Long-term force of the blood against artery walls is abnormally high
Hypertension (high blood pressure)
Blood pressure is determined by both the _ and the _
- The more blood heart pumps and the narrower arteries, the higher the blood pressure
- amount of blood the heart pumps
- amount of resistance to blood flow in arteries
Hypertension (high blood pressure):
When blood pressure is too high
- Higher pressure puts extra _
- Over time, increases risk of heart disease, stroke, kidney failure
force on heart & vessels
Hypertension (high blood pressure):
When blood pressure is too high
- Negative cycle
** short answer
- If BP is too high, artery wall muscles will respond by pushing back harder
- Artery walls get thicker
- Less space for blood flow
- Then makes BP even higher
Hypertension (high blood pressure):
Risk factors
- Lack of physical activity
- Smoking, alcohol consumption
- Family history
- Too much salt
- Older age
Hypertension (high blood pressure):
Systolic Blood pressure =
> /= 130 mmHg
Hypertension (high blood pressure):
Diastolic Blood pressure =
> /= 80 mmHg
Blood pressure measurements fall into 4 general categories
- Normal BP
- Elevated BP
- Stage 1 hypertension
- Stage 2 hypertension
Blood pressure measurements:
Below 120/80 mmHg
Normal BP
Blood pressure measurements:
Systolic pressure ranging from 120-129 mmHg and a diastolic pressure ranging from 80-89 mmHg
Elevated BP
Blood pressure measurements:
Systolic pressure ranging from 130-139 mmHg or a diastolic pressure ranging from 80-89 mmHg
Stage 1 hypertension
Blood pressure measurements:
Systolic pressure of 140 mmHg or higher or a diastolic pressure of 90 mmHg or higher
Stage 2 hypertension
Effects of Ex response
BP increases
Effects of Ex response:
Persons who have hypertension
- SBP could be extremely high (sometimes even >/= 250 mmHg)
- DBP remains constant, sometimes decreases
Effects of Ex response:
Persons who have hypertension
- SBP could be extremely high (sometimes even >/= 250 mmHg)
– Several factors that affect BP, including blood volume, stroke volume, and heart rate
— To meet muscles’ increased oxygen demand, all these factors _
increase during exercise
- As a result, SBP rises
Effects of Ex response:
Persons who have hypertension
- DBP remains constant, sometimes decreases
– To create more space for the increased blood flow during exercise, arteries _
dilate so DBP remains the same
Effect of Ex training:
Aerobic Ex training _
reduces BP
Effect of Ex training:
Aerobic Ex training reduces BP
- _ reduction in resting BP
– Regular physical activity makes your heart stronger
— A stronger heart can pump more blood with less effort
—- If your heart can work less to pump, the force on your arteries decreases, lowering your BP
5-10 mmHg
Ex testing:
Consult with doctor and obtain _ prior to physical activity
- Self-guided method & pre-screening (CVD risk factor classification)
clearance
Ex testing:
Stop Ex testing when _
- senior fitness test
SBP >/= 250 and/or DBP >/= 150 mm Hg
Ex programming:
- Benefits are greater when _
lose weight
Ex programming:
- It is advisable to accumulate more than _
150 min/week
Ex programming:
- If only hypertension, with no other conditions: follow _
- If combined with other conditions: use _
- healthy individual guideline
- chronic disease individual guideline
Special considerations for hypertension:
- Meet physician, self-guided methods
- watch out the adverse effects of medicine
- Ex Rx should focus on increasing caloric expenditure and reducing caloric intake
- _ is recommended
Moderate physical activity
Chronic conditions associated with physical inactivity:
- “Bad” - “Fatty acid” - “Blood”
Dyslipidemia
Chronic conditions associated with physical inactivity:
Hypertension & Dyslipidemia
- Frequently occur_ due to physical inactivity
- CVD risk factors
- 30% US population with _
- Nearly half of adults in US (180 million, or 45%) have _
- together
- Dyslipidemia
- hypertension
Chronic conditions associated with physical inactivity:
Abnormal blood lipid and lipoprotein concentration
Dyslipidemia
Chronic conditions associated with physical inactivity: Dyslipidemia
Abnormal blood lipid and lipoprotein concentration
- Low-density lipoprotein (LDL) cholesterol _ or,
- High-density lipoprotein (HDL) cholesterol _
- increases
- decreases
Chronic conditions associated with physical inactivity:
- Major cause of
– CVD
– Heart attacks
– Stroke
Dyslipidemia
Dyslipidemia:
Soluble proteins that combine with and transport fat or other lipids in blood
lipoprotein
- In All cells of the body
- We need it to make hormones, V-D, and substance that helps digest food
- Your body makes all the cholesterol it needs
Cholesterol
Dyslipidemia - Cholesterol:
_ is bad because it becomes part of plaque, the stuff that can clog arteries and make heart attacks and strokes more likely.
LDL
Dyslipidemia - Cholesterol:
_ cholesterol is “good” cholesterol
- Think of it as the “healthy” cholesterol, so higher levels are better.
- Experts believe HDL acts as a scavenger, carrying LDL cholesterol away from the arteries and back to the liver, then broken down and out of the body.
HDL
Effects of Ex training:
Benefits on blood lipids
- 5%-10% _ in LDL-C
decrease
Effects of Ex training:
Benefits on blood lipids
- 5%-10% _ in HDL-C
increase
Statistical procedure for combining data from multiple studies, meta-analysis can be used to identify the common effect/finding among studies
Meta-analysis
