    Research Overview

    My research spans the organism, tissue, cellular and molecular levels and typically combines in vivo and in vitro approaches to investigate the impact of aging, exercise, disease, and changes in loading environment on structure-function relationships in skeletal muscle and tendon. A decrease with aging in muscle mass results from a loss of muscle fibers due to a loss of motor units. In addition to the muscle atrophy, unexplained muscle weakness remains when force is normalized by muscle cross-sectional area. The cellular and molecular mechanisms underlying muscle atrophy and weakness are studied in aging rodents. The mechanisms underlying differences in susceptibility to injury of muscles and tendons are also under active investigation. Exercise-induced skeletal muscle injury is initiated by the mechanical disruption of the muscle fiber ultrastructure. The initial mechanical damage initiates a cascade of events including an inflammatory response and degeneration of the damaged fibers. Understanding the tissue, cellular, and molecular adaptations responsible for the protection from injury provided by exercise training, especially the role of inflammation in initiating protective adaptations, is of particular interest.
