Concepts to learn
• What is the relationship between cellular
respiration and heat production?
• How are lactic acid, oxygen debt, and
muscle fatigue related?
• Compare/contrast ATP production in
aerobic respiration and anaerobic
respiration
Thinking Critically
• An Olympic sprinter typically has more
than 80% fast twitch muscle fibers.
• An Olympic marathoner typically has more
than 90% slow twitch muscles.
• An average person has about half fast
twitch and half slow twitch muscles.
• ** Explain the reasoning behind these
statistics.
