5. Conclusions

To conclude, the 12-week physical activity break with coordinative exercises led to improvements in the juggling performance and subjective health and working routines, without any changes in general motor abilities like reaction time, finger and hand dexterity, or dynamic balance. In addition, the web- and video-based physical activity breaks had good feasibility and were rated as enjoyable by the participants. Therefore, this pilot study shows that it is possible to implement physical activity breaks at the workplace. The implementation helps to reach a large group of the population (16 to 65 years). Furthermore, it offers an opportunity to be physically active within the working hours. These aspects are important from a public health perspective. For further research, we recommend the implementation of physical activity breaks with a sedentary sample and/or a higher training volume (e.g., 15 to 20 min 3 to 5 times per week).
