Background: It is well documented that cigarette smoking has negative impacts on body health, as well as social health, economy, culture, etc. Nowadays, there is a large body of evidence that smoking is the cause of numerous life-threatening diseases like cardiovascular and pulmonary diseases along with different kinds of cancer. The aim of this study was to compare the physical fitness of smokers and non smokers.

Methods: This cross-sectional study was conducted on 64 non-sportsmen (34 non-smokers and 30 smokers) aging 19–27 years. Both groups were matched for age, weight, height and body mass index (BMI). The smokers used cigarettes at least 5 cigarettes a day for 2 years. None of them had a musculoskeletal disease. We used a questionnaire and physical fitness tests for data gathering. The tests were used to measure muscle strength, endurance, speed, agility and flexibility in both groups.

Findings: The muscle strength was significantly different in smokers and non-smokers (P = 0.012). Moreover, smokers had less agility (P = 0.004) and speed (P = 0.008) than non-smokers. However, although smokers were weaker than non- smokers, the differences in muscle endurance (P = 0.066) and flexibility (P = 0.095) were not the statistically significant.

Conclusion: According to these results, the smokers were less powerful than nonsmokers. In addition, physical activity skills in young smokers were decreased. Therefore, smoking will cause a gradual loss of physical strength and active personal and social power.
