Relevance. Stress is how a person interprets and reacts to situations deemed too stressful or dangerous for them. Medical students’ academic achievement and physical and mental health are frequently negatively impacted by stressful environments in medical institutions. Cardiovascular fitness is the most important physical fitness factor associated with health, and physical fitness is a potent health indicator. The maximum quantity of oxygen that a person can transport to their working muscles during intense exertion is measured by their maximum oxygen uptake or VO2 max. When the connection between stress and physical activity has been studied, it has usually been from the standpoint of how exercise can improve mental health outcomes. Conclusion. Exercise and physical activity have been shown to positively impact mental health and the capacity to handle stressful situations. Additionally, it seems that exercise therapies enhance depression status.

Стрессовая реакция — это то, как человек интерпретирует и реагирует на ситуации, которые считаются слишком тревожными или опасными для него. Академическая успеваемость студентов-медиков, а также их физическое и психическое здоровье часто подвергаются негативному влиянию стрессовой среды в медицинских учреждениях. Сердечно-сосудистая подготовленность является наиболее важным фактором, связанным со здоровьем, а физическая подготовленность является мощным индикатором здоровья. Максимальное количество кислорода, которое может снабжать мышцы во время интенсивной нагрузки, измеряется его максимальным потреблением кислорода или VO2 max. Исследование связи между стрессом и физической активностью обычно основывается на изучении того, как упражнения могут улучшить результаты психического здоровья. Было показано, что упражнения и физическая активность положительно влияют на психическое здоровье и способность справляться со стрессовыми ситуациями. Кроме того, доказано, что лечебная физкультура способствует снижению депрессии.
