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 …
A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan
A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan
Electronic Thesis and Dissertation Repository
Attention Restoration Theory (ART) predicts that top-down processing during everyday activities can cause attentional fatigue and that bottom-up processing that occurs when people experience nature will be restorative (Kaplan, 1995). The present study examined this prediction by exposing participants to three different conditions using a repeated measures design: a control condition during which participants walked on a typical treadmill, a nature/restorative condition during which participants walked on the same treadmill, experiencing a simulated nature walk, and a perturbation condition that included the same simulated nature scene but also required top-down processing during the walk. The findings supported ART predictions. As …
Behaviour Change Intervention Strategies To Prevent Excessive Gestational Weight Gain In Pregnant Women Using A Nutrition And Exercise Lifestyle Intervention Program (Nelip), Karishma Hosein
Electronic Thesis and Dissertation Repository
Maternal obesity and excessive gestational weight gain (EGWG) are associated with adverse maternal and fetal outcomes. To evaluate the effectiveness of different behaviour change intervention strategies, it was hypothesized that the introduction of a single behaviour change, followed by a second, would be more effective at preventing early and total EGWG in pregnant women compared to the early simultaneous introduction of both behaviour changes. Eighteen pregnant women were block randomized into one of 3 Nutrition and Exercise Lifestyle Intervention Program (NELIP) strategies (full NELIP, Nutrition followed by Exercise N+E, Exercise followed by Nutrition E+N) and were followed at weekly face-to-face …
Insulin Resistance And T1d: The Effect Of Exercise On Skeletal Muscle Lipid Metabolism, Michelle Dotzert
Insulin Resistance And T1d: The Effect Of Exercise On Skeletal Muscle Lipid Metabolism, Michelle Dotzert
Electronic Thesis and Dissertation Repository
Insulin resistance is a characteristic of Type 2 Diabetes (T2D) and metabolic syndrome, and until recently has not been considered in the context of Type 1 Diabetes (T1D). A new classification, Double Diabetes, encompasses the presence of insulin resistance in T1D. Unfortunately, these individuals are at significantly higher risk of cardiovascular complications than those with T1D alone. In T2D, abnormal skeletal muscle lipid metabolism and the accumulation of insulin desensitizing lipid metabolites contribute the development of insulin resistance. There is some evidence to suggest this occurs in the context of T1D as well. Exercise training is an effective means to …
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 …
