This study was carried out to investigate the measurement level of
maximum volume of oxygen (VO2 max) rate for a continued period
of four weeks (one month) amongst randomly selected Bo
Commercial Junior Secondary School (JSS I, II and III) pupils in the
Bo Municipality, Sierra Leone. The significance of the study is to
measure and compare the VO2 max of both boys and girls at the three
different strata i.e. JSS I, II & III using cooper-12-minutes-run test.
A total of thirty (30) pupils (15 boys and 15 girls) were randomly
selected at the three levels (JSS I, II & III), with age ranging from ten
to seventeen (10-17) years. The Pearson Product Moment
Correlation (PPMC) Coefficient, Dependent and Independent t-tests
were used to compare the results of the study. The results were tested
at (p ≤ 0.05) level of significance. Analysis of results from weeks
one, two, three and four shows both significant and insignificant
differences between the measured values of VO2 max rate of boys
and that of girls (JSS I, II & III) at the beginning and at the end of the
exercise which is recorded as r values [(i.e. r values ranging from r =
0.0000 to r = 0.7442) when compared with the c value (i.e. c value =
0.8783)] as shown in tables I, II, III and IV; and as t values [(i.e. t
values ranging from t = 10.249 to t = 3.728) when compared with the
dependent and independent c values (c = 2.776 and c-value = 2.306)]
as shown in tables V, VI, VII, VIII, IX, X, XI and XII. Conclusively
therefore, the major findings in this study shows that pupils (boys
and girls) were experiencing quick fatigue at the beginning of the
exercise which affected the low rate of their VO2 max calculation
greatly but they had to overcome the fatigue as the session continued
into the subsequent weeks thereby improving their rate. In
recommendation, the most effective approach to improving VO2 max
rate in pupils is by applying the endurance high intensity interval
training (HIIT) during practical session in schools.
