Predicting Quality of Life in Women with Breast Cancer Who Engage in Physical Exercise: The Role of Psychological Variables.

In this study, we aimed to conduct a descriptive analysis of the primary physiological and psychological factors influencing the quality of life in women with breast cancer who engage in physical exercise. The study examined the key psychological variables predicting patients' quality of life, perceived support from family and friends, and the perception of physical condition. The sample consisted of 46 women from Cáceres (Spain) aged between 30 and 75 years undergoing breast cancer treatment. The Functional Evaluation Scale in Cancer Therapy (FACT-B+4) was used to measure quality of life; the Basic Psychological Needs Satisfaction Scale was used to measure autonomy, competence, and social relationships; the Behavior Regulation Questionnaire in Exercise (BREQ-3) was used to measure the types of self-determined motivation for sports participation; the General Evaluation of Self-Esteem Scale was used to measure self-esteem; the International Fitness Scale (IFIS) was used to measure perceived physical condition; and the Perceived Autonomy Support Scale for Exercise Settings (PASSES) was used to measure the perceived autonomy support from family and friends. A multiple regression analysis revealed that perceived physical condition and self-esteem were significant positive predictors of a variance in quality of life, while intrinsic motivation did not significantly predict it. The findings underscore the importance of promoting autonomous motivation in patients to enhance their physical and psychological well-being through physical activity.

Using the Conceptual Framework for Examining Sport Teams to Understand Group Dynamics in Professional Soccer.

(1) Background: The aim of this study is to propose a model of the interactions of group dynamics using the conceptual framework to examine sports teams; (2) Methods: The hypothesized model includes measures of group structure (authentic leadership, perceived justice, coaching competency, role clarity/ambiguity, and role conflict), group cohesion (cohesion and team conflict), and group processes (collective efficacy and transactive memory systems). Participants were 581 professional soccer players (M = 24.51, SD = 3.73; 356 males and 225 females) who completed a multisection questionnaire assessing group dynamics variables; (3) Results: The results show that coach leadership predicts coaching competency and perceived justice, and both competency and justice predict role ambiguity and role conflict. Furthermore, role ambiguity and role conflict predict group cohesion and team conflict, whereas group cohesion and team conflict both predict the transactive memory system. Finally, collective efficacy is predicted by the transactive memory system; (4) Conclusions: The results suggest the importance of coach behavior (leadership, justice, and competency) and group processes to improving team functioning in a professional sports context.

Análisis diferencial de variables psicológicas relacionadas con el compromiso para la práctica deportiva en universitarios durante el confinamiento por la COVID-19 / Differential Analysis of Psychological Variables Related to the Commitment to Sport Practice in University Students During Confinement by COVID-19

En la actualidad los componentes psicológicos han alcanzado una importancia muy notable en la adquisición de comportamientos saludables. Por lo tanto, este estudio analiza las diferencias entre variables psicológicas que se relacionan con la práctica deportiva en estudiantes universitarios durante el confinamiento causado por la COVID-19. El estudio tuvo una muestra de 1239 participantes (765 varones y 474 mujeres), de edades comprendidas entre los 16 y 45 años (M = 21,44; DT = 3,94). Se utilizó un cuestionario que incluyó la Behavioral Regulation in Sport Questionnaire (BRSQ), la Escala de las Necesidades Psicológicas Básicas en el Ejercicio; la Escala de Autoeficacia para la Actividad Física; y la Escala de Grado de Compromiso Deportivo. Los resultados más relevantes muestran diferencias significativas (p<0,01) en favor del género masculino en casi todas las variables psicológicas excepto en la desmotivación, así mismo en lo que respecta a la motivación controlada y desmotivación, se encontraron diferencias significativas entre las localidades pequeñas y grandes, siendo los valores más altos en las primeras (p<0,05 y <0,01). Se discuten los resultados con objeto de determinar las diferencias en cuanto a qué componentes psicológicos permitirían plantear intervenciones que sean más efectivas para lograr la práctica regular de actividades deportivas así como su compromiso y adherencia, mediante el uso de estrategias que vayan encaminadas a fomentar la motivación autónoma de los universitarios y contrarrestar los efectos de la motivación controlada y la desmotivación.

Nowadays, psychological components have attained a very notable importance in the acquisition of healthy behaviours. Therefore, this study analyses the differences between psychological variables that are related to sports practice in university students during the confinement caused by COVID-19. The study had a sample of 1239 participants (765 males and 474 females), aged 16-45 years (M = 21.44, SD = 3.94). A questionnaire, which included the Behavioural Regulation in Sport Questionnaire (BRSQ), the Basic Psychological Needs in Exercise Scale; the Physical Activity Self-Efficacy Scale; and the Degree of Sport Commitment Scale, was used. The most relevant results show significant differences (p<0.01) in favour of the male gender in almost all psychological variables except demotivation. Likewise, with regard to controlled motivation and demotivation, significant differences were found between small and large localities, with higher values in the former (p<0.05 and <0.01). The results are discussed in order to determine the differences in terms of which psychological components would allow for interventions that might be more effective in achieving regular sport practice, commitment, and adherence through the use of strategies aimed at fostering autonomous motivation in university students and counteracting the effects of controlled motivation and demotivation.

Validity and Reliability of the Portuguese Version of the Healthy Lifestyle Questionnaire-EVS III.

The main objective of this study was to validate the Healthy Lifestyle Questionnaire-EVS III, using confirmatory factor analysis of the measurement model. A total of 822 Portuguese individuals of both genders, aged between 18 and 66 years old (M = 28.43 SD = 12.07), participated in this study, of which 382 were male (46.5%) and 440 were female (53.5%). The main results obtained revealed that the psychometric qualities prove the adequacy of the factor structure of the Healthy Lifestyles Questionnaire-EVS III (7 factors/32 items) and that it has acceptable validity indices: χ2 = 644.6828, p = 0.000, df = 168, χ2/df = 3.84, NFI = 0.901, TLI = 0.902, CFI = 0.921, IFI = 0.922, MFI = 0.900, GFI = 0.909, AGFI = 0.901, RMR = 0.073, SRMR = 0.059 and RMSEA = 0.059, enabling the assessment of factors related to a balanced diet, respect for mealtimes, tobacco consumption, alcohol consumption, consumption of other drugs, resting habits and physical activity habits. The Portuguese version of the Healthy Lifestyles Questionnaire-EVS III can be used with reasonable confidence for the assessment of healthy lifestyles.

Modification of the Forms of Self-Determined Regulation and Quality of Life after a Cardiac Rehabilitation Programme: Tennis-Based vs. Bicycle Ergometer-Based.

BACKGROUND: The objective is to analyse and compare the effects of an adapted tennis cardiac rehabilitation programme and a classical bicycle ergometer-based programme on the type of motivation towards sports practice and quality of life in patients classified as low risk after suffering acute coronary syndrome. METHODS: The Behavioural Regulation in Exercise Questionnaire (BREQ-2) and Velasco's Qualityof Life Test were applied. The sample comprised 110 individuals (age = 55.05 ± 9.27) divided into two experimental groups (tennis and bicycle ergometer) and a control group. RESULTS: The intra-group analysis showed a significant increase between pre- and post-test results in intrinsic regulation in the tennis group and in the control group. In identified regulation, the bicycle ergometer group presented significant differences from the control group. On the other hand, in the external regulation variable, only the tennis group showed significant differences, which decreased. Significant improvements in all quality-of-life factors when comparing the pre-test period with the post-test period were only found in the experimental groups. As per the inter-group analysis, significant differences were observed in favour of the tennis group with respect to the control group in the variables of health, social relations and leisure, and work time as well as in favour of the bicycle ergometer group compared with the control group in the variables of health, sleep and rest, future projects and mobility. No significant differences were found in any of the variables between the tennis group and the bicycle ergometer group. CONCLUSION: It is relevant to enhance the practice of physical exercise in infarcted patients classified as low risk as it improves the forms of more self-determined regulation towards sporting practice and their quality of life.

Psychometric Properties of the Healthy Lifestyle Questionnaire for Ecuadorian University Students (EVS-EUE).

University students are considered a key population in promoting and establishing healthy lifestyles that will ensure a full life for the next generations. The purpose of this study was to do a cultural and linguistic adaptation of the healthy lifestyle questionnaire for Ecuadorian university students (EVS-EUE). Two thousand, one hundred and eight (2108) students from 17 to 19 years old (27%), 20 to 24 years old (57%), and over 24 years old (16%) participated (M = 21.81 years; SD = 3.04). A confirmatory factor analysis, internal consistency analysis, and concurrent validity were conducted. The results of the EVS-EUE Questionnaire presented adequate values (χ2/d.f = 9.02, Comparative Fit Index (CFI) = 0.96, Incremental Fit Index (IFI) = 0.96, McDonald Fit Index (MFI) = 0.91, Adjusted Goodness of Fit Index (AGFI) = 0.94, Root Mean Square Error of Approximation (RMSEA) = 0.06, Standardized Root Mean Square Residual (SRMR) = 0.03). The internal consistency showed values above 0.70, and analyzed its concurrent validity, reaching adequate values. This study has provided a valid and reliable questionnaire to evaluate healthy lifestyles in the Ecuadorian population.

Fitbit wear-time and patterns of activity in cancer survivors throughout a physical activity intervention and follow-up: Exploratory analysis from a randomised controlled trial.

OBJECTIVE: There has been growing interest in the use of smart wearable technology to promote physical activity (PA) behaviour change. However, little is known concerning PA patterns throughout an intervention or engagement with trackers. The objective of the study was to explore patterns of Fitbit-measured PA and wear-time over 24-weeks and their relationship to changes in Actigraph-derived moderate-to-vigorous PA (MVPA). METHODS: Twenty-nine intervention participants (88%) from the wearable activity technology and action-planning (WATAAP) trial in colorectal and endometrial cancer survivors accepted a Fitbit friend request from the research team to permit monitoring of Fitbit activity. Daily steps and active minutes were recorded for each participant over the 12-week intervention and throughout the follow-up period to 24-weeks. Accelerometer (GT9X) derived MVPA was assessed at end of intervention (12-weeks) and end of follow-up (24-weeks). RESULTS: Fitbit wear-time over the 24-weeks of data was remarkably consistent, with median adherence score of 100% for all weeks. During the intervention, participants recorded a median 8006 steps/day. Daily step count was slightly increased through week-13 to week-24 with a median of 8191 steps/day (p = 0.039). Actigraph and Fitbit derived measures were highly correlated but demonstrated poor agreement overall. Fitbit measured activity was closest to MVPA measured using Freedson cut-points as no bias was observed. CONCLUSIONS: Step count was maintained throughout the trial displaying promise for the effectiveness of smart-wearable interventions to reduce sedentary behaviour beyond the intervention period. Further worthwhile work should compare more advanced smart-wearable technology with accelerometers in order to improve agreement and explore less resource-intensive methods to assess PA that could be scalable.

Validation of the Portuguese Version of the Healthy Lifestyle Questionnaire.

The main objective of this study was the validation of the Healthy Lifestyle Questionnaire (EVS II), using a confirmatory factorial analysis of the measurement model, with veteran athletes. A total of 348 veteran Portuguese athletes of both genders, aged between 30 and 60 years (M = 41.64, SD = 9.83), of whom 200 were males and 148 were females, from several sports. The results of the confirmatory factor analysis demonstrate the adequacy of the adapted version of the EVS II, as the factorial structure (6 factors/24 items) has acceptable validity indexes: χ2 = 305.925, p = 0.000, df = 120.017, χ2/df = 2.549, NFI (Normed Fit Index) = 0.909, TLI (Tucker Lewis Index) = 0.918, CFI (Comparative Fit Index) = 0.944, GFI (Goodness of Fit Index) = 0.944, AGFI (Adjusted Goodness of Fit Index) = 0.909, SRMR (Standardized Root Mean Square Residual) = 0.048, RMSEA (Root Mean Square of Approximation) = 0.060, allowing evaluation of the dimensions of balanced diet, respect for mealtime, tobacco and alcohol consumption, other drugs consumption and resting habits. The adaptation to sport of the Portuguese version of EVS II can be used with reasonable confidence in the evaluation of healthy lifestyles in the context of sport.

Motivation and Commitment to Sports Practice During the Lockdown Caused by Covid-19.

In Spain, the state of alarm declared on March 14, 2020 caused changes in the population in relation to the habits of physical activity and sports practice. This study analyzed what motivational variables predicted the self-efficacy and commitment to sports practice, as well as the differences according to gender, during lockdown and the progressive de-escalation caused by COVID-19, using the theory of self-determination as a theoretical framework. The study sample was conformed of 179 subjects (90 men and 89 women) between 18 and 65 years of age (M = 28.64; SD = 10.28). The Behavioral Regulation in Sport Questionnaire (BRSQ), the Psychological Need Satisfaction in Exercise Scale (PNSE), the Physical Activity Self-Efficacy scale, and the Sport Commitment scale were applied. The most relevant results have showed significant differences in favor of the male gender in terms of levels of controlled motivation and amotivation, as well as higher levels of self-efficacy and basic psychological need of autonomy. Furthermore, the regression analysis has revealed that self-efficacy and current commitment to sports practice were explained by a variance of 57 and 64%, respectively, due to autonomous motivation and the basic psychological need of competence. Therefore, the basic psychological need of competence should be fostered in order to increase the levels of self-determined motivation, self-efficacy, and commitment to sports practice of the population.

Impact of Weekly Physical Activity on Stress Response: An Experimental Study.

The aim of this research is focused on analyzing the alteration of the psychophysiological and cognitive response to an objective computerized stress test (Determination Test - DT-, Vienna test System®), when the behavioral response is controlled. The sample used was sports science students (N = 22), with a mean age of 22.82 (Mage = 22.82; SD years = 3.67; MPhysicalActivity hours/Week = 7.77; SD hours/week = 3.32) A quasi-experimental design was used in which the response of each participant to the DT test was evaluated. The variable "number of hours of physical activity per week" and the variable "level of behavioral response to stress" were controlled. Before and after this test, the following parameters were measured: activation and central fatigue (Critical Flicker Fusion Threshold (CFF Critical flicker fusion ascending and Critical flicker fusion descending; DC potential), and perceived exertion (Central Rating of Perceived Exertion and Peripheral Rating of Perceived Exertion). Significant differences were found in all of the measures indicated. The usefulness of this protocol and the measures used to analyze the stress response capacity of the study subjects are discussed.

The importance of assigning responsibility during evaluation in order to increase student satisfaction from physical education classes: A structural equation model.

Considering the benefits that students report when evaluating physical education classes, the purpose of the present study was to analyse the relationships between the assignment of student responsibility in the evaluation, motivational variables and the satisfaction with the physical education classes, using The Theory of Self-determination as a support method. The sample for this study was 922 students, of both genres and in Compulsory Secondary Education, aged between 14 and 18 years. To carry out the study, the Student's Scale of Responsibility was used in the physical education assessment, the Basic Psychological Needs Measuring Scale, the Percentage Scale for Physical Education Causality and the Satisfaction Scale in Physical Education. The results of the structural equations model revealed a good adjustment to the data. This finding highlights the importance of giving responsibilities to the students in the evaluation process, in order to satisfy the psychological needs of the students and, therefore, self-determined motivation. Additionally, the satisfaction of psychological needs and self-determined motivation increase satisfaction towards physical education classes.

Promoting physical activity in regional and remote cancer survivors (PPARCS) using wearables and health coaching: randomised controlled trial protocol.

INTRODUCTION: Physically active cancer survivors have substantially less cancer recurrence and improved survival compared with those who are inactive. However, the majority of survivors (70%-90%) are not meeting the physical activity (PA) guidelines. There are also significant geographic inequalities in cancer survival with poorer survival rates for the third of Australians who live in non-metropolitan areas compared with those living in major cities. The primary objective of the trial is to increase moderate-to-vigorous PA (MVPA) among cancer survivors living in regional and remote Western Australia. Secondary objectives are to reduce sedentary behaviour and in conjunction with increased PA, improve quality of life (QoL) in non-metropolitan survivors. Tertiary objectives are to assess the effectiveness of the health action process approach (HAPA) model variables, on which the intervention is based, to predict change in MVPA. METHODS AND ANALYSIS: Eighty-six cancer survivors will be randomised into either the intervention or control group. Intervention group participants will receive a Fitbit and up to six telephone health-coaching sessions. MVPA (using Actigraph), QoL and psychological variables (based on the HAPA model via questionnaire) will be assessed at baseline, 12 weeks (end of intervention) and 24 weeks (end of follow-up). A general linear mixed model will be used to assess the effectiveness of the intervention. ETHICS AND DISSEMINATION: Ethics approval has been obtained from St John of God Hospital Subiaco (HREC/#1201). We plan to submit a manuscript of the results to a peer-reviewed journal. Results will be presented at conferences, community and consumer forums and hospital research conferences. TRIAL REGISTRATION NUMBER: ACTRN12618001743257; pre-results, U1111-1222-5698.

A randomized controlled trial of WATAAP to promote physical activity in colorectal and endometrial cancer survivors.

OBJECTIVE: The objective of this study was to ascertain whether wearable technology coupled with action planning was effective in increasing physical activity (PA) in colorectal and endometrial cancer survivors at cardiovascular risk. METHODS: Sixty-eight survivors who had cardiovascular risk factors and were insufficiently active were randomized to intervention and control arms. Intervention participants were given a wearable tracker for 12 weeks, two group sessions, and a support phone call. Participants in the control arm received print materials describing PA guidelines. Assessments at baseline and 12 weeks measured triaxial and uniaxial estimates of moderate-vigorous physical activity (MVPA), sedentary behaviour, blood pressure, and body mass index (BMI). RESULTS: The intervention group significantly increased MVPA by 45 min/wk compared with a reduction of 21 min/wk in the control group. Group by time interactions were significant for minutes of MVPA (F1,126  = 5.14, P = 0.025). For those with diastolic hypertension, there was a significant group by time interaction (F1,66  = 4.89, P = 0.031) with a net reduction of 9.89 mm Hg in the intervention group. CONCLUSIONS: Significant improvements in MVPA were observed following the intervention. The results display promise for the use of pragmatic, low-intensity interventions using wearable technology.

Wearable Activity Technology And Action-Planning (WATAAP) to promote physical activity in cancer survivors: Randomised controlled trial protocol.

Background/Objective: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity. The Health Action Process Approach (HAPA) is a promising theoretical framework for health behaviour change, and wearable physical activity trackers offer a novel means of self-monitoring physical activity for cancer survivors. Method: Sixty-eight survivors of colorectal and gynecologic cancer will be randomised into 12-week intervention and control groups. Intervention group participants will receive: a Fitbit Alta™ to monitor physical activity, HAPA-based group sessions, booklet, and support phone-call. Participants in the control group will only receive the HAPA-based booklet. Physical activity (using accelerometers), blood pressure, BMI, and HAPA constructs will be assessed at baseline, 12-weeks (post-intervention) and 24-weeks (follow-up). Data analysis will use the Group x Time interaction from a General Linear Mixed Model analysis. Conclusions: Physical activity interventions that are acceptable and have robust theoretical underpinnings show promise for improving the health of cancer survivors.

Antecedentes/Objetivo: Los sobrevivientes de cáncer tienen riesgo cardiovascular debido a la comorbilidad y al comportamiento sedentario, lo que justifica desarrollar una adecuada intervención para aumentar la práctica de actividad física. El Enfoque del Proceso de Acción de Salud (EPAS) constituye un marco teórico para el desarrollo de conductas saludables y los dispositivos electrónicos de actividad física son nuevas herramientas de automonitorización para los supervivientes de cáncer. Método: Sesenta y ocho sobrevivientes de cáncer colorrectal y ginecológico serán aleatorizados en grupos de intervención y control. Los participantes del grupo de intervención recibirán un Fitbit Alta™ para monitorizar la actividad física, sesiones grupales y aplicación de un folleto de EPAS, y una llamada telefónica de apoyo. Los participantes del grupo control únicamente recibirán un folleto basado en EPAS. Al inicio del estudio, a las 12 y 24 semanas, se evaluarán la actividad física (usando acelerómetros), la presión arterial, el Índice de Masa Corporal (IMC) y los constructos EPAS. El análisis de datos utilizará la interacción Grupo x Tiempo a partir de un análisis del Modelo Mixto Lineal General. Conclusiones: Las intervenciones de actividad física son factibles y tienen fundamentos teóricos que auguran mejorar la salud de los sobrevivientes de cáncer.

Validación al castellano de la escala sobre competencia del entrenador / Validação em castelhano da escala sobre competência do treinador / Validation into Spanish of the athletes’ perceptions of coaching competency scale

El objetivo del estudio fue realizar una validación al castellano de la escala desarrollada por Myers, Chase, Beauchamp, y Jackson (2010) sobre la competencia del entrenador (Athletes’ Perceptions of Coaching Competency Scale II-High School Teams: APCCS II-HST). La muestra del estudio estuvo formada por 581 jugadores, de los cuales 356 jugadores eran de género masculino y 225 de género femenino, con edades comprendidas entre los 18 y los 39 años (M = 24.51; DT = 3.73). Tras analizar diferentes modelos de medida, los resultados indican que la estructura Exploratory Structural Equation Modeling (ESEM) de primer orden es la que mejor se ajusta a los datos, mostrando además correlaciones entre factores más bajas. Además, la escala mostró una adecuada consistencia interna y validez concurrente a través de las relaciones con la satisfacción con el entrenador, y se mostró invariante para jugadores de ambos géneros. De esta manera, los entrenadores y psicólogos deportivos podrían utilizar esta escala para medir cada una de las dimensiones del instrumento de competencia del entrenador en deportistas de alto rendimiento (AU)

The aim of the study was to develop a validation into Spanish of the of the scale carried out by Myers, Chase, Beauchamp, and Jackson (2010) about coach’ competence (Athletes’ Perceptions of Coaching Competency Scale II-High School Teams: APCCS II-HST). The sample was formed by 581 players, whom 356 athletes were male and 225 individuals were female, ranging in age from 18 to 39 years old (M = 24.51; SD = 3.73). After analyzing different measurement models, the results indicate that Exploratory Structural Equation Modeling (ESEM) structure the first-order is the best fit for the data, showing correlations lower between factors. In addition, the scale showed adequate internal consistency and concurrent validity through relationships with coach satisfaction, and was shown to be invariant for players of both genders. Thus, coaches and sport psychologists might use this scale to measure each of the instruments’ dimensions of coaching competency in high performance athletes (AU)

Motivación y estadios de cambio para el ejercicio físico en adolescentes / Motivation and stages of change for physical exercise in adolescents

Resulta primordial que los adolescentes adquieran un estilo de vida activo; por ello, el objetivo de este estudio fue averiguar qué variables de la Teoría de Metas de Logro y del Modelo Jerárquico de la Motivación predecían los estadios de cambio para el ejercicio físico del Modelo Transteórico. Para ello, se empleó un diseño de investigación descriptivo transversal, con una muestra de 359 estudiantes de segundo ciclo de ESO y primero de Bachillerato, que respondieron el Cuestionario de Orientación al Aprendizaje y al Rendimiento en las Clases de Educación Física (LAPOPECQ), la Escala de Motivación Educativa (EME), la Escala de medición de las Necesidades Psicológicas Básicas (BPNES) y el Cuestionario de Estadios de Cambio para el ejercicio físico - Medida continua (URICA-E2), y se realizaron los análisis factorial exploratorio, confirmatorio, de fiabilidad, descriptivo y de regresión. Los resultados más relevantes mostraron que el estadio de precontemplación fue predicho negativamente por la competencia y positivamente por la desmotivación y la percepción del clima motivacional que implica al ego; el estadio de contemplación-preparación fue predicho positivamente por la competencia y la motivación intrínseca-perfección, la motivación extrínseca-introyectada, y negativamente por la autonomía; y el estadio de acción-mantenimiento fue predicho positivamente por la competencia. Estos resultados sugieren que la necesidad psicológica básica de competencia es la variable más relevante para adherirse a los estadios de práctica de ejercicio físico más activos.

It is essential for adolescents to acquire an active lifestyle. Therefore, the purpose of this study was to determine which variables of Achievement Goal Theory and the Hierarchical Model of Motivation predicted the change stages for exercise in the Transtheoretical Model. To this effect, a descriptive and cross-section study was carried out with 359 secondary school and undergraduate students. The Learning and Performance Orientations in Physical Education Classes Questionnaire (LAPOPECQ), Academic Motivation Scale (AMS), Basic Psychological Needs Scale (BPNES), and Stages of Change in Exercise - Continuous Measure (URICA-E2) were applied. Exploratory and confirmatory factorial, reliability, descriptive and regression analyses were subsequently conducted. The most relevant results showed that the Pre-contemplation Stage was predicted negatively by Competence, and positively by Amotivation and perception of ego-involving environment. The Contemplation-Preparation Stage was predicted positively by competence and Perfection Intrinsic Motivation - Introjected Extrinsic Motivation and negatively by autonomy. The Action-Maintenance Stage was positively predicted by competence. These results suggesting that basic psychological need of competence is the most relevant variable for the engagement to the more active stages of physical activity.

Motivación, conocimiento y toma de decisiones: Un estudio predictivo del éxito en voleibol / Motivation, knowledge and decision-making: a predictive study of performance in volleyball

Los objetivos de esta investigación fueron, desde la Teoría de la Autodeterminación, profundizar en la relación entre diferentes variables cognitivas y motivacionales que afectan al rendimiento de jugadores de voleibol en etapas de formación y determinar el nivel de predicción de éstas sobre el rendimiento. La muestra de estudio estuvo compuesta por 134 jugadores de voleibol de categoría cadete. Las variables de estudio fueron: motivacionales (necesidades psicológicas básicas y motivación), cognitivas (conocimiento y toma de decisiones), y de éxito en juego (rendimiento). Los resultados mostraron la existencia de relación entre las variables cognitivas y motivacionales. Específicamente, el conocimiento procedimental se asoció con la motivación intrínseca, la desmotivación y con las necesidades psicológicas básicas de relaciones sociales y competencia. Las variables cognitivas actuaron como principales predictoras del rendimiento. Por consiguiente, se propone la intervención conjunta en la mejora de las destrezas cognitivas y motivacionales, en voleibol en etapas de formación, como un aspecto de gran relevancia para la mejora del jugador en su proceso de formación deportiva

The aims of this research were, based on Self Determination Theory, to go further into the relationship between different cognitive and motivational variables that affect players’ performance in training stages and to know their predictive power on performance. The study sample was composed of 134 U-16 volleyball players. The studied variables were: motivational (motivation and basic psychological needs), cognitive (procedural knowledge and decision making), and performance. The results showed a relationship between motivational and cognitive variables. Specifically, procedural knowledge correlated positively with intrinsic motivation and basic psychological needs of relatedness and competence and negatively with amotivation. Cognitive variables were the main predictors of players’ performance. Intervention is suggested in order to improve cognitive processes due to their relevance in performance in volleyball training stages, taking into account motivational skills because of their relevance in players’formative process
