  2. Exercise physiology • Objectives: • Exercise as external stresses • Body response to exercise. • Adaption to long term exercise. • Measurement of some physiological parameters during exercise.

  3. The musculoskeletal system and exercise

  4. Types of muscle fibers: Fast twitchSlow twitch Diameter. Larger in diameter --------- Enzymes releasing 2-4 time more active energy Number of capillaries -------------- far more than fast fibers Type of the exercise short time exercise endurance (second or minute) (hours) Mitochondria and -------------- much more myoglobin than fast fibers “Heredity differences”

  5. % of fast and slow twitch fibers in average man and in different types of sports.

  6. Strength power and endurance: Strength: is the maximum contractile force by the muscle, depend mainly on the size and measured by (kg /cm2). Power: is the total work den by the muscle per unit period of time. Endurance : is the final measure of muscle performance, and depend upon the glycogen content of the muscle

  7. Type of diet and muscle endurance
