(2020-10-26) Pizarro, David; Práxedes , Alba; Travassos, Bruno; Moreno, Alberto
Based on ecological dynamics approach, non-linear pedagogy (NLP) have emerged with the goal of promoting a holistic approach through the use of small-sided and conditioned games (SSCGs), to optimize specific tactical defensive and offensive behaviors of players. This study analyzed the indirect effects of an intervention program, based on NLP (task design based on tactical principles of attack and numerical advantage of attacking team), in decision-making (DM) and execution (Ex) in defensive technical–tactical actions in U16 futsal. Eight futsal players (U16 years) participated in 12 training sessions, spread over two phases: preintervention and intervention. The Game Performance Evaluation Tool (GPET) instrument was used to analyze the DM and Ex of 2,600 defensive actions measured during competitive matches. Results showed significant improvements in marking actions (to the player with the ball: DM, p = 0.001; Ex, p = 0.001; and to the player without the ball: DM, p = 0.039; Ex, p = 0.046), improvements in blocking actions (DM, p = 0.015), and improvements in help-coverage actions (Ex, p = 0.014). No significant differences were found in the interception and tackling actions. This study has shown evidence that the NLP approach is an appropriate theoretical framework to enhance acquisition of defensive tactical behavior in futsal. However, not all actions improved. Therefore, coaches should design representative tasks to optimally develop technical–tactical training processes based on the phases of futsal game (offensive and defensive) and considering the level of opposition.

Effects of a Nonlinear Pedagogy intervention program on the emergent tactical behaviors of youth footballers.
(Routledge, 2019-02-14) Práxedes, Alba; del Villar, Fernando; Moreno, Alberto; Gil-Arias, Alexander; Davids, Keith
Purpose: This study analysed the effects of a training intervention programme using principles of Non-Linear Pedagogy (NLP) on the decision making (DM) and performance behaviours (P) of youth footballers. Method: 19 footballers (U12 yrs) participated in 14 training sessions, spread over three phases: Pre-intervention, Intervention, Retention. The intervention was based on Small-Sided and Conditioned Games. We assessed progress during the intervention phase at two different points: intermediate and final. The GPET instrument was used to analyse the DM and P during the completion of 3208 passes in the intervention. Results: Results shown significant improvements in the DM and P after the intermediate and final points of the acquisition phase. Moreover, significantly higher values were also obtained in both variables in the retention, compared to the pre-intervention phase. Conclusion: Results indicated that the NLP intervention programme was effective in improving both aspects of team games performance in youth players, with effects consolidated over time
Floaters as coach´s joker? Effects of the floaters positioning in 3vs3 small-sided games in futsal. International Journal of Performance Analysis in Sport
(Routledge Journals, Taylor & Francis LTD, 2021-06-03) Pizarro, David; Práxedes , Alba; Travassos, Bruno; Gonçalves, Bruno; Moreno, Alberto
The aim of this study was to analyse the effects of floater positioning within futsal Gk+3vs3+Gk SSGs on youth players’ tactical and physical performance. An independent measure approach under four experimental conditions was carried out: Floaters Off (FO), Goal Line Floaters (GLF), Lateral Floaters own court sidelines (LFocsl) and Lateral Floaters full court sidelines (LFfcsl). Thirty male futsal players (U19 age category) participated in the study. Players’ activity was assessed using WIMU PROTM and heart rate (HR) was recorded by HR monitors during the SSGs. Results showed significant differences in the physical variables (ρ ≤ 0.05), not finding such differences in the tactical variables analysed. However, significant differences were observed in relation to the spatial occupation areas. GLF is related to higher distance and speed variables, being the most demanding SSG; in LFocsl, lower HR values were obtained, and FO is linked to the acceleration and deceleration variables, being an indicator of futsal performance. These findings should be considered for the design of futsal training tasks, according to the context (team, players . . .) and time of the week and the season, since they allow the development of the variables described by optimising training time with the ball.
Level of opposition constrains offensive performance in consecutive game situations. An analysis according to game principles
(Routledge, 2021-01-24) Práxedes, Alba; Pizarro, David; Travassos, Bruno; Domínguez, Miguel; Moreno, Alberto
Background In the last few decades, Nonlinear Pedagogy (NLP) has emerged with the goal to promote a holistic approach through the use of Small-Sided Games (SSG), to optimize specific tactical defensive and offensive behaviours of players. These SSG are designed through the manipulation of relevant task constraints. Specifically, the balance on the number of outfield players is a constraint that has been recently studied because it can change players’ behaviour. However, most of the studies in this domain have only analysed the acute effects of the manipulation of different SSG without any idea about the implications for learning or to improve the transfer between practice tasks to the context of performance. Purpose The main purpose of this study was to understand the effect of the use of a task of numerical superiority in attack (5 vs 4; NS) before a task of equal number of player in comparison with the use of only two numerical equality (5 vs 5; NE) tasks. A second objective was to examine this effect according to the game principles: keep the ball possession and progress to the goal. Method Twenty footballers (U14 yrs), grouped in teams of five players, participated in this study. Each team performed two different sequences of SSG (NS + NE and NE + NE) and in two different conditions regarding the game principle. 2176 actions were analysed. Decision-making was measured through the GPET instrument. Also, it was assessed the duration of ball possession and the number of ball touches through a hand notation analysis system. Results Results show a tendency to decrease the offensive performance in the sequence (NS + NE). However, if we compare both initial situations, significant higher values were observed in the situation with NS. In addition, regarding the two final situations, there are hardly any differences between them. Conclusion This study highlighted some key pedagogical principles of the constraints-led approach for designing training environment in team games. Coaches in formative stages should promote unequal game situations with superiority number of players in attack, to facilitate the decision-making and develop the technical skills thanks to a greater participation and a greater duration of ball possession. As learning progresses, coaches should design equal situations to facilitate an adaptation to the real game and promote long-term adaptations on players’ performance. Finally, the game principle is another constraint to take into account since it promotes variability and boosts the discovery and exploration of players’ movement solutions.
