Cardiorespiratory Endurance Flashcards
Define cardiorespiratory fitness.
the ability of the heart and lungs to deliver oxygenated blood and nutrients to active tissues and remove waste products
What does cardiorespiratory fitness rely on?
- respiratory system
- cardiovascular system
- musculature
- metabolic pathways
Define heart rate.
amount of beats per minute
Define stroke volume.
blood pumped per beat
Define cardiac output.
- amount of blood pumped per minute
- HRxSV
- more blood pumped per minute = less beats, heart gets a break
Heart rate and stroke volume are _________.
inversely proportional
Heart rate and cardiac output are _________.
inversely proportional
Stroke volume and cardiac output are ________.
proportional
Muscles activated depends on:
- intensity of exercise
- duration of exercise
What is metabolism?
- processes occurring within the cell
- enable the formation of ATP
- ATP = energy
What can we use to make ATP?
- carbohydrates: glucose, glycogen = ATP
- fat: triglycerides (adipose tissue) = ATP
- protein: breakdown of amino acids = ATP (does not normally occur)
What are the benefits of cardiorespiratory endurance training (7)?
- decreased resting HR, improved efficiency of the heart
- blood pressure
- blood lipids
- capillaries
- metabolic efficiency
- mitochondria
- VO2 max, performance benefits
Name 4 performance related benefits of cardiorespiratory endurance and VO2 max.
- VO2 max: the maximal ability of the body to take up, transport, and utilize oxygen
- measure of fitness
- can be estimated
- correlated to performance measures (enhanced VO2 = enhanced performance)
