Winning In Weight-Loss: The Interaction Of Conscientiousness And Perceived Autonomy, Jason M. Curtis, Marc Lochbaum

Journal for Sports Neuroscience

ABSTRACT

Background

Understanding determinants for weight-loss is a national priority. Obesity is an epidemic with serious health consequences. Most of today’s obesity and overweight problems are being attributed to poor diets and not enough physical activity. These problems show no signs of slowing down with the behaviors of most Americans. The phenomenon of “The Biggest Loser” (different variants of weight-loss programs that consist of group exercise participation and nutrition therapy to elicit weight-loss, and hopefully behavior change) has spawned many variants in commercial health clubs. This prospectus study examined the direct and interactive or moderated effects of known determinants of …

The Effects Of Medial Gastrocnemius Muscle Fatigue On Regional Modulation Of The Ankle Plantarflexors During Standing External Perturbations, Nicole D. Grzywnowicz

Electronic Thesis and Dissertation Repository

The ankle plantarflexor muscles (soleus, medial, and lateral gastrocnemius) exhibit direction-specific regional modulation of muscle activity during external perturbations. This study sought to investigate the effect of medial gastrocnemius muscle fatigue on plantarflexor muscle activation patterns. Unipedal balance was tested during external perturbations that challenged standing balance in different directions before and after low-frequency fatigue was induced to the medial gastrocnemius via electrical stimulation. High-density surface electromyography was used to determine the amplitude and barycenter of muscle activation. It was hypothesized that the central nervous system would compensate for a loss of force-generating capacity in the medial gastrocnemius by modulating …
