Coordination Between Autophagy And The Heat Shock Response: Evidence From Exercise In Animals And Humans, Nathan H. Cole
Coordination Between Autophagy And The Heat Shock Response: Evidence From Exercise In Animals And Humans, Nathan H. Cole
Health, Exercise, and Sports Sciences ETDs
Proteins play a critical role in nearly every biological activity. In consequence, organismal health and homeostasis often hinges on the ability of intracellular regulatory systems to sustain the quality and function of these diverse, structurally complex macromolecules. Correct protein function depends on correct form, and during periods of destabilizing cellular stress, protein quality is managed in part by the heat shock response, which acts to support, isolate, and reform new or damaged proteins, and in part by the autophagic recycling of abnormal proteins, cytotoxic protein aggregates, and terminally damaged organelles. We conducted a pooled analysis of available research in humans …
Effects Of Eccentric Contraction Duration On Muscle Strength, Power Production, Vertical Jump And Soreness, Jonathan N. Mike
Effects Of Eccentric Contraction Duration On Muscle Strength, Power Production, Vertical Jump And Soreness, Jonathan N. Mike
Health, Exercise, and Sports Sciences ETDs
Prior research has investigated the effects of either eccentric-only training or comparing eccentric and concentric exercise on changes related to strength and power expression, but no research to date has investigated the impact of altering the duration of either the concentric or eccentric component on these parameters. Therefore, the purpose of this study was to assess the duration of eccentric (i.e. 2-second, 4-second vs. 6-second) muscle contractions and their effect on muscle strength, power production, vertical jump and soreness using a plate-loaded barbell Smith squat exercise. Thirty college-aged males (23 ± 3.5 years, 178 ± 6.8 cm, 82 ± 12 …
The Effects Of Gait Retraining In Runners With Patellofemoral Pain, Jenevieve Roper
The Effects Of Gait Retraining In Runners With Patellofemoral Pain, Jenevieve Roper
Health, Exercise, and Sports Sciences ETDs
Running popularity has increased resulting in a concomitant increase in running-related injuries. Of these injuries, patellofemoral pain (PFP) is the most commonly reported. PURPOSE: The purpose of this study is to determine whether gait retraining by modifying footstrike patterns from rearfoot strike (RFS) to forefoot strike (FFS) reduces PFP and improves associated biomechanical measures, and whether the modification results in increased risk of ankle injuries. METHODS: Sixteen subjects (n=16) received clearance to participate by a licensed physical therapist, and were randomly placed in the control (n=8) or experimental (n=8) group. Subsequently, the experimental group (EXP) performed eight gait retraining running …
