Physical activity can improve health as well as reduce stress and the risk of developing several widespread diseases. However, there exists no accepted standard biomedical examination-method for stress evaluation. The purpose of this study was to investigate the effect of regular physical activity on stress and wellness as well as the evaluation of potential biomarkers in this field. This study included 105 people (mean age = 36.57 ± 1.4 years) who were randomly assigned into the exercise group 1 (EG-1) (n = 41), the exercise group 2 (EG-2) (n = 30), and the control group (CG) (n = 34). Measurements of stress and wellness were obtained by Multiscan BC-OXI before and after experimental period. This device presents a multifrequency segmental body composition 3D analyser with digital pulse oximeter. The key indicators of stress as well as for wellness were significantly improved in the EG-1. Parasympathetic activity showed significant changes as potential stress biomarker. Statistically significant gender differences were not observed in the comparable groups. The results suggest that the stress resistance and well-being significantly improved in the EG-1 due to regular physical activity. However, further research is necessary to determine effects of physical activity on integral health indicators.

体育锻炼可以改善健康，减少压力和患多种广泛疾病的风险。然而，目前还没有公认的标准生物医学检查方法用于压力评估。本研究的目的是调查定期体育活动对压力和健康的影响，以及评估该领域潜在的生物标志物。这项研究包括 105 人（平均年龄 = 36.57 ± 1.4 岁），他们被随机分配到运动组 1 (EG-1) (n = 41)、运动组 2 (EG-2) (n = 30) 和对照组 (CG) (n = 34)。通过 Multiscan BC-OXI 在实验期前后获得压力和健康的测量值。该设备提供了一种带有数字脉搏血氧仪的多频分段身体成分 3D 分析仪。在 EG-1 中，压力和健康的关键指标得到了显着改善。副交感神经活动作为潜在的压力生物标志物显示出显着变化。在可比组中未观察到统计学上显着的性别差异。结果表明，由于规律的体育锻炼，EG-1 的抗压性和幸福感显着提高。然而，需要进一步的研究来确定身体活动对整体健康指标的影响。
