Summary
It is well recognized that sedentary life styles are associated with increased incidence of obesity, Type 2 diabetes and atherosclerotic cardiovascular disease. The medical, social and financial costs of these diseases are growing rapidly and represent a major health care challenge. Exercise is beneficial for maintaining health in patients at risk of developing these diseases and for this reason we are interested in understanding how exercise capacity is regulated.
Physiological And Pathological Effects Of Oxidation On Contractile Function In Skeletal Muscle

Funding Amount

Summary
Reactive oxygen molecules generated within muscle fibres in normal exercise and in pathological conditions, greatly affect muscle function by altering the responsiveness of the contractile proteins. This study investigates how various oxidative stresses affect particular reactive sites on key proteins controlling muscle contraction. The findings should identify key molecular changes involved in normal activity and the role oxidation plays in chronic muscle weakness in particular conditions.
Excitation-contraction Coupling In Skeletal Muscle In Health, Exercise And Disease

Summary
Skeletal muscle dysfunction occurs in certain diseases, aging and exercise, and can deleteriously affect lifestyle and mobility. This project investigates the molecular mechanisms involved in the complex sequence of events that occur in each individual muscle fibre, starting from stimulation by a nerve through to the fibre contracting. This should give information about causes of skeletal muscle dysfunction in myotonia, heart failure and other situations, and help development of therapies.
