The acute effects of waterpipe smoking on lung function and exercise capacity in a pilot study of healthy participants

Abstract

Acute WTS appears to induce impairment in lung function and exercise capacity. Larger studies are warranted to further characterize the nature and extent of such impairment.

Investigation of Exclusive Narghile Smokers: Deficiency and Incapacity Measured by Spirometry and 6-Minute Walk Test

“…10,25,32,33 To the best of our knowledge, studies on maximal and submaximal aerobic capacities of ENS are rare: 10,25,33 two studies had evaluated the chronic effects of narghile smoke on passive animal smokers 33 and on human ENS, 10 and one evaluated its acute effects on human ENS. 25 Sulaiman 33 studied an experimental model of pregnant rats exposed to narghile smoke (daily for 10 min from days 2 to 18 of pregnancy) and examined the effect of smoking on locomotor activity of juvenile rats (ambulatory and stereotype behavior of offspring measured at the age of 30 d). He found that the total ambulatory activity and stereotype movements of exposed rats were 21% (P ϭ .08) and 26% (P ϭ .03) lower than those of matched controls, respectively, and that the decreased rates of ambulatory activity and stereotype movements in exposed rats were 28% (P ϭ .09) and 10-fold (P Ͻ .05) lower than those in non-exposed rats, respectively.…”

“…10,25,32,33 Characterizing such changes can add to a more comprehensive understanding of narghile smoking impact on critical physiological measures, and generated information can serve as a deterrent when counseling smokers against this seemingly harmless habit. 10,25,32,33 To the best of our knowledge, studies on maximal and submaximal aerobic capacities of ENS are rare: 10,25,33 two studies had evaluated the chronic effects of narghile smoke on passive animal smokers 33 and on human ENS, 10 and one evaluated its acute effects on human ENS. 25 Sulaiman 33 studied an experimental model of pregnant rats exposed to narghile smoke (daily for 10 min from days 2 to 18 of pregnancy) and examined the effect of smoking on locomotor activity of juvenile rats (ambulatory and stereotype behavior of offspring measured at the age of 30 d).…”

“…10,25,32,33 Adding to lung and heart function tests by including exercise capacity measures to test the impact of narghile smoke exposure is useful in that more subtle changes or effects that emerge only during stressful or dynamic conditions may then become detectable. 10,25,32,33 Characterizing such changes can add to a more comprehensive understanding of narghile smoking impact on critical physiological measures, and generated information can serve as a deterrent when counseling smokers against this seemingly harmless habit.…”

“…In addition, studies have demonstrated acute (immediate) effects of narghile smoke in the form of increased heart rate, breathing frequency, expired carbon monoxide, SBP, or DBP and a decline in lung function. [25][26][27][28][29][30][31] However, most of these studies have evaluated only changes in basic spirometric and/or cardiac measures at rest.…”
