CARDIORESPIRATORY ENDUCANCE

1
CARDIORESPIRATORY ENDUCANCE

• HEART / LUNGS / BLOOD AND THE BODY

2
Cardiorespiratory Endurance

• The most important component of physical fitness,
  and best indicator of overall health.
• The measure of how efficiently our bodies work
  oxygen uptake / distribution and utilization.
• Hypokinetic diseases diseases due to the lack of
  activity.
• Hypertension, heart disease, obesity, cancer
  etc..

3
Aerobic / Anaerobic Exercise

• Anaerobic Exercise
• High intensity exercises.
• Exercise that doesnt need oxygen to produce
  energy.
• 2-3 minutes of high energy bursts.
• 100, 200, 400 meter sprints, weight lifting, etc.

• Aerobic Exercise
• Low to moderate intensity exercises.
• Body requires oxygen to produce energy (ATP).
• Walking, jogging, swimming, cycling, etc.

4
Benefits of Aerobic Exercise

• Higher maximum oxygen uptake
• Increase in oxygen-carrying capacity of the
  blood.
• Decrease in resting heart rate
• Increase cardiac output stroke volume.

• Lower heart rate at given workloads.
• Increase number size of mitochondria.
• Increase number of functional capillaries.
• Increased recovery time.
• Decreased blood pressure blood lipids.

5
Assessing Cardio. Endurance

• Determining maximal amount of oxygen the human
  body is able to utilize in 1 minute.
• 1.5 mile Run Test
• 1.0 Mile walk test
• Step Test (3 min.)
• Astrand-Ryhming Test
• 12-Minute Swim Test

6
Blood Pressure/Heart Rate Assessment

• Find pulse / count 30 seconds / multiply by 2
  resting heart rate / beats per minute (bpm).
• Bradycardia slower heart rate than normal
  (below 40 bpm).
• Systolic Blood Pressure pressure on artery
  walls during heart contractions.
• Diastolic Blood Pressure pressure on arteries
  during rest phase of heart contractions.
