High-intensity functional training (HIFT) is characterized by presenting high volumes and training intensities with constantly varied exercises. The aim of this study was to analyze the internal training load and the effects of high-intensity functional training on physical performance in subjects with different training volumes and frequencies. A total of 31 volunteers involved in high-intensity functional training (14 men and 17 women) were divided according to their training volumes and frequencies (high training-volume and frequency—HTVF; (n = 17) (nine women and eight men; age: 31.0 ± 6.3 years; height: 168.8 ± 8.1 cm, body weight: 73.6 ± 11.9 kg; BMI: 25.96 kg/m2) and moderate training volume and frequency—MTVF; (n = 14) (eight women and six men; age: 26.6 ± 4.7 years; height: 167.2 ± 8.6 cm, body weight: 75.8 ± 18.0 kg; BMI: 27.33 kg/m2)). The internal training load was determined using the session-rating of perceived exertion method. The monotony index (MI) and training strain (TS) were used to determine training variability during the training weeks. Countermovement vertical jump height, 20-m sprinting and handgrip strength were assessed at baseline and after six weeks of training. There was a time effect for MI ((F(5, 145) = 5.942; p = 0.0001)), TS ((F(5, 145) = 5.734; p = 0.0001)), weekly internal training load ((F(4.006, 116.87) = 4.188; p = 0.003)) and mean weekly internal training load ((F(4.006, 116.87) = 4.188; p = 0.003)). There was no increase in performance in either group for countermovement vertical jump height ((F(1,29) = 6.081; p = 0.050)), sprinting ((F(1,29) = 1.014; p = 0.322)), right handgrip strength ((F(1,29) = 2.522; p = 0.123)) or left handgrip strength ((F(1,29) = 2.550; p = 0.121)). The current findings suggest that six weeks of high-intensity functional training was not able to increase performance in either group. Therefore, different volumes and frequencies do not seem to influence the increase in physical performance of HIFT practitioners.

INTRODUÇÃO: Atualmente o desempenho esportivo tem se desenvolvido de forma rápida e concreta, exigindo, dessa forma, uma eficiente evolução das diferentes áreas das ciências do esporte, oferecendo o suporte cientifico necessário à continuidade desse fenômeno. OBJETIVO: O estudo em questão teve como objetivo desenvolver uma equação matemática preditora de idade óssea de jovens atletas, com base em variáveis antropométricas. MÉTODOS: Para se alcançar o resultado final foram medidas dobras cutâneas, perímetros corporais e diâmetros ósseos, idade cronológica e idade óssea. O tratamento estatístico utilizou a correlação entre as variáveis, a regressão linear múltipla com modelagem backward. RESULTADO: Se obteve como resultado final um modelo de equação que explica 75,4% da variação da idade óssea com r = 0,868 e R² = 0,754, utilizando idade cronológica, estatura, dobra tricipital, perímetro corrigido de braço e diâmetros de fêmur e úmero. CONCLUSÃO: Concluiu-se a partir dos resultados, que esse tipo de modelo revela valores aproximados aos observados através da radiografia de mão e punho, tornando-se importante na observação do estágio maturacional através de testes de fácil aplicabilidade por profissionais da área esportiva.

Resumo: O avanço das neurociências na educação aborda aspectos da memória, da aprendizagem e da indissociável relação corpo-mente para aprendizagem do sujeito. Este estudo buscou correlacionar tais conceitos às Dificuldades de Aprendizagem (DA) específicas em cálculo (aritmética) e pressupostos da Educação Matemática. O objetivo foi investigar o impacto de um programa pedagógico, com atividades didático-manipulativas usando corpo/movimento, em um estudo longitudinal com 37 escolares com indicativos de DA em cálculo, entre 7 e 12 anos, oriundos de um colégio privado em Cuiabá, MT. Como resultado, houve um aumento no desempenho escolar da amostra, mostrando que o uso do corpo e de atividades somatossensoriais podem auxiliar alunos com DA a focarem a atenção e melhorar sua autonomia acadêmica, senso de autoeficácia e compreensão matemática. A indissociabilidade corpo-mente e a realização bem-sucedida do presente estudo confirmam a necessidade de se promoverem pesquisas em experiências e aprendizagem motoras para minimizar impactos das DA.Palavras-chave: Neurociência.

Abstract:The advancement of neurosciences in education presents aspects of memory, learning and the inseparability of the body-mind relationship in the learning of students. This study sought to correlate these concepts with Learning Disabilities (LD) specifically in arithmetic and principles of Mathematics Education. The purpose was to investigate the impact of an educational program with didactic and manipulative activities using movement-body in an experimental typology study with 37 students (of a private college in Cuiabá, MT, Brazil) between 7 and 12 years old with indicative of LD in calculus. The main result was the increase of the academic results of the students, showing that the use of the body and somatosensory activities can help students with LD to focus attention and improve their academic autonomy, sense of self-efficacy and mathematical understanding. Believing in the inseparability of the body-mind relationship and in the positive outcome of this study we conclude the need to promote research in motor learning to minimize impacts of LD.

RESUMOO presente estudo centra-se em verificar a influência da maturação na antropometria e aptidão física de jovens praticantes de voleibol, observando a correlação do estado maturacional com as demais variáveis. A amostra do estudo foi composta por 149 sujeitos (n= 149) de 8 a 14 anos. Para verificação da maturação, utilizou-se a idade cronológica e idade óssea como preditor maturacional através do método Grave-Brown (1976). Por sua vez, para as variáveis antropométricas, foram usadas as medidas de massa, estatura, índice ponderal, diâmetros biacromial e bi-crista ilíaca, perímetros de braço e perna, e perímetros de braço e de perna corrigidos, além dos testes físicos de agilidade, coordenação e força explosiva de membros inferiores e superiores. Ao observar a correlação entre a maturação e as demais variáveis, constatou-se que, no feminino, apenas o índice ponderal não apresentou correlação significativa e, no masculino, o índice ponderal, agilidade e coordenação. Em ambos os sexos, a estatura e diâmetros biacromial e bi-crista ilíaca apresentaram bons resultados. Assim, o estudo permite concluir que existe correlação entre o estágio maturacional, a variável força e variáveis antropométricas, ressaltando, ainda, a importância da avaliação de diferentes variáveis ao se trabalhar com orientação e promoção de talentos no desporto. Palavras-chave: idade óssea, morfologia, desporto ABSTRACTThe aim of this study was to verify the influence of maturation in anthropometry and physical valences of young volleyball players, assessing the correlation between maturational state and other variables. The sample was composed of 149 children between 8 and 14 years. Chronological age and bone age as maturational predictor with the method of Grave-Brown (1976) were selected to assess the maturation state. As anthropometrics weight, height, ponderal index, biacromial diameter and bi-iliocristal diameter, perimeter of arm and leg, and perimeter of leg fixed were measured. In addition, it was also assessed the physical agility tests, coordination and explosive force of lower and upper limbs. All but ponderal index presents significant correlation with maturational state in girls. For boys, all correlations were significant except the ponderal index, agility and coordination. In both genders, the height and biacromial and bi-iliocristal diameter presented strong associations, allowing us to complete a correlation in maturational stage with the variable strength and anthropometric variables, as well as allows us to confirm the importance of evaluation from different variables when working with guidance and promotion of talent in the sport.

The Cerebral Vascular Accident is responsible for a significant increase in the mortality rate in individuals who have suffered this condition, regardless of the level of subsequent disability. This study aimed to analyze the influence of a strength training program on indicators of depression in survivors of the ischemic stroke. The study sample included subjects from both genders who were divided into two groups: an experimental group (EG) consisting of 11 subjects aged 51.7 8.0 years, and a control group (CG) consisting of 13 subjects aged 52.5 7.7 years. The EG underwent 12 weeks of strength training. Assessment was made in the pre-test before training and at the re-test after 12 weeks of training. We used the Beck Depression Inventory and evaluated 1RM. Significant differences in depression were found between post-test and pretest measurements (Δ% = −21.47%, p = 0,021) in the EG; furthermore, there were significant differences in all indicators of depression between the EG and CG after completing 12 weeks of training. There were significant gains in strength of the EG in relation to the CG. There was a negative correlation between the strength gains as determined with the 1RM test and the levels of depression, especially in lower-limb exercises. The results of this study suggest that improvements in strength are negatively correlated with levels of depression. Improvements in strength are therefore associated with a reduction in levels of depression.

The measures were compared between the two groups using the Student t-test for independent samples. Discriminant function analysis was applied to predict group allocation using the measures obtained as independent variables. The two groups differed significantly in terms of body weight, fat mass, height, maximum attack height, range of attack, and somatotype. Discriminant function analysis identified the somatotype measures (endomorphy, ectomorphy, and mesomorphy) with correlation coefficients below 0.30. The canonical correlation coefficient obtained with this function was 0.856. In conclusion, somatotype or vertical jump ability does not seem to distinguish elite athletes from non-elite athletes in under-17 female volleyball players, and height is the main morphological determinant to achieve elite level performance.
