Effects Of Flywheel Resistance Training On Muscle Function And Sport-Specific Performance In Collegiate Club Water Polo Players, Jennifer Xu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Flywheel training has been shown to be beneficial for improving a multitude of muscle function and performance parameters, but its short-term training effects on athletic performance have yet to be established. PURPOSE: To investigate the effects of four weeks of flywheel squat training on lower body muscle function adaptations and sport-specific performance in collegiate club water polo players. METHODS: Thirteen men and women who participated in collegiate club water polo performed flywheel squat training twice a week for four weeks. Isokinetic knee extension peak power (PP) and peak torque (PT), flywheel squat peak power (FPP) and mean power (FMP), countermovement …

Interdevice Reliability Of A-Mode Ultrasound To Measure Body Composition, Megan Bigler

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A-mode ultrasound is a noninvasive and rapid method for measuring subcutaneous fat thickness and estimating body fat percentage (%BF). The validity and reliability of the BodyMetrix BX2000 A-mode ultrasound has been reported; however, the purpose of this study was to compare results from two machines to determine interdevice reliability. Ultrasound measures were repeated with two BX2000 machines at 10 body sites (chest, biceps, triceps, scapula, lower back, hip, waist, thigh, calf, axilla) on 42 males of varying age and leanness (age: 28.6 ± 11.9 y, BMI: 25.4 ± 4.6 kg/m²). The intraclass correlation coefficients ranged from 0.939 to …

Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Eccentric resistance training has been shown to be beneficial for improving multiple performance and health metrics. However, recommendations on eccentric training frequency have not been established. PURPOSE: To investigate the effects of volume-matched resistance training frequency comparing one versus three training days per week of isokinetic multiple-joint eccentric training on strength and lower body function adaptations during a 4-week training period. METHODS: Thirty recreationally-trained men and women were randomly assigned to either a high frequency (HF), three times per week, or low frequency (LF), once per week, training group for four weeks. A motor-driven isokinetic eccentric dynamometer was used for …

Reliability Of The Wingate Anaerobic Test With Ice Hockey Players On The Velotron Cycle Ergometer, Ryan F. Bringhurst, Dale R. Wagner, Sarah Schwartz

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: This study evaluated the test-retest reliability of the Wingate Anaerobic Test (WAnT) performed on a Velotron electromagnetically-braked cycle ergometer (EE) for power-trained athletes and assessed whether a familiarization trial was necessary to achieve high test-retest reliability. Methods: Twenty-one male ice hockey players (age 23.5 ± 4.7 yrs, mass 86.3 ± 16.6 kg, height 180.9 ± 7.4 cm) from a collegiate club team (Club = 10) and a recreational league (Rec = 11) performed three, 30-sec WAnTs within 2 weeks, and with at least 24 hours between visits. Mean power, anaerobic capacity, peak power, anaerobic power, maximum RPM, …

Comparison Of Take Off Kinematics During Loaded Countermovement Jumps In Division One Female Gymnasts And Soccer Athletes, Ryan Moreau

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: The purpose of this study was to compare takeoff kinematics of incrementally loaded countermovement jumps (CMJ) in water and land in female gymnasts and soccer athletes.

Methods: 24 Division I student athletes (12 gymnastics, 12 soccer) volunteered for this study. Subjects performed CMJ on land and water at a level of the xiphoid process without an arm swing. CMJs with loads of body weight (BW), 10% BW, 20% BW, and 30% BW were performed three times per trial at each load. 15 kinematic variables related to the lower extremity were examined.

Results: For environment, significant (p less than …

Effect Of Step Rate On Foot Strike Pattern And Running Economy In Novice Runners, Janae Lynn Richardson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose—The objective was to examine if step rates ±5% or ±10% of a novice runner's preferred step rate (SR) is sufficient enough to shift a novice runner’s foot strike pattern (FSP) (rear-foot, mid-foot, forefoot) and whether these SR changes produce changes in the rate of submaximal oxygen consumption (VO2). Methods—Foot strike angle (FSA) was recorded using sagittal plane video images and VO2 was measured for novice runners while running on a treadmill at a constant speed during increased and decreased (±5% and ±10%) SR conditions. Foot strike angle was used to predict strike index (SI) (predicted strike index = [FSA …

The Effect Of Implementing A Weight Loss Program On Participant Attendance, Club Usage, And Gym Membership Attrition, Stephanie Bonkemeyer Haymond

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this research study was to evaluate the effect of a weight loss program on individual participant attendance, total club usage and membership attrition. This retrospective study involved a fitness gym located in Utah County, Utah with a total membership of 1,100. The number of clients participating in the weight loss program between December 2011 and May 2012 was 36 (32 females and 4 males). A total of 11 clients were analyzed for the individual attendance data as this analysis was limited to only those clients who were gym members one year prior to the implementation of the …
