I personally disagree with the saying
that ‘age is just a number’. Age is not just a number; it is one of the
most important parameters that we all want to know so as to take
decisions.
Jose Mourinho is concerned about the age of his lead
striker, whose stated age is 31 but he thinks could be as much as 35.
Etoo’s ex-girlfriend says he is 39 years old.
I researched the
official ages of most of our ‘experienced and matured’ African stars and
interestingly all of them were between the ages of 31-33.
This
seems to be the age of ‘comfort’ and the interesting thing is some of
them have stayed at this age for a few years and never seem to be
growing up. The debate that rages on is whether their ages matter at
all?
Below is a well-written article that I’ve taken the pleasure to reproduce without any editing.
There
are certain immutable truths concerning the performance of the human
body as it ages, particularly as the athlete reaches age 40.
The
physical peak for most humans, in most sports, is between 25 and 35
years of age; during this peak period, the well-conditioned athlete can
create a confluence of muscular strength, peak cardiovascular and oxygen
transport, speed and reaction time, and mental capabilities (including
the ability to deal with competitive pressures), all bound together by a
desire to succeed.
The heart, as with every other human muscle,
will gradually lose efficiency and power over time. A typical
rule-of-thumb calculation to confirm the physiological fact of reduced
heart capacity is that utilized by the American College of Sport
Medicine: in males, 220—age = maximum heart rate (beats/minute); in
females, 226—age = maximum heart rate.
Athletes cannot train at a
maximum heart rate for extended periods; the usual target training rate
for a fit, healthy athlete will be approximately 80% of the maximum
rate. It is for this reason that, as an athlete ages, the heart's
ability to work is reduced.
The rule of thumb is not an accurate
predictor in every case; extensive research in the triathlon and
distance sports communities demonstrates that maximum heart rate may
vary significantly between athletes of equal abilities.
In sports
such as tennis, golf, and baseball, or at specific team sport
positions, such as ice hockey goaltender or the American football
quarterback, the mental training and experience components are of
greater importance to athletic performance.
With more training and experience, an athlete can remain competitive for a longer period.
The
competitions sanctioned by both the Professional Golfers Association
(PGA) and its European counterpart are evidence of ability of older
athletes to compete, as the so-called seniors tour in each organization
has a minimum age limit of 50 years or older.
Jack Nicklaus won
the prestigious Masters Championship in 1986 at age 46; there are
individual tournament winners on the PGA tour each season who are over
40 years of age.
However, for sports in which strength (both
muscular strength and bone density), oxygen uptake, and cardiovascular
efficiency are vital to success, the aging process may be slowed, though
never halted or reversed.
Since 1950, the average age of world
champion distance runners in the 3-mi (5,000 m) races through to the
26-mi marathons (42.2 km) ranges between 28 and 32 years of age.
From
this peak of ability, runners will continue to perform at levels close
to their personal best into their late 30s and early 40s; performance
then declines at a rate of approximately 2% per year through age 80.
Swimming,
which like running places a premium on cardiovascular strength, shows a
similar regression from best performance times as an athlete ages.
The
success of female swimmers at early ages (there have been numerous
Olympic gold medals and world records set by female swimmers under the
age of 20) is related to both the earlier physical maturation of female
athletes, as well as the physical dynamics of the female swimmer in the
water; the progressive decline in the performance of female swimmers due
to age is similar to that of male swimmers.
Consistent with
these physiological constants, the oldest gold medalist in the history
of all Olympic track and field events was Patrick McDonald, an American
hammer thrower, who won the 1920 competition at age 42.
The oldest Olympic track champion in the 1,500-m race was 31-year-old Albert Hill of Kenya, in 1988.
Female
competitors have the added variables of prospective pregnancy and
child-rearing, which will remove the athlete from intense training and
competition for an often-significant period.
Childbirth may also
change the physical shape of a female athlete, particularly in a
widening of the pelvis, which may impact subsequent athletic
performance.
In addition to the generalized impact that age
presents on injury and the body's ability to recover, age is a
significant reducing factor in the assessment of reaction time in
athletes.
"Reaction time" is the expression used to describe a
complex sequence of related actions when the body is called upon to
respond to a stimulus.
Every competitive sport involves a
reaction time; examples include the cricket batsman deciding whether to
swing at a particular ball, an ice hockey goalie moving to stop a shot,
or a sprinter exploding from the starters' block.
The speed with
which the athlete reacts is a combination of their ability to recognize
the required response, the choices available to them, the type of
reaction required, practice in responding to this situation, fatigue,
and the age of the athlete.
