Studying the Effect of a Period of Reduced Training Load (Tapering) on Blood Indices of Female Karatekas

Abstract

Objective and background: In addition to being a recreational and invigorating activity, sports activities are considered an effective means of maintaining physical health and strength. The overall aim of the present study was to study the effect of a period of reduced training load on some blood indices (blood cells and hemoglobin) of female karatekas. Methods: The population consisted of 30 karatekas who had 5 years of sports experience, 14 of whom were randomly selected and divided into two control and experimental groups. 8 subjects were placed in the control group (regular sports activity), 8 subjects in the first experimental group (increasing resistance activity on the ergometer), 8 subjects in the second experimental group (increasing speed activity on the ergometer), and 8 subjects in the third experimental group (increasing power activity on the ergometer). The researcher took three milliliters of blood from the brachial vein from all subjects at the beginning and end of the training period before and after performing the Bruce maximum test on the ergometer, and the collected blood was transferred to the laboratory for analysis. Finally, the analysis of covariance test was used to compare the means in the four groups.
