The influence of ball-juggling on emotional states, blood pressure and sleep-quality among medical students during end-of-year exam preparation.

Juggling-exposure therapy has been employed in the management of anxiety and post-traumatic stress disorder. However, there is little evidence of the effectiveness of juggling-exposure in improving emotional states in subclinical conditions. This study aimed at evaluating the effect of a course of juggling on emotional states, sleep quality and blood pressure among medical students at a critical stage of their academic training. Blood pressure, psychometric and quality of sleep assessments were performed pre- and post-examination period for two groups of students: juggling-exposed (n = 9) and non-juggling-exposed (n = 11). Juggling exposure consisted of practice-drills for one hour per week during the period spanning the student's scheduled exams. Comparisons were made between quantitative measures that were collected pre- and post-the course of juggling drills. Differences in scores and measures were expressed as percentage-change and compared between non-juggling and juggling groups. Overall, there was a decrease in depression and anxiety scores between the pre-to post-exam periods. This decrease was statistically significant for both non-juggling and juggling groups with respect to anxiety, but only the juggling-exposed group had a significant reduction regarding depression scores. However, when calculated as percentage-change over the pre-to post-exam period, there was no significant difference in any of the parameters for either of the two groups. Practicing juggling drills had an influence on emotional states.
