The efficiency of actions of goalkeepers from sports effective teams in a game of futsal in matches of the final tournament of the World and European Championships in 2012

Background: The purpose of the study was to develop a model mapping the efficiency of actions of futsal goalkeepers based on observation of their game in eight matches of the cup finals the World and European Championships in 2012. Material/Methods: Data about the game were recorded on originally developed observation sheets. Activity, effectiveness and reliability of particular offensive and defensive actions aiming at achieving objectives of the game were investigated. Results: It was found that in attack futsal goalkeepers mostly perform actions whose aim is to gain the playfield with the ball by passing it with a foot from the ground and to keep the ball by receiving it from partner. In turn, in defence, they mostly prevent losing goals by pushing the ball. Conclusions: The created models of players’ performance should be used to create models shaping the game of players of a lower level of proficiency in order to improve the efficiency of their games as well as to develop individual programs of training for futsal goalkeepers.

Constructing an indicator for performance effectiveness of futsal game

The research aimed at constructing ( an equation for performance effectiveness) during games as an indicator to reach the efficiency of players performance. The descriptive approach method by survey style was used. The sample of the study consisted of futsal players of premier league clubs and elite clubs (Alfutuwwah club, Alshimal Gas Club, Balad Club and Ashti Club). The sample consisted of (92) players. Questionnaire and observation were used as a means for collecting data and through editing and designing the form of analyses, then finding its scientific basis, followed by suggesting an equation for performance effectiveness and finding its scientific basis in such as validity, and index of reliability then the validity of the criterion, while reliability was reached at by reconsider video analysis. Then the researchers used the mean, standard deviation, coefficient of skewenss, mode and chi- Square, all of which as statistical means. Both researchers verified the normal distribution of the equation then they found the standard levels and degrees of the equation. Both researchers recommended for what accords with the results of the research.

A Pilot Study of the Physiological Demands of Futsal Referees Engaged in International Friendly Matches

Futsal is a FIFA sanctioned form of 5-a-side football. It is controlled by two referees who run up and down the touchlines either side of the pitch ensuring the laws of the game are enforced. The match is played over two halves of 20 minutes, with the clock being stopped every time the ball goes out of play; so each half can last up to 40 minutes including stoppage time. To date there has been minimal research which has looked at the physiological demands of refereeing futsal. This pilot study was undertaken over consecutive days when two International futsal games took place involving four referees. Heart rate, core temperature, blood lactate and hydration status were monitored prior to the match, again at half time and at full time. The results showed that the referees operated at between 81 and 84% Heart Rate Maximum (HRmax). There was a marked difference between the first and second referee in both games and between the first and second halves. Core temperature increased during the game with the referees becoming progressively dehydrated towards the end of the game. Blood lactate was found on average to be higher at the end of the first half compared to the end of the second half (2.33 vs. 1.8 mmol.l-1) and referees in the first game had readings higher than the second game (HT 2.8 vs. 1.9 mmol.l-1; FT 2.4 vs. 1.2 mmol.l-1). In conclusion, the major findings show that further investigation is needed into the physiological demands of Futsal Refereeing and that in future, activity profiling should also be considered.

Efeito de quatro dias consecutivos de jogos sobre a potência muscular, estresse e recuperação percebida, em jogadores de futsal

O objetivo desse estudo foi analisar o efeito de jogos de futsal realizados em dias consecutivos sobre o desempenho em testes de saltos verticais e sobre o estresse e a recuperação de atletas dessa modalidade. Participaram deste estudo 11 atletas do sexo masculino (24,3 ± 5,0 anos, 1,73 ± 0,07 cm, 75,7 ± 9,0 kg, 11,2 ± 4,1% de gordura), pertencentes a uma equipe de futsal. A equipe foi monitorada durante a fase final dos Jogos Abertos do Paraná, com jogos realizados em quatro dias consecutivos. O RESTQ-Sport foi aplicado antes e após a competição, e os testes de "squat jump" (SJ) e de salto vertical com contramovimento (CMJ) foram realizados na manhã de todos os dias de jogos. O SJ apresentou uma provável diminuição (0/34/66%) antes do segundo jogo comparado com antes do primeiro, uma muito provável diminuição (0/3/97%) antes do terceiro jogo comparado com antes do primeiro e uma provável diminuição (2/20/78%) antes do quarto jogo comparado com antes do primeiro. O CMJ apresentou uma provável diminuição antes do segundo (0/19/81%), terceiro (3/20/77%) e quarto jogo (1/10/89%) em relação à antes do primeiro. A escala recuperação física do RESTQ-Sport foi menor no pós-competição, comparada com o pré-competição (p < 0,05) e a escala fadiga foi maior no pós-competição comparada com pré-competição (p < 0,05). A diferença entre o Σ das escalas de recuperação e o Σ das escalas de estresse no pós-competição (7,5 ± 9,8) foi menor que o pré-competição (9,8 ± 9,1; p = 0,03). Em conclusão, o decréscimo no desempenho de saltos verticais e as alterações deletérias nas escalas do RESTQ-Sport sugerem que houve acúmulo de fadiga ao longo de jogos de futsal realizados em dias consecutivos.

Futsal and Continuous Exercise Induce Similar Changes in Specific Skeletal Muscle Signalling Proteins

Exercise elicits skeletal-muscle adaptations which are important for improved health outcomes. We compared the effects of a futsal game (FUT) and moderate-intensity continuous exercise (MOD), on the skeletal-muscle protein signalling responses in young, healthy individuals. 16 men undertook an incremental exercise test and a resting muscle biopsy performed >48 h apart. They were then randomly allocated to either FUT (n=12) consisting of 2 x 20 min halves, or MOD (n=8) consisting of a work-matched running bout performed at an intensity corresponding to the individual ventilatory threshold 1. Work matching was achieved by means of triaxial accelerometers. Immediately after FUT and MOD, participants underwent a second biopsy to assess exercise-induced changes in protein signalling. Total and phosphorylated protein abundance was assessed via western blotting. Both FUT and MOD altered signalling responses in skeletal muscle. FUT increased total ATF2 protein abundance (p=0.048) and phosphorylation (p=0.029), while no changes occurred with MOD. Both exercise regimes increased ACC phosphorylation (p=0.01) and returned a trend for increased p38MAPK phosphorylation. Futsal may be employed as an alternative to continuous exercise to elicit muscle adaptations which may be associated with improved health outcomes. As only FUT increased ATF2 activation, this protein might be a target of future investigation on exercise-induced signalling.

The Method of Goalkeeper's Evaluation in Futsal

Background: The aim of this study was to develop a research tool used to assess the efficiency a goalkeeper’s actions in a game of futsal. Material/Methods: Author’s own proposal of an observation sheet was created and subject to a validation procedure. To assess intra-rater reliability and inter-rater reliability, the ICC test was used. Results: There was a strong compatibility of ratings of the intra-rater reliability – 1.00 (95% Cl 1.00-1.00) and the inter-rater reliability – 0.99 (95% CI 0.99-1.00), which proves the reliability of the proposed research tool. Conclusions: The developed sheet allows the registration and evaluation of individual performance and cooperation in terms of goalkeeper’s game objectives pursued both in offence and defence.

Coordination tendencies are shaped by attacker and defender interactions with the goal and the ball in futsal

This study examined how the location of the goal and ball constrained the interpersonal coordination tendencies emerging of attacker-defender dyadic systems in team sports. Additionally, we analysed how the positioning of defenders constrained the emergent coordination tendencies between the ball carrier and supporting teammates. To investigate these tendencies in team sports, ten futsal games were filmed to observe inter-individual interactions. Movement trajectories of players and ball were digitized during 52 outfield attacker-defender interactions involving thirteen goal-scoring sequences. Relative phase was used as a measure to express participant coordination tendencies in these dyadic systems (in-phase or symmetry – 0°; anti-phase or anti-symmetry – 180°). Stable in-phase patterns of coordination emerged between specific values of an attacker’s distances to defenders and the goal (19% frequency from 0° to 29° of phase relations) and between specific values of distances of ball carriers to defenders and teammates (14% frequency from 0° to 29° of phase relations). A stable pattern of coordination of −60° emerged between values of an attacker’s distances to defenders and the ball (18% frequency from 0° to 29° of phase relations). Distances of attackers to the goal and ball, and distances of ball carriers to defenders, seemed to be coupled in a specific manner to guide interpersonal coordination tendencies between players during competitive performance in the team sport of futsal.

Effects of repeated short-term futsal practice games on urinary catecholamine levels

Introduction: Catecholamines have been known as an index of sympathetic nervous function, usually acting as a trigger for the adaptation of physical systems to the demands of exercise. A futsal game has high physical demands, which are known to act on stress hormone levels such as catecholamines. The non-invasive measurement of urinary catecholamines may offer a more suitable index than altered plasma catecholamines in sympathetic-adrenal activityduringvigorous intermittentexercise in futsal-specific condition. The purpose of this study was to determine the effects of repeated bouts of short-term futsal games on urinary catecholamine levels. Methods: Nine recreationally active male futsal players served as the subjects (age: 19.4±0.7 year; height: 170.0±4.4 cm; body mass: 61.7±7.6 kg; body fat: 15.5±5.1%; BMI: 21.3±2.1 kg/m2). The protocolwas composed of 5min ofwarm-up, six 7-min periods of game with 1min of rest, and cool-down. Spot urinary samples were obtained before (Pre) and after (Post) overall session for the later analysis of the urinary catecholamine levels (epinephrine, norepinephrine and dopamine). The urinary catecholamine levels were analyzed by high-performance liquid chromatography. Results: A Student’s t-test represented a significant elevation at the levels of urinary free norepinephrine (Pre: 97.7±57.7; Post: 432.9±190.0 g/L, p<0.05) and epinephrine (Pre: 18.1±9.8; Post: 65.9±29.0 g/L, p<0.05) except for dopamine (Pre: 572.9±245.4; Post: 1341.6±639.2 g/L) after exercise. Significant changes were found at the levels of urinary total protein after exercise compared to the baseline (Pre: 6.0±8.2; Post: 26.9±27.9mg/dL, p<0.05). Discussion and conclusions: Previous research has reported augmentation of urinary catecholamine levels following intermittent exercise. Thus, the concentration of urinary catecholamine may provide information about the psychological and physiological stress levels of athletes during training andcompetition. The results of the present study indicate that elevated urinary catecholamine levels may be useful to comprehensively understand exercise intensity during repeatedbouts of futsal-specific intermittent exercise.

Improving Passing Actions in Team Sports by Developing Interpersonal Interactions between Players

We investigated how interpersonal coordination tendencies of players in Futsal constrained performance of passing actions. To achieve this aim, we digitized 24 digital video film clips of attacking phases in competitive Futsal games. Values of interpersonal distance between players were recorded from the moment at which a teammate performed the pass to the ball carrier, to the moment of pass initiation by the ball carrier. Our results revealed that performance of passing actions was constrained by a convergence in interpersonal distance values between players. Pass efficacy seemed to be constrained by changes in interpersonal distance values between the ball carrier and the 2nd defender without a correspondent adaptation in ball velocity. Based on our results, we suggest three training phases for developing passing performance in Futsal by manipulating key constraints in the performance environment relative to the interpersonal distance values between players.

ANÁLISE DE FALTAS COM BARREIRA EM JOGOS DE FUTSAL FEMININO DE ALTO RENDIMENTO

This paper has the purpose to analyze offensive actions of fouls with hurdles in high level female futsal. It was verified the goals efficacy and site of fouls in distinctive zones in the offensive court. It was observed 89 (5,93 + 3,08) actions, extracted from 15 futsal games of Brazil Clubs Championship. The results indicated an efficacy of 5,62%; a deffensive trend related to avoid fouls in the center of the court and close to the goal positions; the greatest part of the goals came from the central fouls and greater efficacy of the goals occurred in these situations rather than in the lateral fouls; a greater efficacy was found in the goals originated of half-distance fouls when compared to the fouls closer the goals. It was concluded that we need to increase the effectiveness of fouls with hurdles, especially in lateral areas. Keywords : Futsal. Tactics. Game Analysis. Female Gender.

Spatial dynamics of team sports exposed by Voronoi diagrams

Team sports represent complex systems: players interact continuously during a game, and exhibit intricate patterns of interaction, which can be identified and investigated at both individual and collective levels. We used Voronoi diagrams to identify and investigate the spatial dynamics of players’ behavior in Futsal. Using this tool, we examined 19 plays of a sub-phase of a Futsal game played in a reduced area (20m2) from which we extracted the trajectories of all players. Results obtained from a comparative analysis of player’s Voronoi area (dominant region) and nearest teammate distance revealed different patterns of interaction between attackers and defenders, both at the level of individual players and teams. We found that, compared to defenders, larger dominant regions were associated with attackers. Furthermore, these regions were more variable in size among players from the same team but, at the player level, the attackers’ dominant regions were more regular than those associated with each of the defenders. These findings support a formal description of the dynamic spatial interaction of the players, at least during the particular sub-phase of Futsal investigated. The adopted approach may be extended to other team behaviors where the actions taken at any instant in time by each of the involved agents are associated with the space they occupy at that particular time.

Informational constraints shape emergent functional behaviours during performance of interceptive actions in team sports

Objectives This study aimed to explain how defenders intercept the trajectory of a passing ball by understanding how they coupled their actions to critical information sources in a competitive performance setting in team sports. Design Time series data on movement displacements of fifteen senior male futsal performers were recorded and digitized during nine competitive futsal games. Method Performance was recorded by a digital camera and digitized with TACTO software. The spatial–temporal dynamics of performers during ten intercepted and ten non-intercepted passes were compared. Time to ball interception was calculated by the difference between the time of each defender to an interception point in ball trajectory and the time of the ball’s arrival at the same interception point. Initial distances between defenders and ball and velocity data of defenders and ball over time were also recorded. Results Time to ball interception revealed positive values when passes were not intercepted, and negative to zero values when passes were intercepted. At the moment of pass initiation defenders’ distances to the ball constrained their possibilities for successful interception. Analysis of defenders’ adaptations to the environment revealed that continuous changes in the defenders’ velocities constrained their success of the interception. Conclusions Intercepted passes seemed to be influenced by the continuous regulation of a defender’s velocity relative to the ball’s trajectory. Time to ball interception is a variable that captured the emergent functional behaviours of players attempting to intercept the trajectory of a pass in the team sport of futsal.

Interpersonal coordination and ball dynamics in futsal (indoor football)

Here, we report an investigation of the patterned movement behavior of players for a specific sub-phase of the game of futsal, namely when the goalkeeper for the attacking team is substituted with an extra outfield player. The movement trajectories of the ball and players were recorded in both lateral and longitudinal directions and investigated using relative phase analysis. Some differences in phase relations between different playing dyads were noted, indicating specificity of phase attractions, or otherwise, for certain players. In general terms, the defenders demonstrated strong in-phase attractions with the ball and with each other, whereas weaker phase attractions, indicated by increased relative phase variability, were observed for the attackers and ball, as well as between attackers themselves. These results demonstrate different coordination dynamics for the defending and attacking dyads, from which we interpret evidence for different playing sub-systems consistent with different team objectives linked together in an overarching game structure. In keeping with dynamical systems theory for complex systems, we view this sub-phase of futsal as being characterized by coordinated behavior patterns that emerge as a result of self-organizing processes. These dynamic patterns are generated within functional constraints, with players and teams exerting mutual influence on each other.

Physiological Demands of an Intermittent Futsal-Oriented High-Intensity Test

The aim of this study was to provide evidence for specific physiological demands of a futsal time-motion analysis devised progressive and intermittent shuttle-running test (futsal intermittent endurance test [FIET]). Eighteen full-time professional futsal players (age 20.6 +/- 3.1 years, body mass 71.6 +/- 8.5 kg, height 175 +/- 7.9 cm) volunteered to participate in this study. In a random order and on separate days, they performed the FIET and a treadmill test (TM) to assess aerobic fitness. Physiological demands were examined by monitoring exercise heart rates (HRs), O2, and blood-lactate concentration (BLac) during FIET and TM conditions. During the FIET, players covered 1,464 +/- 136 m attaining a mean speed at exhaustion of 16.5 +/- 0.6 km h. The mean FIET duration was of 13.24 +/- 1.13 minutes. Peak O2, HR, and BLac were 95 +/- 6.4, 99 +/- 2, and 108 +/- 25% of treadmill O2max, HRmax, and BLac, respectively. Large correlations were found between speed at ventilatory threshold and maximal speed at O2max with FIET performance (r = 0.60 and 0.61, p < 0.01, respectively). Peak O2 during the FIET was significantly lower than O2max. Although there was no mean difference between peak exercise HR in the TM and FIET conditions, significant intraindividual bias was evident. This study showed that FIET heavily stresses both the aerobic and anaerobic energy systems to a level that is similar to what was reported in futsal game play. Coaches may use the FIET to examine futsal players' ability to cope with intermittent high-intensity exercise. It is suggested that the highest HR found during the FIET should be regarded as peak HR and not as individual HRmax.

Effectiveness of Active Versus Passive Recovery Strategies After Futsal Games

This study aimed to investigate the effects of immediate postgame recovery interventions (seated rest, supine electrostimulation, low-intensity land exercises, and water exercises) on anaerobic performance (countermovement jump [CMJ], bounce jumping, 10-m sprint), hormones (salivary cortisol, urinary catecholamines), and subjective ratings (rate of perceived exertion [RPE], leg muscle pain, Questionnaire of Recovery Stress for Athletes [RestQ Sport], 10-point Likert scale), and hours of sleep of futsal players. Heart rate (HR), blood lactate, and RPE were used to evaluate the intensity of 4 futsal games in 10 players using a crossover design (P < 0.05), randomly allocating athletes to 1 of the 4 recovery interventions at the end of each game. No significant difference emerged between HR, blood lactate, RPE, and level of hydration of the games. A significant difference (P < 0.001) between games emerged for total urinary catecholamines, with an increase from the first to the second game and a gradual reduction up to the fourth game. After the game, significant reductions in CMJ (P < 0.001) and 10-m sprints (P < 0.05) emerged. No significant difference was found between recovery interventions for anaerobic performances, hormones, muscle pain, and RestQ Sport. Even though a well-balanced diet, rehydration, and controlled lifestyle might represent a sufficient recovery intervention in young elite athletes, the players perceived significantly increased benefit (P < 0.01) from the electrostimulation (7.8 +/- 1.4 points) and water exercises (7.6 +/- 2.1 points) compared to dry exercises (6.6 +/- 1.8 points) and seated rest (5.2 +/- 0.8 points.), which might improve their attitude toward playing. To induce progressive hormonal adaptation to the high exercise load of multiple games, in the last 2 weeks of the preseason, coaches should organize friendly games at a level similar to that of the competitive season.
