The Effect Of Postural Perturbations On Cardiovascular And Skeletal Muscle Function In Healthy Adults, Patrick Siedlecki
The Effect Of Postural Perturbations On Cardiovascular And Skeletal Muscle Function In Healthy Adults, Patrick Siedlecki
Electronic Thesis and Dissertation Repository
Maintenance of standing balance is vital to daily living. Traditionally, perspectives on maintaining balance are achieved through the study of visual, vestibular and somatosensory inputs on motor outputs. While evidence suggests cardiovascular regulation also functions to assist postural control during orthostatic stress, how the cardiovascular system responds to postural perturbations is not well established. This dissertation includes four studies that investigated the effects of postural perturbations on the cardiovascular system and skeletal muscle responses in healthy adults. All of the studies involved exposing standing participants to surface-translation perturbations at different velocities, with known or unknown timing, and occurred while spontaneously …
A Biomechanical Analysis Of Back Squats: Motion Capture, Electromyography, And Musculoskeletal Modeling, Eva Maria Urdiales Maddox
A Biomechanical Analysis Of Back Squats: Motion Capture, Electromyography, And Musculoskeletal Modeling, Eva Maria Urdiales Maddox
Human Movement Sciences & Special Education Theses & Dissertations
Previous literature evaluating maximal back squats have failed to identify key components of the study decisions and procedures that would allow for duplication. Firstly, the existence of a sticking region in maximally weighted resistance exercises is frequently discussed and has been described as a force-reduced transition phase between an acceleration phase and a strength phase of a lift. However, the etiology has yet to be agreed upon. Second, Electromyography (EMG) is frequently used to assess muscle activations. However, no best practice for EMG normalization has been proposed. Two methods are commonly implemented for normalizing EMG: a maximum voluntary isometric contraction …
The Effects Of Common Low-Load Blood Flow Restriction Training Protocols On Muscle Excitation And Fatigue, Taylor M. Aldeghi
The Effects Of Common Low-Load Blood Flow Restriction Training Protocols On Muscle Excitation And Fatigue, Taylor M. Aldeghi
Honors Undergraduate Theses
Low-load blood flow restriction (LLBFR) training has been shown to elicit greater increases in muscle hypertrophy and strength compared to traditional low-load training, yet few studies have compared the effectiveness of different LLBFR protocols. To our knowledge, no previous study has compared the acute neuromuscular changes induced by two common LLBFR protocols: 30-15-15-15 repetitions (BFR-75) and four sets of repetitions performed to volitional failure (BFR-F). Therefore, the purpose of this study was to use surface electromyography (sEMG) to compare changes in muscle excitation and fatigue during BFR-75 and BFR-F protocols. Ten women (mean ± SD age = 22 ± 3.5 …
