The first hypothesis is that the HIIT, implemented during pregnancy and after childbirth, as a stronger exercise stimulus, will have a better impact on selected biological and psychological parameters of mothers, as well as on selected health parameters of their children, compared to the MICT (moderate intensity continuous training). Therefore, it promises better preventive effects on pregnancy complications and ailments as well as non-communicable diseases occurring in these populations.
