“…Our findings are in accordance with the results of the Melchiorri et al 13 study which investigated neuromuscular changes induced by fatiguing exercise performed with elastic resistance compared to constant load. The constant load equipment used was built by the authors themselves to perform the elbow flexion exercise.…”

“…In addition, push-ups with elastic resistance are versatile and can be carried out in multiple locations with different intensity settings. Adding strength to electromyographic signals can be an important inferential tool to evaluate physiological aspects of muscular system and its implications on strenght improvements 12,13 . Thus, future studies should include the analysis of muscle strength in results.…”

“…Several authors use SEMG to analyze the behavior of localized muscular fatigue [9][10][11] and many of them have used this tool, adding value to the discussion about neuromuscular behavior during exercises with different types of resistance 12,13,15 . However, there is no consensus on the effectiveness using different resistance methods and their neuromuscular adaptations, since most of these studies assess various types of populations.…”

| The present study sought to investigate the electromyographic parameters of muscle fatigue during dynamic exercise conducted with variable resistance (elastic) and fixed resistance (pulley). Ten trained men participated voluntarily in the study. Two maximum voluntary isometric contractions (MVIC) of the elbow flexors were performed for 5 seconds and a two minutes interval rest was given between reps. Then, the volunteers performed unilateral elbow flexion repetitions until the exhaustion using fixed and elastic resistance with a pre- codo hasta sentirse cansados, y emplearon la resistencia fija y elástica con ritmo prestablecido de dos segundos para cada fase del movimiento. Se llevó a cabo la resistencia constante en la polea a 30% de la CVIM. Relativo a la resistencia elástica, el control de carga se basaba en una percepción subjetiva del esfuerzo empleado por el participante. El orden del ejercicio fue aleatorio, y se registró la señal electromiográfica del músculo bíceps durante las contracciones. Desde la señal electromiográfica relativa a cada ejecución del movimiento se dibujó rectas de regresión lineal para las variables RMS y la frecuencia de potencia media (FPM). Se confirmó las inclinaciones de rectas normalizadas por el coeficiente lineal de las ecuaciones de regresión a través de la prueba t pareada. No se observaron diferencias significantes entre los tipos de resistencia (elástica y polea). Los estándares electromiográficas de fatiga durante la práctica de ejercicios de flexión de codo empleando resistencia elástica y polea no fueron distintos. La percepción del esfuerzo durante la práctica de ejercicio con elástico no trae consecuencias al estándar de señal electromiográfico (RMS y FPM).

RESUMOO objetivo deste estudo foi analisar os efeitos do treinamento resistido com tubos elásticos e aparelhos de musculação (convencional) sobre a força muscular, qualidade de vida e dispneia em pacientes com doença pulmonar obstrutiva crônica (DPOC). Pacientes alocados em grupos de treinamento com tubos elásticos (ETG, n=9) e convencional (CRG, n=10) foram avaliados por força isométrica e questionários de qualidade de vida (CRQ) e dispneia (MRC). A força isométrica aumentou em ~25% em ambos os grupos em todos os movimentos (p<0,05). MRC e o domínio dispneia de CRQ apresentaram melhoras de -28,70% e -6,05 % no ETG, e -33,33% e -16,23% no CRG, respectivamente. Força de flexão de ombro e cotovelo apresentaram correlação negativa com a variável MRC (p<0,05) para CRG. Ambas intervenções foram benéficas para aumento da força e redução do MRC, com aumento da força de membros superiores correlacionado à redução da sensação de dispneia nos pacientes com DPOC.

ABSTRACTThe objective of this study was to analyze the effects of resistance training with elastic tubes and weight machines (conventional) on muscle strength, quality of life and dyspnea in patients with chronic obstructive pulmonary disease (COPD). Patients were allocated in training groups with elastic tubes (ETG, n = 9) and conventional (CRG, n = 10) and evaluated by isometric strength and quality of life questionnaire (CRQ) and dyspnea (MRC). Isometric strength increased by ~25% in both groups in all movements (p <0.05). MRC and the CRQ dyspnea domain showed improvement of -28.70% and -6.05% in the ETG, and -33.33% and -16.23% at CRG, respectively. Shoulder and elbow flexion showed a negative and significant correlation with MRC (p <0.05), for CRG. Both interventions were beneficial for increasing the strength and reducing the MRC score, and increased strength of upper limbs correlated to the reduction of the sensation of dyspnea in patients with COPD.
