What is the exercise response to acute cigarette smoking?

Acute smoking does not decrease blood pressure response to exercise; nicotine elevates blood pressure via sympathetic activation and peripheral vasoconstriction.

While coronary artery spasm risk correctly increases with smoking, blood pressure response to exercise also increases - not decreases - due to nicotine's vasoconstrictive and sympathomimetic effects.

Nicotine stimulates catecholamine release, which directly increases both resting and exercise heart rate. Simultaneously, smoking-induced endothelial damage and sympathetic activation promote coronary vasospasm, reducing myocardial oxygen supply during exercise. These combined effects significantly increase cardiovascular risk during physical activity following acute smoking.

Smoking increases coronary artery spasm risk through endothelial dysfunction and sympathetic activation; it does not decrease it, making this choice incorrect on both counts.
