Alterações dos estados de ânimo presentes de jovens atletas de futebol em função do decurso temporal durante um período competitivo / Youth soccer players mood changes in function of time course during a competitive season.

Ricardo Marinho de Mello de Picoli 29 February 2016 (has links)
São escassos os estudos que analisam o contínuo temporal dos estados de ânimo ao longo de um período competitivo esportivo. Embora os estados de ânimo pareçam estáveis ao longo do tempo, diferentes estímulos e contextos presentes modificam a intensidade e a valência desses estados. Além disso, há fenômenos psicológicos como decaimento, em que traços de informação perdem sua ativação devido, principalmente, à passagem do tempo e a expectativa, que é a espera pela ocorrência de um evento em um determinado tempo. O objetivo desse estudo foi examinar as alterações dos estados de ânimo em jovens atletas de futebol, separados por posição e função, que ocorreram num período competitivo, em função do decurso temporal. Assim, processos como decaimento dos estados de ânimo e a influência da expectativa pela ocorrência jogo foram analisados, bem como a influência do contexto nas variações dos estados de ânimo dos atletas. Participaram deste estudo 18 jovens atletas (média de 15,4 anos ± 0,266) de um clube de futebol que estava disputando um campeonato estadual. Para o acesso aos estados de ânimo, foi utilizada a versão reduzida da Lista de Estados de Ânimo Presentes (LEAP), juntamente com um formulário de instruções de preenchimento, aplicada minutos antes de alguns treinamentos e jogos. Foram calculados os valores de presença de cada Fator da LEAP em cada evento para cada participante. Os dados foram coletados em três tipos de Eventos: antes do último treino antecedente ao jogo (Treino-Pré), antes do jogo (Pré-jogo) e antes do primeiro treino subsequente ao jogo (Treino-Pós). Os 18 jogadores foram divididos em dois grupos: Ações Defensivas (AD) e Ações Ofensivas (AO). Foram encontrados padrões de alteração dos estados de ânimo, representados pelos Fatores II (Fadiga), VII (Interesse) e XII (Serenidade) da LEAP, em função do decurso temporal, permitindo a análise dos processos de decaimento desses estados de ânimo e a influência da expectativa nessas alterações. Também foi encontrado que alguns estados de ânimo diferiram seus padrões de alteração de acordo com um intervalo temporal (Fatores IV Limerência/Empatia e; VII Interesse), bem como tiveram valores de presença diferentes na comparação entre esses intervalos. Além disso, os Fatores III (Esperança), V (Fisiológico) e XI (Receptividade) apresentaram padrões de alteração em função do decurso temporal em diferentes intervalos temporais. Variáveis contextuais, como o resultado das partidas e a competição esportiva em si, também foram influentes nessas alterações. Fadiga, esperança, empatia, estados ligados à propriocepção, interesse, receptividade e serenidade foram os estados de ânimo presentes durante todo o estudo. Ressalta-se a importância de incluir a temporalidade como variável influente nos modelos de variação de processos neurobiológicos, sobretudo nas investigações acerca de aspectos subjetivos como os estados de ânimo. / There are few studies analyzing the time course of mood during a competitive sports season. Although moods seem stable over the time course, different stimuli and present contexts change their intensity and valence. Furthermore, there are psychological phenomena like the decay process, in which information traces lose activation with the passage of time and expectancy, which is a waiting for an occurrence of an event in a given time. Therefore, the aim of this study was to exam mood changes in youth soccer players, grouped by position and role, which occurred during a competitive season, in function of time course. Processes like mood decay and the influence of expectation for the game were analyzed, as well as the influence of context in the athletes mood variations. Eighteen young players (15.4 ± 0,266 year-old) from a soccer club, which was playing for a state championship, participated in this study. For the assessment of mood, a short form of Lista de Estados de Ânimo Presentes (LEAP Present Mood List) was used, along with instructions to fill the form, applied few moments before some training sessions and matches. Presence values of each LEAPs Factor were calculated for each participant in each event. The data was collected in three types of events: prior to the last trainning session before the match (Treino-Pré), at a few moments before the match (Pré-jogo) and prior to the first training session after the match. The eighteen players were divided in two groups: Defensive Actions (AD) and Offensive Actions (AO). Results have shown patterns of mood changes, represented by LEAPs Factors II (Fatigue), VII (Interest) and XII (Serenity), in function of time course, allowing the analysis of mood decay process and the influence of the expectation in these changes. Also, some moods showed different patterns in function of a given time interval (Factors IV Limerence/Empathy and VII Interest), as well as different presence values in these time intervals comparison. Moreover, Factors III (Hope), V (Physiologic) and XI (Receptivity) have shown patterns of mood changes in function of time course in different intervals of time. Contextual variables, like the outcome of the matches and the sport competition itself, were influential in these changes. Fatigue, hope, empathy, states related to proprioception, interest, receptivity and serenity were the present moods all along the study. The importance of including temporality as an influential variable in neurobiological models is noteworthy, especially in the investigations about subjective aspects like mood.

Psychological Skills of Canadian Military Pilots

Hohmann, Maya Danielle 15 June 2011 (has links)
For decades, elite athletes have used mental skills training to enhance their performance. The effectiveness of these skills and strategies have been measured, documented and supported in research (e.g., Feltz & Landers, 1983; Vealey, 1994). As the remarkable benefits of mental skills continue to reach an ever-growing community of performers, it is surprising that many military organizations, known for their high standards for performance and little tolerance for error, have yet to take full advantage of this type of training. Canada’s Air Force (CAF), home to a world-renowned pilot training program, now finds itself seeking additional tools to empower pilots to achieve consistent, high quality performance under demanding, high stress conditions. The purpose of this research was to explore the psychological skills used by elite Canadian military pilots to perform successfully in this highly demanding occupation. Sixteen in-depth interviews were conducted with elite Canadian pilots at a CAF base in Saskatchewan. Results indicated that pilots utilized all seven elements of Orlick’s (2008) Wheel of Excellence over three phases of flight: pre-flight preparation, mission execution, and post-flight debriefs. Pilots also drew on elements of the Wheel of Excellence during deployments to combat zones. Effective stress management played an especially important role in this context. Recommendations for future research include mental skills usage and preparation specific to deployment contexts as well as the implementation of a specific, relevant mental skills training program within the existing CAF pilot training program

Does Writing Down Positive Self Talk – Self Reflection Affect Reaction Time? : A laboratory experiment with young Swedish athletes

Åkesdotter, Cecilia January 2012 (has links)
Syfte Syftet med studien är att undersöka om positivt Self-talk (ST) och självreflektion (SR) i form av att skriva i en träningsdagbok kan påverka reaktionstiden hos unga idrottare.   Sker det förändringar i reaktionstid mellan första och andra gången testet genomförs?   Är det en skillnad i hur stora förändringar som sker i reaktionstid när positivt self-talk gruppen och självreflektionsgruppen jämförs med en kontrollgrupp?   Hur upplevde idrottarna uppgiften att skriva träningsdagbok?   Metod Studien är ett randomiserat laboratorieexperiment och skillnader i reaktionstid kan enbart ses på gruppnivå. Deltagarna (n=29) bestod av både manliga och kvinnliga 16 åriga idrottare som randomiserades i två experimentgrupper och en kontrollgrupp. Kvinnor och män var jämt fördelade mellan grupperna. Först genomfördes två olika reaktionstest (Simple RT och 4choice RT) med hjälp av ett datorprogram för alla deltagare.  Experimentgrupp 1 (EG 1) genomförde en intervention där de under en vecka fick skriva ned sitt eget positiva ST i samband med träning. Experimentgrupp 2 (EG2) två skrev under en vecka ner vad de kunde förbättra med sin träning och vilka konsekvenser dessa förändringar kunde leda till. Kontrollgruppen (CG) fick utöver sin träning skriva ner sitt TV-tittande som en placebo. Efter interventionen genomfördes ett eftertest av reaktionstid och en enkät delades ut där deltagarna fick svara på hur de upplevde dagboken och om de trodde den kunde ha effekt på deras prestation.   Resultat Inom grupperna var det enbart EG 2 (de som tillämpade självreflektion) som hade en statistiskt signifikant förbättring av reaktionstid mellan det första och det andra testtillfället. Detta gällde både för Simple RT (p=0.028) och Choice RT (p=0.018). CG och EG 1 hade små förbättringar i RT mellan det första och andra testtillfället men inga som var statistiskt signifikanta. Gällande jämförelser mellan grupper fanns inga statistiskt säkerställda skillnader i förbättring mellan CG och EG 1. I EG 2 fanns ingen skillnad i förbättrad RT jämfört med CG i simple RT dock återfanns en statistiskt säkerställd skillnad i Choice RT där EG 2 hade en större förbättring jämfört med CG (p=0,003). Gällande hur grupperna upplevde interventionen med träningsdagböcker var resultaten relativt lika i de olika grupperna. Generellt upplevde grupperna att dagboken kunde ha en liten effekt på prestation samt att dagboksskrivandet i sig inte var så givande. Intressant var att de som skrev ner vad de såg på TV upplevde att detta kunde påverka deras prestation lika mycket som de som skrev ner positivt ST eller SR.   Slutsats I självreflektionsgruppen hade en statistiskt signifikant förbättring skett både inom gruppen och jämfört med en kontrollgrupp. Inga signifikanta skillnader återfanns i positivt ST gruppen. Resultaten tolkas utifrån teorier som Self-determination, information processning och förmågan att fokusera uppmärksamheten. Styrkor och svagheter behandlas och slutsatsen är att fler upprepade studier behövs för att stärka och förstå sambandet mellan positivt ST och SR kopplat till reaktionstid. Ska denna typ av dagbok föras in i en klubb eller ett lag bör designen göras om så att den blir mer omtyckt av idrottarna. / Aim The aim of this study is to evaluate if positive Self-talk (ST) or Self-Reflection (SR) by writing in a training diary can affect Reaction Time (RT) in young Swedish Athletes.   Does reaction time change between the pre-test and the post-tests?   Is there a difference in reaction time changes between groups when the positive ST group and the SR group are compared to the control group?   How did the athletes experience the intervention?   Experiment design This study is a randomized laboratory experiment. It is a between subjects design and therefore differences will only be seen on a group level. The participants N=29 were male and female 16 year old athletes. They were randomized in to two experiment groups (EG 1, EG 2) and a control group (CG), males and females were evenly distributed between groups. First two different (RT) tests were conducted with a computer program for all participants (Simple RT and 4Choice RT). After this an intervention of positive ST (EG1) or SR (EG2) was conducted with the use of training diaries for one week. The CG wrote down their habits of watching TV and this was used as a placebo. A re-test of RT was conducted after the completion of the intervention. After this an inquiry was handed to the participants to address their thoughts about using the diary and if they believed it could affect their performance.   Results EG2 was the only group that provided a statistically significant decrease in RT time compared to the pre-test in both simple RT (p=0.028) and choice (p=0.018). No statistical significant differences in RT were found in EG1 or in the CG when comparing pre-and post tests of both simple and choice RT. Comparing between groups showed no statistical significant difference in improved RT between the CG and EG 1 in simple RT or in 4choice RT. A statistical significant difference in improved RT was found between CG and EG2 in choice RT (p=0.003) where the EG 2 had a statistical significant improvement in RT compared to the CG. Comparing simple RT no statistical significant differences was found between EG2 and CG. The three groups experienced using the diary in a similar way. In general they found the diary intervention somewhat giving and believed that the diary could have a little affect on performance. Interesting to notice is that the participators that wrote down their TV habits believed this could have the same impact on performance as the participators writing down positive ST or SR.   Conclusions A connection was found between strategies of SR an RT. These results are analyzed regarding the theoretical framework provided by Self-determination theory, information processing and focus of attention. Strength and weakness is discussed and the conclusion is that more and reproduced studies are needed to determine the connection between interventions positive ST, SR and RT. If a training diary would be used in a team or a club some modifications should be done to make them more meaningful for the athletes.

PERSEVERANCE THROUGH MENTAL BLOCKING: EXPLORING COACH-ATHLETE DYADIC RELATIONSHIPS

2015 May 1900 (has links)
Collective case study (Creswell, 2014; Stake, 1995) was used to explore the journey of coach-athlete dyads who were able to successfully maintain their training and interpersonal relationships throughout the course of the athlete enduring a mental block. Three coach-athlete dyads, plus one additional athlete, completed in-depth one-on-one interviews, discussing their coach-athlete relationship before, during, and after the mental block. All dyads were same sex, nationally ranked coach-athlete pairs, from sports involving mandatory elements that include both twisting and flipping components. Categorical aggregation of participant statements lead to the formation of five main themes associated with dyads successfully overcoming a mental block (where success was defined as the athlete regaining the ability to perform the skill that they had previously been unable to do on account of the mental block and the dyad maintaining their training and interpersonal relationship): 1) Get to Know Your Athlete: The Need for High Quality Communication; 2) Be a United Front; 3) Mistakes and Miscommunications Happen: Recovery is Key; 4) Seek Outside Resources; 5) Be Patient. Results suggest that an environment for success can flourish when each party is open, honest, and self-aware of their own limitations. It is suggested that future research utilize the 3 + 1Cs Model of the coach-athlete relationship in exploring how dyads can successfully overcome a mental block.

Exposure to, perceptions and levels of mental skills among tertiary institution field hockey players / Maryke Eloff

Eloff, Maryke January 2010 (has links)
The importance of mental skills training (MST) is emphasized by previous/available research findings which show that by combining MST with physical training it enhances players’ ability to cope with the demands of the sport and subsequently results in better sport performance. The main aims of the present study (presented in two articles which can be read independently) were twofold. The first was to determine field hockey players’ perceived need for MST, and their perception regarding their ability to prepare psychologically for matches, as well as compile a general profile of their psychological skill for the total group and by gender. The second aim of the study was to determine the possible positional differences in mental skill levels among 91 South African tertiary institutions’ male field hockey. A total of one hundred and ninety seven (91 males and 106 females) South African field hockey players who competed in the 2008 University Sport of South Africa tournament participated in the study. The participants completed the Psychological Skills Inventory (PSI) and the Ottawa Mental Skills Assessment Tool–3 (OMSAT–3) questionnaires. The results from Article 1 showed significant gender differences from the Psychological Skills Inventory (PSI) according to which the males outperformed the females in the skills of concentration, activation and activation control. In addition, significant gender differences were observed for mental skills training (MST) measures for goal–setting and commitment in which the females outperformed the males, whilst the males fared better than the females in stress reaction. The hockey players perceived MST as important to enhance performance in field hockey. The players furthermore perceived their ability to prepare psychologically for matches as good, which contradicts the results from the questionnaires as the players showed poor mean scores for five of the six subscales of the PSI questionnaire. The results from article 2 showed that the goalkeepers had the lowest scores for seven of the 12 tested skills, whereas midfielders outperformed the other positions in six of the 12 subscales. It is clear from these results that MST is important for field hockey and therefore warrants the attention of all role players in field hockey. / Thesis (M.Sc.
