The main point in Ericsson et. Al.(1993) is that in order to achieve expert
performance, one must engage in deliberate practice with the explicit goal of
constant improvement. This theory further dismisses to a large extent the role
of genetics, in which Ericsson reasons that there has been no great correlations
between the attainment of superior performance and inherited traits. The
purpose of this paper is to show agreement with Ericsson’s theory, but only to
the extent that deliberate practice is just one of many factors which must be
included in order to gain expert status. Also, the task at hand can be a major
determinant of how large a role practice plays in improvement. For example, in
endurance sports such as marathon running, some are genetically endowed with a
high aerobic capacity/VO2 max, and if these “special” people develop and
impr
status. In contrast, the “average” person may also engage in an equal amount of
practice but will never be able to achieve that same level of performance
because their body is physiologically incapable. Furthermore, physiologist Dr.
Astrand contends that up to 90% of the variance in aerobic performance is due to
one’s genes, regardless of training programs. (McArdle,1994). But sports like
golf are probably influenced very little by genetics because skill acquisition
far overshadows physical ability. History provides many examples of athletes
who apparently has a poor genetic endowment, yet by hard training and motivation
went on to international success (Shepard,1987). In conclusion, expert
performance is most likely due to a complex interaction of psychological,
physiological, and biomechanical factors (Powers, 1994); factors whose
importance is dependent on the nature of the task at hand.
