Think – Pair – Share
Discuss with your friend (behind/next to you) which part of the exercises (A or B)
need more energy? Why and what makes them different?
What is the form of energy that is needed by those exercises?
Discuss & Find Out
• Why sprinter is using more energy from anaerobic respiration rather than aerobic?
• Do the muscle fibres of marathon and sprinter athletes are the same? Why?
Anaerobic
ATP – PC System (10’’)
Lactic Acid System (10”- 20”)
C6H12O6 → 2 C3H6O3 + Energy (2 ATP)
Glucose → 2 Lactic Acid + energy
Self Assessment
• Type of muscle cells and their differences, blood cell & nerve cell• Respiration process• Type of respiration• Gas exchange process• Type of heart chamber and their function, blood vessel • Blood circulation movement• The connection of exercise, circulatory system, body heat, respiration
system and diffusion rate• The connection of slow / fast twitch, type of respiration (aerobic /
anaerobic) and type of exercise• The process of ATP is being produced in muscle, by – product and its effect• The process of muscle movement, reflex movement
