A total of 9 articles were included in the final review based on the inclusion and exclusion criteria. These included articles assessed the effects of tobacco smoking on maximum values.RESULTS: Half of the articles reported a significant difference in maximum scores between smokers and nonsmokers, with smokers having a lower maximum . The other half of the articles did not identify significant differences between smokers and nonsmokers. One study found a significant difference in maximum in only one age group (ie, 20–29 y), but not any of the other age groups.CONCLUSIONS: More research is needed on the effects of smoking on maximum to better understand any relationships or causations.
