3.3 Test the correlation of pulmonary
vital capacity and hemoglobin level
with maximum aerobic capacity
Based on Figure 1c compared to the average score,
the sample in the average class was 7 (30.44%) and
below the average class was 8 samples (34.78%)
while the sample in above the average class was 8
samples (34.78%). The analysis between Figure 1c
and Table 1 showed that there were 8 athletes who
had enough VO2Max and 15 athletes who had less
VO2Max than the total sample of athlete club of
Muhardi Football Academy as many as 23 athletes.
Table 4: Standard Value of VO2Max of Athlete (Tim
Seleksi Prima).
The relationship between the vital capacity of the
lungs (X1) and the haemoglobin (X2) with the
maximum aerobic capacity (Y) was expressed by the
regression equation Ŷ = 13.3 + 0.397X1 + 0.337X2
and shown by the double correlation coefficient ry1-
2 = 0.60. The result of significance test of double
correlation coefficient showed that F-count = 5.625
was bigger than F-table = 3.49 which meant double
correlation coefficient ry1-2 = 0.60 was significant
and positive. Although both variables have a positive
and significant relationship, all athletes do not have a
good maximal aerobic capacity or more. VO2Max is
probably the single most important factor
determining success in an aerobic endurance sport;
However, within the same person, peak oxygen
transport is specific to a given type of activity such as
the position of the athlete (Hoff and Helgerud, 2004).
Thus, the concurrent endurance training program
together with regular football training is needed to
result in considerable improvement of the players ’
physical capacity and so may be successfully
introduced to elite football players (Helgerud, et al.,
2011). The coefficient of determination of
haemoglobin level and vital capacity of the lungs with
maximum aerobic capacity was (ry1-2) = 0.3600.
This meant that 36% of maximal aerobic capacity was
determined by the vital capacity of the lungs (X1) and
haemoglobin (X2) levels.
4 CONCLUSIONS
Maintenance of vital capacity of the lungs and
haemoglobin levels as a determinant factor can
provide positive implications for the maximum
aerobic capacity of progressive soccer athletes. One
way to maintain the vital capacity of the lungs and
haemoglobin levels is through intensive exercise.
Based on the results of data analysis above showed
that there was a relationship between the vital
capacity of the lungs and haemoglobin level with a
maximum aerobic capacity in football athletes of
Muhardi Football Academy (MFA) of 36%. In
addition, there are 23 athletes lacking good vital lung
capacity, 23 athletes have normal haemoglobin level
and 8 athletes have maximum aerobic capacity in
sufficient category and 15 athletes in the less
category. Thus, the variables studied should be of
concern to athletes and other relevant parties,
especially variables of the vital capacity of the lungs
to increase the maximum aerobic capacity of the
athlete. Further research needs to be done because
there are other factors, such as stroke volume, cardiac
output, pulse rate, and so on which has implications
of 64% to maximum aerobic capacity of athletes.
