“…It should be noted that there is virtually no data on the functional reserve of the heart, according to the Rufier index, at specific ages and taking into account the sex of students. In this aspect, attention is drawn to studies and recommendations for differentiated assessment of the Rufier index according to the age of students [12][13][14]29]. And the gender differences obtained by us and other authors [8,19,21] of the Rufier index actualize the issue of differentiated assessment of the Rufier index according to the sex of schoolchildren.…”

Relevance. The most common indicators for assessing the effectiveness of health technologies are the cardiovascular performance of adolescents. At present, there is insufficient information on the quantitative substantiation of informativeness, prognostic and diagnostic significance of such indicators in the process of correction of functional and reserve capabilities of the cardiovascular system of adolescents. Purpose: To determine the levels of functional reserve of the heart according to the Rufier index and to study the physical performance of students aged 12-14 years of different medical groups. Materials and methods. 178 seventh-eighth-graders aged 12-14 (85 boys and 93 girls) were examined. All students voluntarily participated in this experiment, and the written consent of their parents was obtained. Physical performance was studied according to the parameters of the bicycle ergometric test PWC170. The division of students into medical groups was carried out according to the indicators of the level of functional and reserve capabilities of the cardiovascular system, conducted according to the Rufier index. Statistical analysis of the results was performed using the application package Statistica-V.10.0. The normality of the distribution was checked by the Kolmogorov-Smirnov test. The studied indicators are described by the median (Me) and 25, 75 percentiles. The relationships of the studied indicators were analyzed according to Spearman's rank correlation coefficients. To determine the reliability of differences in indicators used the criterion of Kraskel Wallis. Results. The main group included 13.5% of adolescents, the preparatory group – 35.4%, the special medical group – 51.1% of students. Among student-athletes, 25.9% of boys and 45.4% of girls belong to a special medical group. In school athletes, the correlations between the Rufier index and the PWC170 test are low and statistically insignificant. Indicators of physical performance in the range of 25-75 percentiles do not differ in different medical groups. This indicates that in a special medical group there are students with medium and high levels of physical fitness. Conclusions. The established age and gender differences in the functional reserve of the heart of schoolchildren determine the need to develop differentiated approaches to the assessment of the Rufier index. Physical performance in different medical groups varies in a fairly wide range. The division of students into medical groups according to the Rufier index does not reflect the level of physical performance of students and, accordingly, their real adaptive capabilities. Further studies are needed on the informativeness of using the Rufier test to divide students into medical groups.

“…Moreover, urine sampling was performed to assess oxidative stress using parameters like free radical concentration, specifically Reactive Oxygen Species (ROS) and Glutathione Disulfide (GSSG). This assessment offered insights into the temporal dynamics of oxidative stress in response to physical activities of different durations post exertion [30]. Urine sample collection was carried out in the morning before breakfast, referred to as baseline (T0); before putting on the equipment and performing the rope exercise, referred to as pretest (T1); and 90 min and 3 and 5 h after the end of the rope exercise, referred to as T2, T3 and T4, respectively.…”

Canyoning activities require physical effort, highlighting the importance of maintaining a proper physical fitness. Canyoning guides emerge as key figures, not only to ensure safety during the experience but also to handle unforeseen situations promptly. This study aims to assess the physiological profile of canyoning guides and the cardiorespiratory demands experienced during rope activities by means of oxygen uptake and heart rate measurements. Seventeen canyoning guides (42.6 y ± 10.78; BMI of 24.0 kg/m2 ± 2.95) carried out coordinative and conditional tests. The participants showed good values in strength tests (27.3 cm ± 5.97 and 23.3 rep ± 8.06 in SJ and PUp tests, respectively), while the flexibility of males and females was below and well above the average, respectively. A noteworthy result was observed in the reaction test, in which a better performance was recorded with the non-dominant hand (168.1 ms vs. 202.0 ms). All subjects exhibited a low aerobic capacity by means of an RD test (10.6 ua ± 6.62). During rope activities and emergency/support simulations, metabolic and cardiovascular data indicated that a moderate/high effort was exerted, confirmed by an oxidative stress analysis. In conclusion, this study demonstrated how canyoning guides face significant physical requirements, but their physiological profile regarding aerobic power was not appropriate. Therefore, these findings could offer valuable insights into the development of specific training to ensure an appropriate aerobic fitness to perform canyoning safely.

“…The idea of our work is to take into account both the upper and lower indicators together by improving the Moshkov rhombus model and thus increase the validity of the asymmetry indicator in the frontal plane of the body relative to the scoliosis predictor indicator in first graders. It is clear that ensuring a sufficient level of validity of health tests is a serious problem in the theory and practice of physical activity of primary school students Zanevskyy et al, 2017).…”

Purpose: the purpose of the study was to increase the validity of the indicator of asymmetry in the frontal plane of the body in relation to the prevention of scoliosis in first graders. Material & Methods: thirty-four students aged six to seven years – 18 boys (with body length and weight M±SD=118,9±2.1 cm; 21,6±1,1 kg) and 16 girls (118,2±1,8 cm, 21,2±0,9 kg) were randomly divided into the main group and the comparison group. In addition to standard physical education lessons, students of the main group completed a program of physical rehabilitation in order to prevent the development of posture asymmetry. At the beginning (September) and the end of the academic year (May), the students were measuring the curvature of the spine in the frontal plane according to the Moshkov test and bending to the sides. Results: in addition to the well-known model of the Moshkov rhombus, the asymmetry of the students’ bodies was determined using an improved indicator equal to half the sum of the absolute values of the differences in the lengths of the upper and lower sides of the Moshkov rhombus. There was no statistically significant difference between the boys, both according to the results of the Moshkov test (δ=0,3%; p=0,512), and according to the results of bending to the sides (δ=1,4%; р=0,379). At the beginning of the academic year, the value of the asymmetry indicator in the main group was practically equal to the corresponding value in the comparison group (δ=2,2%; р=0,815). At the end of the academic year, the value of the indicator in the main group was significantly less than its value in the comparison group. (δ=32,8%; р=0,031). Conclusions: the indicator of asymmetry in the frontal plane of the body proposed in this work, due to taking into account the magnitude of the curvature of both the upper and lower parts of the spine, made it possible to obtain a significantly higher validity (p=0,02) compared to the well-known indicator of the Moshkov rhombus, which in one parts of the spine – upper or lower (р=0,05).
