DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p362 The aim of this study was to verify the influence of the technical skills level on the decision making of novice volleyball players on service, reception and set actions. The sample was composed of 80 novice athletes of school volleyball teams of both sexes. Based on the results from the Volleyball Skills Test Battery, the sample was divided into three groups: low, intermediate and high technical level, by means of One-Way ANOVA. The intermediate group was excluded from further analyses. Decision making was assessed with the Game Performance Assessment Instrument (GPAI). For data analysis purposes, the independent student-t test was used, adopting significance level of p≤0.05. The results showed that players with low skill level in service and set actions also had lower performance on the decision-making test when compared to players with high technical level. On the other hand, in the reception action, no differences were found among groups. It was therefore concluded that the technical level seems to influence the decision making in service and set actions in novice volleyball players.

El objetivo del estudio fue analizar el efecto de manipulación de diferentes condicionantes de la tarea sobre la toma de decisiones y la eficacia de la acción de ataque en voleibol. Se planteó un diseño pre-experimental en el que participaron 22 alumnos de Educación Física con una edad comprendida entre los 12 y 13 años. La variable independiente fue un programa de intervención aplicado durante las 9 sesiones de una Unidad Didáctica, la cual fue diseñada en base a los principios metodológicos de la pedagogía no lineal, centrándose fundamentalmente en manipular condicionantes de la tarea, tales como, espacio de juego, altura de la red y número de participantes. Las variables dependientes fueron la toma de decisiones y la eficacia en la acción de ataque. Ambas variables fueron evaluadas a partir de la observación sistemática, utilizando el “Game Performance Assesment Instrument” (GPAI) (Oslin, Mitchell, & Griffin, 1998) para la toma de decisiones y el “Team Sports Assesment Procedure” (TSAP) (Gréhaigne et al., 1997) para la eficacia de la acción de ataque. Los resultados del estudio determinaron que todos los participantes manifestaron una mejora significativa, tanto en la toma de decisiones como en la eficacia entre la medida pre-test y pos-test. Respecto a estos resultados, el profesor de Educación Física, con el propósito de hacer progresar a los alumnos en su competencia táctica, debe diseñar tareas motrices que sean representativas del juego real y cuya complejidad táctica sea adaptada al nivel de aprendizaje de los discentes.Abstract. The aim of the study was to analyze the effect of manipulating different task constraints, such as play space, net height and number of participants on decision-making and efficacy in the attack action in volleyball. A pre-experimental design, in which 22 students aged between 12 and 13 years participated, was implemented. The independent variable was an intervention program applied during the 9 sessions of a teaching unit, which was designed based on the methodological principles of nonlinear pedagogy, focusing primarily on manipulating the different task constraints referred to above. The dependent variables were the decision-making and the efficacy in the attack action. Both variables were evaluated through the systematic observation of the game action, using the Game Performance Assessment Instrument (GPAI; Oslin, Mitchell, & Griffin, 1998) for decision-making and the Team Sports Assessment Procedure (TSAP; Gréhaigne et al., 1997) for the efficacy of the attack action. The results of the study showed that all participants improved both decision making and efficacy between the pre-test and post-test measures. Regarding these results, Physical Education teachers, with the purpose of advancing students in the tactical competence, should design tasks representative of the game and with a tactical complexity adapted to the learning level of the students.

Insight Into

Technical and Vocational Education and Training (TVET) colleges are intended to equip youths with work-relevant skills, but the capacity of the labour market to absorb them is limited and South Africa has high levels of unemployment. Employers argue that young work-seekers from TVET colleges may well possess technical skills but lack employability skills, including appropriate work-based attitudes and values. In response to this scenario, a team of experts designed a short, interactive programme for TVET college students to acquire an improved understanding of and insight into their own values and how these inform their behaviour in the workplace. The values selected were respect, accountability, self-improvement and perseverance. The programme’s intended outcome was to increase the participants’ awareness of the link between values and their actions so that they could improve their own decision-making and their relationships with colleagues in the workplace. Following this programme, the students were afforded a period of workplace exposure during which they were required to reflect on their experience and how workplace behaviour revealed their own and work colleagues’ underlying values. A crucial challenge for the project team was to be able to measure any impact on the participants’ understanding of the values and how this understanding might guide their behaviour. The focus of this article is on how the assessment instrument was conceptualised, designed and piloted in South Africa and Kenya. The instrument was required to measure effectively any changes in the participants’ understanding of the meaning of each value and the adjustments in their ability to apply the values in real work-based scenarios.

Purpose: To compare the tactical-technical behavior of volleyball players according to the manipulation of court size in small-sided games. Method: We analyzed the tactical-technical behaviors of 16 male players (12.2  ±  0.5 years and 1.2  ±  0.8 years of practice) using the components of the GPAI instrument (Adjustment, efficiency, decision-making and effectiveness) validated for volleyball. To this end, we examined 1614 transition actions (defense, setting and attack) from games played in four court dimensions (3.0 × 3.0m, 4.0 × 4.0m, 4.6 × 4.6m and 5.2 × 5.2m). Altogether 96 Volleyball games were analyzed. Results: The smaller area per player favored technical skills development, specifically defensive and offensive ones. On the other hand, a larger area per player promoted higher scores in decision-making and effectiveness. Conclusion: Our findings indicate that the players’ behaviors in small-sided games depend on the game configurations, since modifications in the tactical-technical behavior emanate from the game ecology. Thus, the court size manipulation is a powerful pedagogical tool that deeply relates to learning outcomes. Coaches must consider such constraints in the teaching-learning process, since small-sided games manipulations should be linked with clear learning goals.

ABSTRACT Introduction: Peripheral nerve adaptation is critical for strength gains. However, information about intensity effects on nerve morphology is scarce. Objective: To compare the effects of different intensities of resistance training on radial nerve structures. Methods: Rats were divided into three groups: control (GC), training with 50% (GF1) and training 75% (GF2) of the animal’s body weight. The morphological analysis of the nerve was done by light and transmission electron microscopy. One-way ANOVA and the Tukey’s post hoc test were applied and the significance level was set at p≤0.05. Results: Training groups had an increase of strength compared to GC (p≤0.05). All measured nerve components (mean area and diameter of myelin fibers and axons, mean area and thickness of the myelin sheath, and of neurofilaments and microtubules) were higher in GF2 compared to the other (p≤0.05). Conclusion: Results demonstrated greater morphological changes on radial nerve after heavier loads. This can be important for rehabilitation therapies, training, and progression.

Abstract It is not known if competitive anxiety affects decision-making performance in athletes. This study aimed to analyze the effect of competitive anxiety on passing decision-making in young soccer players. This is a prospective study, whose sample consisted of 40 soccer athletes of the under-17 category. The Portuguese version of the Competitive State Anxiety Inventory (CSAI-2R) was filled out by athletes 45 minutes before the start of a soccer match. Decision-making was evaluated in a real game situation. The analysis and categorization of actions were based on the Game Performance Assessment Instrument. The results showed significant influence of cognitive anxiety (R² =.20; p = .001), somatic anxiety (R² = .45; p = .001) and self-confidence about the passing decision-making index (R² = .31; p = .001). It was concluded that competitive anxiety can be considered an intervening factor in decision-making of the pass of young male soccer players.Keywords: test validity, scaling, elderly, depression

Abstract. The Game Performance Evaluation Tool (GPET) is an instrument that allows us to obtain information about the student's decision-making process during their participation in games. The usual instruments reflect the final result of student's decision. However, the GPET offers an analysis of the context in which the decision has been made, and allows teachers to establish a certain degree of quality in the decision taken. Thus, the GPET helps us to distinguish in the decision-making process, not only "what has been done" from "what should have been done" in a specific game situation (Gutiérrez, González, García-López, Mitchell, 2011), but also it gives us information about the player's adaptation to the tactical context in which he/she is involved during game play. According Godbout (1990), this adaptation to the tactical context describes the decisional process, rather than the result. Given that the GPET is an instrument initially designed for research, in this article we present how to take advantage of the GPET novelties, applying them in an instrument with a clear teaching orientation, such as the Game Performance Assessment Instrument (GPAI) (Mitchell, Oslin and Griffin, 2013).Resumen. El Game Performance Evaluation Tool (GPET, en español Herramienta de Evaluación del Rendimiento de Juego), es un instrumento que nos permite obtener información sobre el proceso de toma de decisiones del alumno durante su participación en los juegos deportivos. Los instrumentos habituales reflejan el resultado final de la decisión del alumno. Sin embargo, el GPET hace un análisis del contexto en el que se ha tomado la decisión, y permite que el docente pueda establecer cierta gradación en la calidad de la decisión tomada. Así, el GPET nos ayuda a distinguir en la toma de decisiones no sólo “qué se ha hecho” de “qué se debería haber hecho” en una situación concreta de juego (Gutiérrrez, González, García-López, Mitchell, 2011), sino también nos aporta información de la adaptación del jugador al contexto táctico en el que se encuentra. Dicha adaptación, de acuerdo con Godbout (1990), nos describe el proceso decisional, más que el resultado. En este artículo presentamos como aprovechar las novedades del GPET, que es un instrumento inicialmente diseñado para el ámbito de la investigación, aplicándolas en un instrumento con una orientación claramente docente, como es el Game Performance Assessment Instrument (GPAI, en español Instrumento de Evaluación del Rendimiento de Juego, de Mitchell, Oslin y Griffin, 2013).

Decision-making (DM) is an important ability targeted in the formation of young football players that can improve by using small-sided games (SSGs). The main purpose of this study was to assess players’ DM in different balanced and unbalanced SSG formats keeping the play area constant. The sample was composed of 10 field players plus 2 goalkeepers (13.55±0.51 years). This study consisted of 3 sessions, one day for each session, with an interval of 48 hours apart between sessions. Three different SSG formats (4vs.4; 4vs.5; 4vs.6), in a play area of 40x30 meters, were selected. The outcome was the decision-making index (DMI), assessed with the Game Performance Assessment Instrument (GPAI). Results showed that on two of the three days, there were statistical differences in DMI across the three different SSG formats. In the 4vs.6 format a higher median score than in the 4vs.4 format was recorded on day 2 (U=13.0, z=-2.34, p=.025, r=.57) and day 3 (U=5.50, z=-2.98, p=.003, r=.72). In conclusion, the use of unbalanced SSG formats in the training may benefit DM development, and therefore may constitute an important factor to be considered in the formation of young football players.

OBJECTIVES This study examined the development of Chinese pre-service physical education teachers’ technical skill, tactical understanding, game performance (common content knowledge - CCK), and specialized content knowledge (SCK) during a badminton course incorporating Play Practice instruction.METHODS Participants were 36 pre-service teachers (31 males, 5 females: age 21 ± 1.0) majoring in physical education at a university in central China. The students completed a 24 lesson course after a 16 weeks semester. A typical lesson (90 minutes) included a 10-minute warm-up, followed by instruction in two or three technical skills or tactics for 50-55 minutes. The final 25-minutes included the Play Practice aspect of the lesson - a specific game-based challenge to reinforce a technical or tactical aspect of badminton play. The challenge included the three typical pedagogies of Play Practice: focusing, shaping, and enhancing. The French clear test, tactical understanding in badminton, Game Performance Assessment Instrument (GPAI), and student-generated content maps were used to respectively monitor changes in technical skills, tactical understanding, game performance, and specialized content knowledge before and after the course. Parametric statistics were used to compare student outcomes.RESULTS Statistically significant differences were found on all measures from pre- to post-test, with all showing large effect sizes. In particular, over 75% of students achieved the benchmark depth of SCK following the course.CONCLUSIONS The inclusion of Play Practice within a sport instruction course can contribute to various elements that are needed to promote the CCK and SCK of pre-service physical education students.

The objective of this study was to identify how the ecological variables influence the setter during the setting and what were the predictive factors of the attack effect among Brazilian teams ranked from the 1st to 4th place in the volleyball Women’s Super-League in 2016-2017. We analyzed 768 attacks from 10 matches played among the teams. A descriptive analysis was performed and, to identify how the setting location differed in relation to the ecological variables, the One-Way ANOVA (factor 1 = setting location) was used. In addition, multinomial logistic regression was performed to understand the predictive factors of the effect of the attack. The significance level was set at 5% (p≤.05) and the SPSS software version 20.0 was used. The results showed the setting location differed according to the distance between the setter and the central attacker, the distance between the setter and the central blocker, and the distance between the setter and the blocker of position 4. Besides, it was observed that the powerful attack and the blocking touch were predictive factors of the effect of the attack. Thus, it is concluded that the decision-making for the action of the setting is based on the availability of the central attacker and the configuration of the blockers, the powerful attack reduces the chances of defense and the blocking touch reduces the chances of scoring by attacking.
