The Relative Age Effect (RAE) in sport is defined as the age difference in the same sport group. This chronological difference implies a different level of sport experience and performance due to ...developmental and maturational processes. The aim of the present study was to analyze the relative age effect in elite u-18 basketball according to playing positions. The variables analyzed were: date of birth, playing position and technical-tactical performance indicators in basketball (TTPI). A descriptive analysis was carried out to characterize the sample, a lineal regression was used to analyze the influence of the date of birth on basketball performance and finally an ANOVA and discriminant analysis were performed to identify the differences among different playing positions. The results show the existence of the RAE in the top European Under-18 basketball competition (S1 = 67%; S2 = 33%). Performance indicators which are predictors of the birth quarter (p< .05) were only found in the small forwards (defensive rebounds (β: -.463) and fouls received (β: -.140)) and in the centers (three point throws scored (β: -.321) and tried (β: .342)). These results may be of use for coaches and clubs when recruiting players for each playing position. Older forwards and centers are capable of performing at a higher level. Therefore, clubs have to sign up those players born at the beginning of the year.
Planning the learning task is one of the principal actions that a teacher should engage in, and it is important to know how teachers in the pre-service phase plan learning and communication tasks and ...the feedback that they use in the classroom. The aim of the present study was twofold: i) to characterize the learning tasks designed by the pre-service physical education teachers; and ii) to identify the relationships between the variables that define the learning tasks and the phases into which a session is structured in Physical Education Teacher Education (PETE) in the pre-service phase. The sample comprised 695 learning tasks designed by fourteen pre-service phase teachers. The independent variable was the lesson structure and the dependent variables were the learning means, the game situation, the game phase, the space where the students practice, the use of the ball in the task, and the kind of feedback provided in the learning tasks. The high predominance of exercises, unspecific games, and no opponent situations, coupled with the low percentage of reflexive feedback, indicates that the pre-service teachers give prevalence to technical over tactical learning. In addition, pre-service teachers show preferences for some of the task characteristics for each part of the lesson structure. Teachers in PETE pre-service phase tasks tend to follow a more traditional methodology, despite having received information about the different methods of sports teaching in their initial training. The current findings seems to indicate a resistance to changing a traditional model for other models centered on game comprehension.
The load in tasks planned for sports teaching in physical education classes has received little attention. The purpose of this study was therefore to analyze the external load, eTL, in the tasks ...designed by physical education teachers from the in-service and pre-service stages, for teaching handball in primary education, and to compare them with the tasks included in the lesson plans designed for handball using the tactical games teaching model. An associative, comparative and cross-sectional methodology was used. Twenty-three teachers, five in the in-service phase and eighteen in the pre-service phase, designed lesson plans for teaching handball, which were compared with lesson plans validated by a panel of experts. The analysis was performed on 1,232 tasks or analysis units. eTL was categorized using the Integrated analysis system of training tasks (SIATE) instrument. A descriptive and associative analysis was made of the variables that make up the eTL and an inferential analysis of the eTL using non-parametric tests. The total eTL of the tasks planned by the in-service and pre-service teachers was low, and significantly lower than the tasks planned using the tactical games model, which showed a high level.
The assessment of learning in basketball in the PE class, and in training sessions of young players, requires valid, reliable, and trustworthy tools. The purpose of this research was to design and ...validate the Basketball Learning and Performance Assessment Instrument (BALPAI) that assesses simultaneously decision making, technical execution and efficacy. The play actions are codified using a categorical system, awarding a score for each category (1 = inadequate action; 2 = neutral action 3 = adequate action). An example of a summative procedure for assessing decision making in dribbling is: (1) Dribbling to a place where there is defensive pressure and there is a free teammate able to receive the pass; (2) Dribbling to a place where there is defensive pressure or a free teammate able to receive the pass; (3) Dribbling through a space where there is no defensive pressure and no free teammate able to receive the pass.
A pilot study was performed following this procedure. A group of 13 experts participated in the assessment of the 33 elements (66 items) included in the BALPAI. Aiken's V formula was used to analyze content validity, and internal consistency was calculated using Cronbach's α. Inter-observer reliability was determined among three observers who used the BALPAI to record the play actions in a 3 × 3 basketball match (N = 45 possessions) and was calculated with the Multirater κfree, obtaining an almost perfect agreement with values between 0.84 and 1.
The BALPAI has very high internal consistency (0.969), Interobserver reliability was almost perfect (>0.84 in all items) and Aiken's V coefficient (>0.71 in all items) attained a high value.
The BALPAI proved to be a valid tool, with high internal consistency and reliability that makes it possible to perform a complete assessment of basketball in PE classes.
Currently, the number of women involved in sport is increasing. Although, research on their characteristics and performance is scarce. A great amount of research on men's basketball is available, but ...it is unknown if it can be applied to women's basketball. The objective of this research was to characterize the internal and external load performed by female basketball players during training and sports competition according to playing positions through inertial devices. The participants in the following study were 10 amateur basketball players who competed at regional level (21.7 ± 3.65 years; 59.5 ± 12.27 kg, and 168.5 ± 3.56). Data were collected in games of the final phase (
= 8) and from 5 vs. 5 training tasks (
= 47). All the analyses were run according to playing positions. Each player was equipped with a Garmin
Heart Rate Band and Wimu
inertial device that monitored physical activity and movement in real time. The results obtained showed that the load experienced during competition was significantly higher (
< 0.001) than during training (Heart Rate, Player Load, Steps, Jumps, and Impacts). There were also differences according to playing positions, mainly between the backcourt and frontcourt players (
< 0.001). The players must work in higher areas of heart rate during training, mainly in Z4 and Z5, increasing their HRmáx y HRavg. The training doesn't equal the load supported and the distance performed in competition, so it is necessary to pay more attention during training. This information allows us to develop adequate training protocols adjusted to the specific individual requirements of the sports competition.
The objective of this study was to design and analyse the differences and/or similarities of two homogeneous intervention programmes (didactic units) based on two different teaching methods, Direct ...Instruction (DI) and Tactical Games Approach (TGA), for teaching school-age soccer. The sample was composed of 58 tasks, 29 for each intervention programme. The pedagogical and external Training Load (eTL) variables recorded in the Integral System for Training Tasks Analysis (SIATE) were studied. The two intervention programmes were compared using Chi-Square, Mann-Whitney U and the Adjusted Standardized Residuals statistical tests. Likewise, the strength of association of the variables under study was calculated using
and
coefficients. Both intervention programmes had the same number of tasks (
= 29), sessions (
= 12), game phases (
= 0.000;
= 1.000), specific contents (
² = 5.311;
= 0.968) and didactic objectives, as well as different levels of eTL (
= 145.000;
= 0.000;
= 1.357); which are necessary requirements to be considered similar. The differences and/or similarities between both intervention programmes will offer teachers guidelines to develop different didactic units using the specific DI and TGA methodologies.
The objective was to analyze the effectiveness in men’s and women’s professional padel of errors and winners depending on the type of shot and the importance of the situation during each game. In ...addition, differences between men and women were identified. The sample was made up of 2759 points corresponding to the games that finished with a golden point from matches played in the 2021 season of the World Padel Tour circuit. The results show men and women make more errors (men: 58.7%; women: 63.2%) than winners (men: 41.3%; women: 36.8%), and this difference increases as the importance of the points increases in men’s padel; however, the opposite happens in women’s padel. Trays and smashes are the most characteristic last shots in men’s and women’s padel (hits with which more winners are achieved), followed by back wall shots (shots where more errors are made) and then drive and backhand volleys. In men’s padel there are more winning shots and fewer errors than in women’s padel, except in the golden points, where men make more errors than women. These considerations are of great importance, as they help the players to know the most effective way to finish points according to the situation of the game.
Coaches’ player substitution strategies can change the tactical behavior and the final result of matches. This empirical study aims to describe the relationship/association of player substitution ...variables with the results of men’s UEFA Champions League matches during the 2018–2019 season. A total of 125 matches were analyzed using an ad hoc observation sheet created for this purpose. To measure the degree and strength of association between the variables studied, Chi-square and Cramer’s V tests were used, respectively. In turn, the Adjusted Standardized Residuals from the contingency tables were calculated to detect patterns of association. Likewise, a decision tree, in particular, the CHAID method, was used to predict and identify interactions. Player substitutions affect the final result and the findings prove it. An own team’s goal after 5–10 minutes of player substitution was win-related (positive impact) (90.40%, ASRs = 10.40), while an opposing team’s goal after 5–10 minutes of player substitution was loss-related (negative impact) (90.30%, ASRs = 10.30). Regardless of the match status, the positive impact increased the winning percentage. Furthermore, the match status was postulated as an indicator of the need to make player substitutions. It showed that player substitutions could determine the final result when teams were tying. On the other hand, the match location was not a differentiating factor between winning and losing teams, although the winning percentage was somewhat higher for home teams. Coaches could use this information to establish player substitution strategies that would allow them to perform at their best.
An understanding of basketball physical demands during official matches is fundamental for designing specific training, tactical, and strategic plans as well as recovery methods during congested ...fixture periods. Such assessments can be performed using wearable indoor time motion tracking systems. The purpose of this study was to analyze the time-motion profile of under 18-years of age (U'18) basketball players and compare their physical demands in relation to team ranking, playing position, match periods and consecutive matches during a 7-day tournament. Relative Distance (RD), percentage of High-Intensity Running (%HIR), Player Load (PL), Acceleration (Acc), Deceleration (Dec), Peak Speed (PSpeed), and Peak Acceleration (PAcc) were recorded from 94 players (13 centers, 47 forwards, and 34 guards) belonging to eight elite teams (age: 17.6 ± 0.8 years; height: 1.91 ± 0.08 m; body mass: 82.5 ± 8.8 kg). WIMU PRO
inertial measurement units with ultra-wide band (UWB) indoor-tracking technology recorded 13 matches during the
in the 2016-2017 season. Paired
-tests and one-way analyses of variance with omega partial squared (
) and Cohen's effect sizes (
) were used to analyze for differences between variables. According to team quality, the best teams had lower RD (
= 0.04;
= -0.14). Guards presented higher RD (
< 0.01;
= 0.03), PSpeed (
< 0.01;
= 0.01) and PAcc (
< 0.01;
= 0.02) compared to forwards and centers. The first quarter showed differences with higher RD (
< 0.01;
= 0.03), %HIR (
< 0.01;
= 0.02), and PL (
< 0.01;
= 0.04) compared to all other quarters. The third match of the tournament presented higher demands in RD (
< 0.01;
= 0.03), HIR (
< 0.01;
= 0.01) and PL (
< 0.01;
= 0.02) compared with the first two matches. This study showed that team quality, playing position, match period, and consecutive matches throughout an U'18 basketball tournament influenced the kinematic demands experienced by players during official competition. Therefore, each of these contextual factors should be considered in managing the load and developing individualized strategies for players in tournament settings.
