HEART RATE MONITORS

1
HEART RATE MONITORS

• Healthy hearts in the zone
• Lesson 1

2
RESTING (A.M.) HEART RATE

• Take first thing in the A.M.
• Training Effect -The fitter you are the less
  your heart works to do the same activity
• Low resting HR
• Less physiological stress on heart
• Over a lifetime total of heart contractions
  will be lower
• Save more than 700 million heartbeats over life

3
AMBIENT HEART RATE

• Measured when body awake but sedentary
• (sitting position but awake)
• Ranges 50-90 bpm
• Training Effect
• Influenced by
• Body position
• External influences
• Temperature
• Hydration
• Food ingested
• Internal influences
• Fatigue
• Stress
• Hunger
• sleep

AVERAGE AMBIENT HEART RATE
4
DELTA HEART RATE

• The measure of the hearts response to a change
  in body position.
• Usually from sitting to standing
• Standing Heart Rate
• - Sitting Heart Rate
• Delta Heart Rate
• Change in heart rate values occurs when heart
  responds to different work loads
• Higher delta less fit cardio system
• Stress from Internal or external conditions

5
RECOVERY HEART RATE

• Measures the cardiac pumps ability to return to
  normal exercise.
• Better recovery the fitter the person

6
RECOVERY HEART RATE

• 2 TYPES OF RECOVERY
• INTRARECOVERY
• Time it takes for heart to recover w/in 1 workout
  session
• INTERRECOVERY
• Time it takes for heart and specific muscle
  groups to completely recover between workout
  sessions
• Usually recover very quick
• If slow to recover this indicates less fit cardio
  system
• or a warning of heart related conditions

7
MAXIMUM HEART RATE

• Maximum number of times the heart can contract in
  1 min
• FACTS ABOUT MAX HEART RATE
• Genetically determined
• Cant be increased by training
• In sedentary individuals, it declines with age
• In children, usually over 200 bpm
• Tends to be higher in women than men
• Affected by drugs
• High/low max HR doesnt predict better/worse
  performance
• Varies greatly among people of the same age

8
SPORT SPECIFIC MAXIMUM HEART RATE

• It is sport specific
• After the max is reached, one can still increase
  intensity but not heart rate
• Factors for Sport specific max
• Body position
• Size and of muscle groups
• Temp of environment
• Type of activity
• Type of equipment
• Swimming vs running
• Prone position, cold temp smaller upper body
  muscles
