Causes of High Blood Pressure
The maximum heart rate (HRmax) is the highest heart rate an individual can achieve without
severe problems through exercise stress and generally decreases with age

• Chronic inactive lifestyle
• High sodium and high fat diets
• Alcohol and tobacco use
• Contraceptives
• Hormone therapy
• Multistage test (2-4 3 min stages)
• Cadence of 50 rev/min

• Test concludes when two consecutive stages have HR >110bpm
Greatest rate at which oxygen can be taken up, distributed, and used by the body during
physical activity
,Definition 5 of 88

Definition 6 of 88

, Term 7 of 88
Heart rate
- Speed of the heartbeat measured by thenumber of contractions (beats) ofthe heart per
minute (bpm)
- Varies according to the body's physical needs,including the need to absorb oxygen
andexcrete carbon dioxide
The maximum heart rate (HRmax) is the highest heart rate an individual can achieve without
severe problems through exercise stress and generally decreases with age
- Determine the ability to perform a specific work task& and physiological responses at rest
and during exercise
- Provide a basis for exercise programming and progress toward goals
- Screen for medical conditions such as CHD
- GOLD STANDARD
- Weighing a person fully submerged in water
- Calculates total body density
- Two-compartment model
Term 8 of 88
What affects heart rate
- Cheaper
- Less equipment
