- Perceived Effort in Football Athletes: The Role of Achievement Goal Theory and Self-Determination TheoryPublication . Monteiro, Diogo; Teixeira, Diogo S.; Travassos, Bruno; Duarte-Mendes, Pedro; Moutão, João; Machado, Sérgio; Luís, CidThis study examined the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving climate, basic psychological needs, self-determined motivation (SDM), and perceived effort. Additionally, SEM multi-group analysis across different age-groups (U15, U17, U19, and U21 years) and serial mediation of basic psychological needs (BPNs) and SDM on the task-involving motivational climate and the perceived effort were also analyzed. Two independent samples of male football athletes (N = 403, N = 403), aged 13–20 years were enrolled in this study. The results support the adequacy of the structural model in explaining the perceived effort of football atheltes in all samples under analysis, and was invariant across U17, U19, and U21. However, it was not invariant across U15 and U17, U19 and U21. Furthermore, results from the serial mediation showed significant indirect effects in all samples, supporting self-determination theoretical assumptions, reinforcing the importance of BPNs satisfaction and behavioral regulation in the relation in analysis. The results show that when coaches promote a task-involving climate, the BPNs satisfaction of athletes improves. This climate will facilitate the regulation of their behaviors toward more autonomous forms of motivation, with positive outcomes in the athletes perceived effort.
- Effects of an imagery programme on the performance of federated and non-federated Boccia athletesPublication . Amorim, André; Travassos, Bruno; Monteiro, Diogo; Baptista, Liliana; Duarte-Mendes, PedroThe aim of this study was to analyse the effects and the relations through the implementation of an imagery (IM) training programme for federated and non-federated Boccia participants. Twenty-one Boccia athletes participated in this study. At the beginning of the study, and after a period of an 8-week IM training, the athletes’ IM ability (MIQ – 3) and their performance in Boccia tasks (distance to target and distance to coloured ball) were assessed. Data analysis was carried out using non-clinical magnitude-based inferences. The results suggests that, from pre to post test, federated and non federated athletes had a higher IM score and exhibited an improved performance. The performance levels seem to have been influenced by the participants’ level of expertise, with the non-federated athletes revealing higher magnitude of improvement than federated athlete’s. A non-significant correlation was observed between IM and performance. Although the inconsistency of the relationship between IM and performance, the results suggests that IM training enhances the development of IM ability and also motor actions in Boccia athletes.
- Evaluation of the psychometric properties of the portuguese peabody developmental motor scales - 2 edition: a study with children aged 12 to 48 monthsPublication . Rebelo, Miguel; Serrano, João; Duarte-Mendes, Pedro; Monteiro, Diogo; Paulo, Rui; Marinho, DanielThe purpose of this study was to examine the psychometric properties of Peabody Developmental Motor Scales II (PDMS-2-Folio and Fewell, 2000) using a Portuguese sample. The validation of the Portuguese version of the PDMS-2 was applied according to the manual, for 392 children, from two institutions, from 12 to 48 months, with an analysis of the internal consistency (α Cronbach), of test–retest reliability (ICC) and construct validity (confirmatory factor analysis). The results of the confirmatory factorial analysis (χ2 = 55.614; df = 4; p = 0.06; χ2/df =13.904; SRMR (Standardized Root Mean Square Residual) = 0.065; CFI (Comparative Fit Index) = 0.99, TLI = 0.99, RMSEA (Root Mean Square Error of Approximation) = 0.068) of two factors (Gross Motor and Fine Motor) as the original version but correlated. Most of the subtests had good internal consistency (α = 0.85) and good test–retest stability (ICC = 0.98 to 0.99). The results indicated that the Portuguese version of the PDMS-2 is adequate and valid for assessing global and fine motor skills in children aged 12 to 48 months, and can be used as a reference tool by health and education professionals to assess motor skills and, thus, allowing to detect maladjustments, deficiencies or precocity, so that children can later receive appropriate intervention.
- The comparison of Imagery ability in elite, sub-elite and non-elite swimmersPublication . Duarte-Mendes, Pedro; Marinho, Daniel; Monteiro, Diogo; Cid, Luís; Paulo, Rui; Serrano, João; Petrica, JoãoThe ability to generate and control mental images is present in all of us, but it differs from person to person. Therefore, it is important to understand that imagery ability can be changed through training and experimentation, it is not a fixed ability. The aim of this study is to compare imagery ability in elite, sub-elite and non-elite athletes in a sport which involves closed and continuous motor skills, such as swimming. 79 swimmers (male N = 37; female N = 42) at an average age of 17 took part in this study. In order to assess imagery ability, the Movement Imagery Questionnaire 3 was used, Portuguese version (Mendes et al., 2016). After analysis of the results, these show that in each and every imagery modality, the scores in the three groups differ significantly. In kinesthetic and external visual imagery the elite and sub-elite groups’ scores, although not statistically different from each other, are significantly higher than those of the non-elite group. In internal visual imagery, the differences between all the compared pairs of groups are statistically significant. The elite group got the highest scores, followed by the sub-elite group average scores and finally the non-elite group average scores. According to these results, the conclusion is that athletes with better performance show greater imagery ability and that apparently the external visual imagery proved to be the best intervention method among swimming athletes.
- Assessing Need Satisfaction and Frustration in Portuguese Exercise Instructors: scale validity, reliabity and invariance between genderPublication . Rodrigues, Celia F.; Neiva, Henrique; Marinho, Daniel; Duarte-Mendes, Pedro; Teixeira, Diogo S.; Cid, Luís; Monteiro, DiogoObjective: The aim of the present study was to validate the Basic Psychological Need Satisfaction and Frustration Scale in Exercise for fitness instructors. Methods: Data from 477 exercise professionals (319 males, 158 females) was collected. Results: CFA supported the adapted and validated six-factor model: [χ2(237) = 1096.796, χ2/df= 4.63; B-S p < .001, CFI = .930, TLI = .918, SRMR= .0366, RMSEA = .079 (CI90% = .069, .089)], assessing satisfaction and frustration of basic psychological needs in Portuguese exercise professionals. Moreover, the analysis revealed acceptable composite reliability, and construct validity of the adapted version. Results revealed nomological validity, as well as invariance between male and female. No differences were found across latent means, and magnitude effects were trivial between gender. Conclusion: These results support the use of the adapted scale in exercise professionals, showing measurement invariance between gender. This scale is able to measure how exercise professionals experience satisfaction and frustration of basic needs when prescribing exercise to individuals in fitness context.
- Changes in metabolic and inflammatory markers after a combined exercise program in workers : a randomized controlled trialPublication . Silva, Fernanda; Duarte-Mendes, Pedro; Ferreira, José P.; Carvalho, Eugénia; Monteiro, Diogo; Massart, Alain; Farinha, Carlos; Soares, Carlos M.; Teixeira, AnaPurpose: We investigated the effects of a 16-week combined exercise training on body composition, metabolic and inflammatory markers in sedentary middle-aged workers. We also assessed whether significant alterations in metabolic markers were associated with changes in health-related outcomes. Methods: This randomized controlled trial involved 46 participants randomly allocated into control and exercise groups. The exercise group performed 16-week combined aerobic and resistance training for 75 min/session, 3 times/week. Fasting blood samples were collected at baseline and after 16-week intervention to determine lipid profile, metabolic and inflammatory markers as primary outcomes. Results: A total of 36 participants completed the intervention (53.70 ± 6.92 years old) (n = 18 in each group). Waist circumference (interaction effect: F = 7.423, p = 0.002), fat mass (interaction effect: F = 5.070, p = 0.011), and muscle mass (interaction effect: F = 5.420, p = 0.007) were improved in the exercise group compared to the control group. Fasting glucose increased after the 16-week follow-up (time effect: F = 73.253, p < 0.001), without an intergroup difference. Insulin levels were greater in the control compared to exercise group (group effect: F = 6.509, p = 0.015). The control group tended to increase the HOMA-IR index (interaction effect: F = 3.493, p = 0.070) and to decrease the QUICKI index (interaction effect: F = 3.364, p = 0.075) to a greater extent compared to the exercise group. Exercise group reduced leptin (interaction effect: F = 11.175, p = 0.002) and adiponectin (interaction effect: F = 4.437, p = 0.043) concentrations in a greater magnitude than control group. IL-6 (time effect: F = 17.767, p < 0.001) and TNF-α (time effect: F = 9.781, p = 0.004) concentrations decreased after the intervention, without an intergroup difference. IL-17A levels increased in the control compared to exercise group (interaction effect: F = 5.010, p = 0.033). Effects on adiponectin, IL-6 and IL-17A levels seem to depend on baseline BMI, age, and sex. Percentage changes in leptin correlated positively with changes in HOMA-IR index in the exercise (r = 0.565, p = 0.015) and control (r = 0.670, p = 0.002) groups. Conclusions: A combined training program can be an effective strategy to improve body composition and inflammatory markers and prevent marked reductions in insulin sensitivity among middle-aged workers.
- Heart rate variability behavior in athletes after a sports concussion : a systematic reviewPublication . Flores, Gonçalo; Monteiro, Diogo; Silva, Fernanda; Duarte-Mendes, PedroObjective: This systematic review aims to investigate the adaptations of the autonomic nervous system (ANS) after a concussion by measuring HRV in athletes over the age of 16 after injury. Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Web of Science, Pubmed, SCOPUS, and Sport Discus were searched using predefined search terms to identify relevant original cross-sectional, longitudinal, and cohort epidemiological studies published before December 2021. Results: After screening 1737 potential articles, four studies met the inclusion criteria. Studies included participants with concussion (n = 63) and healthy control athletes (n = 140) who practised different sports. Two studies describe a decrease in HRV following a sports concussion, and one proposed that the resolution of symptoms does not necessarily reflect ANS recovery. Lastly, one study concluded that submaximal exercise induces alteration in ANS, not seen in rest after an injury. Conclusions: In the frequency domain, a decrease in high frequency power and an increase of low frequency/high frequency ratio is expected, as the activity of the sympathetic nervous system increases, and the parasympathetic nervous system decreases after injury. In the frequency domain, heart rate variability (HRV) may help monitor the activity of ANS evaluating signals of somatic tissue distress and early identification of other types of musculoskeletal injuries. Further research should investigate the relationship between HRV and other musculoskeletal injuries.
- Motivational determinants of physical education grades and the intention to practice sport in the futurePublication . Rodrigues, Luísa; Pires, Ana; Borrego, C.; Duarte-Mendes, Pedro; Teixeira, Diogo S.; Moutão, João; Monteiro, DiogoSelf-Determination Theory (SDT) is amongst motivational frameworks the most popular and contemporary approach to human motivation, being applied in the last decades in several domains, including sport, exercise and physical education (PE). Additionally, Achievement Goal Theory (AGT) has presented evidence of how contextual factors may influence student’s behavior in this particular context. The main purpose of this study was to analyze the motivational climate created by the teacher in the classroom, students’ satisfaction of Basic Psychological Needs (BPN), and how their behavioral regulation could explain PE grades and intention to practice sports in the future. Method: A total of 618 students (290 female; 328 male) from the 6th to the 9th school level, aged between 10 and 18 years (M = 13.3; SD = 1.7) participated in this study. The following surveys were used for the proposed variables: Learning and Performance Orientations in Physical Education Classes Questionnaire (LAPOPECQ); the Basic Psychological Needs in Exercise Scale (BPNESp); and the Perceived Locus of Causality (PLOCp). Intentions to practice sport/physical activity in the future were assessed through a single item. Students’ PE grade was obtained through his/her teacher final assessment. Structural Equation Analysis was performed via AMOS 23.0. Results: After analyzing modification indices and model adjustment, the final model emerged: learning climate > BPN > autonomous motivation > intentions/PE grade. Results interpretation seems to indicate that i) the satisfaction of BPN are influenced by motivational climate (i.e., learning climate), ii) the individuals’ motivation is influenced by the satisfaction of three basic psychological needs (i.e., particularly competence), and iii) the motivational regulations have direct and significant effects with intention to practice sports outside school in the future and PE grades. Discussion & Conclusion: The main results showed that a climate oriented for learning has a positive impact on basic psychological needs satisfaction of students. However, only competence satisfaction had a significant positive relationship with students’ autonomous motivation, which in turn had a significant positive relation with PE grade, as well as for intentions for leisure-time sport/physical activity practice.
- Objectively Measured Physical Activity and Sedentary Behaviour on Cardiovascular Risk and Health-Related Quality of Life in Adults: A Systematic ReviewPublication . Santos, Beatriz; Monteiro, Diogo; Silva, Fernanda; Flores, Gonçalo; Bento, T.; Duarte-Mendes, PedroBackground: This systematic review analysed the association between objectively measured physical activity and sedentary behaviour with cardiovascular risk and HRQoL in adults without previous CVD. Additionally, we analysed the impact of the intensity of the physical activity in this association. Methods: The search was carried out in three electronic databases with access until February 2023 to find studies with an observational design. For quality assessment, we used The National Institute of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: We identified 5819 references, but only five studies were included. One study shows a positive association between physical activity and HRQoL, while sedentary behaviour was negatively related to HRQoL. Another study showed an association between high-intensity physical activity with a better physical component of HRQoL and low-intensity physical activity with a better mental component of HRQoL. Three studies concluded that higher levels of physical activity are associated with lower levels of cardiovascular risk and higher levels of sedentary behaviour are associated with higher levels of cardiovascular risk. Conclusion: Our findings suggested that people who spend more time being active and spend less time being sedentary appear to have lower cardiovascular risk and higher HRQoL.
- Tradução e validação do Movement Imagery Questionnaire – 3 (MIQ-3) com atletas portuguesesPublication . Duarte-Mendes, Pedro; Marinho, Daniel; Petrica, João; Silveira, Paulo; Monteiro, Diogo; Cid, LuisImagery é um processo cognitivo que pode desempenhar um papel importante no planeamento e execução de movimentos ou ações. Vários instrumentos têm sido desenvolvidos com o intuito de avaliar a habilidade de Imagery no desporto. No entanto, nenhum se focou na modalidade cinestésica, visual interna e visual externa. O objetivo deste estudo foi traduzir e validar preliminarmente para a população desportiva portuguesa o Movement Imagery Questionnaire-3, determinando as suas qualidades psicométricas iniciais através de uma análise fatorial exploratória do modelo que a suporta. A amostra foi constituída por 176 sujeitos (N = 176) (sexo masculino N = 134; sexo feminino N = 42) com uma média de idades de 20.08 anos (SD = 5.94), composta por atletas de futebol (N = 113), basquetebol (N = 43) e ténis (N = 20). Numa primeira fase verificou-se que os procedimentos de tradução e adaptação originaram uma versão Portuguesa do MIQ - 3 semelhante à versão original. Numa segunda fase verificamos que as qualidades psicométricas comprovam a adequação da adaptação efetuada, demonstrando que a sua estrutura fatorial é igual à versão original (12 itens agrupados em 3 fatores, com 4 itens cada fator), apresentando índices bastante aceitáveis de validade e fiabilidade (alfa de Cronbach: 0.88 para MIQ - 3, 0.79 para as três modalidades), concluindo que este questionário poderá ser utilizado para avaliar a capacidade de Imagery em atletas Portugueses.
