Examination Of Sex- And Limb-Specific Fatigue During Unilateral, Isometric Forearm Exercise, Caleb Christian Voskuil
Examination Of Sex- And Limb-Specific Fatigue During Unilateral, Isometric Forearm Exercise, Caleb Christian Voskuil
Theses and Dissertations--Kinesiology and Health Promotion
The purpose of this study was to examine the effects of unilateral, isometric handgrip holds to failure for the dominant (Dm) and non-dominant (NDm) limb on ipsilateral ([IPS] exercised side) and contralateral ([CON] non-exercised side) performance fatigability. Twenty individuals participated in this study (Men [n =10]; Women [n = 10; Composite Demographics: Age: 22.2 years; Height: 174.4 cm; Body Mass: 75.0 kg) and completed three visits. Two, 6 s maximal voluntary isometric contractions (MVICs) for the Dm and NDm limb were performed during visit 1, followed by a familiarization of the fatigue test. Visits 2 and 3 included an isometric, …
Effects Of Relative Inertial Load On Performance Measures And Quadriceps Electromyography During Flywheel Resistance Training Squats, Jason Todd Brantley Jr.
Effects Of Relative Inertial Load On Performance Measures And Quadriceps Electromyography During Flywheel Resistance Training Squats, Jason Todd Brantley Jr.
Theses and Dissertations--Kinesiology and Health Promotion
Flywheel resistance training (FRT) has become an increasingly popular modality for exercising due to its unique application of providing external resistance. Little is known about how changes in relative inertial loads affects performance and electromyography (EMG) activity. The purpose of this study was to examine how performance metrics and quadriceps EMG activity are affected by relative inertial load during FRT-based squats. Fifteen resistance trained individuals completed five sets of five repetitions of squats with varying relative inertial loads in random order. Peak Eccentric Power (PEP), Peak Concentric Power (PCP), average force, total work, and repetition time were measured. Surface level …
Temporal Neuromuscular Alterations Of The Quadriceps After Unilateral Anterior Cruciate Ligament Reconstruction, Conrad M. Gabler
Temporal Neuromuscular Alterations Of The Quadriceps After Unilateral Anterior Cruciate Ligament Reconstruction, Conrad M. Gabler
Theses and Dissertations--Rehabilitation Sciences
Objective: The primary aim of this research was to examine the temporal pattern of neuromuscular quadriceps deficits in both the involved and uninvolved limbs of patients assigned to the control group after anterior cruciate ligament reconstruction (ACLr), by assessing quadriceps strength, voluntary activation, and corticomotor excitability prior to surgery (baseline), three months after ACLr, and six months after ACLr. A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported function at six …
