Given the steady decline in physical activity among schoolchildren and due to quarantine restrictions caused by the Covid-19 pandemic, there is a threatening trend of declining levels of their physical health. Lately, the world has undergone significant changes, namely the emergence of the Covid-19 virus, which marked all human lives. Under the conditions of the Covid-19 pandemic, physical fitness is essential for preventing physical and mental health problems among schoolchildren. This requires scholars to develop preventive measures aimed at increasing the body's resistance to disease. Materials and methods of research. The study was conducted in Chernivtsi specialized school with physical and mathematical profile № 6. The experiment involved 36 boys who attended a club in orienteering. They belong to the main medical group. They have been introduced to the specially designed 234-hour orienteering-based program which included theoretical and practical classes, most of which were conducted outdoors in a variety of landforms. We used active and interactive forms of training, technical means, information and communication technologies of training, which contained topographic computer programs, orienteering simulators (computer games “Catching Features”, “Virtual-O”). Results. The results of the study indicate positive changes demonstrated by the 11-year-old boys under the influence of orienteering. At the end of the pedagogical experiment, we observed a statistically significant difference (p<0.05; p<0.01) in the dynamics of the right-hand dynamometer, resting heart rate, lung vital capacity, and Rufier index. The indicators of cognitive functions, in particular, the amount of short-term memory had significantly (p <0.01) improved among 11-year-old boys by 83.2 % (p<0.01), and the rate of information processing improved by 101.1 bits (p<0, 01). Moreover, the indicator which characterizes the coordination abilities of boys underwent the greatest changes. The average result for orienteers improved by 6.9 s, which was 90.7 % (p<0.01). The most positive changes were observed in motor tests, which characterize dexterity, strength, endurance and speed power qualities. A statistically significant difference was observed among children when they were performing the tests, such as shuttle runs 4x9 m (p<0.05); long jump (p<0.05); running without taking into account the timing (p <0,01); flexion, an extension of the arms in the supine position (p<0,01), as well as special physical training in overcoming the distance in orienteering at 8 checkpoints. Conclusions. The obtained results testify to the effectiveness of the proposed program based on the innovative forms of orienteering applied to the group of 11-year-old boys. Thus, the proposed program should be included in the organisational and methodological support of health and recreational activities in out-of-school educational institutions of tourism and local lore during the Covid-19 pandemic.
