measure of fitness in general and endurance capacity in particular.
However, in recent years evidence has accumulated suggesting that VO2 max
values provide only limited information regarding endurance capacity.
This study set out to investigate the influence of training on the
maximum oxygen uptake and endurance capacity of male and female subjects. The investigation consisted of three studies. The first described
the relationship between VO2 max
correlation between VO2 max and Z
individuals within the group with
differently. The second study examined the influence of short term training on
VO2 max and endurance capacity. The increase in VO2 max was small
(7%) when contrasted with the large improvement in endurance capacity
(478%). The above two studies both indicated that VO2 max alone does not
determine endurance capacity. The third study therefore set out to
examine which factors influence changes in VO2 max and endurance capacity
after a period of endurance training. By adopting a single-leg exercise
model (Davies and Sargeant, 1975), this study not only re-examined the
relationship between VO2 max and endurance capacity but also attempted to
separate local and central adaptations to training. This model was
adopted because of the suggestion that increases in endurance capacity
are the result of changes in the skeletal muscle (local) (Gollnick et al., 1973). Again, the increases in VO2 max were small when compared
with the improvements in endurance capacity. Improvements in the
trained leg (TL) were attributed to central and local adaptations to
training and in the untrained leg (UTL) to central cardiovascular
changes. The large increase in the endurance capacity of the TL (523%)
was 404% greater than that seen in the UTL, thus supporting the view
that increases in endurance capacity are largely the result of changes in the skeletal muscle rather than improvements in the central
cardiovascular system. The findings of this study clearly demonstrate that VO2 max is
a poor predictor of endurance capacity. It provides no information
regarding an individuals ability to endure exercise, i.e. the ability
to sustain a given submaximal work load, both before and after
training. It is suggested that the fitness of an individual may be
reflected not by their V02 max value but rather by the largest
fraction of that value which he or she can utilize during prolonged
periods of exercise.Read More
