Title: Chapter Seven Cardiovascular Fitness


1
Chapter SevenCardiovascular Fitness
  • Cardiovascular Fitness Facts Building
    Cardiovascular Fitness
  • Pgs 103-112

2
Cardiovascular Fitness
  • Of all the parts of fitness, cardio is the MOST
    important
  • It has the most health and wellness benefits for
    a longer life

3
Benefits of Physical Activity and Cardiovascular
Fitness
  • Regular physical activity benefits two vital body
    systems the cardiovascular system and
    respiratory system

4
Heart
  • The heart is a muscle and benefits from activity
  • Your heart is a pump that supplies blood to cells
  • During exercise, your pump must pump more blood
    to supply oxygen
  • Fit Heart more blood with fewer beats
  • Unfit Heart less blood with more beats

5
Blood
  • Blood contains
  • 1. Cholesterol a fatlike substance
  • 2. Low-density lipoproteins (LDL) are BAD
  • 3. High-density lipoproteins (HDL) are GOOD
  • 4. Fibrin-a substance that makes the blood clot

6
Arteries
  • Arteries carry blood away from the heart
  • Fat deposits can block arteries and cause
    atherosclerosis
  • Extreme atherosclerosis can lead to a heart attack

7
Veins
  • Veins carry blood back to the heart
  • One-way valves in the veins keep blood from
    flowing backward
  • Exercise increases the efficiency of these valves

8
Nerves of Your Heart
  • The heart pumps involuntarily (your brain does
    not tell it to pump)
  • The heart is controlled by electrical currents
  • Fit people have low resting heart rates

9
Cardiovascular Assessment
  • Mile run/walk
  • PACER
  • Step Test
  • Walk Test

10
Cardiovascular Fitness
  • Building Cardiovascular Fitness
  • Pgs 110-112

11
Aerobic Activity
  • Aerobic means with oxygen
  • Continuous activities allow the heart to supply
    oxygen to the muscles
  • Needs to be vigourous enough to raise heart rate
    in THRZ

12
FIT Formula for Cardio
13
Calculating Maximal Heart Rate
  • Maximal Heart Rate 208 (.70 x your age)
  • Maximal Heart Rate is your target ceiling
  • 13 years199 bpm
  • 14 years198 bpm
  • 15 years197 bpm
  • 16 years197 bpm

14
Calculating THRZ (Heart Rate Range Method)
15
Anaerobic Activity
  • Anaerobic activity is intense, short bursts of
    energy
  • Examples include, sprinting, jumping,
    weightlifting, and football
  • You need frequent rests to catch your breath
