Futsal is a high-intensity, intermittent sport where accelerations and
short sprints are performed at maximal or sub-maximal intensity. These
efforts are interspersed by brief recovery periods, during 2 halves of
20 minutes stopping clock. Aerobic endurance inevitably plays a key role
in the players’ performance. The aim of this study was to analyse the
VO2 max progression and the agility (with and without ball) of English
futsal players during a 6-week period of small-sided games practice. Two
teams volunteered to participate in this study; an experimental group
(EG), which performed a specialised small-sided training regime and a
control group (CG) (normal training regime). VO2max was estimated from
the results of the 20-metre Multi-Stage Fitness Test. The VO2max of the
futsal players in the EG improved significantly (58.73±2.41 ml/kg/min
vs. 60.11 ± 2.99 ml/kg/min, p=0.04). The same player's agility and
agility with ball performance did not report any significant changes in
either group. The results showed that periodisation, training sessions
and methods based on small-sided games, which implied a change in the
number of players, the size of the pitch and the task constraints, were
adequate to increase aerobic endurance.
