Intravascular Hemolysis in Aerobic Dancing: The Role of Floor Surface and Type of Routine

Abstract

In brief: The effect of aerobic dancing on intravascular hemolysis was studied in 65 healthy women (aged 18 to 50 years) who were assigned to one of four groups according to the type of routine performed and the hardness of the floor surface. All subjects participated in a 60-minute dance session; a subgroup participated in five successive 60-minute sessions with one hour of rest between sessions. Blood was tested for both groups before and after exercise; urine was tested similarly for the subgroup only. The findings indicated that intravascular hemolysis occurred and that it was influenced by the type of routine, hardness of the surface, and duration of dancing. However, the degree of hemolysis was small and unlikely to contribute to the development of anemia.
