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 ...

Increasing lower limb flexion may reduce risk of musculoskeletal injury for military personnel during landing. This study compared lower limb biomechanics between sexes and limbs when using normal and greater lower limb flexion to land with body borne load. Thirty-three participants (21 male, 12 female, age: 21.6±2.5 years, height: 1.7±0.1 m, weight: 74.5±9.0 kg) performed normal and flexed lower limb landings with four body borne loads: 20, 25, 30 and 35 kg. Hip and knee biomechanics, peak vertical ground reaction force (GRF), and the magnitude and direction of the GRF vector ...


Measurement Invariance And Latent Mean Differences Of The Chinese Version Physical Activity Self-Efficacy Scale Across Gender And Education Levels, Han Chen, Jun Dai, Yong Gao Jan 2019

Background: Self-efficacy has been identified as an important determinant of youth’s behavior change including physical activity (PA) participation. However, the dimensionality check of a PA self-efficacy scale has rarely been conducted in China. The current study aims to examine (1) the unidimensionality of a shortened Chinese version of PA self-efficacy scale (S-PASESC); (2) the measurement invariance of S-PASESC across gender and levels of education; (3) the latent factor mean difference between gender and levels of education; (4) the direct effects of self-efficacy on PA by different gender and education levels; and (5) the comparisons of the direct effects of ...


Increased Sod2 In The Diaphragm Contributes To Exercise-Induced Protection Against Ventilator-Induced Diaphragm Dysfunction, Stephanie E. Hall Jan 2019

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

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 ...
