Heart rate agreement between the 20-meter shuttle run test and virtual system in healthy children: a cross-sectional study.

Background: Earlier studies evaluated the physiological responses to video games in children with different clinical conditions; however, no study has compared active video games with an incremental field test in healthy children. The purpose of this study was to verify the agreement between the 20-m shuttle run test (20 m-SRT) and virtual system (VS).

Methods: This is a cross-sectional study of 235 children (9.

Performance and reproducibility on shuttle run test between obese and non-obese children: a cross-sectional study.

Background: Due to the increasing prevalence of obesity among children, Shuttle Run Test (SRT) has been used as primary outcome for assessment of both physical performance and responses to different physical training programs. Thus, this study aimed to compare the performance on SRT between obese and non-obese children and the reproducibility of two SRTs carried out on different days.

Methods: A cross-sectional study in which 40 children, aged from 8 to 10, were recruited from a public school.

Electrocardiographic changes by accidental hypothermia in an urban and a tropical region.

Background: Hypothermia is defined as a condition in which core temperature (rectal, esophageal, or tympanic) reaches values below 35 degrees C. This may be accidental, metabolic, or therapeutic. The accidental form is frequent in cold-climate countries and rare in those with tropical or subtropical climate.
