Comparison of heart rate and heart rate recovery after six minute walk test in physically active and inactive smokers

Background: Smoking increases the risk of cardiovascular events and also impairs the function of heart and blood vessels. Physical activity plays a vital role in prevention of various diseases and produces lots of benefits.
Objectives: The objective of the present study was to compare heart rate and heart rate recovery after six minute walk test heart rate in active and inactive smoker Methods: In this study 30 participant were included out of this 15 were active smoker and 15 were inactive smoker aged 22-35 years. After initial screening and assessment of the participant level of physical activity was assessed by using GPAQ and subjects were diivided into active and inactive group; then six minute walk test (6MWT) was conducted in bioth groups. Resting heart rate, heart rate recovery upto 5 minutes and 6MWD were recorded in both the groups.
Results: The resting heart rate was significantly higher in inactive smoker as compared with active smoker (p<0.05). Heart rate after 6MWT was significantly higher in inactive smoker than active smoker (p<0.05). The heart rate recovery was delayed at the end of 1,2,3,4 and 5 minute of recovery in inactive smokers in comparison to active smokers (p<0.05). The distance walked by active smokers was significantly higher than inactive smokers (p<0.05).
Conclusion: The present study concluded that the resting heart rate is higher in inactive smoker as compared to active smoker. Heart rate recovery was delayed in inactive smokers. Physical activity plays a vital role in prevention of various diseases and could decrease the detrimental effect of smoking to some extent as compared to inactive smoker.

背景：吸烟加剧心血管事件的风险，并损害心脏及血管功能。体育锻炼在预防多种疾病中扮演着至关重要的角色，并带来众多益处。
目标：本研究的目的是比较活跃吸烟者和非活跃吸烟者在六分钟步行测试中的心率及其恢复情况。
方法：本研究纳入了30名参与者，其中15名为活跃吸烟者，另外15名为非活跃吸烟者，年龄在22至35岁之间。在初步筛选和评估参与者体能水平后，采用GPAQ进行评估，并将受试者分为活跃和非活跃两组；随后对两组进行六分钟步行测试（6MWT）。记录了两组的静息心率、5分钟内的心率恢复以及6MWD。
结果：与非活跃吸烟者相比，非活跃吸烟者的静息心率显著更高（p<0.05）。6MWT后的心率在非活跃吸烟者中显著高于活跃吸烟者（p<0.05）。与活跃吸烟者相比，非活跃吸烟者在恢复期的最后1、2、3、4和5分钟内心率恢复延迟（p<0.05）。活跃吸烟者行走的距离显著高于非活跃吸烟者（p<0.05）。
结论：本研究得出结论，非活跃吸烟者的静息心率高于活跃吸烟者。非活跃吸烟者的心率恢复延迟。体育锻炼在预防多种疾病中发挥着至关重要的作用，并且在一定程度上可以减轻吸烟的负面影响，相对于非活跃吸烟者而言。
