Prolonged Load Carriage Impacts Magnitude And Velocity Of Knee Adduction Biomechanics, Gaervyn John Salverda

Boise State University Theses and Dissertations

Introduction: Adopting knee adduction biomechanics during prolonged load carriage, a common military occupational activity, may increase service members knee osteoarthritis (OA) risk. Although service members reportedly increase knee adduction motions and moments during prolonged load carriage, it is unknown if either body borne load or walk duration increases velocity of knee adduction biomechanics, and subsequent knee OA risk. Varus thrust and alignment are also related to greater knee OA risk, yet it is unknown whether varus thrust and/or alignment are related to magnitude and velocity of knee adduction biomechanics during prolonged load carriage. Purpose: To determine whether body borne load …

In this study, we investigated the effects of football shoes with different collar heights on ankle biomechanics and dynamic postural stability. Fifteen healthy college football players performed anterior and lateral single-leg jump landings when wearing high collar, elastic collar, or low collar football shoes. The kinematics of lower limbs and ground reaction forces were collected by simultaneously using a stereo-photogrammetric system with markers (Vicon) and a force plate (Kistler). During the anterior single-leg jump landing, a high collar shoe resulted in a significantly smaller ankle dorsiflexion range of motion (ROM), compared to both elastic (p = 0.031, dz = …

Analyzing Change-Of-Direction And The Laterally Resisted Split Squat: Incorporating A Lateral Vector Into The Single Leg Squat, Derek Maddy

Boise State University Theses and Dissertations

Improving change of direction (COD) with the use of strength training has led to mixed results. To date, the modified single leg squat (MSLS) and the bilateral squat (BS) have been successfully used to improve COD, with equal improvement. COD is primarily performed at a 45-75° frontal plane angle; however, the MSLS and BS are performed at a 90° frontal plane angle. Based on the force vector theory, it is proposed that a more mechanically similar strength training exercise, the Laterally Resisted Split Squat (LRSS), be used. The purpose of this study is to compare COD with the LRSS, MSLS, …

Increased Sod2 In The Diaphragm Contributes To Exercise-Induced Protection Against Ventilator-Induced Diaphragm Dysfunction, Stephanie E. Hall

Kinesiology Faculty Publications and Presentations

Mechanical ventilation (MV) is a life-saving intervention for many critically ill patients. Unfortunately, prolonged MV results in rapid diaphragmatic atrophy and contractile dysfunction, collectively termed ventilator-induced diaphragm dysfunction (VIDD). Recent evidence reveals that endurance exercise training, performed prior to MV, protects the diaphragm against VIDD. While the mechanism(s) responsible for this exercise-induced protection against VIDD remain unknown, increased diaphragm antioxidant expression may be required. To investigate the role that increased antioxidants play in this protection, we tested the hypothesis that elevated levels of the mitochondrial antioxidant enzyme superoxide dismutase 2 (SOD2) is required to achieve exercise-induced protection against VIDD. Cause …

The Association Between The Coach-Athlete Relationship And Burnout Among High School Coaches, Scott Westfall, Eric M. Martin, Daniel Gould

Kinesiology Faculty Publications and Presentations

Burnout is a term that continues to raise considerable concern among high school coaches and administrators (Raedeke, 1997) and has shown to have negative effects on coaches and athletes alike (Price & Weiss, 2000; Vealey, Armstrong, & Comar, 1998). While burnout has shown to have significant adverse effects, few studies have examined how the coach-athlete relationship may affect a coach s level of perceived burnout. This study sought to understand if the coach-athlete relationship predicted coach burnout. High school coaches (69 males, 62 females) completed the Coach-Athlete Relationship Questionnaire (CART-Q; Jowett & Ntoumanis, 2004), the Coaching Burnout Questionnaire, a modified …

Kinesiology Faculty Publications and Presentations

With provisions in the Every Student Succeeds Act, attention to physical education (PE) programs in school will be crucial for developing well-rounded students. We assessed the availability of resources that have the potential to impact PE (staffing, continuing education, annual PE equipment budgets) in a nationally-representative sample of 640 U.S. public elementary schools. Higher student-to-PE teacher ratios were associated with students not receiving adequate instruction. Equipment budgets were minimal (median = $500) and 30% of schools had no budget at all. Additional financial support from federal and state education agencies would help schools to better meet recommendations for PE.
