The Combined Influence of Pedal Rate and Venous Distension on Exercise Activation of Locomotor Afferents and Cardiovascular Responses
Rochester, MN
The first purpose is to investigate the effect of pedal rate during submaximal exercise activation of locomotor muscle afferents on ventilation, gas exchange, blood pressure, and cardiac hemodynamic responses in healthy individuals compared with HF patients. We will determine the influence of pedal rate on ventilation, gas exchange, blood pressure, and cardiac hemodynamic responses on activation of group III and IV locomotor muscle afferents using a novel application and integration of two separate but related scientific questions to better understand peripheral mechanisms of exercise tolerance in humans. The second purpose is to investigate whether pedal rates during exercise with activation ...

A Study of Muscle Activation of Shoulder Complex and Spine Stabilizers during the Standard Push-up and Pushing Exercises using a Suspension Strap Training System
Rochester, MN
Physical therapists, personal trainers, and strength and conditioning specialists spend substantial time teaching clients how to strengthen their core. Core muscles provide a stable base for limb movement. Little research has been done looking at specific core and extremity muscle activation with variations of push-up exercises, specifically using the TRX© suspension system.

Effect of Timing of Commencement of BIS Monitoring in Relation to Muscle Relaxant Administration
Rochester, MN
The primary objective of this study is to determine if the commencement of BIS monitoring relative to the administration of muscle relaxants has any effect on BIS values. The current study is a continuation of the project: “Bispectral Index: A Comparison of Bifrontal Montage Agreement” by Dr. Matthew Ritter and Wade Kreun, SRNA which validated the concurrent bifrontal use of BIS sensors. BIS monitors are FDA approved to assess the depth of sedation by analyzing segments of electroencephalogram (EEG) waves. They consist of a sensor, a digital signal converter, and a monitor. A BIS score is not a physiologic measurement, ...
