METHODS: Three groups of rats (n = 7 in each group): sedentary pregnant rats (PS), exercised during regnancy (PE) and pregnant rats trained before and during pregnancy (PT) were compared. They were separated nto three subgroups regarding water temperature: 28ˇăC, 35ˇăC or 39ˇăC. Plasma triglycerides and glucose levels, eight gain during pregnancy and rectal temperature pre and post exercise (swim), as well as the offspring size and weight were analysed. RESULTS: Rectal temperature post exercise was lower than pre exercise at 28ˇăC and 35ˇăC, and higher at 39ˇăC. eight gain was lower at 39ˇăC for the PT group and at 35ˇăC for the PT and PE groups compared to the PS group. Plasma glucose, at 28ˇăC and 39ˇăC for PS and PE groups, was higher than those obtained at 35ˇăC, while triglycerides ere lower. For trained rats, plasma glucose and triglycerides were similar at all water temperatures. rained rats presented lower triglyceride values at 35ˇăC, and higher triglyceride values at 39ˇăC compared to PS roup. Glucose presented inverse results. None of the groups presented fetal reabsorption. However, in the PS group, the offspring presented lower weight gain at 28ˇăC than at 35ˇăC and 39ˇăC. CONCLUSIONS: These results suggest that pre-pregnancy physical training induces steady values of triglycerides and glucose during exercise at all water temperatures.
