Which type of medication may have an effect on exercise by reducing heart rate and blood pressure?

Antibiotics
Beta-blockers
Anti-inflammatories
Diuretics

The correct answer is: Beta-blockers

Beta-blockers are a class of medications that primarily affect the cardiovascular system by blocking the action of certain hormones, particularly adrenaline (epinephrine), on beta receptors in the heart and blood vessels. This leads to a decrease in heart rate and blood pressure, making them effective in managing conditions such as hypertension, anxiety, and certain types of heart disease. When individuals taking beta-blockers engage in exercise, they may notice a reduced heart rate response to physical activity. This response can make it challenging to achieve target heart rates during aerobic workouts, potentially impacting the effectiveness of the exercise program for improving cardiovascular fitness. In contrast, antibiotics are used to treat infections and do not have a direct impact on heart rate or blood pressure. Anti-inflammatories primarily reduce inflammation and pain but do not significantly influence heart rate or blood pressure in the same way. Diuretics can help reduce blood pressure by promoting fluid loss but do not typically reduce heart rate. Therefore, beta-blockers are specifically known for altering cardiovascular responses during exercise.
