Abstract:
This study was aimed at investigating the effects of selected Aerobic exercises on improving
cardiovascular endurance female student athletes at Ansho secondary and preparatory school.
To achieve the raised objective, the researcher selected 48 female athletes purposively from
Ansho Secondary and Preparatory school grade 9th
-12th students. They were assigned in to
experimental and control group purposively. The proper experimental data was collected for
three consecutive months through careful follow up of the researcher. Control group female
student athletes did not participate in any aerobic exercise. The data was recorded from
aerobic exercise of female student athletes starting from morning twelve o’clock up to one and
half o’clock for three days in a week. The data was properly analyzed using t-test, ANOVA,
mean analysis and graphical statistical approaches. As the step test record has shown, on
average their result has fallen under excellent level according to international norm (<129).
Moreover, their mean resting heart rate and exercise heart rate has shown steady declination
(148.25 to 122). Before starting the Step Test, their average distance covered was 2621.167m
and soon after they started, their average their distance grown up to2868.97m. The t-test
analysis has confirmed that there were significant mean cardiovascular endurance difference
between control and experimental group female student athlete on both twelve minute run and
step test. The average cardiovascular endurance also steadily increased from pretest to posttest.
The ANOVA (Analysis of Variance Test) also confirmed insignificant variation of
cardiovascular endurance between both groups of students before starting aerobic exercise.
However, soon after they started their aerobic exercise the test has shown significant variation
between the groups. Having deep statistical analysis, it was concluded that aerobic exercise
had significant effect on cardio vascular endurance of the female student athletes in
experimental group. Thus, school principals, Woreda sport and youth affairs department
office and other stock holders should have to participate in motivating female students for
aerobic exercise and they should also facilitate materials for schools and for the society as
whole.
