Study Notes
Cardiac Output
- Heart rate measures the number of heartbeats per minute.
- Maximum heart rate is approximately 200 minus age.
Aerobic and Anaerobic Respiration
- Digestion is the process of breaking down food in the gut.
- Glycogen is a stored form of glucose in the liver and muscles, providing immediate energy for muscles.
- Aerobic respiration: Glucose + Oxygen → Water + Carbon Dioxide + Energy
- Anaerobic respiration: Glucose → Lactic Acid + Energy
Recovery
- Oxygen debt is a temporary oxygen shortage in tissues caused by exercise.
- EPOC (Excess Post-exercise Oxygen Consumption) is the body's uptake of additional oxygen to remove lactic acid from anaerobic respiration.
Factors Affecting Fast Recovery
- Overall strength and fitness level
- Genetics
- Age
- Gender
- Sleep quality
Therapies for Recovery
- Hot and cold contrast therapy
- Massage therapy
Short-Term Effects of Exercise
- Increased skin temperature and redness
- Sweating
- Fatigue
- Nausea
- Lightheadedness
Long-Term Effects of Exercise
- Increased heart size
- Bradycardia (slow heart rate, a benefit of long-term exercise)
Principles of Force
- Force is a push or pull applied to an object.
- Newton's First Law of Motion: Objects remain at rest or in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- Newton's Second Law of Motion: Acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Newton's Third Law of Motion: For every action, there is an equal and opposite reaction.
Applications of Force
- Gravity: The force of attraction between any two objects with mass, pulling them towards each other.
- Muscular Force: A push or pull produced by muscle contraction.
- Air Resistance: A frictional force opposing the motion of an object through the air.
Levers
- Resistance: The load or weight that the lever must move.
- Fulcrum: The fixed point around which the lever pivots.
- Effort: The force required to move the load.
