Effects of single sessions of low-intensity continuous and moderate-intensity intermittent exercise on blood lipids in the same endurance runners

摘要: Summary The factors responsible for the acute effects of exercise on blood lipids are not well known, and there have been few studies comparing different kinds in same population. concentration was evaluated this study at end post-24 h two 14 km/90 min single sessions: continuous (CE) 44.5 ± 5.6% VO 2max intermittent (IE) 39–72% , subjects with high levels aerobic training. Fourteen male athletes (endurance runners) took part each completed a 24 h dietary record. O 2 uptake CO production were recorded, lactate measured. results showed that triacylglycerols modified by any kind exercise. Total cholesterol increased both exercises: 7.04% CE ( p  = 0.001). High-density lipoprotein IE: 11.38%  = 0.03) low-density only CE: 7.45%  = 0.006). increase negatively correlated fitness indicators (heart rate %HRmax threshold), positively associated energy expenditure. For IE, correlated, respiratory exchange ratio lipid increase. We conclude trained athletes, 14 km run 90 min induced changes profile if done continuously or intermittently, extent these increases influenced fitness.
