Simplifying External Load Data In Ncaa Division-I Men's Basketball Competitions: A Principal Component Analysis, Jason D. Stone, Justin J. Merrigan, Jad Ramadan, Robert Shaun Brown, Gerald T. Cheng, William Guy Hornsby, Holden Smith, Scott M. Galster, Joshua A. Hagen

Faculty & Staff Scholarship

The primary purpose was to simplify external load data obtained during Division-I (DI) basketball competitions via principal component analysis (PCA). A secondary purpose was to determine if the PCA results were sensitive to load demands of different positional groups (POS). Data comprised 229 observations obtained from 10 men's basketball athletes participating in NCAA DI competitions. Each athlete donned an inertial measurement unit that was affixed to the same location on their shorts prior to competition. The PCA revealed two factors that possessed eigenvalues >1.0 and explained 81.42% of the total variance. The first factor comprised total decelerations (totDEC, 0.94), average …

Beyond Weight Loss: A Qualitative Exploration Of Participant Expectations And Strategies For Measuring Progress During A Weight Management Program, John Spencer Ingels, Adam Hansell, Sam Zizzi

Faculty & Staff Scholarship

Objectives:

Previous research with participants in weight management has primarily focused on participant weight-loss expectations. The purpose of this study was to explore participant expectations and strategies for measuring progress during a community-based weight management program.

Methods:

Semi-structured interviews were completed with 22 participants with overweight or obesity, who were currently enrolled in a 2-year weight management program in order to understand their expectations and strategies for measuring their progress.

Results:

Aside from weight loss, participants’ expectations included improved health, fitness, and mood, gaining support, and developing new habits. Participants discussed measuring their success by focusing on weight loss and …

Resistance Training Volume Load With And Without Exercise Displacement, William Guy Hornsby, Jeremy A. Gentles, Paul Comfort, Timothy J. Suchomel

Faculty & Staff Scholarship

Monitoring the resistance training volume load (VL) (sets × reps × load) is essential to managing resistance training and the recovery–adaptation process. Subjects: Eight trained weightlifters, seven of which were at national level, participated in the study. Methods: VL was measured both with (VLwD) and without (VL) the inclusion of barbell displacement, across twenty weeks of training, in order to allow for comparisons to be made of these VL calculating methods. This consisted of recording the load, repetition count, and barbell displacement for every set executed. Comparisons were made between VL and VLwD for individual blocks of training, select training …

Analytical Cpg Model Driven By Limb Velocity Input Generates Accurate Temporal Locomotor Dynamics, Sergiy Yakovenko, Anton Sobinov, Valeriya Gritsenko

Faculty & Staff Scholarship

The ability of vertebrates to generate rhythm within their spinal neural networks is essential for walking, running, and other rhythmic behaviors. The central pattern generator (CPG) network responsible for these behaviors is well-characterized with experimental and theoretical studies, and it can be formulated as a nonlinear dynam- ical system. The underlying mechanism responsible for locomotor behavior can be expressed as the process of leaky integration with resetting states generating appropriate phases for changing body velocity. The low-dimensional input to the CPG model generates the bilateral pattern of swing and stance modulation for each limb and is consistent with the desired …

Respiratory Muscle Training Positively Affects Vasomotor Response In Young Healthy Women, Angela Valentina Bisconti, Michela Devoto, Massimo Venturelli, Randall Bryner, Mark Olfert, Paul D. Chantler, F. Esposito

Faculty & Staff Scholarship

Vasomotor response is related to the capacity of the vessel to maintain vascular tone within a narrow range. Two main control mechanisms are involved: the autonomic control of the sympathetic neural drive (global control) and the endothelial smooth cells capacity to respond to mechanical stress by releasing vasoactive factors (peripheral control). The aim of this study was to evaluate the effects of respiratory muscle training (RMT) on vasomotor response, assessed by flow-mediated dilation (FMD) and heart rate variability, in young healthy females. The hypothesis was that RMT could enhance the balance between sympa- thetic and parasympathetic neural drive and reduce …

Effects Of Mantra Meditation Versus Music Listening On Knee Pain, Function, And Related Outcomes In Older Adults With Knee Osteoarthritis: An Exploratory Randomized Clinical Trial (Rct), Kim Innes, Terry Kit Selfe, Sahiti Kandati, Sijin Wen, Zenzi Huysmans

Faculty & Staff Scholarship

Objective. Disease-modifying treatments for OA remain elusive, and commonly used medications can have serious side effects. Although meditation and music listening (ML) have been shown to improve outcomes in certain chronic pain populations, research in OA is sparse. In this pilot RCT, we explore the effects of two mind-body practices, mantra meditation (MM) and ML, on knee pain, function, and related outcomes in adults with knee OA. Methods. Twenty-two older ambulatory adults diagnosed with knee OA were randomized to a MM (N=11) or ML program (N=11) and asked to practice 15-20 minutes, twice daily for 8 weeks. Core outcomes included …

A Case Study Of International Students’ Social Adjustment, Friendship Development, And Physical Activity, Shaung Li, Sam Zizzi

Faculty & Staff Scholarship

Previous literature has focused on international student’s social transition and monocultural and bicultural ties. Little research has explored international students’ multicultural friendship development and the role that physical activity plays in their social interaction. The current case study explored a group of international students’ friendship development and the social aspect of physical activity. Data from individual interviews (pre and post), and 5 months of participant observations was used to describe two female international students’ experiences. Results suggested international students faced both language and cultural barriers in their social interactions with American students. Engagement in physical activities served as the context …

Resting Hormone Alterations And Injuries: Block Vs. Dup Weight-Training Among D-1 Track And Field Athletes, Keith B. Painter, G Gregory Haff, N Travis Triplett, Chales Stuart, Guy Hornsby, Mike W. Ramsey, Caleb D. Bazyler, Michael H. Stone

Faculty & Staff Scholarship

Daily undulating periodization (DUP), using daily alterations in repetitions, has been advocated as a superior method of resistance training, while traditional forms of programming for periodization (Block) have been questioned. Nineteen Division I track and field athletes were assigned to either a 10-week Block or DUP training group. Year and event were controlled. Over the course of the study, there were four testing sessions, which were used to evaluate a variety of strength characteristics, including maximum isometric strength, rate of force development, and one repetition maximum (1RM). Although, performance trends favored the Block group for strength and rate of force …

Enhancing Collegiate Women’S Soccer Psychosocial And Performance Outcomes By Promoting Intrinsic Sources Of Sport Enjoyment, Scott Barnicle, Damon Burton

Faculty & Staff Scholarship

This study examined the effectiveness of an applied mental skills training (MST) intervention utilizing mental skills to enhance intrinsic sources of enjoyment (ISOEs) as a means of promoting self-confidence, motivational style, and athletic performance, while also decreasing trait anxiety. The interven-tion project was designed to increase intrinsic SOE using a systematic and individualized mental training protocol, and then examine its relationships to mental skills and soccer perfor-mance. A Division 1 collegiate women’s soccer team was ran-domly assigned to treatment (n = 8) and control (n = 11) groups, equally distributed by academic year, position, and pre-season coach-evaluated starters and non-starts. …
