          Abstract

          As interrogações clássicas dos jogos desportivos colectivos, o quê, quando, como e porque fazer, adquirem na situação de 1x1 em Futsal uma importância crucial, em virtude das características específicas desta modalidade. No presente artigo procura-se: (i) identificar as acções táctico-técnicas que são i nduzidas (activadas) pelo 1x1, e as que são indutoras (activadoras) da referida situação; (ii) descrever as características das situações de 1x1 que mais frequentemente induzem o desequilíbrio defensivo do adversário; (iii) fornecer, a partir dos resultados obtidos, algumas orientações práticas para o treino do 1x1. A amostra do estudo foi constituída por cinco jogos do campeonato nacional da primeira divisão, tendo-se registado 853 sequências e 8559 ocorrências. Em termos metodológicos foi utilizada a metodologia observacional, mais concretamente, a análise sequencial e a técnica de coordenadas polares. Recorreu-se ao software SDIS-GSEQ para o registo e tratamento dos dados. A partir dos resultados obtidos conclui-se que: prospectivamente, o 1x1 parece fomentar o desequilíbrio defensivo do adversário, uma vez que é activador de situações de falta e de remate; retrospectivamente, o 1x1 parece ser activado por condutas de condução de bola, combinação táctica com progressão e recuperação de bola; à medida que o 1x1 é realizado numa zona mais ofensiva do campo, parece aumentar a probabilidade de este originar um desequilíbrio na estrutura defensiva adversária; o drible de progressão e o drible para remate são os tipos de 1x1 que mais provocam o desequilíbrio defensivo do adversário; ao nível do contexto de cooperação, o 1x1 com vários apoios é aquele que apresenta maior probabilidade de conduzir a uma situação de remate.

          The classic questions of team sports, what, when, who and why do it, have a vital importance in Futsal 1 on 1 situations, due to the specific characteristics of this sport. In this paper it is intended: (i) to identify tactical-technique actions that induce or are induced by 1 on 1; (ii) to describe the characteristics of 1 on 1 situations that more often promote the rupture in opponent defensive organization; (iii) to provide some practical orientations for 1 on 1 training. The sample includes 853 sequences and 8559 conducts, registered from the observation of five matches of the National First League. Observational methodology was used, with special reference to the sequential analysis and polar coordinates technique. For the treatment of data SDIS-GSEQ software was used. From the results we conclude that: prospectively, the 1 on 1 seems to encourage opponent defensive rupture, since it activates fouls and shots at goal situations; retrospectively, 1 on 1 seems to be activated by ball conduction, tactical combination with progression in the field and ball recovery; the possibility of defensive rupture in the opposing team grows as 1 on 1 situation takes place closer to the opponent goal; dribble of progression and dribble for shot at goal, are the dribbling types that most induce defensive ruptures; in respect to the cooperation context, the 1 on 1 with various supports (pass lines) presents a larger possibility of originating a shot on goal.

          Soccer specific aerobic endurance training.

          In professional soccer, a significant amount of training time is used to improve players' aerobic capacity. However, it is not known whether soccer specific training fulfils the criterion of effective endurance training to improve maximal oxygen uptake, namely an exercise intensity of 90-95% of maximal heart rate in periods of three to eight minutes. To determine whether ball dribbling and small group play are appropriate activities for interval training, and whether heart rate in soccer specific training is a valid measure of actual work intensity. Six well trained first division soccer players took part in the study. To test whether soccer specific training was effective interval training, players ran in a specially designed dribbling track, as well as participating in small group play (five a side). Laboratory tests were carried out to establish the relation between heart rate and oxygen uptake while running on a treadmill. Corresponding measurements were made on the soccer field using a portable system for measuring oxygen uptake. Exercise intensity during small group play was 91.3% of maximal heart rate or 84.5% of maximal oxygen uptake. Corresponding values using a dribbling track were 93.5% and 91.7%. No higher heart rate was observed during soccer training. Soccer specific exercise using ball dribbling or small group play may be performed as aerobic interval training. Heart rate monitoring during soccer specific exercise is a valid indicator of actual exercise intensity.
