VO2max changes in English futsal players after a 6-week period of specific small-sided games training

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

Questionnaire : Loss of Entertainment in Spanish Futsal (PEFSE)-Results Analysis

In the absence of questionnaires addressing the analysis of the rule’s change in futsal and the need to find an instrument that is capable of carrying out this objective, the aim of this study is to design and develop a questionnaire to assess the loss of entertainment in futsal. To do this, the sample consisted of 279 subjects with roles as a coach, player, physiotherapist, amateur referee and journalist since all of them are part of the sport. The instrument is based on the new rules imposed by FIFA in the kick-in and corner and their impact on the show. This descriptive cross-sectional study where is designed and implemented a closed-responses ad hoc questionnaire to subjects related with futsal in the first category to obtain objective information was undertaken. The analysis of data showed satisfactory results in terms of reliability and validity. It can be concluded that this scale is valid and reliable instrument to analyze changes in the rules of futsal
