Effects Of Attentional Focus On An Underhand Tossing Task Among Young Children, Amanda B. Seneri

Boise State University Theses and Dissertations

Research has shown that externally focused instruction and feedback has positive effects on skill acquisition and performance outcomes among adults (Wulf, 2007, 2013). However, in children, there are mixed findings as to whether an external or internal focus of attention is most effective (Chiviacowsky, Wulf, & Ávila, 2013; Emanuel, Jarus, & Bart, 2008; Perreault, 2013; Thorn, 2006; Wulf, Chiviacowsky, Schiller, & Ávila, 2010). Currently, there is a gap in the attentional focus literature and a need to research young children, under the age of eight, whose cognitive development is not as matured as older children or adults (Gallagher & Thomas, …

Physiologic Responses Of Firefighting Training Officers In The Structured Live-Fire Firefighting Training, Takahisa Koide

Learning To Play: A “Hedgehog Concept” For Physical Education, Tyler Johnson

Kinesiology Faculty Publications and Presentations

What is physical education and why does it exist? Despite its relatively long and storied history, consensus about physical education’s existence remains minimal. According to Jim Collins, author of the best-selling book Good to Great, organizations or groups of professionals should determine a “hedgehog concept” or a primary reason for their existence. This article explores three questions developed by Collins to help organizations identify a hedgehog concept: (a) what are we deeply passionate about? (b) what can we be the best in the world at? and/or what can we not be the best in the world at? and (c) what …

Strategies To Decrease Movement Variability In The Ankle Joint In Cyclists, Claudia Guadalupe Chavez

Boise State University Theses and Dissertations

Coordination variability is thought to be indicative of a cyclist’s skill level as novices have higher levels of variability than experts (Sides & Wilson, 2012). It was hypothesized that the externally focused instructions with visual feedback group would decrease coordination variability in the ankle joint to a greater extent than those in the internally focused instructions with visual feedback group. Six cyclists (30-40 years) completed a four day acquisition period and a retention test. During this time participants cycled for 10-15 minutes at a power output equal to 2.0-2.5W/kg of body mass.

Boise State University Theses and Dissertations

INTRODUCTION: An indoor cycle ergometer allows for competitive and recreational mountain bike cyclists to simulate uphill conditions with precisely controlled and monitored pedaling. While simulating an uphill condition indoors, with or without a climbing block, the cyclist body may not be in the same position as while pedaling outdoors. This possible difference in body position may have training implications. PURPOSE: The purpose of this study was to determine if there are differences in kinematics and/or muscle activation patterns while pedaling on a level surface compared to an inclined surface while pedaling on a mountain bike on an indoor cycle …

Differences In The Mechanics Between The Dominant And Non-Dominant Plant Limb During Instep Soccer Kicking, Cassidy M. Berlin

Boise State University Theses and Dissertations

INTRODUCTION: Over the past 15 years, participation in women’s soccer has increased drastically and with that comes increased exposure to injury. When athletes perform deceleration tasks, such as planting the limb during a kick, there is an increased risk of anterior cruciate ligament (ACL) injury. Low knee flexion angles at contact, high posterior ground reaction force (GRF), increased lateral trunk lean, high knee abduction angle, and high knee external rotation of the knee have all been identified as potential mechanisms of ACL injury during deceleration tasks. At higher levels of competition, a soccer player becomes more valuable if they are …

Walk-Run Transition Speed And The Relevance Of Loading, Muscular Fatigue, And Human Kinematics: A Comparison Of Human Gait Patterns, Callie Elizabeth Gunderson

Boise State University Theses and Dissertations

INTRODUCTION: The walk-to-run transition (WRT) typically occurs at a preferred transition speed (PTS) of 1.9-2.1ms^-1. Previous research has focused on potential triggers for this transition such as leg length, muscular fatigue, loading rates (LR), and vertical ground reaction forces (VGRFs). Rather than focus on mechanisms responsible for the transition, the purpose of the current study was to determine if basic anthropometrics or gait characteristics are predictive of the WRT. METHODS: Thirty participants were recruited for the current study (n = 13 male, 17 female; n = 11 normal weight, n = 10 overweight, n = …

Differences In Muscle Activation In The Lower Extremities While Performing Traditional Squats And Non-Traditional Squats, Christopher M. Scotten

Boise State University Theses and Dissertations

Purpose: To determine if muscle activation in the lower back and lower extremities differ when performing traditional squats compared to non-traditional (forward center of pressure on foot) squats. The erector spinae, hamstrings, quadriceps, adductor longus, gastrocnemius, and gluteus maximus muscles were monitored for differences in this study. There are several variations of the back squat and each variation may possibly target muscles differently. Determining if non-traditional squats leads to larger erector spinae muscle activation, which in turn may lead to more lower back fatigue and possible lower back injury is a major aim of this study. Participants: Thirteen healthy males …

Differences In Upper Body Posture And Postural Muscle Activation In Females With Larger Breast Sizes, Mindy Bennett

Boise State University Theses and Dissertations

Breast hypertrophy is a common medical condition whose morbidity has increased over recent decades. Symptoms of breast hypertrophy often include musculoskeletal pain in the neck, back and shoulders, and numerous psychosocial health burdens. To date, reduction mammaplasty (RM) is the only treatment shown to significantly reduce the severity of the symptoms associated with breast hypertrophy. However, due to a lack of scientific evidence in the medical literature justifying the medical necessity of RM, insurance companies often deny requests for coverage of this procedure. Therefore, the purpose of this study is to investigate biomechanical differences in the upper body of women …
