ABSTRACT
OBJECTIVE: To systematically review the literature analyzing the reliability and characteristics of the protocols of isokinetic and isometric evaluation of the trunk flexor and extensor muscles with isokinetic dynamometer. METHODS: This is a systematic review using PubMed, CENTRAL, LILACS, PEDro and SCOPUS databases, searching the oldest records up to December 2019. The risk of bias, the methodological quality and the level of evidence were evaluated using the COSMIN checklist. RESULTS: Fourteen articles have met the criteria and have been included in this study. All the articles performed an isometric or isokinetic evaluation of the trunk muscles with the isokinetic dynamometer and presented an analysis of the protocol's reliability using the intraclass correlation coefficient. Five articles had excellent reliability (0.93-0.98). Most of the studies presented doubtful and inconsistent psychometric values for reliability, because they used a short period between tests. The level of evidence to the fourteen selected articles for reliability was moderate. CONCLUSIONS: Although the studies present limitations in methodological quality, it was possible to identify highly reliable patterns in the parameters employed and to present recommendations for the assessment of trunk flexor and extensor muscles in the isokinetic dynamometer, both for assessment in the sitting position and orthostatic.

The purpose of this study was to investigate the behavior of foot pronation at different percentages of peak velocity in 23 physically active men. An ergospirometric test was carried out with an initial velocity of 9kmh-1 and increments of 1kmh-1 until exhaustion. 2D kinematic analysis was performed in the posterior frontal plane at all velocities to identify the maximal angle of pronation (MAP) of the right leg. The analyses were performed between the initial periods (0%), 25%, 50%, 75%, and 100% (peak of velocity - PV). All comparisons of the PV phases with the MAP showed an increase in the angle of foot pronation, with the exception of between the start and 25% of PV. Only 4 (â¼17%) subjects maintained MAP values within a normal range until PV was reached. Control of the volume and intensity of training, as well as the running technique is suggested and strengthening of the muscles responsible for stabilization of the foot pronation.

Resumo O objetivo deste estudo foi verificar o efeito de um programa de intervenção motora com exergames em crianças com risco e dificuldade significativa de movimento. Foram feitas 18 sessões de 45 minutos. Para identificar aas crianças com risco e dificuldade motora usou-se a bateria MABC-2. Nas análises pré-teste, no grupo experimental havia duas crianças com dificuldade de movimento e crianças com indicativo de risco de dificuldade, nas análises pós-teste verificou-se que apenas duas crianças estavam com risco de dificuldade e quatro sem dificuldade de movimento. Com isso, sugere-se que os exergames podem ser ferramentas úteis para a melhoria do desempenho motor, além de oferecer subsídio para uma opção de estimulação do movimento.
Abstract The aimed of this study was to verify the effect of a motor intervention program with exergames in children with risk and significant movement difficulty. 18 sessions of 45 minutes were performed.. The MABC-2 battery was used to identify children at risk and motor difficulty. In the pre-test, in the experimental group there were two children with difficulty of movement and four children with indicative of risk of difficulty, in the post-test analyzes, it was verified that only two children were at risk of difficulty and four were without difficulty of Movement. With this, it is suggested that the exergames can be useful tools for the improvement of the motor performance, besides offering subsidy for an alternative of stimulation of the movement.
Resumen El objetivo de este estudio fue comprobar el efecto de un programa de intervención motora con videojuegos activos en niños en riesgo e importante dificultad de movimiento. Se realizaron 18 sesiones de 45 minutos. Para identificar a los niños en riesgo y con motricidad difícil, se utilizó una batería MABC-2. En el análisis previo al estudio, en el grupo experimental había dos niños con dificultades de movimiento y cuatro niños sin dificultades de movimiento Con ello se sugiere que los videojuegos activos pueden ser herramientas útiles para logar una mejora del rendimiento motor, además de ofrecer ayuda a una alternativa de estimulación del movimiento.
