1. 1 Honours Projects 2009: Muscle & Exercise Physiology Dr Trevor Allen & Prof Uwe Proske

2. 2 Project 1: Muscle fatigue and limb position sense

3. 3 QUESTIONS How do we know where our limbs are in space when we cant 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

4. 4 MEASUREMENTS - Joint Angle (Position error) - Active Force - EMG

5. 5 Project 2: Effect of exercise and stretch on passive and active tension in human skeletal muscle

6. 6 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

7. 7 - Passive Torque - Active Torque - EMG MEASUREMENTS
