- Accelerometer-Measured Daily Step Counts and Adiposity Indicators among Latin American Adults: A Multi-Country StudyPublication . Ferrari, Gerson; Marques, Adilson; Barreira, Tiago V.; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Yépez García, Martha Cecilia; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Guajardo, Viviana; Leme, Ana Carolina B.; Guzman-Habinger, Juan; Valdivia-Moral, Pedro; Suárez-Reyes, Mónica; Ihle, Andreas; Gouveia, Élvio R.; Fisberg, MauroThe aim of the present study was to examine the sex-related associations between accelerometer measured daily step counts and adiposity indicators in adults from eight Latin American countries. We analyzed data from 2524 adults (aged 18–65 years) from the Latin American Study of Nutrition and Health. Device-measured daily step counts were measured by accelerometers (ActiGraph GT3X). The outcomes were body mass index (BMI; (kg/m2), waist and neck circumference (in cm). Overall, the mean of daily steps counts, BMI, waist and neck circumference were 10699.8, 27.3, 89.6, and 35.8. Weak and negative associations were observed between daily steps counts and BMI (r = −0.17; p < 0.05) and waist circumference (r = −0.16; p < 0.05); however, step counts was not associated with neck circumference. Daily steps counts were negatively associated with BMI (β: −0.054; 95%CI: −0.077; −0.012) and waist circumference (−0.098; −0.165; −0.030) independently of age and socioeconomic level. In men, there were significant negative associations between daily steps counts with BMI (−0.075; −0.119; −0.031) and waist circumference (−0.140; −0.233; −0.048), and in women, there was no significant association with either of the body composition indicators. The findings from this study need to be examined in prospective settings that use device-measured from Latin America.
- Analyzing parental involvement in youth basketballPublication . Lopes, Maria V.; Ihle, Andreas; Gouveia, Élvio Rúbio; Marques, Adilson; França, Cíntia; Ihle, Andreas; Gouveia, Élvio Rúbio; Marques, Adilson; França, CíntiaParental involvement in youth sports is increasingly relevant in scientific research since parents have gradually developed awareness regarding youngsters’ sports experiences. This study aimed to (1) examine potential differences in athletes’ and parents’ perceptions of parental involvement practices in youth basketball, (2) verify whether these perceptions differ by sex, and (3) analyze the relationship between the different perceptions dimensions recorded. The analysis included a large sample of 423 Portuguese participants (151 youth basketball athletes and 272 parents) who completed the Parental Behaviors in Sports (PBSP) questionnaire. The PBSP comprises a version for parents and a version for athletes, composed of five dimensions: (1) sports support, (2) competition attendance, (3) technical influence, (4) performance pressure, and (5) sports expectations. No significant statistical differences regarding PBSP dimensions were observed between boys and girls in the athletes’ group. However, in the parents’ group, fathers scored significantly lower than mothers in sports expectations (p = 0.001). Differences between athletes’ and parents’ perceptions were evident in competition attendance (p = 0.023), technical influence (p ≤ 0.001), and sports expectations (p = 0.023). When analyzing the dyads of boys–fathers and girls–mothers, significant differences were found for technical influence (p = 0.035), performance pressure (p = 0.020), and sports expectations (p < 0.001) between boys and fathers. Among girls and mothers, differences were perceived exclusively for technical influence (p = 0.005). Finally, technical influence correlated significantly with performance pressure (r = 0.351, p < 0.001) and sports expectations (r = 0.367, p < 0.001). These findings demonstrate the crucial importance for sports researchers and practitioners to consider differences in perceptions based on sex and role (athlete or parent) when designing and implementing parental educational programs.
- A associação entre o estilo de vida e a atitude de alunos do ensino básico e secundário em relação à disciplina de educação físicaPublication . Gouveia, Élvio Rúbio; Ihle, Andreas; Rodrigues, Ana; Correia, Ana Luisa; Alves, Ricardo; Simões, Joana; Gouveia, Bruna; Kliegel, Matthias; Freitas, Duarte; Lopes, HelderEste estudo teve por objetivo o seguinte: investigar a associação entre o estilo de vida e a atitude positiva (EñgEFD) ou negativa (EgEFD) dos alunos sobre a Educação Física (EF). Um estudo de natureza transversal foi conduzido em 243 estudantes (15.6 ±2.5 anos). A informação demográfica, a opinião sobre a EF, e a auto perceção foram avaliados através de questionários. A aptidão física foi determinada a partir da FITNESSGRAM e da EUROFIT. A percentagem de gordura foi estimada a partir das equações de Slaughter et al., (1988). Análises descritivas e o t-test de medidas independentes foram conduzidas nas análises. Nesta amostra, 74.5% dos estudantes afirmam gostar de EDF. Os EgEFD apresentam scores significativamente mais elevados comparativamente aos EñgEFD na força, velocidade/agilidade, força resistência do tronco e resistência aeróbia (p<.007). Os EgEFD têm uma melhor percepção das suas capacidades físicas, assim como referem ter uma boa saúde e adotarem estilos de vida mais saudáveis (p<.001). Os EgEFD apresentam um perfil funcional e psicológico mais saudável, auto percecionam um melhor estado de saúde e preferem envolver-se em atividades físicas em detrimento das atividades sedentárias no seu dia-a-dia.
- Association between the Duration of the Active Commuting to and from School, and Cognitive Performance in Urban Portuguese AdolescentsPublication . Rodrigues, Ana José Aguiar; Antunes, Hélio; Alves, Ricardo; Correia, Ana Luisa; Lopes, Helder; Sabino, Bebiana; Marques, Adilson; Ihle, Andreas; Gouveia, Élvio Rúbiohis study aimed to analyze the differences between active commuting to school (ACS) and non-ACS in cognitive performance (CP), and the association of ACS duration with CP. This cross-sectional study included 370 adolescents (males n = 170), with a mean age of 15.28 ± 2.25 years. CP was assessed through an interview, and ACS, extracurricular physical activity, and socioeconomic status was assessed by self-report. Body composition was assessed using the FitnessGram test battery. One in two adolescents did ACS (51.6%). ACS was associated with boys (53.9%), younger adolescents (14.91 ± 2.15 vs. 15.69 ± 2.29), those having school social support (55.0%), and those doing one or more extracurricular physical activities (53.6%), compared to non-ACS participants (p < 0.05). The analysis of covariance, after controlling for age, sex, school social support, and participation in extracurricular physical activity, showed an effect of ACS on the total cognitive score (F(2,362) = 3.304, p < 0.05). The CP was higher in adolescents with more than 30 min of ACS than non-ACS (p < 0.05). The influence of ACS duration can be seen in the dimensions of inductive reasoning (ß = 0.134, t = 2.587, p < 0.05) and working memory (ß = 0.130, t = 2.525, p < 0.05). The role of ACS for CP, as well as guidelines for future research, are discussed.
- Associations between Age, Body Composition, Balance, and Other Physical Fitness Parameters in Youth SoccerPublication . França, Cíntia; Martins, Francisco; Marques, Adilson; Nascimento, Marcelo de Maio; Ihle, Andreas; Przednowek, Krzysztof; Gouveia, Élvio RúbioIn sports, balance ability has been related to game performance and injury prevention. This study’s aims were twofold: (1) to analyze the balance performance of adolescent soccer players from different age groups; and (2) to examine the relationship between players’ age, body composi tion, balance, and other physical fitness parameters, such as strength and flexibility. In this study, 112 players from the under 15 (U15), under 16 (U16), and under 17 (U17) age groups participated. A one-way analysis of the variance was conducted to investigate differences between groups. Pearson correlations and hierarchical multiple regression were used to explore the relationship between variables. Regarding balance, the older group performed significantly worse in the stability indexes for both legs but significantly better in dynamic balance tests. Height correlated significantly and negatively with balance indicators. Both jumping tasks showed medium to large correlations with the sway indexes (−0.23 > r < −0.51). Although not significantly, body fat negatively affected balance, underlining the importance of monitoring body composition for players’ development. Overall, no substantial relationship was found between static and dynamic balance variables, and therefore, it is crucial to include both as complementary measures while evaluating youngsters’ postural balance.
- Associations between muscular strength and vertical jumping performance in adolescent male football playersPublication . França, Cíntia; Marques, Adilson; Ihle, Andreas; Nuno, João; Campos, Pedro; Gonçalves, Frederica; Martins, João; Gouveia, ÉlvioThis study aimed to investigate the associations between muscular strength tests and vertical jumping performance (countermovement jump [CMJ] and squat jump [SJ]) in adolescent male football players, while controlling for important predictors such as chronological age and body composition. Methods. The sample involved 161 male footballers (mean age: 15.8 ± 1.7 years) from the under-19, under-17, and under-15 age groups. Body fat percentage (BF%) was calculated with Slaughter equations. Muscular strength assessment included handgrip strength and push-up and sit-up tests. Vertical jumping was examined through CMJ and SJ. Pearson correlations and hierarchical regression analyses were run to analyse the data. Results. All muscular strength tests showed significant correlations with CMJ and SJ. Handgrip strength was the most substantial predictor for CMJ (r = 0.43, p < 0.01) and SJ (r = 0.44, p < 0.01). However, regression models identified sit-ups (CMJ: = 0.15, p < 0.01, R2 = 0.23; SJ: = 0.16, p < 0.01, R2 = 0.27) and push-ups (CMJ: = 0.13, p < 0.01; SJ: = 0.15, p < 0.01) as significant predictors after controlling for chronological age, body mass, and BF%. In contrast, BF% remained a significant predictor of jumping performance (CMJ: = –0.43, p < 0.01, R2 = –0.39; SJ: = –0.52, p < 0.01, R2 = –0.52) in the whole hierarchical regression model. Conclusions. This study reinforces the importance of players’ overall physical development, including healthy diet habits, to enhance jumping performance.
- Associations of Gait Speed, Cadence, Gait Stability Ratio, and Body Balance with Falls in Older AdultsPublication . Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; Gouveia, Bruna R.; Marques, Adilson; Martins, Francisco; Przednowek, Krzysztof; França, Cíntia; Peralta, Miguel; Ihle, AndreasTo investigate the association between gait speed (GS), cadence (CAD), gait stability ratio (GSR), and body balance (BB) with falls in a large sample of older adults. The analysis included 619 individuals—305 men and 314 women (69.50 ± 5.62 years)—residing in the Autonomous Region of Madeira, Portugal. Mobility in GS, CAD, and GSR was assessed using the 50-foot walk test and BB by the Fullerton Advanced Balance scale. The frequency of falls was obtained by self-report. Linear regression analysis showed that higher performance in GS and BB was able to reduce the risk of falling by up to 0.34 and 0.44 times, respectively. An increase in the GSR value enhanced the risk of falling by up to 0.10 times. Multinomial analysis indicated that, in relation to the highest tertile (reference), older adults classified with GS and BB performance in the lowest tertile (lowest) had an increased chance (OR) of falling by up to 149.3% and 48.8%, respectively. Moreover, in relation to the highest tertile, the performance of the GSR classified in the lowest and medium tercile showed an increase in the chance of falling by up to 57.4% and 56.4%, respectively

França, Cíntia; França, Cíntia; Martins, Francisco; Pestana Martins, João Francisco; Przednowek, Krzysztof; Marques, Adilson; Marques, Adilson; Ihle, Andreas; Ihle, Andreas; Sarmento, Hugo; Borges Sarmento, Hugo Miguel; Sarmento, Hugo; Gouveia, Élvio Rúbio; Gouveia, Élvio Rúbio; Gouveia, Elvio Rúbio; Gouveia, Elvio RúbioNo futebol, a avaliação e monitorização da força ao nível das articulações do joelho e da anca tem sido recomendada no âmbito da prevenção de lesões. Este estudo emerge com os seguintes objetivos: (1) comparar o desempenho da produção de força ao nível das articulações do joelho e da anca entre futebolistas enquadrados em diferentes níveis competitivos; (2) comparar o desempenho da produção de força de acordo com o membro inferior dominante (MD) e o membro inferior não-dominante (MND) em dois momentos da época (M1 e M2). Foram avaliados 33 futebolistas profissionais do sexo masculino: 13 enquadrados no grupo de elite (GE) e 20 enquadrados no grupo de sub-elite (GSE). As avaliações incluíram a composição corporal, o desempenho dos músculos flexores e extensores do joelho a 60º/s, e o desempenho dos músculos adutores da anca. Para a análise, o valor de pico de torque (PT) foi normalizado com base na massa corporal para os músculos flexores e extensores do joelho. No M1, os resultados indicam diferenças estatisticamente significativas entre grupos, favorecendo o GE, no desempenho dos flexores a adutores no MD e MND (p < 0.01). No M2, o GE apresentou um desempenho substancialmente superior nos músculos extensores e flexores (p < 0.01). Na comparação entre a produção de força entre MD e MND, ganhos estatisticamente significativos foram observados entre o M1 e M2 em ambos os grupos (p < 0.01). Na análise global, os futebolistas do GE demonstraram um desempenho superior nos indicadores de força muscular comparativamente ao GSE.
- Balance and mobility relationships in older adults: A representative population-based cross-sectional study in Madeira, PortugalPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Ihle, Andreas; Kliegel, Matthias; Marques, Adilson; Freitas, Duarte L.Background: Balance and mobility impairments are important modifiable risk factors associated with falls in older people. Purpose: To investigate how different functional fitness components relate to balance and mobility, after controlling for age, sex, body mass index (BMI), and different physical activity (PA) domains. Methods: This representative cross-sectional study included 802 individuals, 401 males and 401 females (69.8 ± 5.6 years) from Madeira, Portugal. The Fullerton Advance Balance (FAB) scale was used to assess balance. Mobility in terms of gait velocity, cadence, stride length, and gait stability ratio (GSR) were assessed using the 50-foot Walk test. PA was assessed through a face-to-face interview using the Baecke questionnaire, and functional fitness was assessed with Senior Fitness tests (strength, flexibility, and aerobic endurance). Results: Balance and mobility were negatively associated with age and BMI, and positively related to PA and functional fitness. Moreover, male presented better performance in balance and mobility. Hierarchical multiple regression analyses showed that functional fitness explained the highest amount of variance in balance and all mobility parameters(over andaboveage,sex,BMI,and PA).Specifically, entering functional fitnesscomponents significantly increased explained variance in FAB (+19%), gait velocity (+25%), cadence (+15%), stride length (+9%), and GSR (+ 31%). In these models, aerobic endurance consistently had the strongest contribution. Conclusion: Strength, flexibility, and especially aerobic endurance, over and above non-modifiable variables like age and sex, are crucial for maintaining or improving balance and mobility and, thereby, prevent falls in older people.
- Bidirectional Association between Physical Activity and Dopamine Across Adulthood—A Systematic ReviewPublication . Marques, Adilson; Marconcin, Priscila; Werneck, André O.; Ferrari, Gerson; Gouveia, Élvio R.; Kliegel, Matthias; Peralta, Miguel; Ihle, AndreasPhysical activity (PA) may influence the secretion of neurotransmitters and thereby have positive consequences for an individual’s vulnerability (i.e., reducing anxiety and depressive symp toms). This systematic review aims to analyse the potential bidirectional effects of exercise on dopamine from young adulthood to old age. The article search was conducted in PubMed, Scopus, and Web of Science in December 2020. The inclusion criteria were longitudinal and experimental study design; outcomes included dopamine and exercise; effect of exercise on dopamine and vice versa; adults; and articles published in English, Portuguese, or Spanish. Fifteen articles were included in the review. We observed robust findings concerning the potential effects of PA on dopamine, which notably seem to be observable across a wide range of participants characteristics (including age and sex), a variety of PA characteristics, and a broad set of methods to analyse dopamine. By contrast, regarding the potential effects of dopamine on PA, findings were mixed across studies. Thus, there are robust effects of physical exercise on dopamine. These findings further strengthen the idea that innovative approaches could include PA interventions for treating and preventing mental disorders. Therefore, it seems that PA is a potential alternative to deal with mental health issues.
