抽菸對非最大運動後的恢復能力之影響

The Effect of Smoking on the Recuperation after Exercise

Abstracts


目的:本研究在探討抽菸對人體非最大運動後的恢復能力之影響。方法:以59位帄均21歲的空軍官校健康男生為自願受測者(抽菸組29位、不抽菸組30位),均接受一氧化碳、血壓、躺姿安靜心跳、血氧飽和度、3000公尺跑步、3分鐘登階測驗以預估最大攝氧量值,並記錄登階結束後前20秒內的安靜心跳率,以求得運動後的心跳恢復率。經以獨立樣本t-test檢定考驗兩組間的各項差異。結果:抽菸組的一氧化碳值、躺姿安靜心跳率明顯比較高、血氧飽和度比較低、運動後心跳恢復能力亦比較差。結論:抽菸雖未必會影響運動成績,但實際上,抽菸使體內供氧能力受損,會延遲運動後的恢復能力。建議長跑或間歇訓練者,宜先戒菸以優先改善體內供氧能力,方能使訓練事半功倍。

Purpose: The purpose of this studing was to examine the effect of smoking on the recuperation after exercise. Methods: The focus was on 59 male students (29 smokers and 30 non-smokers) who were 21 years old and studing at The Air Force Academy. All of the subjects took the physical characteristics measurement of CO value, blood pressure (BP), resting heat rate (HRrest), blood oxygen saturation (SpO2), and cardiorespiratory endurance test of 3-minute step test for estimation of VO(subscript 2max), 3000-meter run, and checked the gradient of the earliest 20 seconds heart rate after 3-min step test (HR%), to estimate the recuperation of heart rate after exercise. Comparison of physical characteristics and HR% between the smoking group and non-smoking group with t-test. Results: Both CO value and HRrest of the smoking group were significantly higher than non-smoking group, but SpO2 was lower. The recuperation of HR% after exercise of smoking group was significantly worse than non-smoking group. Conclusion: Whether or not smoking should not change the results of athletic performance, because the most important factors to influence the result of exercise performance were training intensity and training frequency. But smoking would delay the recuperation of supply oxygen after exercise definitely. This result was suggested that those who want to promote cardiorespiratory endurance, should give up the habit of smoking first, especially for long distance training and interval training runner.
