The Effects Of Prophylactic Ankle Bracing On Knee And Hip Mechanics In Basketball Players During Jump Landing, Riann Thayer
The Effects Of Prophylactic Ankle Bracing On Knee And Hip Mechanics In Basketball Players During Jump Landing, Riann Thayer
Cal Poly Humboldt theses and projects
Background: Many athletes of various sports have been required to wear ankle braces for prophylactic uses. Ankle braces have been shown to decrease range of motion in all directions, which means the main force absorption mechanism of the ankle may be inhibited. This decrease in force absorption at the ankle may increase the mechanical demands at the more proximal knee and hip joints. In this study, the change in knee, hip and lower back mechanics will be investigated to gain understanding as to whether bracing the ankle could create a higher injury potential. Methods: In this study, 12 intercollegiate basketball …
Effects Of A Peer-Assisted Physical Activity Program On Depression And Anxiety In College Students, Crystal Stroud
Effects Of A Peer-Assisted Physical Activity Program On Depression And Anxiety In College Students, Crystal Stroud
Cal Poly Humboldt theses and projects
The purpose of this qualitative study was to examine the effects of a peer-assisted, self-selected physical activity program on depression and anxiety in students at a four-year university, and to explore the various possible mechanisms by which depression and anxiety were affected. These mechanisms included physical activity, self-efficacy, relatedness, competence, and autonomy. A secondary purpose was to examine the benefits of participation for the physical activity buddies who provided the peer-support. In-depth interviews were conducted with three program participants with depression and/or anxiety, six physical activity buddies who supported the participants, and three referring professional healthcare providers. A qualitative data …
The Effect Of Stride Frequencies On Running Performance At The Velocity Of Vo2max, Boram Lim
The Effect Of Stride Frequencies On Running Performance At The Velocity Of Vo2max, Boram Lim
Cal Poly Humboldt theses and projects
Running economy(RE) is considered to be a critical factor to improve running performance. Stride frequency(SF) is an important variable for determining RE. The importance of SF has gained more attention in recent years, especially for recreational runners. However, no previous research has investigated the interaction between running performance and SF at the velocity of VO2max. PURPOSE: To investigate the effect of five different SF variations on running performance until volitional fatigue at the velocity of VO2max. METHODS: Fourteen male recreational runners (Age = 25.8 ± 4.96 years, Height = 171 ± 6.2cm, Body Mass = 71.9 …
The Effect Of Postural Alterations On Metabolic Cost In Running On Incline Slopes, Nikaela K. Hemminger
The Effect Of Postural Alterations On Metabolic Cost In Running On Incline Slopes, Nikaela K. Hemminger
Cal Poly Humboldt theses and projects
In spite of an intuitive relationship between running technique and performance, the influence of specific techniques on metabolic cost remains unclear. While recent studies suggest that postural lean affects metabolic cost during level ground running, little information exists regarding the influence of postural lean on the metabolic cost of running on an incline slope. Purpose: This study sought to investigate the effect of postural lean on metabolic cost, kinematics, and muscle activation of running across a range of incline slopes. Methods: Sixteen healthy adult runners (21±2 years, 8M/8F) of different competitive standards participated in twelve running trials on a motorized …
Hobby Preferences And Physical Activity Participation Among Children With And Without Autism Spectrum Disorder, Scott M. Russell
Hobby Preferences And Physical Activity Participation Among Children With And Without Autism Spectrum Disorder, Scott M. Russell
Cal Poly Humboldt theses and projects
BACKGROUND: Children diagnosed with Autism Spectrum Disorder (ASD) exhibit low physical activity levels and are at an increased risk for health problems related to sedentary behaviors. Hobby preferences have been shown to influence physical activity participation. PURPOSE: The purpose of this study is to examine the hobby preferences of children with ASD and determine if there are differences depending on the children’s physical activity level and the nature of their preferred activities. A secondary purpose is to describe the hobby preferences of children with ASD. METHODS: Participants include 98 nine-year-old children (with and without ASD) from the National Growing up …
Changing Parental Perceptions Of Children With Disabilities Physical Capability In Physical Activity Through A Family Fitness Program, Katelyn R. A. Knupper
Changing Parental Perceptions Of Children With Disabilities Physical Capability In Physical Activity Through A Family Fitness Program, Katelyn R. A. Knupper
Cal Poly Humboldt theses and projects
Children with disabilities are not participating in enough physical activity to meet the recommendations for health benefits. Parental perceptions of their child’s physical competence has a role in influencing physical activity levels. Parental perceptions can be improved through observations of their children in successful physical situations. Therefore, the purpose of this study was to analyze change in parental perceptions of their child’s physical competence after participating in a family-centered physical activity program. Five parents with a child aged six to 21 years with a disability participated in this study. Parental perceptions were assessed with the Perceived Competence Scale for Children, …
