Honours Projects 2009: Muscle & Exercise Physiology Dr Trevor Allen & Prof Uwe Proske 1 Project 1: “Muscle fatigue and limb position sense” 2 QUESTIONS • How do we know where our limbs are in space when we can’t see them? • What is the interaction between command signals from the brain and sensory signals from the muscle? IMPLICATIONS • Reduce incidence of fall-related injuries • Reduce fatigue-related impairments in sport performance 3 MEASUREMENTS - Joint Angle (Position error) - Active Force - EMG 4 Project 2: “Effect of exercise and stretch on passive and active tension in human skeletal muscle” 5 QUESTIONS • Are there any benefits of stretching with respect to injury prevention and performance? • What mechanisms are responsible for changes in muscle tension after stretching, warm-up and exercise? IMPLICATIONS • Reduction in exercise-induced injuries • Improvements in sport performance 6 MEASUREMENTS - Passive Torque - Active Torque - EMG 7 Muscle & Exercise Physiology Contact Details: Trevor: [email protected] Uwe: [email protected] Exercise Physiology Lab (THUR & FRI) Physiology Ground Floor – Rm FG22 Tel: 9905 2543 8
