The Effect of Cortisol Hormone on Theoretical Exam Performance among Students of Physical Education and Sports Sciences: A Physiological-Psychological Study

Abstract

This study investigates the relationship between cortisol hormone levels and academic performance during theoretical examinations among students of Physical Education and Sports Sciences. Stress during exams triggers a physiological response involving increased cortisol secretion, which may impair cognitive functions such as memory, concentration, and decision-making. Using salivary cortisol measurements, perceived stress questionnaires, and official academic scores, the study found a significant negative correlation between cortisol levels and students’ exam performance. It also identified perceived stress as a contributing factor. The results highlight the need for integrated psychological and physiological stress management interventions to enhance students’ academic outcomes and overall well-being.
