swimming exercise protocol and care methods for pregnant rats

The Developmental Origins of Health and Disease (DOHaD) concept emerged over the last two decades, which has shown that environmental influences during early development affect the risk of later pathophysiological processes associated with chronic non-communicable disease (NCD), especially diabetes, cardiovascular disease, and some types of cancer1. During the most plastic phase of fetal development, where offspring are exposed to the intrauterine environment, the gene and environment interaction and uteroplacental perfusion are crucial factors of fetal reprogramming2. Previous studies have predominantly utilized animal models to investigate the detrimental effects, such as maternal undernutrition, overnutrition, or obesity during pregnancy, and prenatal exposure to chemicals or hypoxia, on fetal development and long-term phenotypic effects in the offspring3. This produced low birth weight and later growth and produced adverse effects on offspring, including elevated blood pressure, dyslipidemia, and insulin resistance4. Since the rate of overweight and obesity is rapidly increasing among women of reproductive age, establishing effective interventions to prevent the intergenerational transmission of these deleterious maternal disorders is urgently needed, which has an important impact on population health5,6.
Exercise has long been recognized as an important preventive therapeutic for type 2 diabetes, hypertension, and several other diseases7. Exercise during pregnancy has beneficial effects for the mother and confers beneficial effects on offspring, thus reducing the maternal transmission of disease to offspring8. Several years of research have demonstrated exercise&#39;s safety and profound benefits, including substantial reductions in common pregnancy conditions such as gestational diabetes mellitus9,10. Regarding maternal and fetal safety, conducting exercise training and post-nursing protocols is challenging.
David11 et al. described animal exercise models applicable to cardiovascular health research. The three commonly used exercise models, voluntary wheel running, motorized treadmills, and swimming, have advantages and disadvantages. The voluntary wheel running closely mimics the locomotor behavior of rats, enabling them to move according to their circadian rhythm. However, this sort of exercise needs more precise regulation of intensity and duration. The motorized treadmill can control exercise intensity, volume, and duration, but sometimes it needs electric stimulation, which may trigger physical and psychological stress in the animals. Swimming is widely used in rodent studies due to the inherent swimming ability of rats, which can also avoid electric stimulation or mechanical damage to their feet and tails12. In studies on prenatal exercise models13,14, swimming is a commonly used exercise modality. As pregnancy progresses and the abdomen of the rat swells, treadmill and wheel running exercises may cause repeated contact of the abdomen with hard surfaces. In contrast, the water environment in swimming provides buoyancy, reducing the risk of exercise-related injuries for pregnant animals.
This protocol presents the rat breeding methods, how to perform the swimming training during pregnancy, and the post-breeding nursing protocols for pregnant rats after training. This pregnant swimming training model can be applied to a wide range of rat and mouse species, which may thus provide a useful rodent model for future investigation using animal-based models to study the mechanisms regulating the beneficial effects of maternal exercise on offspring health and the benefits of exercise across generations.

Our research delineates rat-breeding methods. Prenatal swimming training produces, and the post-breeding nursing protocols for rats, which will be of good help to the researchers of exercise physiology and the perinatal biology. As pregnancy progresses and the abdomen of the rat swells, treatment and the regularly exercises may cause repeated contact of the abdomen with hard surfaces.In contrast, the water environment in swimming exercise protocol provides buoyancy, reducing the risk of exercise-related injuries for pregnant animals. Maternal obesity can lead to an increase in incidents of cardiovascular and metabolic diseases in offspring. In the future, when we apply this swimming exercise protocol to a high-fat diet, induce the obese, pregnant mice to explore the apt in a tic mag design.and find a new way to curb the intergenerational inheritance of obesity-related diseases.
