Physiological indicators - blood pressure, BMI, resting heart rate Flashcards
Physiological indicators - blood pressure, BMI, resting heart rate
Blood pressure - short term risks (high/ low blood pressure)
- low blood pressure: dizzy, light -headed, fainting, falling, accidents,, injury, tiredness, cold/clammy skin
- high blood pressure: headaches, tiredness, shortness of breath, blurred vision
Physiological indicators - blood pressure, BMI, resting heart rate
Blood pressure - long term risk (high/ low blood pressure)
- low blood pressure: heart problems, stroke
-high blood pressure: cardiovascular disease, stroke, vision loss, vascular dementia
Physiological indicators - blood pressure, BMI, resting heart rate
Blood pressure: what is blood pressure?
- pressure exerted by your blood against the walls of your arteries.
- measured in millimetres of mercury (mmHg)
Physiological indicators - blood pressure, BMI, resting heart rate
Blood pressure: what are the top and bottom numbers of your blood pressure reading?
- top: systolic pressure - maximum pressure in arteries as heart pumps blood around body
- bottom: diastolic pressure - minimum pressure as heart relaxes between beats
Physiological indicators - blood pressure, BMI, resting heart rate
Blood pressure: what are the categories of blood pressure?
- low: 90/60 mmHg or lower
- ideal: 90/60 mmHg to 120/80 mmHg
- pre-high: 120/80 mmHg to 140/90 mmHg
- high: 140/90 mmHg or higher
Physiological indicators - blood pressure, BMI, resting heart rate
BMI: what is BMI?
- Measure of the amount of fat on your body in relation to your height to tell you if you are a healthy weight.
- Body Mass Index
Physiological indicators - blood pressure, BMI, resting heart rate
BMI: how do you work out BMI?
- Divide weight in kg by height
Physiological indicators - blood pressure, BMI, resting heart rate
BMI: classifications
- underweight: 18.5 kg/ metres squared
- healthy weight: 18.5 to 24.9 kg/metres squared
- overweight: 25 to 29.9 kg/metres squares
- obese: 30 to 39.9 kg/metres squared
- severely obese: 40 kg/metres squared or over
Physiological indicators - blood pressure, BMI, resting heart rate
BMI: impacts of obesity/ severe obesity
- increased risk heart attack: arteries build up of fatty deposits (cholesterol)
- increased risk stroke: blood clot travel to brain
- increased risk cancer: fat cells contribute to excess cell growth
- increased risk arthritis: increased mass extra strain on joints
Physiological indicators - blood pressure, BMI, resting heart rate
Resting heart rate: what is pulse rate and how to measure it
- pulse rate: measure of how fast your heart is beating
- how to measure: tips two fingers on radial pulse on your wrist, count how many beats in 30 seconds and times by two
Physiological indicators - blood pressure, BMI, resting heart rate
Resting heart rate: classification of data
- average of adult: 60-100 bpm
- average of athlete: 40-60 bpm
- the fitter you are, lower resting heart rate (as heart more efficient)
Physiological indicators - blood pressure, BMI, resting heart rate
Resting heart rate: short term risks (high/ low resting heart rate)
- low: very fit, fainting, light headed
-high: hot, sweaty, out of breath quickly, dizziness, palpatations, linked to lifestyle (smoking, drug use, alcohol, low physical activity)
Physiological indicators - blood pressure, BMI, resting heart rate
Resting heart rate: long term risks (high/ low resting heart rate)
- low: heart failure
- high: stroke, heart attack, high blood pressure, premature death, cardiovascular disease.
Physiological indicators - blood pressure, BMI, resting heart rate
Resting heart rate: recovery after exercise and how to calculate predicted maximum pulse rate
- pulse rate increases after exercise then returns
- predicted max pulse rate: 220 - your age
- healthy pulse rate after exercise is 60 to 80 percent
Physiological indicators - blood pressure, BMI, resting heart rate
State the correct classification for normal resting heart rate.
60 - 100 bpm
Physiological indicators - blood pressure, BMI, resting heart rate
State what is meant by ‘Heart rate recovery after exercise’ as a physiological indicator.
The faster the heart rate recovers after exercise, the fitter the person is
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a high resting heart rate could impact current physical health.
Heart palpitations – due to the heart working too hard.
Fitness can decrease – because it will be difficult to exercise.
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a high resting heart rate could impact future physical health.
Cardiovascular disease – due to damaged arteries.
High blood pressure – due to the additional pressure on the artery walls.
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a low resting heart rate could impact current physical health.
Fainting/light headedness – due to reduced blood flow to the brain.
Fatigue/tiredness – due to reduced oxygen/nutrients to the muscles and organs.
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a low resting heart rate could impact future physical health.
Heart failure – due to the heart becoming weaker over time.
Increased risk of stroke – due to a decrease in blood flow to the brain, it can lead to blood clots.
Improved cardiovascular fitness – due to the heart being more efficient at pumping blood with less beats.
Physiological indicators - blood pressure, BMI, resting heart rate
State the correct classification for low blood pressure
90/60mmHg or lower
Physiological indicators - blood pressure, BMI, resting heart rate
State the correct classification for ideal blood pressure
Between 90/60mmHg – 120/90mmHg
Physiological indicators - blood pressure, BMI, resting heart rate
State the correct classification for pre-high blood pressure
Between 120/80mmHg – 140/90mmHg
Physiological indicators - blood pressure, BMI, resting heart rate
State the correct classification for high blood pressure
Above 140/90mmHg
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a high blood pressure could impact current physical health
Headaches – due to increased pressure in the brain.
Shortness of breath – due to the heart struggling to pump blood efficiently, resulting in a build-up of fluid in the lungs.
Physiological indicators - blood pressure, BMI, resting heart rate
Explain two ways that having a high blood pressure could impact future physical health.
Increased risk of heart attack – due to damaged arteries.
Increased risk of vascular dementia – due to damages to small blood vessels in the brain.
