The Effect Of Repeated Heat Stress On Mitochondrial Protein Content In Human Skeletal Muscle, Amy Twitchell, Robert Hyldahl
The Effect Of Repeated Heat Stress On Mitochondrial Protein Content In Human Skeletal Muscle, Amy Twitchell, Robert Hyldahl
Journal of Undergraduate Research
Exercise has been known to improve mitochondrial function and increase its content in muscle. However, those who suffer from certain diseases such as Chronic Obstructive Pulmonary Disease (COPD) and Type II Diabetes often experience concomitant exercise intolerance. In vitro research suggests that the application of a mild heat stress may be sufficient to activate some of the same signaling proteins that become active during exercise, possibly leading to mitochondrial biogenesis in skeletal muscle. However, this has not yet been confirmed to occur in human skeletal muscle. Therefore, the purpose of this study was to investigate the effect of heat therapy …
Effect Of Restricted Ankle Mobility On Muscle Reaction Time And Ankle Joint Kinematics To A Simulated Ankle Sprain During Walking In Chronic Ankle Instability Patients, Brandon Winward, Ty Hopkins
Effect Of Restricted Ankle Mobility On Muscle Reaction Time And Ankle Joint Kinematics To A Simulated Ankle Sprain During Walking In Chronic Ankle Instability Patients, Brandon Winward, Ty Hopkins
Journal of Undergraduate Research
Inversion ankle sprains are common and are caused by sudden inversion stresses during weight-bearing movement which causes the foot to roll under and inward.1 Ankle sprains result in tearing or stretching of ligaments and muscles, which reduces ankle stability.2 After a single ankle sprain, up to 80% of people suffer repeated sprains, which often develop into chronic ankle instability (CAI).3 Research has shown CAI patients often exhibit delayed lower leg muscle reaction time and restricted dorsiflexion range of motion (DROM).2

Satellite cells are the progenitor stem cells of skeletal muscle (SM) that reside between the sarcolemma and basal lamina. This space is referred to as the satellite cell niche. Following injury, quiescent satellite cells are activated, proliferate then migrate and fuse to the injured region of muscle to support regeneration (3). Satellite cells in muscle tissue from older subjects migrate at less than half the speed of those in young tissue (2). This may contribute to the diminished regenerative response observed in older subjects. Tenascin C (TNC) has been identified as a de-adhesion protein that is upregulated in the satellite …
