目的：压力是由多种因素引起的一种状态，其特征是身体机能失衡、神经系统受损和紧张。本研究的目的是检查皮质醇水平（健康年轻人因压力而增加）对动态和静态平衡分数的影响，并展示高压力造成的结果。 方法：在本研究中，107 名年龄在 19 至 23 岁之间的健康医学系二年级学生（将参加相同的委员会考试）纳入研究。第一次天平测量和唾液样本是在委员会考试前40天进行的，这一时期被认为是放松期。在委员会考试当天，同样的学生再次被考虑进行平衡测量；收集唾液样本并测定皮质醇浓度。这一时期被认为是压力时期。状态特质焦虑量表（STAI）是在参与者放松和有压力的时期进行的。动态平衡分数通过星偏移平衡测试（SEBT）进行测量。静态平衡得分通过单腿站立平衡测试 (OLSBT) 进行测量。结果：与放松时期相比，压力时期的平均皮质醇水平增加了约 9 倍。表明状态焦虑的 STAI 的增加支持了这种增加。在压力时期，动态平衡得分在各个方向上均呈现明显下降。此外，在有压力的时期，与放松时期相比，静态平衡得分明显下降。结论：这项研究表明，压力会对动态和静态平衡产生负面影响，即使是很短的时间。我们相信，当与长期压力和平衡测量相关时，我们的研究将形成积极的来源和基础。
OBJECTIVE: Stress is a condition caused by various factors and characterized by imbalance in body functioning, impair in nervous system, and tension. The purpose of this study was to examine the effects of cortisol level, which increases in healthy young individuals due to stress, on dynamic and static balance scores as well as to present the results caused by high levels of stress.METHODS: In this study, 107 healthy medicine faculty students in their second year (who will take the same committee exam) aged between 19 and 23 years were included. The first balance measurements and saliva samples were taken 40 days before the committee exam, and this period was acknowledged as the relaxed period. The same students were considered for balance measurements again on the day of committee exam; saliva samples were collected, and cortisol concentration was determined. This period was acknowledged as the stressful period. The State-Trait Anxiety Inventory (STAI) was given to the participants in their relaxed and stressful periods. Dynamic balance scores were measured with Star Excursion Balance Test (SEBT). Static balance scores were measured with One Leg Standing Balance Test (OLSBT).RESULTS: The mean cortisol level was found to increase approximately 9 times in stressful periods compared with that in relaxed periods. STAI, which shows state anxiety, showed an increase supporting this increase. In stressful periods, dynamic balance scores showed obvious decrease in all directions. In addition, in stressful periods, an obvious decrease was observed in static balance scores compared with those in relaxed periods.CONCLUSION: This study showed that stress negatively affected dynamic and static balance, even for short periods of time. We believe that our study will form a positive source and basis when correlated with long terms stress and balance measurements.
