent a graded …

The Effects Of Two Different Sports Drinks On Rpe And Finishing Speed Of An Endurance Run In Highly Trained Distance Runners, Matthew J. Feldhake

Masters Theses

The purpose of this study was to compare the effects of a protein-containing sport drink with a traditional non-protein sport drink has on ratings of perceived exertion (RPE) and finishing speed of an half marathon. Of the possible factors that would support including protein in a sport drink the primary one was its inhibitory effect on serotonin release in the brain. This could help attenuate perceived exertion, thus allowing individuals to compete at a higher level for longer durations (Davis, Alderson, & Welsh, 2000).

This study was conducted using nine members of the Eastern Illinois University Men's Cross Country team. …

Exercise Dependence And Shin Pain In A Division I Cross-Country Runner: A Case Study, Allyssa K. Memmini

Clinical Practice in Athletic Training

The following case investigates insidious onset of shin pain in a Division I female cross-country runner. Though her initial evaluation revealed early onset medial tibial stress syndrome, the sequence of events that occurred immediately afterwards is what makes this case unique. As the student-athlete underwent lower extremity rehabilitation to increase her mileage, she reported that her pain had plateaued. The initial x-ray revealed a periosteal reaction of the posterior left tibia. After adhering to the treatment plan for four weeks, the student-athlete continued to report significant bouts of pain as demonstrated by the Visual Analog Scale. A follow-up x-ray revealed …

Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks

Theses and Dissertations

Atherosclerotic cardiovascular disease (CVD) is hallmarked by inflammatory immune activation, particularly by the induction of a response by monocytes. Classical (CD14⁺⁺CD16^-) are anti-inflammatory mediators under homeostatic conditions, while intermediate (CD14⁺⁺CD16⁺) and non-classical (CD14^LowCD16⁺⁺) monocytes promote inflammation following activation. Monocyte activation and functionality is dependent upon receptor expression and ligand production by a variety of cells, including monocytes. Alterations in the expression of surface receptors often have a direct impact upon monocyte function, such as the increased pro-inflammatory cytokine production in response to activation that accompanies elevated CD14 expression …

Examining The Effects Of Interleukin-6 On Appetite Regulatory Peptides In Lean And Obese Sedentary Males, Greg L. Mckie

Theses and Dissertations (Comprehensive)

Acute moderate-intensity exercise transiently suppresses appetite via fluctuations in the appetite-regulatory peptides acylated ghrelin (AG), peptide tyrosine-tyrosine_3-36 (PYY_3-36), and active glucagon-like peptide-1 (GLP-1). Importantly, these effects do not lead to compensatory changes in energy intake in normal weight or obese individuals, highlighting the potential for exercise to induce acute energy deficits. One potential mechanism for these effects is increased post-exercise plasma concentrations of interleukin (IL)-6, as IL-6 has demonstrated appetite-inhibitory effects in animal and cell culture models. Given obesity is characterized by a state of chronic low-grade inflammation and associated with upregulated IL-6, this study sought to …

Influence Of Maturation Status On Eccentric Exercise-Induced Muscle Damage And The Repeated Bout Effect In Females, Ming-Ju Lin, Kazunori Nosaka, Chih-Chiao Ho, Hsin-Lian Chen, Kuo-Wei Tseng, Sebastien Ratel, Trevor Chung-Ching Chen

Research outputs 2014 to 2021

This study compared changes in indirect muscle damage markers, proprioception and arterial stiffness after elbow flexor eccentric exercise between pre-pubescent (9–10 y), pubescent (14–15 y), and post-pubescent (20–24 y) healthy, untrained females (n = 13/group). The maturation of the participants was confirmed by the hand bone age. All participants performed two bouts of 30 sub-maximal eccentric contractions (EC1, EC2) using a dumbbell set at 60% of pre-exercise maximal voluntary isometric elbow flexion strength at 90°. Changes in maximal voluntary concentric contraction (MVC) torque, muscle soreness (SOR), plasma creatine kinase activity, proprioception (position sense, joint reaction angle) and arterial stiffness …

The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio

International Journal of Exercise Science

International Journal of Exercise Science 10(8): 1275-1296, 2017. Compared to investigations on hypocaloric diets, the effects of chronic overfeeding have been less studied. It has been posited that consuming calories in excess of daily caloric requirements will result in a gain in body weight and in particular fat mass regardless of which macronutrient(s) are consumed. However, recent evidence suggests that there is a quantitative difference in protein versus carbohydrate and/or fat overfeeding as it relates to body composition. Protein overfeeding or the consumption of a high protein diet may not result in a gain in body weight or fat mass …
