Why the study?
Does continuous computer work for 15 min affect physiological functions in children aged 7 to 10 years?
Does continuous computer work for 15 min affect physiological functions in children aged 7 to 10 years?
Physiological resistance to computer work in primary school children increases with age, with sex-related differences emerging at ages 8 and 10.
May inform age-specific computer guidelines in schools; leaves open sex differences in developmental resilience to digital loads.
We studied the age- and sex-related functional characteristics of the central nervous system (CNS), cardiovascular system (CVS), lability of the visual sensory system, and mental capacity before and after a continuous computer work for 15 min in children aged 7, 8, 9, and 10 years. The results of the research showed that the resistance of the physiological systems of the body to loads associated with computer work increases in primary school children with age. We also observed sex-related differences: many parameters of functional performance during computer work at the age of 8 years were better in girls than in boys, which was due to a higher rate of development; at the age of 10 years, girls had a larger number of adverse changes in the functional state of the body compared with boys, which is possibly due to the onset of puberty.
