Understanding Limb Position & Muscle Tension: Implications for Performance & Injury Prevention

Explore the interaction between command signals from the brain and sensory feedback from muscles in relation to limb position awareness and muscle fatigue. Investigate benefits of stretching on muscle tension, injury prevention, and sport performance enhancements.

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

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

  3. 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

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

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

  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. MEASUREMENTS • Passive Torque • Active Torque • EMG
