Efecto de 24 sesiones de entrenamiento de fuerza en un paciente con gonartrosis bilateral: a propósito de un caso / Efeitos de 24 sessões de treinamento de força em um paciente com gonartrose bilateral: um estudo de caso / Effect of 24 sessions of resistance training in a patient with gonarthrosis bilateral: a case study

Objetivos. Evaluar los efectos de 24 sesiones de ejercicio de fuerza (EF) progresivo, de intensidad moderada/alta sobre la capacidad funcional, la fuerza muscular y la composición corporal de un anciano con gonartrosis (GA) bilateral. Método. La capacidad funcional, la fuerza muscular y las variables antropométricas fueron medidas antes y después de 24 sesiones de entrenamiento. El paciente realizó el EF progresivo entre 8 y 12 repeticiones máximas, utilizando los principales grupos musculares de los miembros superiores e inferiores, 2 veces por semana durante 12 semanas. Resultados. Hubo una mejora en el test de sentarse y levantase (46,1%), en el sentar y alcanzar (33,3%), así como un aumento de la fuerza muscular en todos los ejercicios analizados y mejora de los índices antropométricos. Conclusión. Los resultados de este estudio indican que 24 sesiones de EF progresivo pueden ser eficaces en la mejora de índices antropométricos, la capacidad funcional y la fuerza muscular de un paciente anciano diagnosticado de GA bilateral (AU)

Objective. To evaluate the effects of 24 moderate-high intensity progressive Resistance Training (RT) on functional capacity, muscle strength and body composition in an elderly patient with gonarthrosis (GA) bilateral. Methods. Functional capacity, muscle strength and anthropometric variables were measured before and after 24 training sessions. The patient performed a 12-weeks progressive RT (2 times/week), between 8 and 12 repetitions maximum, using the major muscle groups of the upper and lower limbs. Results. There was an improvement in the sit-to-stand test (46,1%), in sit and reach test (33,3%), the muscle strength increased in all exercises analyzed and the anthropometric indices enhanced. Conclusion. The results of this study indicate that 24 sessions of progressive RT, can be effective in improving anthropometric indices, functional capacity and muscle strength of elderly patients diagnosed with GA bilateral (AU)

Objetivo: Avaliar os efeitos de 24 sessões de treinamento de força (TF) progressivo de intensidade moderada/alta sobre a capacidade funcional, força muscular e composição corporal de um idoso diagnosticado com gonartrose (GA) bilateral. Métodos: A capacidade funcional, força muscular e as variáveis antropométricas foram avaliadas antes e após 24 sessões de treinamento. O paciente realizou o TF progressivo entre 8-12 repetições máximas, utilizando os principais grupamentos musculares dos membros superiores e inferiores, duas vezes por semana, durante 12 semanas. Resultados: Ocorreu melhora no teste de sentar e levantar (46,1%), teste de sentar e alcançar (33,3%), assim como, os índices antropométricos e níveis de força aumentaram em todos os exercícios realizados. Conclusão: Os resultados deste estudo indicam que 24 sessões de TF progressivo podem ser eficazes na melhora dos índices antropométricos, capacidade funcional e força muscular de um paciente idoso diagnosticado com GA bilateral

Time and frequency analysis of the static balance in young adults with Down syndrome.

The main objective of this study is to understand the differences in equilibrium control between normal subjects and those with Down syndrome. A total of 54 subjects participated voluntarily, divided into control group and Down syndrome group. The equilibrium of the subjects was tested under two conditions: bipedal support with eyes open and closed. The signals were analyzed in a time and frequency domain. The statistical parameters selected (i.e., RMS distance, mean velocity, mean frequency and sway area) to analyze the behavior of the center of pressures (CoP) are calculated employing the result of the combination of the time series data in both directions (i.e. resultant distance). In order to calculate the frequency bands produced by the displacements of the CoP, a Fast Fourier Transform of the data was performed. The group with Down syndrome showed poorer static equilibrium control than the control group in the time domain. In the frequency domain, we found differences between the groups in the distribution of energy in the frequency bands analyzed. In addition, we observed the existence of an interaction effect of the group and the condition tested (p<0.001). These findings show that in the absence of visual information, the control group increases the energy at low frequencies, while the group with Down syndrome decreases it. Additionally, the lower amount of energy observed in this band under the 'eyes closed' condition may serve to identify abnormalities in the functioning of the vestibular apparatus of individuals with Down syndrome and/or difficulties experienced by these individuals in extracting relevant information from this route.
