Anthropometry is the process of
measuring physical dimensions of the human body. Anthropometry is used
in sports science for evaluating the athletes' size, shape, body
proportions, body composition and degree of asymmetry between the
dominant and non-dominant limbs. The measurements such as stature, body
mass, skinfold thickness, girth measurements which are assessed help to
derive at body fat %, lean muscle mass and somatotype. This information
can be used to customise training programmes and nutritional
intervention. Anthropometry has the potential to be a valuable tool in
evaluating and monitoring the athlete.
A high body fat percentage is seen as
a negative, and indicates that an individual has a low lean muscle
mass, which would not only directly affect strength and power output,
but also recovery from high intensity bouts of exercise. The ability to
shuttle metabolites (such as lactate) post-training is largely affected
by the amount of lean muscle mass, therefore if an athlete has a
relatively low lean muscle mass it would delay recovery post high
intensity training sessions.
Aerobic Capacity
Aerobic capacity is scientifically
measured in terms of the Maximal Oxygen Uptake or VO2max. It is defined
as an individual s maximum capacity to consume oxygen and further, to
utilize this oxygen at a cellular level by the body. Traditionally
VO2max has been considered the Gold Standard for endurance performance
assessment with Maximum oxygen uptake values, in healthy individuals,
ranging from 25 to 80 ml. per kg per min. This is influenced by a number
of variables, including, age, gender and level of aerobic fitness.
However, VO2max is not the only
determinant of endurance performance, with other factors, predominantly
those at the local tissue level, playing a role in endurance
capabilities.
Depending on the nature of the sport
there are different ways to measure aerobic capacity. Endurance sports
such as track running, road running, cycling will typically use a
treadmill or cycle VO2max test. The lactate threshold, peak power output
and VO2 are among the important parameters assessed.
Field sports such as hockey or
football use aerobic capacity tests like the shuttle run (Bleep Test,
Yo-yo intermittent recovery test) to suit the nature of the sport, where
athletes start and stop.
Anaerobic Capacity
Operating within the body are four
distinct energy systems. Two of these energy systems are anaerobic
(oxygen independent), and two are aerobic (oxygen dependent). Testing
manuals traditionally categorise exercise test as being either aerobic
or anaerobic. In certain sporting codes such as sprint cycling and
rowing the athlete is more dependent on their anaerobic capacity. For
these sports we use tests such as the Wingate Anaerobic Power test.
For field sports where there may be
an anaerobic component we would use a test such as the Repeat Sprint
Ability Test to determine if an athlete can cope with the sports
anaerobic requirements.
Agility
Agility is the ability to accelerate, decelerate and change direction at maximal speed.
This is an important component of
most field and court ball sports as players need to be able to be mobile
on the field and court of play. Speed and agility are distinct physical
qualities that require specific training and testing.
Scientific tests that look at an
athlete agility include the T-Test and the Illinois Agility Test which
are the best practice assessments for high performance testing.
Maximum Running Speed and Acceleration
The purpose of these tests is to
determine the athlete's maximum sprint speed and their ability to
accelerate from a stationary position.
