Power Reserve Following Ramp-Incremental Cycling To Exhaustion: Implications For Muscle Fatigue And Function, Michael D. Hodgson
Power Reserve Following Ramp-Incremental Cycling To Exhaustion: Implications For Muscle Fatigue And Function, Michael D. Hodgson
Electronic Thesis and Dissertation Repository
In ramp-incremental cycling exercise, some individuals are capable of producing power output (PO) in excess of that produced at their limit of tolerance (LoT) while others cannot. This study sought to describe the: 1) prevalence of a “power reserve” within a group of young men (n=21; mean ± SD: age 25±4 years; V̇O2max45±8 ml•kg-1•min-1); and 2) muscle fatigue characteristics of those with and without a power reserve. Power reserve was determined as the difference between peak PO achieved during a ramp-incremental test to exhaustion and maximal, single-leg isokinetic dynamometer power. Pre- versus post-exercise changes …
E-Visits For Early Post-Operative Visits Following Orthopaedic Surgery Can They Add Efficiency Without Sacrificing Effectiveness, William G. Jeffery
E-Visits For Early Post-Operative Visits Following Orthopaedic Surgery Can They Add Efficiency Without Sacrificing Effectiveness, William G. Jeffery
Electronic Thesis and Dissertation Repository
We asked 217 sport surgery and 135 total knee arthroplasty (TKA) patients to complete a questionnaire (e-Visit) before attending their two and six-week post-operative appointment. Our primary objective was to use the questions asked of patients prior to their appointment to develop a model that could be used as web-based e-Visit to predict early post-operative adverse events. Gold standard comparison was the surgeon’s opinion as to the presence or absence of an event at follow-up. Secondary objective was evaluation of a simplified model. We found good area under the curve (AUC) statistics (0.76 (95% CI 0.69 - 0.84) and 0.80 …
The Effects Of Moderate Intensity Strength Training Coupled With Blood Flow Restriction: A 12 Week Intervention, Kelly Barrett
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 per …
The Responses Of Vo2, Vco2, Substrate Utilization And Maximal Performance To Long Duration Exercise, Michael Bitel
The Responses Of Vo2, Vco2, Substrate Utilization And Maximal Performance To Long Duration Exercise, Michael Bitel
Electronic Thesis and Dissertation Repository
Purpose: The purpose of this study was to compare and contrast the effects of a long duration exercise cycle (~3 h) by trained cyclists (RIDE) to a 3 h inactive period (SED) in recreationally active individuals (CONT) on VO2, VCO2, peak aerobic power, fat oxidation, anaerobic capacity (Wʹ), arterialised-capillary lactate concentration and maximal sustainable power (CP). Methods: Male cyclists (n=12) and male recreationally active individuals (n=7) performed both an incremental test to volitional fatigue (RAMP) and 3 min all-out tests on a cycle ergometer, pre- and post-RIDE/SED respectively. Results: Increased fat oxidation rates, and reductions in VO2peak, peak aerobic power …
