Cardiorespiratory fitness and muscular strength of deaf futsal players.

The present study compared the cardiopulmonary exercise capacity and peak torque of the knee extensor and flexor muscles in team players associated with the Gaucho Deaf Futsal Federation players to those of their hearing peers. In this cross-sectional study, 16 male athletes, eight futsal players with hearing impairment (deaf group, DG; 22.6±7.7 years), and eight futsal players with normal hearing (control group, CG; 22.5±2.9 years) underwent a cardiopulmonary test on a treadmill and isokinetic dynamometry at 60°/sec. All athletes were subjected to a cardiopulmonary test on a treadmill and isokinetic dynamometry at 60°/sec. The main results showed a reduction in the cardiorespiratory fitness of deaf athletes when compared to the control group maximal oxygen consumption (VO2max) (40.3±9.8 mL/kg/min vs. 50.7±4.7 mL/kg/min, P= 0.01), oxygen pulse (15.3±4.8 mL/bpm vs. 20.7±2.6 mL/bpm, P=0.01) and ventilation (70.1±22 L/min vs. 96.2±15 L/min, P=0.01), respectively. The relative torque peak of the dominant knee flexors was significantly lower in the deaf group when compared to the control (1.5±0.2 N.m/kg vs. 1.9±0.2 N.m/kg, P=0.004), respectively. There was a significant correlation between VO2max and peak torque of the dominant knee flexors (r s=0.83, P<0.001) and extensors (r s=0.65, P=0.006). When compared to players with normal hearing, deaf players showed lower cardiorespiratory fitness and decreased knee flexor strength. The performance of the thigh muscles was associated with aerobic capacity.

Comparação entre pico de torque e flexibilidade dos membros inferiores de indivíduos com e sem diabetes mellitus tipo 2 / Comparación entre pico de torque y flexibilidad de los miembros inferiores de individuos con y sin diabetes mellitus tipo 2 / Comparison between muscle strength and flexibility of the lower limbs of individuals with and without type 2 diabetes mellitus

RESUMO O objetivo deste trabalho foi comparar o pico de torque e flexibilidade dos membros inferiores de indivíduos com e sem diabetes mellitus tipo 2 (DM2). O método foi o estudo com grupos expostos e não expostos ao DM2. Foram incluídos indivíduos com diagnóstico médico de DM2, encaminhados para eletroneuromiografia, e não expostos ao DM2. Foram excluídos da pesquisa indivíduos com idade superior a 70 anos ou que, por algum motivo, não conseguiram realizar um ou dois dos testes. A amostra foi não probabilística, composta por 64 indivíduos: 34 (53,1%) expostos ao DM2 e 30 não expostos; 50 (78,1%) eram do sexo feminino, a idade média era de 60,7±7,1 anos, e o membro inferior dominante era o direito em 57 (89,1%) dos indivíduos. Comparando indivíduos com e sem diagnóstico de DM2, observou-se redução do torque de flexão à esquerda, em velocidade angular de 120° (25,94±2,26 vs. 33,79±2,4nm, p=0,027, respectivamente). Relatou-se menor valor do torque de dorsiflexão à direita, em velocidade angular de 60°, dos diabéticos em relação aos não diabéticos (10,95±0,89 vs. 13,95±0,96nm, p=0,033, respectivamente). Ao comparar indivíduos com DM2, com e sem diagnóstico de neuropatia diabética periférica (NDP), notou-se maior déficit de flexão entre os indivíduos neuropatas em comparação com não neuropatas (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). Não foram encontradas diferenças estatisticamente significativas ao comparar os grupos de expostos e não expostos ao DM2 e diabéticos neuropatas e não neuropatas.

RESUMEN El objetivo de este trabajo fue comparar el pico de torque y la flexibilidad de los miembros inferiores de individuos con y sin diabetes mellitus tipo 2 (DM2). El método fue el estudio con grupos expuestos y no expuestos al DM2. Se incluyeron individuos con diagnóstico médico de DM2, encaminados para electroneuromiografía, y no expuestos al DM2. Se excluyeron de la investigación a individuos mayores de 70 años o que, por algún motivo, no pudieron realizar una o dos de las pruebas. La muestra fue no probabilística, compuesta por 64 individuos: 34 (53,1%) expuestos al DM2 y 30 no expuestos; 50 (78,1%) eran de sexo femenino, la edad media era de 60,7±7,1 años, y el miembro inferior dominante era el derecho en 57 (89,1%) de los individuos. En comparación con individuos con y sin diagnóstico de DM2, se observó reducción del torque de flexión a la izquierda, en velocidad angular de 120° (25,94±2,26 frente a 33,79±2,4nm, p=0,027, respectivamente). Se ha reportado un menor valor del torque de dorsiflexión a la derecha, en velocidad angular de 60°, de los diabéticos con relación a los no diabéticos (10,95±0,89 frente a 13,95±0,96nm, p=0,033, respectivamente). Al comparar individuos con DM2, con y sin diagnóstico de neuropatía diabética periférica (NDP), se notó mayor déficit de flexión entre los individuos neuropáticos en comparación con no neuropáticos (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). No se encontraron diferencias estadísticamente significativas al comparar los grupos de expuestos y no expuestos al DM2 y los diabéticos neuropáticos y no neuropáticos.

ABSTRACT To compare the muscle strength and flexibility of the lower limbs of individuals with and without T2DM. The method was a study of the types exposed and unexposed to T2DM. Individuals diagnosed with T2DM, individuals referred to electromyography, and those unexposed to T2DM were included. The exclusion criteria were: individuals over 70 years old; those who for some reason failed to complete one or both tests. The study population consisted of 64 individuals; 34 (53.1%) exposed to DM and 30 unexposed, 50 (78.1%) were female, the mean age was 60.7±7.1 and the dominant lower limb was right in 57 (89.1%) individuals. Comparing individuals with and without a diagnosis of DM, one observed a reduction in the flexion torque on the left at a 120 ° angular velocity in diabetics individuals compared with nondiabetic patients, 25.94±2.26 vs 33.79±2, 4nm, p=0.027, respectively. The reduction in dorsiflexion torque on the right, at a 60 ° angular velocity was observed in diabetics compared with nondiabetic patients, 10.95±0.89 vs. 13.95±0.96nm, p=0.033, respectively. When comparing diabetic individuals with and without a diagnosis of PDN, one observed a greater flexion deficit among neuropathic individuals when compared with non-neuropathic individuals, 46.57±9.47 vs 11.63±13.85nm, p=0.049, respectively. No statistically significant differences were found when comparing groups exposed and unexposed to T2DM, and neuropathic and non-neuropathic diabetics.
