Examining The Effects Of Exercise-Induced, Physical Stress Overtraining On Stress Biomarkers In Adolescent, C57bl/6 Mice, Curtis Scotty Davis

Theses, Dissertations and Capstones

Exercise has long been established as a therapeutic modality to improve health and related physical fitness, sports performance, and injury/risk reduction in both adults and adolescents (Haff & Triplett, 2015; Kaminsky, 2010). Nonetheless, there is a lack of research investigating the negative effects of exercise overstress (i.e., overtraining syndrome) in these populations, particularly adolescents (Brenner & American Academy of Pediatrics Council on Sports Medicine and Fitness, 2007; Matos & Winsley, 2007). The objective of this study was to examine hormone biochemical markers, anthropometric markers, and behavioral traits, which are associated with overtraining syndrome, in adolescent C57BL/6 mice. A total of …

Perceived Exertion And The Increase In Risk Of Injury In Rotc Cadets, Courtney D. Chiaramonte

Theses, Dissertations and Capstones

Context: Musculoskeletal injury in military personnel creates problems due to economic losses, and decreased training. The repetitive motions associated with military training and the daily physical training sessions can lead to the development of fatigue. Fatigue has been shown to contribute to 18% - 26% of musculoskeletal injuries. [7] Several studies have explored fatigue as a risk of injury during occupation. Fatigue has been shown to increase the perceived effort during physical exercise. The purpose of this study was to characterize the perception of effort during physical training sessions and injury rates in ROTC cadets throughout an academic year.

The Anatomy Of The Carpal Tunnel And Hand Function Of Musicians, Emily Ann Lorenzen

Theses, Dissertations and Capstones

Musicians spend hours perfecting their trade, often leading to overuse injuries of the hand; of specific concern to musicians is carpal tunnel syndrome (CTS). This study evaluated the median nerve cross-sectional area and hand function of musicians and non-musicians. Patients completed the upper extremity and CTS specific function questionnaires. The median nerve cross-sectional area, and the width of the carpal tunnel were measured on ultrasound image. The median nerve cross-sectional area was greater in musicians than the non-musician group. The width of the carpal tunnel did not differ between the groups. Musicians showed higher levels of hand dysfunction than the …

The Effects Of Flexor Pronator Mass Fatigue On Medial Elbow Stability, Nathaniel Harvey Millard

Theses, Dissertations and Capstones

Introduction: The medial elbow is supported from valgus loading with the ulnar collateral ligament (UCL), the flexor pronator mass (FPM), and the radial head. Fatigue of muscle can lead to a decrease in force production. The decrease in force production can lead to a decrease in joint stability. This study tested the effect of fatigue of the FPM muscles on the width of the medial joint space.

Methods: Thirty-one participants volunteered for this study (18 female and 12 male, 1 excluded; mean height 170.2±10.1 cm, mean weight 71.2±15.6 kg, mean age 21.53±1.87 years old). Ultrasound images of the width of …

Examination Of Two Hydration Protocols During Simulated Forced Marching Under Acute Heat Stress, David Alan Cottrill

Theses, Dissertations and Capstones

The purpose of this study was to identify and compare the effects of ingesting either water or 6% solution of carbohydrates, electrolytes, and water on hydration status during simulated military road marching in hot environmental conditions. Five volunteer male subjects completed two 60 minute experimental trials exercising at a high intensity (RER .90-.95) in an improvised environmental chamber (29.7 ^{_{+ or -}} .18^oC, 11.3 + or - 2.13% relative humidity) in full army combat uniform carrying 18.18kg of equipment. Random assignment of either water or solution was completed prior to trial 1, and consumption of the unselected protocol …

Isokinetic Dynamometer Versus A Multi-Axial Stability Platform In The Proprioception And Strength Training Of The Peroneal Muscle Group, Eric Johnson

Theses, Dissertations and Capstones

Ankle injuries are the most common and frequent occurring injuries in sports today (Feuerbach, Grabiner & Koh, 1994). Ankle sprains usually occur in athletes that are participating in running or jumping activities. Injuries to the ankle joint represent about 20% of all sports related injuries, and 15% of all time lost injuries (Payne, Berg, & Latin, 1997). The majority of the sprains to the ankle occur to the lateral ligamentous structures due to the forcefully plantar flexion and inversion of the talocrural joint. This inversion mechanism accounts for 85% of all ankle sprains (Kinzey, Ingersoll, & Knight, 1997). Often after …

The Difference In Pain Tolerance Between Ncaa Division 1-A Male And Female Athletes, Mollie K. Karabatsos

Theses, Dissertations and Capstones

How well an athlete tolerates pain may aid the athletic trainer in determining a proper rehabilitation protocol for the quickest recovery and return to play after an injury. The present investigation was conducted to determine if there is a difference in pain tolerance between NCAA Division I-A male and female athletes. The subjects consisted of nineteen healthy Division I-A male athletes and nineteen healthy Division I-A female athletes all between the ages of 18 and 23 (N=38). The subjects placed their hand, up to their styloid process, into a one - degree Celsius ice bath for one minute. After one …
