Abstract

Background: The aim of this study was to determine the effect of preconception endurance exercise training with voluntary exercise activity during pregnancy in mother mice on lipid profile in adult offsprings.

Materials and Methods: Twenty four C57BL/6 female mice were randomly divided into four subgroups: trained in preconception period and exercised during pregnancy (TE)(20.3±1.02g); trained in preconception periods but unexercised during pregnancy (TC)(21.58±0.4g); untrained in preconception periods but exercised during pregnancy (CE)(21.02±0.23g); untrained and unexercised (CC)(19.23±0.45g). Trained mice were subjected to a protocol of moderate endurance exercise training over a period of 4 weeks for 5 days before pregnancy. The fasting blood samples were collected from adult mice(8 weeks old) and serum levels of glucose and lipid profile were measured. Data were analyzed using two way ANOVA and Tukey’s post hoc test.

Results: The Glucose test results in offspring showed that there was a significant interaction between group and sex and group main effect (p<0.001) Glucose levels of male offspring were significantly lower in TC and TE groups. Results on LDL also showed that the sex main effect was significant (p<0.001), and LDL levels of male born to TE and TC dams lower than in female offspring.

Conclusion: Improving the mother's physical fitness by providing regular endurance training in the preconception period and maintaining it by exercise activty throughout pregnancy may have potential for eliciting positive changes in lipid profile of offspring, specially males.

Abstract
Background: The aim of this study was to investigate the effect of four weeks exercise prior preparation before Alzheimer's induction on the levels of nerve growth factor and beta amyloid in the hippocampus of Wistar male rats
Materials and Methods: 84 male Wistar rats (8 weeks old) with a weighing average of 20 ± 195 grams from Pasteur Institute of Iran were prepared, and rats were randomly divided to two exercise (4 weeks aerobic training on a treadmill with a gradient of 0 degrees, 5 days a week for 4 weeks) and rest groups. Then, the rats of each group were randomly assigned to 3 sub groups of 14 numbers, injection Aβ1-42, control, and non-injected. 48 hours after the last exercise session, injections into the hippocampus amyloid beta or Dimethyl sulfoxide were performed. Seven days after surgery, the rats of each group were randomly sacrificed or subjected to behavioral testing. To determine the levels of of nerve growth factor and beta amyloid Sampling was performed from the hippocampus and plasma of animals, a Morris water maze test was used for spatial memory test. Kolmogorov-Smirnov test (KS) and analysis of variance were used to analyze the data.
Results: The results of one-way analysis of variance showed that there was a significant difference between the levels of amylohyd of hippocampus and NGF in different groups. Also, the results of the probe test for spatial memory showed that the time spent on the target circle in the Aβ1-42 injection group was significantly lower than the other groups (p≤ 0.01). Also, the exercise and exercise + sham groups had a significantly better performance than control group.
Conclusion: It seems that performing physical activity before induction of Alzheimer's in rats is a kind of countermeasures and preeclampsia with physiological disorders and progression of the disease.
