3.5. Evaluation of the Intervention
All participants agreed that 15 out of the 20 exercises were demonstrated understandably. Only four out of the 20 participants mentioned that one or two exercises were not explained understandably. These participants were contacted and got further instructions for these exercises. In summary, 98.4% of the 20 exercises were explained satisfactorily. The analysis of the question “Can you now perform the exercise xxx?” for the 23 juggling exercises showed that 68.4% agreed, 20.9% rather agreed, 7.2% rather disagreed, and 3.5% disagreed. The overall enjoyment of all sessions was rated with a mean value of 1.56 ± 0.16. The analyses of the question “Are you now in a positive mood?” led to a mean value of 1.38 ± 0.21. Most physical activity breaks were performed around noon (28.4%), before noon (22.7%), and in the afternoon (21.5%), while 14.9% of the sessions were performed in the evening, 6.5% at night, and 6.1% in the morning.The evaluation after finishing all physical activity breaks was completed by sixteen participants (women = 12, men = 4) of the intervention group (All participants agreed (93.8.%) or rather agreed (6.3%) that the physical activity breaks presented were diverse and lively. The mobilization and relaxation parts were enjoyed by all participants. When we asked them how challenging the juggling exercises were for them, seven participants (43.8%) found the exercises neither too challenging nor not challenging, five participants (31.3%) indicated that the juggling exercises were too challenging, and four participants (25.0%) were both challenged by some exercises and not challenged by other exercises. The balance tasks were neither too challenging nor not challenging for ten participants (62.5%). For two participants (12.5%), the balance tasks were challenging, not challenging, or too challenging as well as not too challenging, respectively. Most of the participants agreed that the physical activity break had a positive effect on their health (I agree: 11, 68.8%; I rather agree: 4, 25.0%; I rather disagree: 0, 0.0%; I disagree: 1, 6.3%) and their working routine (I agree: 11, 68.8%; I rather agree: 2, 12.5%; I rather disagree: 2, 12.5%; I disagree: 1, 6.3%). Ten (62.5%) participants confirmed that they increased their physical activity. Six participants reported being more physically active before, during, or after work, and two participants had started using the stairs instead of the elevator. The other two participants did not explain how they increased their physical activity. Everyone indicated a motivation to continue with the exercises. Fifteen (93.8%) wanted to continue the juggling, ten (62.5%), the mobilization exercises, six (37.5%), the balance tasks, and four (25.0%), the relaxation exercises.
