The Relationship Between Perfectionism And Self-Determined Motivation In Collegiate Division I Athletes, Christian Sengfelder May 2019

The Relationship Between Perfectionism And Self-Determined Motivation In Collegiate Division I Athletes, Christian Sengfelder

Boise State University Theses and Dissertations

Introduction: An athlete’s performance is dependent on both psychological and physical factors. Perfectionism and motivation are two psychological factors that can influence performance of athletes in a positive or negative manner. The relationship between perfectionism and motivation has been studied previously, but the relationship has not been studied with sport specific measurements and the collegiate athlete population has largely been ignored. Purpose: To investigate the levels of perfectionism and motivation in collegiate Division I student-athletes and determine how the forms of perfectionism (adaptive versus maladaptive) are related to the different levels of motivation (controlled vs autonomous forms) in this ...

Effects Of Attentional Focus On An Underhand Tossing Task Among Young Children, Amanda B. Seneri May 2015

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, 1980, 1984, 1986). The purpose of this study was to examine the effects of attentional focused instruction and feedback on the performance outcome of an underhand tossing task among first graders. It was hypothesized the external focused group would perform with better outcome scores compared to the internal focused group. Three intact classes of first graders were recruited from a local elementary school in the Northwest. Within each class participants were quasi-randomly divided into two treatment groups (either external or internal attentional focus), with an equal representation of gender in each group. Twenty-five participants (M = 6.26 yrs, SD = 0.45) engaged in pretest, acquisition, retention and transfer trial blocks, each completing a total of 80 tosses over a three-week period. Performance outcomes were assessed using a circular target similarly used by Chiviacowsky et al. (2013) and Saemi, Porter, Wulf, Ghotbi-Varzaneh, & Bakhtiari vi (2013). Outcome scores during acquisition were analyzed using a 2 (Group: Int., Ext.) X 6 (Pretest, Acquisition Trial Blocks) ANOVA with repeated measures on the last factor. Outcome scores during acquisition trial block 5, retention, and transfer was analyzed using a 2 (Group: Int., Ext.) X 3 (Acquisition Block 5, Retention, Transfer) ANOVA with repeated measures on the last factor. No significant differences were found between groups during the pretest and acquisition (p = 0.56) or during acquisition trial block 5, retention and transfer (p = 0.71). Although non-significant, the internal focus group performed the task with slightly better performance outcome scores during acquisition, retention and transfer trial blocks. There was a significant difference within groups during acquisition trial block 5, retention and transfer trial blocks (p < 0.005). Both groups exhibited a decrease in scores during the transfer trial block. The results from this study did not support the hypothesis or previous research (Chiviacowsky et al., 2013; Perreault, 2013, Exp. 2; Saemi et al., 2013; Thorn, 2006; Wulf, Chiviacowsky, et al., 2010). However, these results demonstrated similar findings to Emanuel and colleagues (2008) and Perreault (2013, Exp. 1). Future research should continue to focus on this age population to gain a better understanding ...

The Effect Of Attentional Focus Instructions On Golf Swing Performance In Recreational Golfers, Jeffrey D. Eggleston

Boise State University Theses and Dissertations

Previous research has addressed the effectiveness of attentional focus instructions in improving golf performance with a single training session. The purpose of the current study was to investigate the effect of external (EF) attentional focus instructions on recreational golfers’ performance over a distributed training period and extended retention interval. Performance was measured by club head velocity (CHV) and X-factor as both have been correlated with greater performance. The current study extends the work of An, Wulf, and Kim (2013), by increasing the training period and retention interval. It was hypothesized EF group would have greater CHV and X-factor measurements during ...

Strategies To Decrease Movement Variability In The Ankle Joint In Cyclists, Claudia Guadalupe Chavez Nov 2013

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. Participants were provided with internally ...

Kinematics And Muscle Activation Patterns During Simulated Uphill Pedaling On An Indoor Cycle Ergometer, Benjamin Thomas Stein

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 Aug 2011

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 ...


Walk-Run Transition Speed And The Relevance Of Loading, Muscular Fatigue, And Human Kinematics: A Comparison Of Human Gait Patterns, Callie Elizabeth Gunderson May 2011

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 = 9 obese; age M = 26.3 ...

A Case Study On The Use Of Athletic Performance Strategies In An Elite Athlete’S Management Of Pancreatic Cancer, Brooke Elisabeth Harris

Boise State University Theses and Dissertations

In 2007, 11.7 million people in the United States were living with a cancer diagnosis. Specifically, 12 in every 100,000 Americans are diagnosed with pancreatic cancer each year. The five year survival rate of pancreatic cancer in the United States is only 5.6% (National Cancer Institute, 2007). In addition to traditional pharmacological treatments, physical activity has been increasingly used to help individuals successfully cope with cancer. One area that has not been studied extensively is the use of sport psychology techniques to help athletes cope with cancer. It is possible that these techniques, learned by elite athletes ...


Differences In Muscle Activation In The Lower Extremities While Performing Traditional Squats And Non-Traditional Squats, Christopher M. Scotten Aug 2010

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 ...


Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald Aug 2010

Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald

Boise State University Theses and Dissertations

The purpose of this study was to determine if a difference exists in hip power asymmetry between community-dwelling older adult fallers and non-fallers. Hypothesis: fallers would be more asymmetrical than non-fallers. Participants: 21 non-fallers (10 females, 11 males) and 18 fallers (14 females, 4 males) over the age of 65 (76.5 ± 6.9yrs). Method: Isokinetic peak torque during flexion, extension, abduction, and adduction at four velocities was recorded as measures of leg power. Asymmetry equaled the percent of power difference between each leg. Data analysis: Differences in age, physical activity, height, weight, and BMI were assessed using independent t-tests ...

Assessment Of Lactate Response After The Completion Of Three Different Volume Patterns Of Power Clean, Anand Date Dec 2009

Assessment Of Lactate Response After The Completion Of Three Different Volume Patterns Of Power Clean, Anand Date

Boise State University Theses and Dissertations

The ability of continuous lactate clearance and the inflection points of the lactate curve are two important determinants of performance of competitive field athletes. Current training practices for improving lactate tolerance such as high intensity aerobic activities and the combination of aerobic and resistance training seem to have undesired physiological adaptations (e.g. muscle loss, change in fiber types). The Role of Explosive power movements in lactate accumulation has not been studied properly. Hence, the purpose of this study was to assess lactate response after the completion of three different volume patterns of the power clean movement. Ten male recreational ...

Differences In Upper Body Posture And Postural Muscle Activation In Females With Larger Breast Sizes, Mindy Bennett May 2009

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 ...
