Determining the influence of body composition on stress resistance, endothelial function and wellness and as a function of daily physical activity level and gender is of great medical-preventive importance․ The aim of this study was to analyse the influence of body composition on the stress resistance, endothelial function and wellness in different physical activity groups. A cross-sectional study was conducted with 2000 participants (829 men and 1171 women) aged 10-90 years. The Multiscan BS_OXI instrument was applied to measure the integral indicators․ For the study, statistical analysis was performed using Primer of Biostatistics version 4.03 by Stanton A. Glantz. Data analysis showed: (i) in the high physical activity group there was a significantly weak correlation between body composition and stress resistance in male (Rxy=0.24, p=0.000) and female (Rxy=0.28, p=0.0000) groups. In the case of low physical activity, a reliable weak correlation was registered only in the male group (ii) in the low physical activity group, there was a significant correlation between the body composition index and the change in the endothelium in the male (Rxy=0.4, p=0.000) and female group (Rxy=0.3, p=0.000) and in the group of participants with moderate physical activity, there was a significant correlation only in female group. (iii) In the high physical activity participant group, the correlation between body composition and wellness index was directly proportional in the male group (Rxy=0.33, p=0.000); in moderate and low physical activity, the correlation was directly proportional in the male and female groups. Thus, our study showed that the association of body composition with stress resistance, endothelial function and well-being depends on the level of physical activity and gender. However, further research is recommended to determine the influence of body composition ranges on various health indicators and to make recommendations and implement appropriate health and fitness programmes for the Armenian population, which should also focus on disease prevention.
确定身体成分对压力抵抗力、内皮功能和健康的影响，以及其与日常体力活动水平和性别的关系，具有重要的医学预防意义。本研究的目的是分析身体成分对不同体力活动组压力抵抗力、内皮功能和健康的影响。本研究采用横断面研究设计，共纳入 2000 名参与者（829 名男性和 1171 名女性），年龄 10-90 岁。应用 Multiscan BS_OXI 仪器测量整体指标。采用 Stanton A. Glantz 的 Primer of Biostatistics 版本 4.03 进行统计分析。数据分析显示：（i）在高体力活动组中，男性（Rxy=0.24，p=0.000）和女性（Rxy=0.28，p=0.0000）组中，身体成分与压力抵抗力之间呈显著弱相关。在低体力活动组中，仅在男性组中观察到可靠的弱相关（ii）在低体力活动组中，男性（Rxy=0.4，p=0.000）和女性组（Rxy=0.3，p=0.000）中，身体成分指数与内皮变化之间存在显著相关性，而在中体力活动组中，仅在女性组中存在显著相关性。（iii）在高体力活动组中，男性组中身体成分与健康指数之间的相关性呈正相关（Rxy=0.33，p=0.000）；在中、低体力活动组中，男女组的相关性均呈正相关。因此，我们的研究表明，身体成分与压力抵抗力、内皮功能和健康之间的关联取决于体力活动水平和性别。然而，建议进一步研究确定身体成分范围对各种健康指标的影响，并为亚美尼亚人口制定和实施适当的健康和健身计划，该计划还应侧重于疾病预防。
