- A systematic review on dry-land strength and conditioning training on swimming performancePublication . Amaro, N.M.; Morouço, P.G.; Marques, M.C.; Batalha, N.; Neiva, Henrique P.; Marinho, D.A.Objectives. — The objective of this review was to examine the effects of dry-land strength and conditioning (S&C) training on swimming, and starts and turns performances. News. — S&C training is a common practice in swimming aiming to enhance performance or to prevent injuries. However, studies regarding the effects of S&C on swimming performance are scarce; the influence of age, gender or competitive level is even scarcer. Prospects and projects. — After a structured literature search, sixteen studies were included in the current review. Of those, seven did not report any positive or negative effects on swimming performance. Contrarily, most studies with positive effects were conducted with older swimmers whereas maximal strength was the most effective methodology for improving swimming performance. S&C plyometric training is suggested to be the most effective method to improve starts and turns. Future Randomized Controlled Trials should be conducted to explorethe effects of S&C induced by age and gender, on different swimming distances and techniques,and long-term training effects.Conclusion. — It is recommended that S&C training should be based on maximal strength, rangingfrom six to twelve weeks of 2 to 4 sessions per week (approximately 24 sessions altogether). Ineach session, coaches should vary from 2 to 3 sets and 3 to 5 repetitions, according to prescribedintensity. Rest intervals should range between 2 to 5 minutes and the intensity should be from 80to 90% of 1RM. Particularly regarding improving starts and turns, a S&C training regime rangingfrom 6 to 8 weeks and with 2 sessions per week is suggested. In each session, swimmers shouldperform between 1 and 6 sets and 1 and 10 repetitions, according to the established intensity.Rest between sets should range from 60 to 90 seconds. The swimmers in the included studiesare mostly men which do not allow to say if the recommendations made are gender-dependent.© 2018 Elsevier Masson SAS. All rights reserved.
- Assessing the impact of strength training in the functional fitness of the elderlyPublication . Salvador, Rogério; Frontini, RobertaBACKGROUND: The health benefits of resistance training have been vastly valued in opposition to strength training. Nonetheless, literature has consistently acknowledged the clinical and functional benefits of strength training. The main aim of this study was to better understand the impact of the inclusion of a strength training on the functional aptitude of elderly participants. METHODS: This observational research recruited the sample at a local wellness center. Participants were part of two different groups: a Control Group and a Strength Training Group. Both groups were assessed in the beginning and at the end of the school year. A validated adaptation of The Senior Fitness Test was used. Height, weight, Body Mass Index, and body fat mass were also calculated. RESULTS: Regarding the differences from Time 1 to Time 2, the Strength Training Group obtained a statistically significant result on the chair stand and the Body Mass Index, with a large and a moderate effect respectively. The Control Group had a statistically significant result on the chair sit-and-reach, the two-minute step test and the percentage of body fat mass. CONCLUSIONS: The results seem to suggest that the two training methodologies may be effective in improving the functionality of the elderly. Strength training revealed potential contributions in the improvement of some of the results, such as flexibility of the upper limbs or even strength of the lower limbs.
- Comparison of motivational factors for the practice of exercise at gyms and nature and adventure sportsPublication . Frontini, Roberta; Brandão, António; Monteiro, Maria; Salvador, Rogério; Lima, Ricardo Franco; Fernandes, Daniel; Clemente, Filipe ManuelPhysical inactivity continues rising making it necessary to understand what motives the practice of physical exercise and sports. 901 Portuguese practitioners of exercise at gyms and nature and adventure sports modalities were recruited. Participants answered to the Portuguese version of the Exercise Motivations Inventory-2 (EMI-2) to assess the motives for the practice. Independent t-test were executed to compare the motives between the 2 groups and d Cohen was executed for effect size. We found that some motives were significantly higher in exercise at gyms compared to nature and adventure sports, namely Health Avoidance (p = 0.001; d = 1.27), Health Pressures (p = 0.001; d = 0.76), Positive Health (p = 0.001; d = 1.09), Strength & Endurance (p = 0.001; d = 1.02) and Nimbleness (p = 0.001; d = 0.80). These results are in line with previous studies suggesting that the pursuit of health benefits is usually most identified by physical exercise practitioners. These studies are important to create different motivational profiles which may have an impact in the practice (and in the avoidance of withdrawals) in physical activity practice. Keywords: Exercise at gyms; Nature and adventure sports; Motivation.
- Exploring Lifestyle Habits, Physical Activity, Anxiety and Basic Psychological Needs in a Sample of Portuguese Adults during COVID-19Publication . Antunes, Raul; Frontini, Roberta; Amaro, Nuno; Salvador, Rogério; Matos, Rui; Morouço, Pedro; Rebelo-Goncalves, RicardoThis cross-sectional study aimed to characterize the lifestyle habits, anxiety levels and basic psychological needs (BPN), in Portuguese adults during the Coronavirus Disease 2019 (COVID-19) pandemic, including a comparison between genders and age groups. In total, 1404 adults (36.4 ± 11.7 years; 69.6% female) answered sociodemographic data and three instruments: the International Physical Activity Questionnaire, the Basic Need General Satisfaction Scale and the State-Trait Anxiety Inventory. Males revealed higher values for the total energy expenditure (z = -2.26; p = 0.024; η 2 = 0.004) and for the level of satisfaction of competence (z = -2.62; p = 0.009; η 2 = 0.005). Females showed higher scores for the anxiety state (z = -7.87; p ≤ 0.001; η 2 = 0.044) and anxiety trait (z = -6.49; p ≤ 0.001; η 2 = 0.030). Regarding age, higher values for the anxiety trait (p ≤ 0.001; η H 2 = 0.030) were found in the 18-34 years-old group compared to all the other age groups, also presenting significantly higher values of total energy expenditure (χ² = 13.93; p = 0.008; η H 2 = 0.007) when compared to the 35-44 years-old group. Significant differences were observed between the 18-34 years-old group and the other age groups for the satisfaction of competence (χ² = 40.97; p ≤ 0.001; η H 2 = 0.026), except for the >65 years-old group. Strategies for promoting well-being during periods of social isolation should consider the role of psychological dimensions and lifestyle habits according to the gender or age group.
- Challenges and Innovations in Osteochondral Regeneration: Insights from Biology and Inputs from Bioengineering toward the Optimization of Tissue Engineering StrategiesPublication . Morouço, P.; Fernandes, C.; Lattanzi, W.Due to the extremely high incidence of lesions and diseases in aging population, it is critical to put all efforts into developing a successful implant for osteochondral tissue regeneration. Many of the patients undergoing surgery present osteochondral fissure extending until the subchondral bone (corresponding to a IV grade according to the conventional radiographic classification by Berndt and Harty). Therefore, strategies for functional tissue regeneration should also aim at healing the subchondral bone and joint interface, besides hyaline cartilage. With the ambition of contributing to solving this problem, several research groups have been working intensively on the development of tailored implants that could promote that complex osteochondral regeneration. These implants may be manufactured through a wide variety of processes and use a wide variety of (bio)materials. This review aimed to examine the state of the art regarding the challenges, advantages, and drawbacks of the current strategies for osteochondral regeneration. One of the most promising approaches relies on the principles of additive manufacturing, where technologies are used that allow for the production of complex 3D structures with a high level of control, intended and predefined geometry, size, and interconnected pores, in a reproducible way. However, not all materials are suitable for these processes, and their features should be examined, targeting a successful regeneration.
- The Relationship Between Anxiety Levels, Sleep, and Physical Activity During COVID-19 Lockdown: An Exploratory StudyPublication . Frontini, Roberta; Rebelo-Goncalves, Ricardo; Amaro, Nuno; Salvador, Rogério; Matos, Rui; Morouço, Pedro; Antunes, RaulNowadays and worldwide, the attention is focused on coronavirus disease (COVID-19), and its consequences on mental health are yet to be fully understood. It is important to capture differences in anxiety levels among populations, groups, and the gender-related variation. Therefore, the present study had two main purposes: (1) to characterize the levels of state anxiety and trait anxiety by examining gender-related, sleep-related, and physical activity-related variations in a nonrepresentative sample of the Portuguese population during the first weeks of lockdown; and (2) to explore the possible relationship between trait anxiety and state anxiety and the possible role of gender as a moderator. This cross-sectional study comprised 1,332 Portuguese adults (aged 18–55 years old) recruited online during COVID-19 outbreak measures. Participants answered to sociodemographic data and the Portuguese version of the State-Trait Anxiety Inventory (STAI). Gender differences were found in both state anxiety (p = < 0.001; d = 0.385) and trait anxiety (p = < 0.001; d = 0.467) with females presenting higher values. People reporting doing more physical activity than usual during COVID-19 lockdown presented lower levels of state anxiety (p = < 0.001; d = 0.200). People reporting more satisfaction with the quality of sleep presented lower levels of both state anxiety (p = < 0.001; d = 0.701) and trait anxiety (p = < 0.001; d = 0.899). Variation associated with the physical activity level (low, moderate, and high) was significantly different among groups in both state anxiety (p = < 0.001) and trait anxiety (p = < 0.001). When analyzing in more detail separating the levels of physical activity, participants performing moderate and high physical activity showed lower values of state and trait anxiety compared to participants with low physical activity. Participants performing high physical activity also showed lower values of state anxiety compared to participants performing moderate physical activity. Higher levels of trait anxiety were related to higher levels of state anxiety, but this association was not moderated by gender. Interventions aiming to support people psychologically during this outbreak should consider anxiety as well as gender and possible behavioral changes in sleep and physical activity, for example. Health professionals should not only consider the anxiety related to the situation we are living but also address trait anxiety to help overcome COVID-19 psychological consequences.
- Higher Physical Activity Levels May Help Buffer the Negative Psychological Consequences of Coronavirus Disease 2019 PandemicPublication . Antunes, Raul; Goncalves-Rebelo, Ricardo; Amaro, Nuno; Salvador, Rogério; Matos, Rui; Morouço, Pedro; Frontini, RobertaThis study explored the associations between physical activity (PA) anxiety levels, and the perception of satisfaction of basic psychological needs (BPN), during Coronavirus Disease 2019 (COVID-19) lockdown. Thus, 1,404 participants (977 women, 426 men, and one respondent preferred not to answer) ranging from 18 to 89 years old (36.4 ± 11.7 year-old) completed a questionnaire in the period between 1st and 15th April 2020. The survey included sociodemographic data and the following validated instruments: the International Physical Activity Questionnaire (IPAQ), the Basic Need General Satisfaction Scale and the State-Trait Anxiety Inventory. The Kruskal-Wallis test was performed to examine variation in anxiety levels and BPN satisfaction according to PA category (low, moderate, and high). Spearman’s Rho correlations coefficients were used to determine the association between anxiety levels and psychological needs. Individuals presenting a higher level of PA revealed lower levels of anxiety-state (H = 20.14; p < 0.01). Differences between elements from different levels of PA were found for the autonomy (H = 23.52; p < 0.001), competence (H = 18.89; p < 0.001), and relatedness (H = 24.42; p < 0.001) psychological needs, suggesting that those who feel their BPN as more satisfied have higher levels of PA. The study found statistically significant correlations between anxiety-state and the satisfaction of the needs for autonomy (p = 0.01; r = −0.46), competence (p = 0.01; r = −0.40), and relatedness (p = 0.01; r = −0.21). These findings support the importance that PA has in the anxiety levels during social isolation, emphasizing the importance of multidisciplinary teams in an individual-based approach.
- Wall Drop Punt Kick & Catch: Contributions towards the creation of a new gross manipulative coordination testPublication . Matos, Rui; Monteiro, Diogo; Rebelo-Goncalves, Ricardo; Coelho, Luís; Salvador, Rogério; Antunes, Raul; Mendes, Diogo; Amaro, NunoThis study aimed to search for age and sex differences on a manipulative eye-segmental (hand and foot) coordination task. It represents the first step towards a possible creation of a manipulative eye-hand and eye-foot coordination test that may be used in motor competence test batteries. One hundred and sixty-eight children (85 boys and 83 girls), with a mean age of 12.79 years old (+-1.56) were assessed. Subjects had 30 seconds to achieve as many ball impacts as possible on a front wall (two meters apart), following a drop punt kick, rebound on the wall and catch sequence. Compared to girls’, boys’ performance was significantly better (p <.001) on each studied age (10, 11, 13 and 14), with large effect sizes (all four Cohen’s d values over 1.30). Besides, 10 and 11 years-old subjects’ performance, both in boys and in girls, was significantly lower than their 13 and 14 years-old subjects’ counterparts (p <.001, except for the comparison between 13 and 14 years-old subjects, on girls, where p <.01). All related effect sizes were large (all Cohen’s d values over 1.03). Results confirm literature, as boys’ performance on this manipulative task was significantly better than girls’ one. The results seem to be promising about the possible use of the task in question as an eye-hand and eye-foot coordination test in future. Further research needs to be performed, namely aiming its validation (testing its reliability and concurrent validity).
- O comportamento do consumidor no mercado fitness: físico x virtualPublication . Eloisa Mello, Mariane; Curth, Marcelo; Albornoz Gonçalves, Manuela; Salvador, RogérioA sobrevivência do profissional de Educação Física, bem como as empresas do mercado fitness, frente a eventos adversos externos, impostos de forma abrupta por uma nova realidade decorrente da pandemia de COVID-19, expôs a fragilidade das relações comerciais com seus alunos/clientes, comprometendo as receitas e forçando-os a se reinventar e adaptar-se às novas modalidades de atendimento. Entendendo que a percepção de valor, confiança, necessidade de interação afetam a intenção de compra do consumidor, este artigo tem como objetivo verificar esta influência no mercado fitness de modo comparativo ao ambiente de entrega do serviço: estabelecimentos com serviços físicos x virtuais. Foi realizado um estudo do tipo survey com 161 alunos/clientes de academias. A técnica estatística utilizada foi Modelagem de Equações Estruturais (MEE), por meio da qual o modelo conceitual foi testado. Os resultados destacam a percepção de que o consumo em lojas físicas obtém uma resposta emocional positiva visando à intenção de compra por parte do consumidor, visto que valoriza bastante a interação humana, gerando sentimentos de alegria, satisfação e bem-estar, sendo sensível tanto ao preço comportamental como o monetário. Indicam maior percepção de qualidade e confiança na compra de serviços/produtos em ambientes físicos quando comparado à venda no formato virtual, considerando a necessidade de interação do aluno/cliente com o profissional de Educação Física.
- Qualidade de vida, vitalidade e força de preensão manual em idosos praticantes de exercício físicoPublication . Antunes, R.; Fonseca, E.; Oliveira, D.; Matos, Rui; Amaro, Nuno; Morouço, P.; Coelho, Luís; Rebelo-Goncalves, R.O envelhecimento está associado a patologias crónicas, que podem ser prevenidas ou retardadas através do envolvimento em comportamentos saudáveis, como a prática regular de Exercício Físico (EF). O objetivo deste trabalho foi caracterizar a qualidade de vida, vitalidade e força de preensão manual de idosos participantes em programas comunitários de EF, bem como analisar a relação da prática de EF com estas variáveis. Recorreu-se a uma amostra composta por 81 indivíduos, 49 do sexo feminino e 32 do sexo masculino, com idades compreendidas entre os 65 e os 85 anos (72.33±5.02). Os resultados indicam-nos que os elementos do género masculino apresentavam valores superiores nas variáveis força de preensão manual (p<0.001; 𝜂!=0.510), vitalidade subjetiva (p=0.05; 𝜂!=0.005) e no domínio “intimidade” da qualidade de vida (p=0.01; 𝜂!=0.005). Relativamente à análise das relações entre as variáveis, no género feminino a força de preensão manual está relacionada com a frequência semanal (r=0.42; p=0.003), com o número de horas de prática (r=0.49; p<0.001), e com a qualidade de vida geral (r=0.35; p=0.015). Ainda no género feminino, verificamos a existência de uma regressão linear significativa da frequência de prática semanal (R2 ajustado=0.23; p<0.001) e do número de horas semanal (R2 ajustado=0.30; p<0.001), com a força de preensão manual. Já no género masculino, a força de preensão manual correlaciona-se com o número de horas de prática semanal (r=0.38; p=0.033). Já a vitalidade está relacionada com a força de preensão manual (r=0.49; p=0.004) e com a qualidade de vida geral (r=0.61; p<0.001). Parece assim evidente o papel do EF por parte desta população, bem como a inclusão do treino de força uma vez que esta variável parece estar associada a uma melhor perceção de qualidade de vida e de vitalidade pelo idoso.
