The aim of this study is to determine the effect of rafting and paragliding exercises by sedentary males on serum lipids.17 male rafters and 10 male paragliders volunteers (non-smoker, no known history of cardiovascular disease, body mass index <25 kg/m, and no intake of prescription medications) participated in the study. Participants had blood samples taken a day before and after rafting and paragliding practices. Data were analyzed by Wilcoxon and Mann-Whitney U tests.Significant decreases occurred for the low-density lipoprotein (LDL)/very low-density lipoprotein (VLDL) ratio in the rafting group after the exercise; though, there was no significant difference in serum lipids parameters of the paraglide group after the exercise.While acute rafting and paragliding exercises have similar effects on TG and HDL, effect on LDL/VLDL ratio is different.
