Heavy resistance training and straining type exercises:

Decrease blood pressure dramatically
Increases the risk for individuals with existing hypertension or CAD
Increases blood pressure dramatically because it compresses peripheral arterioles
Both b and c

Correct Answer

A. Both b and c

Explanation

Both heavy resistance training and straining type exercises can increase blood pressure dramatically. Heavy resistance training puts strain on the cardiovascular system, leading to an increase in blood pressure. Additionally, these exercises can compress peripheral arterioles, further contributing to the increase in blood pressure. For individuals with existing hypertension or coronary artery disease (CAD), this can pose a greater risk as it can exacerbate their condition. Therefore, the correct answer is both b and c.

After a bout of sustained light to moderate intensity exercise:

Systolic blood pressure increases
Systolic blood pressure permanently drops
Systolic blood pressure temporarily drops below pre exercise levels for up to 12 hours
Diastolic blood pressure temporarily drops below pre exercise levels for up to 12 hours.

Correct Answer

A. Systolic blood pressure temporarily drops below pre exercise levels for up to 12 hours

Explanation

After a bout of sustained light to moderate intensity exercise, the systolic blood pressure temporarily drops below pre-exercise levels for up to 12 hours. This is because during exercise, the heart pumps more blood to meet the increased demand for oxygen and nutrients in the muscles. As a result, the blood vessels dilate, allowing for increased blood flow and lowering the resistance to blood flow. After exercise, it takes some time for the blood vessels to return to their normal state, causing a temporary drop in systolic blood pressure. This drop usually lasts for up to 12 hours before returning to pre-exercise levels.

Blood pressure is equal to:

Cardiac output divided by heart rate
Cardiac output multiplied by stroke volume
Cardiac output multiplied by total peripheral resistance
Blood pressure divided by cardiac output

Correct Answer

A. Cardiac output multiplied by total peripheral resistance

Explanation

Blood pressure is determined by the amount of blood pumped by the heart (cardiac output) and the resistance encountered by the blood vessels (total peripheral resistance). When the heart pumps more blood and the resistance in the blood vessels is higher, the blood pressure increases. Therefore, the correct answer is "cardiac output multiplied by total peripheral resistance" because both factors contribute to determining blood pressure.

Rate pressure product and oxygen uptake can be determined by:

Diastolic and systolic blood pressure
Systolic blood pressure and stroke volume
Diastolic blood pressure and heart rate
Systolic blood pressure and heart rate

Correct Answer

A. Systolic blood pressure and heart rate

Explanation

The rate pressure product is a measure of the oxygen demand of the heart and can be determined by multiplying the systolic blood pressure and heart rate. This is because the systolic blood pressure represents the force exerted on the walls of the arteries during the contraction of the heart, while the heart rate represents the number of times the heart beats per minute. Therefore, multiplying these two values provides an estimation of the oxygen demand of the heart.

What are the three mechanical factors that determine myocardial oxygen uptake?

Tension development within the myocardium, stroke volume, and blood pressure
Blood pressure, tension development, and heart rate
Myocardial contractility, heart rate, and blood pressure
Tension development within the myocardium, myocardial contractility, and heart rate

Correct Answer

A. Tension development within the myocardium, myocardial contractility, and heart rate

Explanation

The three mechanical factors that determine myocardial oxygen uptake are tension development within the myocardium, myocardial contractility, and heart rate. Tension development within the myocardium refers to the force generated by the contraction of the heart muscle. Myocardial contractility refers to the ability of the heart muscle to contract and pump blood effectively. Heart rate is the number of times the heart beats per minute. These factors collectively determine the amount of oxygen that the myocardium requires to function properly.
