“…The results obtained after the polar coordinates analysis with the focal behavior one-on-one outside the zone show a clearly defined tendency. Relationships of mutual excitement are established with a tight score but not managing to overcome the opponent, so those actions lead to situations without tactical advantage that support an offensive success achievement, executing outside the left zone, which is consistent with the results obtained in other studies where the most used areas were outside of the zone and the sides (Muñoz-Arroyave et al, 2015;Serna-Bardavío et al, 2017). On the other hand, the one-on-one outside of the zone presents a mutual inhibition relationship with the play inside the zone as well as an unbalanced score in favor.…”

“…One of the most recurrent offensive tactical means is the direct block (Nunes et al, 2016;Romarís-Durán, 2016), defined as the collective action of the two-on-two (2×2) play, where the attacker without the ball performs a block (hinders an opponent by placing himself/herself in his path) helping to his/her mate who is having the ball (Cárdenas, 2010;Muñoz-Arroyave et al, 2015;Nunes et al, 2016). It is so important that it is the most used action to end attack situations in ACB League (Romarís Durán et al, 2013).…”

“…OM has been successfully applied in basketball (Hernández-Mendo et al, 2000;Romarís Durán et al, 2013;Muñoz-Arroyave et al, 2015), highlighting the impact of using polar coordinate analysis as a specific technique for studying the relationships established among the behaviors happened (Nunes et al, 2016). It is a technique that has also shown useful for other collective sports studies as taken for soccer (Echeazarra-Escudero et al, 2015;Castañer et al, 2016Castañer et al, , 2017Maneiro and Amatria, 2018;Maneiro et al, 2019), handball (Sousa et al, 2015;Morillo-Baro et al, 2017;Jiménez-Salas et al, 2020a,b;Quiñones et al, 2020), or beach handball (Morillo-Baro et al, 2015;Vázquez-Diz et al, 2019a,b).…”

Nowadays, getting advantageous offensive situations in high-level basketball is being increasingly harder, so taking advantage of any situation in the game since the team has the ball is essential to be competitive. Therefore, the goal to achieve in this study is to evaluate using a mixed method strategy the behaviors happening in the application of the technical–tactical means performed in the transition play of professional basketball in Spain. An ad hoc observation tool made of 11 criteria and 83 exhaustive and mutually exclusive categories (E/ME) has been designed and validated by means of data quality and generalizability analyses. Indexes obtained show high reliability and validity allowing the proposed actions to be recorded (correlation coefficients are above 0.95 and generalizability coefficients are above 0.90 in all cases). A total number of 128 situations corresponding to eight games of Unicaja de Málaga in the Endesa League in the 18/19 season were observed with the Hoisan software. The analysis of the relationships among behaviors was performed using the polar coordinates technique where the one-on-one initiation, outside the zone, has been used as focal behavior. The estimation of the functions representing the vectors has also been performed to model the best fit that estimates, starting from a focal category, the relationship among this focal behavior and the rest of the mating behaviors for possible future observations. The results show significant relationships between the selected focal behavior and the mating behaviors, showing indications of behaviors allowing tactical interpretation of the game and the definition of intervention programs to improve the performance of the team.

“…This may be because the inside players tend to be the tallest and heaviest, while the outside players tend to be the quickest and most agile [46]. The predominant areas for the execution of the screens, regardless of success or failure, were the upper areas of the court, both right and left (55.5% and 40.4%, respectively), corroborating the data present in the literature [2,5,11,31]. The greater use of the top-right zone may be due to the predominance of players being righthanded and thus feeling more comfortable developing their game from this position [9,47].…”

“…The observational instrument was created ad hoc and consisted of eleven criteria and forty descriptors (Table 1 and Figure 1), which comprise a system of categories that complies with conditions of exhaustiveness and mutual exclusivity. The criteria were extracted from various research studies in the scientific literature [5,7,11,15,31]. The software LINCE v.1.4 and LINCE PLUS [32,33] were used as data registration tools.…”

Background: The objective of this research was to analyse the effectiveness and search for successful patterns in ball screens in the men’s 2019 Basketball World Cup. Methods: The sample consisted of 515 ball screens obtained in critical moments. LINCE software was used as a registration instrument by means of an observational instrument designed ad hoc. A descriptive analysis and chi-square tests (χ2) were performed with SPSS 25.0 and a T-patterns analysis with Theme 5 software. Results: The results indicate that the criteria that have the most influence on this type of action are the result of the team executing the screen (winning, losing or tying), the type of offense and the defence used on the ball screen. The most representative patterns of success tend to take place between 9–16 s of possession, with the screeners being inside players and the screened players being outside players, and it is performed in the upper areas of the court against an individual type of defence and ending with the screened player advancing towards the basket or passing to an open teammate. Conclusions: The data obtained will enable the coaching staff to train ball screens in accordance with specific game situations.

Although the full potential of observational methodology is realized through diachronic analyses, synchronic analyses can be used to investigate associations between categorical variables. Log-linear modeling is an appropriate method for investigating associations between three or more dimensions using multidimensional contingency tables. We provide a practical example of how we used log-linear analysis to study efficiency in a men’s basketball competition played by Spain’s top teams using a model containing three dimensions (and their respective categories): position of last pass before a shot, position of shot, and result of shot. The best-fit and most parsimonious model (i.e., the model that provided the best explanation of the observed frequencies in the contingency table and that contained the fewest effects) was a conditional independence model in which last pass position and shot position were associated independently of the categories in the shot result dimension and the interaction between shot position and shot result was not affected by the categories in the last pass dimension. Estimation and subsequent interpretation of the significant parameters in the selected model showed how log-linear modeling can provide basketball coaches with practical insights within an observational methodology study.
