Proprioceptive neuromuscular facilitation and strength training to gain muscle strength in elderly women

Abstract

Introduction:The world population is aging, and this leads to progressive physiological changes and increased incidence of acute and chronic degenerative diseases. In this sense, one of the main changes occurring during this period is sarcopenia, characterized by decreased skeletal muscle mass. Objective: To perform comparative analyze of results of proprioceptive neuromuscular facilitation (PNF) techniques and strength training to gain muscle strength of biceps and quadriceps and grip in the elderly. Method: This is a prospective randomized study with purposive sample of 17 elderly patients undergoing a program of strength training and evaluation with a dynamometer, before and after applying the treatment protocol. After evaluation, subjects were randomly divided into two groups: PNF and Bodybuilding. Results: The group trained with PNF had more significant gain in muscle strength, biceps (p=0.0392*) and quadriceps (p=0.0230*) did not show statistically significant relevance in the grip (p=0.1075). In the group trained with weights there was no statistically significant difference: biceps (p=0.5338), quadriceps femoris (p=0.0679) and palmar (p=0.3758). Comparing both techniques, however, there was no statistical difference: biceps (p=0.5739), quadriceps (p=0.8450) and palmar (p=0.2457). Conclusion: This study showed that the period of 12 weeks of intervention seems to be sufficient to achieve gains in muscle strength with PNF technique, but when comparing the two techniques it was not statistically significant. ResumoIntrodução: A população mundial está envelhecendo, o que acarreta alterações fisiológicas progressivas e aumento da incidência de doenças agudas e crônicodegenerativas. Nesse sentido, uma das principais alterações que ocorre nesse período é a sarcopenia, caracterizada pela diminuição da massa muscular esquelética. Objetivo: Analisar comparativamente os resultados das técnicas de Facilitação Neuromuscular Proprioceptiva (FNP) e musculação para ganho de força dos músculos bíceps braquial e quadríceps femoral e preensão palmar em idosas. Método: Trata-se de estudo prospectivo, randomizado com amostra intencional de 17 idosas submetidas a um programa de treinamento de força e avaliação com dinamômetro, antes e após aplicação do protocolo de tratamento. Após a avaliação, os indivíduos foram divididos aleatoriamente em dois grupos: FNP e Musculação. Resultados: O grupo treinado com FNP apresentou ganho de força mais expressivo no músculo, bíceps braquial (p=0,0392*) e quadríceps femoral (p=0,0230*), não apresentando relevância estatística significante na preensão palmar (p=0,1075). No grupo treinado com musculação, não houve diferenças estatisticamente significantes: bíceps braquial (p=0,5338), quadríceps femoral (p=0,0679) e na preensão palmar (p=0,3758). Na comparação entre as duas técnicas, porém, não foram observadas diferenças estatísticas: bíceps (p=0,5739), quadríceps (p=0,8450) e preensão palmar (p=0,2457). Conclusão: O presente estudo demonstrou que o período de 12 semanas de intervenção parece s...

Comparison of different neuromuscular facilitation techniques and conventional physiotherapy in knee osteoarthritis

“…At the same time, the current literature also suggests that the combined application of concentric, eccentric, and isometric exercises should be executed to maximize muscle strength [17][18][19]. In some previous studies, improvement in muscle strength was achieved with the application of the PNF methods, which was depicted in our study as well [20][21][22]. Our study results reflected that the improvement in muscle strength could be achieved with PNF training, unlike other prior studies [23,24].…”

Efecto de la técnica “contracciones repetidas” sobre la fuerza del músculo dorsal ancho

“…Los hallazgos de este estudio pueden estar relacionados con el hecho de que este entrenamiento implica varias articulaciones y grupos musculares por su componente en diagonal, lo cual, conduce a un aumento en la estimulación cortical y facilita la contracción muscular, mejora el control motor y genera mayor conciencia en el movimiento (Ferreira, Mendes, Uchôa & Veiga, 2014;Moreira et al, 2017).…”

“…The studies developed in (Branco et al, 2015;Cesário et al, 2014;Chaves et al, 2017;Gomes et al, 2015;Mallmann et al, 2015;Oliveira et al, 2016;Preto et al, 2016;Silva, Pin, & Silva Filho, 2015;Teixeira et al, 2016;Vagetti et al, 2015;Victor et al, 2014) presented scientific evidences about educational actions in health for older adults' health promotion. Some papers were selected, in which quality of life and promotion of healthy aging as resulting factors of strategies in education in health were perceived.…”

“…Many physical and psychosocial benefits resulting from the regular practice of physical activity are reported in the literature (Cesário et al, 2014;Chaves et al, 2017;Preto et al, 2016;Silva, Pin, & Silva Filho, 2015;Teixeira et al, 2016;Vagetti et al, 2015). These include: (i) increased muscle strength, (ii) improved cardiorespiratory capacity, (iii) fat reduction, (iv) increased bone density, (v) improved mood and self-esteem and (vi) the reduction of anxiety and depression.…”
