Smoking has a detrimental impact on athletic performance by affecting lung function, cardiovascular health, and endurance. It decreases oxygen availability in the body and hinders the ability of the lungs to transfer oxygen to the bloodstream efficiently. Consequently, this leads to decreased stamina and endurance during physical activities. Moreover, smoking increases the risk of injuries and prolonged recovery times due to its negative effects on circulation and inflammation. For athletes aiming for peak performance, quitting smoking is crucial for enhancing fitness, endurance, and overall health.
