Abstract
Exercise during pregnancy has beneficial effects on maternal and offspring’s health in humans and mice. The underlying mechanisms remain unclear. The aim of this study was to determine swimming exercise during pregnancy for 4 weeks effecting the body weight, corticosterone level and the lower bone morphology in offspring mice. Female mice (n:30) were divided into two groups: Exercise group (Ex) and control group (Co), each group contained (15 mice). Female mice mated with eight to ten-week-old male mice overnight. Blood and tissue samples were collected. Serum concentrations were measured by Eliza Kit and the histological methods of lower bone such as femoral and tibia limbs were also measured.

Ex group displayed a significantly higher of corticosterone serum concentration compared to Co group. Tibia limbs showed a clear development in Ex group as the femoral section of a single development of bone tissue cells with greater deposition of calcium phosphate within the bone tissue compared to the Co group. These results suggest that swimming exercise during pregnancy can result in lasting changes to the musculoskeletal system.
