Motor Skill Learning

This study will compare two ways of learning juggling in university students during a regular practical course: (A) juggling based on throwing the balls in the air and (B) juggling based on bouncing the balls off the floor. The study will also examine whether the order in which students learn these methods (A then B vs. B then A) influences how their performance improves over time. Students will follow two 4-week practice periods separated by a 1-week break, and juggling performance will be assessed at three time points (baseline, after period 1, and after period 2). Performance will be scored from video recordings using anonymized study identifiers. Questionnaires about mood and flow experience will be collected at each assessment, and handgrip strength and brief computerized cognitive tasks will be assessed at baseline and the final evaluation in an exploratory manner. The main comparison of training methods will focus on results after the first period to reduce the influence of prior practice, while results after the second period will be used to describe learning trajectories, order effects, and transfer to different execution conditions.
