the impact of rope jump exercise training on hemolytic anemia parameters in obese adolescent boys

Background: one of the theories about hemolytic anemia concerns foot-strike on the ground. rope jump exercise training (rjet) is performed with high foot-strike repetitions on the ground. objectives: this paper aimed to study the possible effect of rjet on hematological parameters involved in hemolysis. methods: twenty obese adolescent boys with a mean age of 13.40 ± 1.09 years were allocated into two equal groups of control and rjet (n = 10 each). the rjet group performed simple rope jumping for eight weeks (three days a week). blood samples were collected before and after the protocol. independent t-test and mann-whitney u test were used for data analysis. results: our findings showed no significant inter-group differences for erythrocyte, platelet, and leukocyte parameters. however, given the effect of time, a significant reduction was observed in monocyte count in the rjet group. in contrast, eosinophil count significantly increased after rjet. conclusions: according to the results, foot striking induced by rjet had no adverse effect on hemolytic anemia in obese adolescent boys.
