The Role of Motor Skills in the Sociometric Status and Perceived Social Status of Schoolchildren.

Introduction: Children with better motor skills tend to develop more positive peer relationships. However, there is little information about the relationship between motor skills and the five sociometric status groups, as well as how much it interferes with self-perception of social status.

Objective: To analyze the as sociation of low motor skills with sociometric status and perceived social status in students aged 7 to 10 years.

Evaluation isometric and isokinetic of trunk flexor and extensor muscles with isokinetic dynamometer: A systematic review.

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.

Effect of linear running velocity on the increase on foot pronation.

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 and increments of 1kmh 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.

How Does the Adjustment of Training Task Difficulty Level Influence Tactical Behavior in Soccer?

: This study aimed to investigate if player tactical skill level and age category influence team performance and player exploratory behavior in tasks with different difficulty levels. : In total, 48 youth male soccer players participated in the study (U15, = 24, mean age = 13.06 ± 1.

Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women.

Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women. The aim of the present study was to understand the effects of closed kinetic chain exercises with constant load on muscular strength, the knee torque conventional ratio (hamstring:quadriceps - H:Q), and functional capacity in the elderly. Nine untrained healthy elderly women participated in experimental resistance training.

Rebound boots change lower limb muscle activation and kinematics during different fitness exercises.

The purpose of this study was to evaluate electromyography and kinematic parameters of the lower limbs using rebound boots (RB) and barefoot during a gym workout. This information can be helpful to practitioners to schedule rehabilitation and training programs. Ten women (25 ± 9 years) volunteered for the study; inclusion criteria were as follows: subjects must have experienced the use of RB and the analyzed exercises for at least 6 months, and have no previous injuries in the lower limbs.

The Accuracy of Anthropometric Equations to Assess Body Fat in Adults with Down Syndrome.

Background: The aim of this study was to verify the accuracy of anthropometric equations to estimate the body density (BD) of adults with Down syndrome (DS), and propose new regression equations.

Materials And Methods: Twenty-one males (30.5 ± 9.
