Effect of Interval Training on Hematocrit and Hemoglobin Levels of Sprinters

Abstract

Background & Objective – This study aims to investigate the effects of interval training on the blood hemoglobin level and hematocrit (Hct) of sprinters. Method – This experimental research used a repeated measure ANOVA design. For the study, 40 male sprinters were selected using a purposive sampling technique and they were further randomly assigned to two groups named the control group and the experimental. The experimental group received interval training 3 times a week for a duration of 6 weeks. To examine the effect of interval training on hemoglobin levels and hematocrit blood samples were taken at three different levels - before training (pre-test), after 2 weeks of training (mid-test), and after completion of training (post-test), Hemocue Hb 201 devices were used to measure hemoglobin levels. The result of the study was analyzed using repeated measures-ANOVA. The findings of the study indicated that average hemoglobin and hematocrit levels significantly increased among the experimental group. It can be concluded that 6 weeks of interval training can significantly raise increase hemoglobin levels and hematocrit among sprinters.
