The Training Of A Para Powerlifter: A Case Study Of Adaptive Monitoring, Training And Overcoming, Derek Wilcox
The Training Of A Para Powerlifter: A Case Study Of Adaptive Monitoring, Training And Overcoming, Derek Wilcox
Electronic Theses and Dissertations
Paralympic athletes (PA) appear to be more prone to chronic overuse injuries from daily wheelchair or crutch use. Over half of these injuries are shoulder related which can deleteriously impact quality of life. Adaptive powerlifters (AP) are a subdivision of Paralympic athletes and are at a higher risk for catastrophic injuries as compared to their counterparts, due to the compound of fatigue and lifting of maximal weights. For this reason, it is vital to have well-designed training plans for these athletes in order to preserve quality of life and maximize performance in competition. Unfortunately, there is a lack of literature …

Subjects underwent blood glucose testing, completed an Abbreviated Profile of Mood States Questionnaire, and Automated Operation Span (OSPAN) and Digit Span tests to measure memory and attention. On two separate days subjects consumed candy or walked on a treadmill for 10 minutes, then measurements were repeated at 30-min, 60-min, and 120-min post. Two-way ANOVA over time …
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) …

Post-activation potentiation (PAP) is a stimulus used to enhance performance by performing specific interventions prior to subsequent explosive movements. The purpose of this study was to determine the effect of different PAP methods on power and sprint acceleration in resistance trained, college-aged men and women. A total of 13 subjects participated in the study. After determining back squat 1 repetition max, subjects returned for testing on separate days to complete one of four interventions (dynamic resistance, weighted plyometric, isometric, or control) in a randomized order. A standardized warmup was given, followed by a baseline countermovement jump (CMJ) and 20-meter sprint. …
Using Maximum Power As A Variable For 1rm Prediction In The Squat And Bench Press, Sean O'Connor
Using Maximum Power As A Variable For 1rm Prediction In The Squat And Bench Press, Sean O'Connor
Electronic Theses and Dissertations
Many Strength and Conditioning (S&C) coaches utilize a one-rep max (1RM) exercise test to gauge the maximal strength of athletes, and then prescribe resistance training programs based on a relative percentage of 1RM to obtain strength or power adaptations. However, many S&C coaches have raised questions regarding the safety and necessity of a 1RM test. Attempts to mitigate the weaknesses of 1RM testing have led to other methods of testing including repetition max testing (3RM, 5RM, 10RM, etc.) as well as load/velocity profiling. The main purpose of this study is to determine if 1RM can be accurately estimated from maximal …

Resistance training can be periodized numerous different ways, but the most popular training methods are traditional periodization, undulating periodization, and plyometric training. This systematic review and meta-analysis examined studies that compared traditional periodization, undulating periodization, …
Player-Coach Perceptions Of Internal Load, Exertion, And Recovery In Collegiate Male Soccer Players, Michelle L. Eisenman
Player-Coach Perceptions Of Internal Load, Exertion, And Recovery In Collegiate Male Soccer Players, Michelle L. Eisenman
Electronic Theses and Dissertations
Periodization of athlete training load to improve performance and maximize recovery, while reducing injuries and overtraining, is essential in team sports. Understanding internal load responses and monitoring athlete exertion and recovery can help coaches during a competitive season. Recovery Status (PRS) and Rating of Perceived Exertion (RPE) are two subjective scales used to help quantify training load and recovery. These scales are more useful if there is an agreement between coaches (C) and players (P) assessment of intensity and recovery. PURPOSE: To assess subjective measures (PRS and RPE scores) from P and C during a 13-week competitive soccer season. Furthermore, …
