Abstract

Objective: This study aims to empirically investigate the subtle physiological changes resulting from the complex interaction between exposure to blue light during late-night hours and high-intensity training programmes, specifically among young athletes, who represent the group most susceptible to both factors simultaneously. This interaction is considered one of the most pressing issues in modern sports medicine and applied physiology, given its far-reaching effects, ranging from hormonal disturbances and changes in the antioxidant system to impaired immune response and a decline in physical and cognitive performance. Method: The study adopted a two-group experimental design (control and experimental) on a purposive sample comprising young male athletes aged between 16 and 25 years, who regularly engaged in high-intensity training for at least three sessions per week at clubs in the province. The experimental programme was implemented over eight consecutive weeks and included pre- and post-test measurements of melatonin, cortisol, testosterone, and growth hormone levels, as well as indicators of oxidative stress, sleep quality (Pittsburgh Sleep Quality Index), and heart rate variability (HRV). Results: The study concluded that there were statistically significant differences at the 0.05 level between the two groups in all measured physiological variables, favouring the control group (which underwent blue light protection protocols). The study recommends the adoption of an integrated protocol system combining the management of blue light exposure, the optimisation of the recovery environment, and continuous physiological monitoring of young athletes. Novelty: This study empirically investigates the subtle physiological changes resulting from the complex interaction between exposure to blue light during late-night hours and high-intensity training programmes among young athletes, integrating hormonal responses, oxidative stress indicators, sleep quality, and heart rate variability within a single experimental framework.
