Examination Of The Relationship Between Sport Concussion And Long Term Neurodegenerative And Psychological Disorders: A Literature Review, Vivian Rivera
HIM 1990-2015
Background: According to the Center for Disease Control and Prevention, approximately 1.6 to 3.8 million Americans suffer a sports related concussion each year. Concussion is defined as a transient alteration of the brain structure caused by a direct or indirect force. During the last decade, a vast amount of clinical research on the long term effects of repetitive head trauma has occurred, especially on the subject of chronic traumatic encephalopathy (CTE), depression and dementia. Objective: The purpose of this literature review is to examine the literature pertaining to multiple concussion and the long-term effects of multiple concussion such as neurodegenerative …
Do Changes In Muscle Architecture Effect Post- Activation Potentiation, Danielle Reardon
Do Changes In Muscle Architecture Effect Post- Activation Potentiation, Danielle Reardon
Electronic Theses and Dissertations
Purpose: To examine the effect of three muscle potentiation protocols on changes in muscle architecture and the subsequent effect on jump power performance. Methods: Maximal (1RM) squat strength (Mean SD=178.3 ± 36.6kg), vertical jump power, and muscle architecture were obtained in 12 resistance trained men (25.2±3.6y; 90.67±12.7kg). Participants randomly completed three squatting protocols at 75% (3 x 10 reps), 90% (3 x 3 reps) or 100% (1 x 1) of their 1RM, or no workout (CON), with each protocol being separated by one week. During each testing session ultrasound and vertical jump testing were assessed at baseline (BL), 8min post …
The Effects Of 6-Weeks Of Resistance Training On The Neuromuscular Fatigue Threshold In Older Adults, Nadia Emerson
The Effects Of 6-Weeks Of Resistance Training On The Neuromuscular Fatigue Threshold In Older Adults, Nadia Emerson
Electronic Theses and Dissertations
Age-related deficits in muscle mass, strength, and function place an increased burden of work on existing skeletal muscle and may lead to early onset of neuromuscular fatigue (NMF) during activities of daily living. Resistance exercise (RE) is the proven method for improving neuromuscular function in healthy older adults. PURPOSE: To investigate the effects of 6 weeks of RE on the NMF threshold as well as strength and functional performance in older adults. METHODS: Twenty-four older adults were randomly assigned to 6 weeks of RE (EXE; n = 12; age 72 ± 6.3 y; BMI 28.4 kg/m2 ) or control (CONT; …
Physiological Muscle Qualitative Changes In Response To Resistance Training In Older Adults, Tyler Scanlon
Physiological Muscle Qualitative Changes In Response To Resistance Training In Older Adults, Tyler Scanlon
Electronic Theses and Dissertations
Muscle function is determined by structure and morphology at the architectural level. In response to resistance training, older adults have demonstrated that the neuromuscular system has a substantial adaptability, which may compensate for muscle size and quality and lead to improved functional capacities and higher quality of life. PURPOSE: The purpose of this study was to examine the effect of six weeks of progressive resistance exercise on muscle morphology and architecture in healthy older adults. METHODS: Twenty- five healthy men and women were randomly assigned to either six weeks of progressive resistance training (RT) (n=13; age = 71.08 ± 6.75, …
