SOC 9 - LONG TERM EFFECTS OF EXERCISE Flashcards
Adaptation
Your body’s response to training and how your body changes to cope with new activity.
Aerobic
Working at a moderate intensity level with oxygen.
Anaerobic
Working at a high intensity level without oxygen.
Alveoli
Tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream.
Diaphragm
The primary muscle used in the process of inspiration or inhalation.
Cardiac output
The amount of blood ejected from your heart in one minute (CO) = (SV) x (HR)
Resting stroke volume
The amount of blood pumped per beat.
Recovery rate
The speed at which your heart returns To RHR after you exercise.
What is aerobic exercise
working at a moderate intensity level with oxygen.
What are the effects for increasing the time you train for ( aerobic )
• Improved times for long distance athletes (5,000m, 10,000m, marathon runners etc.).
•Ability to run for 90 minutes during a football game (improve cardiovascular fitness levels).
what is anaerobic exercises
working at a high intensity level without oxygen.
What are some effects if you increase the ability to move quick
• Sprinting for the ball in football.
• Making a powerful tackle in a rugby game.
• Improved time over the shorter/ sprint distances in athletics or swimming.
What is meant by lung capacitie
How much volume your lungs can hold
What is vital capacitie
Total amount of oxygen exhaled when you breathe in
What are some effects of the musculo-skeletal system
• Increased strength of ligaments and tendons.
• Increased bone density – helps prevent osteoporosis (weakening of bones).
• Muscle hypertrophy: is a term for the growth and increase of the size of muscle cells.
• Adaptation: the body adapts to training loads imposed on it by increasing the ability
to cope with those loads.
Decreased resting heart rate
Your heart gets bigger/ stronger with training, so it can supply the same amount of blood with fewer beats.
Faster recovery rate
Heart recovery rate is the speed at which your heart returns to RHR after you exercise. The faster your recovery rate, the fitter you are.
Increased stroke volume
Stroke volume is the amount of blood pumped by your heart per beat . When you exercise regulary, your stroke volume increases, both at rest and work
Maximum cardiac output
The amount of blood ejected from your heart in one
minute. Cardiac output (CO) = stroke volume (SV) X heart rate (HR).
Size and strength of the heart
Training increases the heart muscles in size,thickness and strength.
