2.3.4. Evaluation of the Intervention
After each training session, the participants had to answer a short questionnaire (maximum of 6 questions), designed to gain insight into whether the participants were able to accomplish the planned training progression or if there was a need to change the training content. We asked the questions “Was the exercise xxx explained/demonstrated understandable for you?” (yes/no) and “Can you now perform the exercise xxx?” (1- “I agree” to 5- “I disagree”). Furthermore, we asked how they enjoyed the session overall (1- “I enjoyed it very much” to 5- “I did not enjoy the training”), if they were in a positive mood after the training (1- “I agree” to 5- “I disagree”), and when (time) the activity break was performed. At the end of each month, the participants had one session in which all new learned exercises of that month were performed again. After this session, we asked them if they were able to perform those exercises (1- “I agree” to 5- “I disagree”). Overall, 23 juggling exercises were learned by the participants. Besides this evaluation of each session, the participants were asked to answer an evaluation of the intervention after finishing all the physical activity breaks. With this evaluation, we examined how they enjoyed the intervention overall (1-“I enjoyed it very much” to 5- “I did not enjoy”), how they enjoyed the different parts of one session (e.g., “Do you agree, that the relaxation exercises were comfortable and relaxing for you?”) and if the active breaks presented were diversified and lively (1- “I agree” to 4- “I disagree”). In addition, we wanted to know if they planned to continue practicing the exercises following the study participation (yes/no). Furthermore, they were asked if they think that the performance of the active breaks had a positive effect on their working routine and health (1- “I agree” to 4- “I disagree”). Finally, we wanted to know if they noticed an increase in their physical activity behaviour (yes/no) and, if yes, how they observed this change in their behaviour.
