Brief summary: The purpose of the study is to verify the effect of juggling exercises on selected cognitive functions (reaction time, attention) and postural stability variabilities (based on center of pressure signal) in two different protocols: \[1\] a randomised crossover study design, \[2\] a randomised repeated measurement design.

Detailed description: Juggling is a form of exercise, that can engage humans, both cognitively and physically. One of the positive aspects of taking up this form of exercise is the growing evidence indicating that juggling improves the well-being of exercisers. Most importantly, the juggling intervention causes an increase in the volume of the gray matter and white matter in the human brain, and thus shows potential for neuroplasticity. In addition, unhealthy aging is observed nowadays, which causes both physical and cognitive decline in daily functioning, further interfering with the elderly's ability to perform daily activities. Therefore, the addition of juggling exercises may have a positive effect on the changes that occur with aging.

However, currently there are hardly any data on the juggling effect on cognitive functions and on postural stability. Therefore, the study aims to examine the effect of juggling exercises on selected cognitive functions and postural stability variables in two different randomised trials.
