ABSTRACT

The purpose of this study was to investigate the behavior of foot pronation at different percentages of peak velocity in 23 physically active men. An ergospirometric test was carried out with an initial velocity of 9kmh-1 and increments of 1kmh-1 until exhaustion. 2D kinematic analysis was performed in the posterior frontal plane at all velocities to identify the maximal angle of pronation (MAP) of the right leg. The analyses were performed between the initial periods (0%), 25%, 50%, 75%, and 100% (peak of velocity - PV). All comparisons of the PV phases with the MAP showed an increase in the angle of foot pronation, with the exception of between the start and 25% of PV. Only 4 (∼17%) subjects maintained MAP values within a normal range until PV was reached. Control of the volume and intensity of training, as well as the running technique is suggested and strengthening of the muscles responsible for stabilization of the foot pronation.

ABSTRACT

Sports participation has been referred as having important influence in positive youth development (PYD) in many life-long aspects, as social, physical, physiological and intellectual components. The aim of this study was to verify influences of body size, growth-related changes and age in developmental assets. This cross-sectional design study considered 45 male adolescent basketball players aged 13.6 ± 1.5 years. Participants were engaged in a club structured training program and competed at state level competition, supervised by the Federacao Paulista de Basketball (Sao Paulo's state basketball Federation). There was substantial variation between athletes for all variables. Inspection of credible intervals showed a substantial variation in body size and functional capacity indicators between players grouped by age group and by maturity status. However, substantial variation by both age group or maturity status was present for DAP dimensions. No relation was observed between DAP dimensions with body size and functional capacity, partitioning the substantial variation between players by age group and maturity status. In the present study there was no substantial variation in developmental assets of adolescent basketball players by age or estimated maturity status. Also, from a multidimensional perspective, there was no influence of body dimensions and functional capacities with developmental assets


Se ha mencionado que la participación deportiva tiene una influencia importante en el desarrollo positivo de la juventud (PYD) en muchos aspectos de la vida, como componentes sociales, físicos, fisiológicos e intelectuales. El objetivo de este estudio fue verificar las influencias del tamaño corporal, los cambios relacionados con el crecimiento y la edad en los activos de desarrollo. Este estudio de diseño transversal incluyó a 45 jugadores adolescentes de baloncesto de 13.6 ± 1.5 años. Los participantes se involucraron en un programa de entrenamiento estructurado en clubes y compitieron en una competencia a nivel estatal, supervisada por la Federação Paulista de Basketball (Federación estatal de baloncesto de São Paulo). Hubo una variación sustancial entre los atletas para todas las variables. La inspección de intervalos creíbles mostró una variación sustancial en el tamaño corporal y los indicadores de capacidad funcional entre los jugadores agrupados por grupo de edad y por estado de madurez. Sin embargo, una variación sustancial por grupo de edad o estado de madurez estuvo presente para las dimensiones DAP. No se observó ninguna relación entre las dimensiones de DAP con el tamaño corporal y la capacidad funcional, dividiendo la variación sustancial entre jugadores por grupo de edad y estado de madurez. En el presente estudio no hubo una variación sustancial en los activos de desarrollo de los jugadores de baloncesto adolescentes por edad o estado de madurez estimado. Además, desde una perspectiva multidimensional, no hubo influencia de las dimensiones corporales y las capacidades funcionales con los activos de desarrollo


A participação esportiva tem sido referida como uma importante influência no desenvolvimento positivo de jovens (PYD) em muitos aspectos ao longo da vida, tais quais componentes sociais, físicos, psicológicos e intelectuais. O objetivo deste estudo foi verificar influências do tamanho corporal, mudanças relacionadas ao crescimento e idade nos ativos de desenvolvimento. Esse estudo de desenho transversal considerou 45 adolescentes do sexo masculino jogadores de basquete de 13.6 ± 1.5 anos. Os participantes estavam engajados em um programa de treinamento de clube estruturado e competiam no nível estadual, supervisionado pela Federação Paulista de Basketball (Federação estadual de São Paulo). Não houve variação substancial entre os atletas para todas as variáveis. A observação dos intervalos de confiança mostrou uma variação substancial nos indicadores de tamanho corporal e capacidade funcional entre os jogadores agrupados por grupo etário e estágio de maturação. Entretanto, uma variação substancial foi encontrada tanto pelo grupo etário quanto para o estágio de maturação nas dimensões do DAP. Não foi observada relação entre as dimensões do DAP com o tamanho corporal e capacidade funcional, considerando a variação substancial entre os jogadores por agrupamentos grupo etário e estágio de maturação. No presente estudo, não houve variação significativa nos ativos de desenvolvimento de jogadores de basquete pela idade e nem pelo estágio maturacional estimado. Também, pela perspectiva multidimensional, não houveram influências do tamanho corporal e das capacidades funcionais com os ativos de desenvolvimento

ABSTRACT

Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women. The aim of the present study was to understand the effects of closed kinetic chain exercises with constant load on muscular strength, the knee torque conventional ratio (hamstring:quadriceps - H:Q), and functional capacity in the elderly. Nine untrained healthy elderly women participated in experimental resistance training. Ten-repetition maximum (10RM) for the deadlift, isokinetic maximum voluntary concentric contraction, and functional capacity were assessed before and after the 7-week resistance-training program. Magnitude based inference analysis was used to examine the differences in muscle strength and functional performance. Therefore, the smallest worthwhile change was calculated and 90% confidence intervals were also determined to characterize muscle strength and functional performance. The analysis demonstrated an increase in the deadlift and knee flexor torque (60o/sec) after the experimental intervention. Furthermore, stair ascent, knee extensor torque (120o/sec), knee flexor torque (120o/sec), and knee ratio (60o/sec) also presented a positive effect in the same training period. Conversely, knee extensor torque (60o/sec), and knee ratio (120o/sec) did not show conclusive responses. In conclusion, resistance training with functional closed kinetic chain exercises and constant volume load (i.e., 65% of 1-repetition maximum) can increase deadlift 10RM, isokinetic concentric torque, the conventional H:Q ratio, and stair ascent performance in elderly women.

ABSTRACT

Introdução: Reconhece-se que o diabetes é uma doença que, independentemente da faixa etária e da etiologia, causa impac-to negativo que compromete a qualidade de vida. A avaliação da qualidade de vida de indivíduos com doenças crônicas tem sido objeto de investigação na área da saúde, sendo considerada importante indicador dos resultados terapêuticos em diferentes situações clínicas. Objetivo: Realizar uma revisão integrativa apresentando os instrumentos utilizados para a avaliação da qualidade de vida em indivíduos com diabetes mellitus. Ma-teriais e Métodos: Foi realizada revisão integrativa nas bases de dados MEDLINE, LILACS, SCIELO, relativo aos anos de 2009 a 2017, utilizando os descritores: Diabetes Mellitus, Qua-lidade de Vida e Avaliação. Resultados: Foram selecionados sete artigos que em suas metodologias apresentaram quatro instrumentos de avaliação da qualidade de vida. Conclusão: As evidências demonstram que não existe uma padronização dos instrumentos em relação a avaliação da qualidade de vida em indivíduos com diabetes mellitus
