Efeitos agudos da utilização de dispositivos geradores de instabilidade externa sobre o desempenho neuromuscular

Abstract

-Physical training with the use of instability generator devices has become popular in the health area, in sport training and clinical practice (mainly in the prevention and treatment of injuries). To understand how the process of using these devices occurs and the results of their acute effects is important to guide professionals in choosing the appropriate device. The aim of this review was to present the main features of instability devices and analyze their acute effects on core muscle activation, neuromuscular performance and activation of lower and upper limbs. Studies have shown that the main acute effects of exercises performed with these devices are: 1) increased activation / muscular recruitment (especially in the middle zone or core); 2) greater co-activation of antagonist muscles (trunk, upper and lower limbs), with increased stiffness and joint stability; 3) lower force output, power and speed in extremities.Key words: Instability; Low pain back; Sports performance. Resumo -O treinamento físico com utilização de dispositivos geradores de instabilidade tem se popularizado na área da saúde, no treinamento desportivo e na prática clínica (principalmente na prevenção e tratamento de lesões). Entender como ocorre o processo de utilização desses dispositivos e quais são os resultados sobre os efeitos agudos é importante para nortear profissionais da área na escolha do dispositivo adequado. O objetivo desta revisão foi apresentar as principais características dos dispositivos desestabilizadores e analisar os efeitos agudos

Cervical and scapular instability in subjects with temporomandibular disorder

“…The flexor and extensor muscles of the neck must stabilize the head and neck to maintain posture and resist dysfunction. It should be considered that the level of optimal muscle activation depends on factors such as the level of individual ability (22) . The neck muscles are considered complex structures with multiple tasks to maintain proper functioning of the cervical spine (23) .…”
