Soc 9 Flashcards
Size and strength of the heart
training increases the heart muscles in size, thickness and strength.
Stroke volume
stroke volume is the amount of blood pumped by your heart per beat.
Decreased resting heartrate
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.
Anaerobic
Working at a high intensity level without oxygen.
Aerobic
Working at a moderate intensity level with 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) × (HR)
Recovery Rate
The speed at which your heart returns To HR after you exercise.
Long term effects of exercise on your blood
-Faster recovery rate
-Increased number of red blood cells
-drop in resting blood pressure
Long term effects of exercise on the heart - cardio respiritory system
-increased size and strength of heart
-stroke volume(more blood pumped round body)
-decreased resting heart rate
Long term effects of exercise on lungs - respiritory system
-increased lung capacity
-increased number of alveoli
-increased strength of diaphram
Long term effects of exercise on the muscular skeletal system
-increased bone density
-increased strength of tendons and ligaments
-muscular hypertrophy
