Introduction. The need to preserve physical conditions during quarantine measures related to the SARS-CoV‑2 pandemic requires scientists and specialists to search for effective methods of physical education of students in self-isolation mode. Professionals suggest using functional training during the period of self-isolation, quarantine and other restrictions associated with the pandemic [1].
The aim of the study is to assess the impact of home functional online training on the level of physical fitness of students who are under restrictive measures related to the COVID‑19 epidemic.
Methodology and organization of the study. The total study period was about two months (April-May 2020). Participants: young men (average age – 19.46± 1.22 years) students of several large universities of the Krasnoyarsk Territory who voluntarily wished to participate in the study. All participants (n=238) complied with the requirements for self-isolation and restriction of freedom of movement (did not attend classes at universities and tried not to leave home). At the beginning of the studies, the participants were randomly divided into two equal groups (G‑1 and G‑2). All participants were offered a model of independent (home) functional training – performing special exercises (burpee), consisting of squats, flexion-extension of the arms and jumping up, performed at the fastest possible pace. Each workout consisted of a daily sequential execution of 10 cycles (each cycle included 10 repetitions) with a rest interval of 30 seconds between cycles. Participants (G‑1) performed independent training without online supervision by researchers. The participants (G‑2) performed the training online (with the camera turned on and an online broadcast available to other participants and researchers). To assess the level of physical fitness, fitness tests were used: bending the arms in the prone position and lifting the trunk in the supine position (the maximum number of repetitions in 1 min). The results were evaluated using the Student's unpaired t-test and the Pearson correlation coefficient.
The results of the study and their discussion. Statistical analysis showed the presence of significant (p<0.05) differences in the results of fitness tests. The average result in the arm flexion test was 32.16±12.43 times (G‑1) and 35.09±11.28 times (G‑2). The average result in the torso lifts test was 47.31±9.16 times (G‑1) and 49.52±11.35 times (G‑2). The results indicate a higher level of physical fitness of students who used home online workouts.
Conclusion. The use of home functional training in an online mode, which provides the possibility of objective control over the physical activity of young people, contributes to increasing the level of physical fitness of students who are under the negative impact of restrictive measures associated with the global coronavirus epidemic.
