In the last few years, the approach to evaluating the physical fitness (hereafter PF) in children and youth has been changing. Due to this change, there has also come a need of change in test batteries. In one section of the partial research project of Physical Education Dept. of PdF MU, which forms part of the research project School and Health for 21 Century, we deal with the monitoring of health-related fitness in primary school children by means of test batteries.
