Efficacy Of Partial Rom Squat In Maximal Strength Training, Caleb Bazyler
Efficacy Of Partial Rom Squat In Maximal Strength Training, Caleb Bazyler
Electronic Theses and Dissertations
Eighteen well trained males (1RM Squat: 150.57 ± 26.79 kg) were assigned to two groups: full ROM training (control) and full ROM with partial ROM training (CP) for the seven-week training intervention. There was a significant time effect (p
Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman
Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman
Electronic Theses and Dissertations
Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality …
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, …
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; …
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 Phosphatidylserine On Reaction Time And Cognitive Function Following An Exercise Stress, Adam John Wells
The Effects Of Phosphatidylserine On Reaction Time And Cognitive Function Following An Exercise Stress, Adam John Wells
Electronic Theses and Dissertations
Phosphatidylserine (PS) is an endogenously occurring phospholipid that has been shown to have cognition and mood enhancing properties in humans, possibly through its role as an enzyme co-factor in cellular signal transduction. Specifically, PS has been identified as activator of classical isoforms of protein kinase C, an enzyme known to be involved in the growth and differentiation of neural cells, and is therefore thought to play a role in the protection of neurons. The purpose of this study was to examine the effects of supplementation with PS and caffeine on measures of cognition, reaction time and mood prior to and …
Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams
Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams
Electronic Theses and Dissertations
Phosphatidic Acid (PA) is a natural phospholipid compound derived from lecithin which is commonly found in egg yolk, grains, fish, soybeans, peanuts and yeast. It has been suggested that PA is involved in several intracellular processes associated with muscle hypertrophy. Specifically, PA has been reported to activate protein synthesis through the mammalian target of rapamycin (mTOR) signaling pathway and thereby may enhance the anabolic effects of resistance training. To our knowledge, no one has examined the effect of PA supplementation in humans while undergoing a progressive resistance training program. To examine the effect of PA supplementation on lean soft tissue …
The Effect Of A Commercially Available Caffeine Based Dietary Supplement On 40-Kilometer Time Trial Performance, Lee A. Weidauer
The Effect Of A Commercially Available Caffeine Based Dietary Supplement On 40-Kilometer Time Trial Performance, Lee A. Weidauer
Electronic Theses and Dissertations
Purpose: To determine wheather ot not the nutritional supplement PreRace containing L-Taurine, Citrulline Malate, Quercetin, DiMethyl Amino Ethanol, Caffeine, Metabromine, Catechin, and Malic acid will improve performance in an indoor 40 Kilometer cycling time trial.
Methods: Seven male cyclists ages 21-58 participated in a placebo-controlled investigation which consisted of two trials in which they consumed either the supplement PreRace or aloe vera juice. In each of the trials the placebo or supplement was mixed with a sports beverage. Subjects performed a 40 kilometer time trial and measurements of oxygen consumption and lactate were taken every 15 minutes as well as …
An Investigation Of The Validity Of Selected Submaximal Field Tests To Estimate Aerobic Capacity In Untrained Females, Barbara A. Moran
An Investigation Of The Validity Of Selected Submaximal Field Tests To Estimate Aerobic Capacity In Untrained Females, Barbara A. Moran
Electronic Theses and Dissertations
The purpose of this investigation was twofolds (1) to determine the validity of selected submaximal field tests used to estimate aerobic capacity, and (2) to determine the association of maximal oxygen consumption with the performance of selected submaximal field test. Eighteen females (X = l.9.4 yrs) volunteered to be Ss. Prior to the first two field tests, anthropometric data of ht and wt were collected and %BF, FW, and FFW were computed from skinfold measurements. The field tests investigated were the 12 min run, the 600 yd run, and the QCST. All measurements were analyzed for reliability and reproducibility by …
