To examine the effects of a single session of isometric physical exercise on postprandial triglyceridemia in sedentary male individuals with fasting triglycerides values150 mg/dl (NTG) or" 150 mg/dl (TG ALT).Twenty-seven individuals (10 NTG and 17 TG ALT), aged between 30-55 years were assessed in the study. Triglycerides were determined in the beginning, and at two, four and six hours after the oral ingestion of a solution with 50 g/m2 of fat in two occasions: at rest and after treadmill isometric exercise.Acute exercise did not affect the levels of postprandial triglycerides or the area under the curve (AUC) of triglycerides. However, the abnormal pattern of postprandial lipemia curve was associated with higher basal triglyceridemia with exercise (basal TG: 147 +/- 90 vs. 238 +/- 89 mg/dl, p = 0.02) and without exercise (basal TG: 168 +/- 93 vs. 265 +/- 140 mg/dl, p = 0.04). Analysis of the receiver operating characteristics (ROC) curves showed cut-off values for basal triglycerides with exercise of 166.5 mg/dl (sensitivity: 0.78; specificity: 0.72) and AUC of 0.772 [CI 95%: 0.588-0.955], and without exercise of 172 mg/dl (sensitivity: 0.78; specificity: 0.61) and AUC: 0.722 [CI 95%: 0.530-0.914].Acute exercise did not affect postprandial triglyceridemia in sedentary male individuals, and basal triglyceride levels are predictors of an abnormal response of postprandial triglycerides. |
