Abstract:
Motor Fitness is a readiness or preparedness with special regard for big muscle activity
without undue fatigue. The students of sport science need motor fitness as they are involved in
various vigorous practical activities during their practical class. The purpose of this study was
to investigate the ef ect of 12 week planned aerobic exercise on selected motor fitness
variables (reaction time, flexibility and balance) of male sport science students of Debre
Birhan University. Sixty (60) under graduate male sport science students free from any health
problems, with age group between 19 – 25 years were selected by random sampling technique
from Debre Birhan University sport science department in all batches, out of total population
(111) only 60subjects were able to complete the study and purposive sampling was used to
select the sex and department of subjects in relation with the study site. The selected subjects
were divided into 2 groups i.e. control and experimental groups randomly, each group
consisting of 30 students. The experimental group underwent 12 weeks planned aerobic
exercise program, three days per week and the duration was 1:00hour while, the control
group continued with their regular activity. Pre-test, during training test and post tests were
conducted on the selected motor fitness variables such as sit and reach test, stork balance
stand test and ruler drop test, each subject was tested at the same time of day. The data
collected from subjects were analyzed by SPSS version 20.0 and the comparison of mean
value results was carried out by paired sample t-test. The level of significance was p<0.05. The finding of the present study showed significance (P0.05) improvement in experimental
group than control group of the study as sit and reach test (Mean dif erence 11.534), ruler
drop test (Mean dif erence .0468) and stand balance stork test (Mean dif erence 12.234) for
experimental group. However, in the control group there was not significance dif erence or
improvement seen in all selected motor fitness variables. So this study concluded that 12week
aerobic exercise have a positive ef ect on improving these selected motor fitness variables of
sport science students of DBU
