Soc 9: Flashcards
Aerobic exercise
Working at a moderate intensity level with oxygen
Anaerobic exercise
Working at a high level of intensity 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 ( breathing in and out )
Cardiac output
The amount of blood ejected from your heart in one minute ( CO ) = ( RSV ) X ( RHR )
Stroke volume
The amount of blood pumped per beat
Recovery rate
The speed at which your heart returns to RHR after you exercise
What are the long term effects of the musculo-skeletal system?
Increased strength of ligaments and tendons
Increased bone density ( strength and fitness )
Muscular hypertrophy
Adaptation
Long term affects of aerobic training
Will increase the ability to work for long periods of time
Long term affects of anaerobic training
Increase the ability to move in quick bursts
Long term affects on the cardio-respiratory system - your heart
Decreased resting heart rate
Faster recovery rate
Increased resting stroke volume
Maximum cardiac output
Size and strength of the heart
Long term effects on the cardio-respiratory system - your blood
Increased number of capillaries
Increased number of red blood cells
Drop in resting blood pressure
Long term effects on the respiratory system - lungs
Increased lung capacity/ volume and vital capacity
Increased number of alveoli
Increased strength of the diaphragm and external intercostal muscles
