Investigat？on of the Factors Related to Change in Blood Lactate Level After Exercse in Healthy Male Cigarette Smokers: A Pilot Study

Purpose: The aim of our study was to investigate the factors related to change in blood lactate level after exercise in young healthy male smokers. Material and Method: Fourteen voluntary male smokers (mean age=21.29±8.10 year, cigarette smoking intensity=4.94±3.50 packXyear) were included in the study. The demographic features of the participants were recorded. Squat endurance and quadriceps muscle strength (J-tech dynamometer) were measured. The level of physical activity was questioned using the "International Physical Activity Questionnaire-Short Form". Lactate levels (Accutrend？ Plus) were determined with blood samples taken before and after "High-Intensity Interval Training" lasting 20 minutes with 75-85% of maximum heart rate. The data were analyzed with the SPSS 21.0 statistical program. Relations between variables were evaluated by Spearman correlation analysis. The level of significance was determined as p <0.05. Results: At the end of the training, when the relationship between the amount of change in blood lactate level with smoking intensity, physical activity level, quadriceps muscle strength and squat endurance is examined; it was found to be negatively correlated (p=0.042, r=-0.548) only with squat endurance. Conclusion: According to the results of our study, the increase in fatigue after high-intensity interval training in healthy young men who smoked was associated with endurance but not with the intensity of the person's smoking, physical activity level, and muscle strength. Further studies are needed in which fatigue markers examined in a large population after different intensity training sessions
