Abstract

|
|
This study aimed to verify habitual smoking effects on cardiopulmonary function in taekwondo athletes. Subjects were university taekwondo athletes aged 20?24 years in nonsmoker (n= 9) and smoker (n= 6) groups. Subjects underwent an exercise examination for their ventilation threshold, minute ventilation, oxygen uptake, maximum volume of minute oxygen consumption, heart rate, and oxygen pulse during exercise and 1, 3, and 5 min after maximum exercise. The time of reaching the ventilation threshold was significantly higher in nonsmokers than in smokers. Heart rate during recovery after maximum exercise was significantly lower in nonsmokers for 1 and 3 min. Nonsmokers had significantly higher time for reaching the ventilation threshold and heart rate recovery at 1 and 3 min after exercise. The higher timing of accumulation fatigue in ventilation amount and faster recovery after exercise are useful in continuous exercise and improving athletic performance. Thus, athletes should stop smoking as soon as possible to improve their aerobic physical fitness and athletic performance.
