Effects of Tobacco Consumption on Aerobic Fitness in Indian Adult Men
Background and Aim: Smokeless tobacco products like khaini, guthakha, betel quid, zarda are very commonly consumed by men and women of all age group followed by smoking of bidi, cigarette and hookah. Tobacco consumption is associated with poor cardiorespiratory, gastrointestinal and overall health. Compromised physical fitness is seen in tobacco consumers and severity depends on type of product and duration of use. Aerobic or cardiorespiratory fitness is compromised in tobacco consumers. This study was planned to check the effect of tobacco consumption on aerobic fitness of Indian adult men of 18 to 60 years of age group. Methods: Participants for this study were recruited from Pramukhswami Medical College and its affiliated institutes after obtaining permission from the Institutional Ethics Committee (IEC). A total 74 adult men of 18-60 years’ age groups were enrolled for the present study after their voluntary consent. A total 24 participants who consume tobacco were placed in study group and a total 50 participants who were not consuming tobacco products were placed control group. All participants were apparently healthy at the time of Treadmill exercise stress test following Bruce protocol. Predicted VO2 max (PVO2 max) was calculated on the basis of total exercise time in minutes and seconds on Treadmill machine as per Bruce’s formula of calculating indirect maximal oxygen consumption. Results: PVO2 max values obtained by Treadmill exercise test following Bruce protocol in study group was 29.16 ± 8.88 ml/kg/min while control group was 36.47 ± 9.7. A statistically significant reduction in aerobic fitness was seen in study group as compared to control group. Conclusion: Aerobic fitness was significantly less in tobacco consumer Indian adult men of 18-60 years’ age group as compared to who do not consume tobacco.
