| ABSTRACT | |||
| Investigations in the physiological demands of soccer have identified
that a significant percentage of energy production in match performance
is provided through the aerobic pathways. It is therefore important to assess
maximal oxygen uptake (VO2Max) of players in order to evaluate
their aerobic fitness status and optimize their physical conditioning. However,
it is also important to consider the variation of (VO2Max) profiles
for soccer players, with differences having been identified in terms of
playing position as well as playing style. This paper reviews the academic
literature between 1996 and 2006 and reports on the methodologies employed
and the values obtained for stature, body mass and (VO2Max) profiles
of soccer players of different positions in professional Brazilian clubs
at U-17, U-20 and First Division levels. Indirect measurements accounted
for the majority of tests conducted at U-17 (70%) and U-20 (84.6%) levels
whereas at First Division level almost half of the (VO2Max) evaluations
were performed by direct measurements (47.8%). The mean (VO2Max)
profiles obtained for outfield players in U-17 was 56.95 ± 3.60 ml·kg-1·min-1,
58.13 ± 3.21 ml·kg-1·min-1 for U-20 players and 56.58 ± 5.03
ml·kg-1·min-1 for First Division players. In Brazil, the U-20
players appear to have highest VO2Max values, however the profiles
reported for all outfield positions in U-17 and First Division levels are
often lower than those reported for the same category of players from other
countries. This may be a reflection of the style of play used in Brazilian
soccer. This is further emphasized by the fact that the playing position
with the highest VO2Max values was the external defenders whereas
most findings from studies performed in European soccer indicate that midfielders
require the highest VO2Max values.
Key words: Soccer, maximal oxygen uptake, playing positions. |
