The Effects Of A 10-Week Judo Program On Cortisol And Stress In Children With Autism Spectrum Disorder, Justine Renziehausen
The Effects Of A 10-Week Judo Program On Cortisol And Stress In Children With Autism Spectrum Disorder, Justine Renziehausen
Electronic Theses and Dissertations
Children diagnosed with Autism Spectrum Disorder (ASD) often have increased levels of stress, leading to dysregulated production of cortisol. Elevated levels of cortisol have numerous known adverse health consequences, and therefore, interventions should be established to help attenuate cortisol production. As judo combines physical activity and mindfulness practice, it may aid in stress reduction and decreased levels of cortisol. Purpose: To examine the effects of a 10-week judo program on stress reactions and salivary cortisol levels in youth with ASD. Methods: 20 children with ASD participated in the 10-week judo program. Changes in acute (before and after one judo session) …
The Effects Of Dynamic Versus Isometric Postactivation Potentiation On Collegiate Female Rowers, Idan Harat
The Effects Of Dynamic Versus Isometric Postactivation Potentiation On Collegiate Female Rowers, Idan Harat
Electronic Theses and Dissertations
Post-activation potentiation (PAP) has been shown to improve acute power-based performance, and the potential to enhance rowing performance. To examine PAP effects with rowing performance, 40 collegiate female rowers performed isometric potentiating (ISO), dynamic potentiating (DYN) and typical control (CON) warm-up protocols, after which they completed a three-minute all-out test (3MT) to evaluate their total distance, peak power, mean power, critical power, anaerobic working capacity (W') and stroke rate. Fifteen-second splits for distance and mean power were also analyzed. The PAP protocols were performed on a rowing ergometer, in a movement pattern that simulated rowing. ISO consisted of 5 × …
The Impact Of Judo On Aggressive Behaviors In Youth With Autism Spectrum Disorder, Paola Rivera
The Impact Of Judo On Aggressive Behaviors In Youth With Autism Spectrum Disorder, Paola Rivera
Electronic Theses and Dissertations
The aim of this study was to examine the effects of an 8-week judo program on lifestyle habits and behavior in children with Autism Spectrum Disorder (ASD). METHODS: Participants included 25 children (ages 8-17), with a formal diagnosis of ASD. The sample participated in an 8-week judo program (45 minutes, 1x week), with measures taken at baseline and at the end of the 8-weeks. In order to assess activity levels and sleep quality, participants were instructed to wear Actigraph GT9X Accelerometers for 7 days and nights. In order to assess behavioral changes, parents were given the ABC survey to fill …
Ultrasound Measured Flexor Muscle Thickness In The Forearms Of Rock Climbers, Michael Marsala
Ultrasound Measured Flexor Muscle Thickness In The Forearms Of Rock Climbers, Michael Marsala
Electronic Theses and Dissertations
PURPOSE: To examine differences in the forearms of rock climbers using ultrasound to measure the muscle thickness of the finger flexors. METHODS: A total of 33 participants were recruited, 22 climbers (22.23 years; 68% male) and 11 controls (21.8; 55% male). Climbers provided self-reported ratings of their climbing ability, skill level, and preferred mode of climbing (e.g. sport climbing vs. bouldering). Anthropometric measures, including body fat percentage, were measured in all participants. Ultrasound measurements were taken with the participant lying on their back on a padded table with their dominant hand supinated. Muscle thickness measurements were taken at the forearm …
Changes In Running And Multiple Object Tracking Performance During A 90-Minute Intermittent Soccer Performance Test (Ispt): A Pilot Study, Ryan Girts
Electronic Theses and Dissertations
Multiple object tracking (MOT) is a cognitive process that involves the active processing of dynamic visual information. In athletes, MOT speed is critical for maintaining spatial awareness of teammates, opponents, and the ball while moving at high velocities during a match. Understanding how MOT speed changes throughout the course of a competitive game may enhance strategies for maintaining optimal player performance. The objective of this study was to examine changes in MOT speed and running performance during a 90-minute intermittent soccer performance test (iSPT). A secondary purpose was to examine the relationship between aerobic capacity and changes in MOT speed. …
Minimal Effects Of Moderate Normobaric Hypoxia On The Upper-Body Work-Time Relationship In Recreationally-Active Women, Tristan Starling-Smith
Minimal Effects Of Moderate Normobaric Hypoxia On The Upper-Body Work-Time Relationship In Recreationally-Active Women, Tristan Starling-Smith
Electronic Theses and Dissertations
PURPOSE: To evaluate the effects of moderate normobaric hypoxia on the parameters of the work-time relationship during upper body exercise in women. METHODS: Thirteen recreationally active women (age: 22.7 ± 2.6 y; height: 167 ± 8.6 cm; weight: 66.4 ± 9.7 kg; body fat: 27.6 ± 5% body fat) completed a graded exercise test in both normobaric hypoxia (H; FiO2=~14%) and normoxia (N; FiO2=~20%) to exhaustion on an arm ergometer to determine V̇ O2peak and peak power output (PPO). Each participant completed four constant work-rate arm-cranking tests at 90-120% PPO in both environmental conditions. Linear regression was used to estimate …
Acute Effects Of Placebo And Open-Label Placebo Treatments On Muscle Strength, Voluntary Activation, And Neuromuscular Fatigue., Alina Swafford
Acute Effects Of Placebo And Open-Label Placebo Treatments On Muscle Strength, Voluntary Activation, And Neuromuscular Fatigue., Alina Swafford
Electronic Theses and Dissertations
Placebo treatments have long been used to study the psychological effects of expectancy and conditioning on an inert intervention. Interestingly, open-label placebo treatments (i.e., directly telling subjects they are receiving an inactive intervention) have recently shown promise in minimizing pain in clinical patient populations. We utilized a repeated measures design to examine the acute effects of placebo, open-label placebo, and control treatments on muscle strength and voluntary activation (Experiment #1), as well as neuromuscular fatigue (Experiment #2). Twenty-one untrained males (n=11) and females (n=10) visited the laboratory on three occasions to receive each treatment in a randomized, counter-balanced manner. All …
