BALANCE

We were unable to observe any changes either during or after the project. The setup in the classroom was somewhat problematic, with little to very little space. The children mostly did not perform the exercises correctly.

2

BALANCE

The 2c mostly enjoyed the circus times and were quite motivated because the children truly believed they were training for a circus performance. I also noticed here who listens well in class and tries to perform exercises correctly, and who just does what they please.

3

BALANCE

The children enjoyed it. The movement session in the morning at school was beneficial for them. It was a pity that the children often rushed through exercises and paid little attention to performing them correctly on their own. Showing the exercises once at the beginning was not enough; I frequently went to the children and demonstrated the exercises again.

3

BALANCE

Diverse exercise formats, very motivating, difficult to implement alone in this format.

2

CARDIO

The class was more inattentive and agitated during this period. The training was not conducive to the learning atmosphere.

3

CARDIO

Motivating and age-appropriate tasks, station rotation requires a lot of structure/clarity. The intervention varied in structure depending on the instructor.

3

CARDIO

The class became very agitated. It was difficult to calm them down afterwards. Great selection of exercises. Prefer fewer options but with clear structure.

3

CARDIO

The children enjoyed participating and had fun. On some days, it was good for them to move around, but at times they were also very agitated after the training. I would have liked to do balance or concentration training.

MENTAL

Perhaps next there could be a study or program focusing on LISTENING skills?!

3

MENTAL

The children enjoyed the exercises and were motivated.

3

MENTAL

The class found it difficult to engage in the exercises. It takes a lot of experience to do such tasks with children at our school. BiSSZO [game] was great!

3

MENTAL

The project was very well implemented by the instructors. Great tasks/exercises.
