Soc 9 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.
Aerobic exercise
working at a moderate intensity level with oxygen.
Anaerobic exercise
working at a high intensity level without oxygen.
Positives of long term exersices (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).
Positives on anaerobic exersices
• 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.
. 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.
Effects on the cardio-respiratory system - your heart
Decreased resting heart rate
Faster recovery rate
Increased resting stroke volume
Size and strength of the heart
Maximum cardiac output:
Effects on the cardio-respiratory system - your blood
Capillaries
Increased number of red blood cells
Drop in resting blood pressure
