Regular physical activity is beneficial at all ages. Physical exercise has many positive effects in the postpartum period as well, as it reduces anxiety, improves mood, optimizes body weight and enhances fitness. During our research, we examined the changes in the sporting habits of mothers with small children compared to the pre-natal state, with a special emphasis on the time spent at home and the time of returning to work concerning children of ages of six months and up to three years, respectively. One-third of the respondents did not play any sports before giving birth and a further one-third does not have time for that. 17.1% of the mothers returning to work participate in some sort of sporting activities at least once a week. In addition to maternity duties, a significant proportion of women do not have time for themselves. Further research would be necessary to explore possible solutions in this matter.
