Thirty-eight pairs of monozygotic twins were assessed for anthropometric measurements to estimate body fat. Physical fitness was estimated with treadmill test and use of ergospirometer. Daily physical activity was estimated from the daily count of steps measured by a pedometer during 3 days. Fasting blood samples were used to determine blood glucose, insulin, lipid parameters. The Homa-IR and HOMA- &be...

Use of physical activity and cardiorespiratory fitness in identifying cardiovascular risk factors in male Brazilian adolescents
Abstract The aim of this study was to investigate the impact of physical activity (PA) and cardiorespiratory fitness (CRF) levels on the prevalence of overweight and high blood pressure levels in adolescents. In this observational, cross-sectional study, 614 boys aged 10-14 years were assessed for height, body mass, body mass index (BMI), waist circumference (WC) and blood pressure (BP). CRF was assessed using a run test (L éger Test) and subjects were then grouped according to their CRF level. PA level was assessed through a questionnaire (The Three Day Physical Activity Recall) and classified into two groups, name...

Time-motion analysis and effort-pause relationship in taekwondo combats: a comparison of competitive levels
Abstract To improve the combat sports training processes, the knowledge of effort:pause (E:P) ratio and of the high intensity:low intensity (HI:LI) relationship may be useful. However, no studies have investigated these aspects in taekwondo (TKD) official matches from different levels. The aim of this study was to analyze and compare the temporal structure of TKD combat matches at regional and state-level events. Thirty-four combat matches involving male TKD black belt athletes were analyzed. The athletes took part in two separate championships according to their level of competitiveness. Non-parametric distributions were ...

Visual behavior and the quality of decision-making on volleyball
This study aims to verify the visual behavior using the analysis of both quantity and duration of visual fixation and the quality of the DM in volleyball players and athletes from other sports in extreming attacking (EA), cental attack (CA), setting (SE) and blocking (BL) situations. The visual behavior was analyzed during the evaluation of volleyball scenes with an eye-tracking system. The first decision the volunteer voiced was determined as his solution for the scene presented and it was used for analyzing the DM quality. For the quantity of visual fixations, the independent t-test was used to compare groups in the foll...
