The Effects Of Moderate Intensity Strength Training Coupled With Blood Flow Restriction: A 12 Week Intervention, Kelly Barrett 2017 The University of Western Ontario

The Effects Of Moderate Intensity Strength Training Coupled With Blood Flow Restriction: A 12 Week Intervention, Kelly Barrett

Electronic Thesis and Dissertation Repository

Blood flow restriction training (BFRT) has been suggested to increase muscle size and strength in trained and untrained individuals when using light load intensities (30 percent 1-RM). However, there is little data to support its use when working with moderate load intensities, specifically, above 50 percent of an individual’s 1-RM. The purpose of this study was to evaluate the effects of moderate load intensity BFRT on muscle size and strength of the biceps brachii after a 12 week strength training intervention. Nine, previously strength trained, participants performed an elbow flexion exercise at 70 percent of their individualized 1-RM, twice ...

OBJECTIVE: Protein-pacing (P; 5-6meals/day @ 2.0g/kgBW/day) and multi-mode exercise (RISE; resistance, interval, stretching, endurance) training (PRISE) improves muscular endurance, strength, power and arterial health in exercise-trained women. The current study extends these findings by examining PRISE on fitness, growth hormone (GH), insulin-like growth factor-1 (IGF-1), and brain-derived neurotrophic factor (BDNF) response, cardiometabolic health, and body composition in exercise-trained men. DESIGN: Twenty active males (>4daysexercise/week) completed either: PRISE (n=11) or RISE (5-6meals/day @ 1.0g/kgBW/day; n=9) for 12weeks. Muscular strength (1-repetition maximum bench and leg press, 1-RM BP, and 1-RM LP), endurance (sit-ups ...

BACKGROUND: Plyometric training has been shown to increase muscle power, running economy, and performance in athletes. Despite its use by rowing coaches, it is unknown whether plyometrics might improve rowing economy or performance. The purpose was to determine if plyometric training, in conjunction with training on the water, would lead to improved rowing economy and performance. METHODS: Eighteen male high school rowers were assigned to perform 4 weeks of either plyometric training (PLYO, n = 9) or steady-state cycling below ventilatory threshold (endurance, E, n = 9), for 30 min prior to practice on the water (matched for training volume) 3 days ...

The beneficial cardiometabolic and body composition effects of combined protein-pacing (P; 5-6 meals/day at 2.0 g/kg BW/day) and multi-mode exercise (resistance, interval, stretching, endurance; RISE) training (PRISE) in obese adults has previously been established. The current study examines PRISE on physical performance (endurance, strength and power) outcomes in healthy, physically active women. Thirty exercise-trained women (>4 days exercise/week) were randomized to either PRISE (n = 15) or a control (CON, 5-6 meals/day at 1.0 g/kg BW/day; n = 15) for 12 weeks. Muscular strength (1-RM bench press, 1-RM BP) endurance (sit-ups, SUs; push-ups ...


Comparison Of Ventilatory Measures And 20 Km Time Trial Performance, Willard Peveler 2017 Northern Kentucky University

Comparison Of Ventilatory Measures And 20 Km Time Trial Performance, Willard Peveler

International Journal of Exercise Science

International Journal of Exercise Science 10(4): 640-648, 2017. Performance threshold measures are used to predict cycling performance. Previous research has focused on long time trials (≥ 40 km) using power at ventilatory threshold and respiratory threshold to estimate time trial performance. As intensity greatly differs during shorter time trails applying findings from longer time trials may not be appropriate. The use of heart rate measures to determine 20 km time trial performance has yet to be examined. The purpose of this study was to determine the effectiveness of heart rate measures at ventilatory threshold (VE/VO2 Plotted and VT ...


Effect Of Exercise Training On Microvascular Function In African American And Caucasian Women, Huimin Yan, Keyshla M. Melendex-Rosado, Robert C. Hickner 2017 University of Massachusetts Boston

Effect Of Exercise Training On Microvascular Function In African American And Caucasian Women, Huimin Yan, Keyshla M. Melendex-Rosado, Robert C. Hickner

UMass Center for Clinical and Translational Science Research Retreat

African Americans (AA), especially women, exhibit long-standing disparities in cardiovascular disease (CVD) and obesity. The prevalence of endothelial dysfunction, directly linked to hypertension, is considerably greater in AA than Caucasians (C). Vascular smooth muscle function (mediating endothelium-independent vasodilation) is also related to CVD risk factors but is underappreciated because most literature in C suggest endothelium-independent vasodilatory response is resistance to change with disease (hypertension) or exercise training. Furthermore, the regulation of local skeletal muscle blood flow (an important site of peripheral resistance) has not been sufficiently assessed. Microdialysis is the only method that allows monitoring of microvascular blood flow while ...

International Journal of Exercise Science

International Journal of Exercise Science 10(4): 629-639, 2017. Running economy (RE) and VO2max are important predictors of endurance performance for elite and semi-elite endurance athletes, with RE being an appropriate predictor in a homogenous running population. Altitude training has been observed to change RE (mL.kg-1.min-1), and VO2max due to alterations resulting from acclimatization. This study tracked changes in RE and VO2max before and after a 10-day altitude training camp at 1828 meters. VO2max, RE expressed calorically, and respiratory exchange ratio (RER), were measured below anaerobic threshold (AT ...
