#1
Which of the following is a risk factor for cardiovascular disease?
High blood pressure
ExplanationHigh blood pressure increases the workload on the heart and can damage arteries over time.
#2
What is the average resting heart rate for adults?
70-80 beats per minute
ExplanationThis range indicates a healthy heart rate at rest for most adults.
#3
What is VO2 max a measure of?
Cardiovascular endurance
ExplanationVO2 max measures the body's ability to transport and use oxygen during exercise, reflecting cardiovascular fitness.
#4
Which of the following exercises primarily targets cardiovascular health?
Running
ExplanationRunning is a highly effective aerobic exercise that strengthens the heart and lungs.
#5
Which lipid is commonly known as 'bad' cholesterol?
LDL
ExplanationLDL cholesterol contributes to plaque buildup in arteries, increasing the risk of heart disease.
#6
Which of the following is a symptom of a heart attack?
Chest pain or discomfort
ExplanationChest pain or discomfort is a classic symptom of a heart attack, often described as pressure, squeezing, or tightness.
#7
What is the recommended amount of moderate-intensity aerobic exercise per week for adults?
At least 60 minutes
ExplanationAdults should aim for at least 60 minutes of moderate-intensity aerobic exercise each week for optimal cardiovascular health.
#8
What is a common measure of aerobic exercise intensity?
METs (Metabolic equivalents)
ExplanationMETs quantify the energy expenditure of various activities, helping gauge the intensity of aerobic exercise.
#9
Which of the following is NOT a component of the DASH diet, often recommended for heart health?
High sodium intake
ExplanationThe DASH diet emphasizes reducing sodium intake to support heart health, making high sodium intake contradictory.
#10
What is the term for the narrowing of arteries due to plaque buildup?
Atherosclerosis
ExplanationAtherosclerosis is the gradual narrowing and hardening of arteries due to plaque buildup, which restricts blood flow.
#11

2,000 milligrams
ExplanationMost adults should aim to consume no more than 2,000 milligrams of sodium per day to maintain heart health.
#12
Which type of exercise is specifically beneficial for improving cardiovascular endurance?
High-intensity interval training (HIIT)
ExplanationHIIT involves alternating between short bursts of intense exercise and brief recovery periods, effectively improving cardiovascular endurance.
