The impact of physical exercise with additional visual tasks on UDVA and accommodation sensitivity in children: the mediating role of kinetic visual acuity.

Purpose: This study investigates the impact of physical exercise supplemented with visual tasks on children's uncorrected distance visual acuity (UDVA), kinetic visual acuity (KVA), and accommodative sensitivity, with an analysis of the mediating role of KVA.

Methods: A total of 168 third-grade students from four natural classes in a primary school in Suzhou City were randomly assigned to either an experimental group ( = 86) or a control group ( = 82). The experimental group engaged in 30 cycles of ciliary muscle training tasks with visual targets presented for 3 s during physical exercises, while the control group participated in regular physical exercises.

The impact of additional visual tasks in physical exercise on balance ability among 9-10-year-old children: the mediating effect of visual acuity.

Purpose: This study aimed to explore the effects of additional visual tasks in physical exercise on the vision and balance ability of children, and to verify whether children's vision mediated the influence of physical exercise on their balance ability.

Methods: The study randomly selected 86 students aged 9-10 years old from a school in Suzhou city, dividing them into an experimental group ( = 43) and a control group ( = 43). The experimental group participated in physical exercise with additional visual tasks, while the control group engaged in routine physical exercise.
