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.
