Maturational Timing And Swim Performance In Collegiate Female Swimmers, Brian V. Wright, Andrew C. Cornett, Sierra Wagner, Alan Duski, Joel M. Stager

Kinesiology Faculty Publications

The purpose of this study was to determine if maturational timing is related to collegiate swim performance. Maturational timing was estimated using age at menarche (AaM), which was determined retrospectively in collegiate swimmers (N = 273). Each swimmer’s best performance during the 2015-2016 NCAA season was obtained from the USA Swimming database and selected based on Power Point Score (PPS), a standardized score given to all performances in the database. Independent samples t tests were used to compare (i) PPS and body mass index (BMI; from selfreported height and weight) between earlier maturing (youngest 33% at menarche) and later maturing …

The subject self-reported energy intake (EI) by reviewing his dietary plan following each stage. Basal metabolic rate (BMR) was estimated prior to the MdS …

Burrowing And Walking Mechanisms Of North American Moles, Yi-Fen Lin

Doctoral Dissertations

Moles (Family Talpidae) are a classic example of extreme specialization, in their case highly derived forelimb morphologies associated with burrowing. Despite many observations of mole burrows and behaviors gathered in the field, we know very little about how and how well moles use their forelimbs to dig tunnels and to walk within the built tunnels to collect and transport food. The first chapter investigates the effect of soil compactness on two sympatric mole species under controlled laboratory conditions. My results demonstrate that increasing soil compactness impedes tunneling performance as evidenced by reduced burrowing speed, increased soil transport, shorter tunnels, shorter …

International Journal of Exercise Science 10(3): 354-364, 2017. The aim of this study was to investigate the effects of six months of training with three different number of sets of resistance training on flexibility in young men. Forty-seven men (mean ± SD age = 24 ± 1yrs; body mass = 79.39 ± 9.12 kg; height = 174.5 ± 5.6 cm) were randomly divided into three training groups performing either one set (G1S), three sets (G3S), or five sets (G5S) of all exercises in a resistance training session or a control group (CG). All groups were assessed pre- and post-training for …

Does A Higher Motivation Score Predict A Bigger Increase In 2km Ergometer Times In Female Collegiate Rowers?, Kaitlyn Mchugh

Health Sciences Student Work

Introduction. A collegiate athlete’s schedule is typically busier than a college student, requiring time for practice, competition, training, as well as normal college student responsibilities. Because their schedules are so busy, athlete motivation is a key determinant for sustained and improved performance. Methods. This study was a pre and post correlation study. In fall 2016, participants completed a pre and post SMS-28 questionnaire and a 2km ergometer aerobic capacity test. Collegiate Female Rowing team was recruited with 13 participants (ages 18-22). 4 weeks later, 7 participants filled out the SMS-28 questionnaire, based on a Likert Scale, and performed the 2km …

Aerobic Capacity Is Related To Repeated Sprint Ability With Sprint Distances Less Than 40 Meters., Gabriel J. Sanders, Zachary Turner, Brian Boos, Corey Peacock, Willard Peveler, Alar Lipping

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 197-204, 2017 Research is inconclusive regarding the association between aerobic fitness (objectively measured VO_2max) and repeated sprint performance when the sprints are less than 40 meters. Soccer athletes must be able to repeat sprints without significant decreases in speed and strength and conditioning coaches need to better understand if aerobic fitness is related to repeated sprint ability (RSA). Twenty (10 male, 10 female) Division I soccer athletes first completed a graded maximal treadmill test to measure VO_2max. Then on a separate day, athletes completed the RSA test. The RSA test …

The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels

Electronic Theses and Dissertations

Background: Delayed onset muscle soreness (DOMS) is an exercise-induced muscle soreness resulting from high-intensity eccentric muscular contractions. DOMS appears to be more prevalent in athletes at the beginning of an athletic season or when new movements or exercise are first introduced. The acute effect of DOMS on jumping mechanics is currently unknown. PURPOSE: The purpose of this study is to determine the effect of delayed onset muscle soreness on vertical jump performance and jumping mechanics. METHODS: Twenty college aged, recreationally active males participated in this study (age: 21.54 ± 2.61; height: 1.82 ± 0.067; mass: 81.36 ± 9.53). Participants were …

BR effects on BP during submaximal exercise have not been investigated. Furthermore, the effects of BR on VO₂max are inconclusive. The purpose of this study was to investigate the effects of BR on VO₂max and BP during submaximal exercise. 20 healthy, recreationally trained volunteers (age 21.8±2.35 years, weight 75.10±10.62 kg, height 177.4±6.39 cm) participated in this study, which had a double-blind placebo controlled randomized crossover design. Participants began supplementation with either …

Effects Of A Post-Activation Potentiation Warm-Up On Submaximal Parallel Back Squat Volume, Rating Of Perceived Exertion, Peak Velocity, And Peak Power, Carlton Wei

Cal Poly Humboldt theses and projects

Resistance training (RT) is effective for improving athletic performance, with specific training loads and volumes dictating the adaptations. A warm-up is necessary to safely and effectively engage in RT: typically with a low intensity aerobic activity, stretching, and movement specific potentiating exercises. Post-activation potentiation (PAP) acutely increases muscular power following a conditioning contraction, though limited research has assessed its use for RT. The purpose of this study was to assess how a PAP warm-up protocol affects volume, rating of perceived exertion (RPE), and peak velocity and power with 75%1RM in the barbell parallel back squat (PBS) exercise across 4 sets. …

Patterns Of Participation And Performance In Youth Baseball Players, Amanda Arnold

Theses and Dissertations

Baseball is a popular sport to play in the United States, with approximately 13-17 million athletes participating across all levels of competition. Youth (9-12 years) and adolescent (13-18 years) players comprise the majority of this population playing at the club and high school levels, yet less than 10% of research studies include athletes <18 years old. Despite increased awareness of the risks surrounding sports participation, youth and adolescent baseball players continue to report overuse injuries at alarming rates.

The lack of high-quality research describing athletic performance and injury risk factors, such as sport specialization, in young athlete populations poses a significant knowledge gap in the literature. The current investigation sought to establish the incidence of upper extremity (UE) injuries while examining population-specific risk factors in …
