Cognitive Responses to Acute Breath-Hold Diving Training in Female Divers

Condition(s) studied

Investigational drug(s) / intervention(s)

Land-Based Breath-Hold Training: Participants will perform structured land-based breath-hold exercises consisting of repeated apnea efforts at 60% of individual maximal breath-hold capacity with standardized rest intervals.

Water-Based Breath-Hold Training: Participants will perform structured breath-hold exercises in a swimming pool environment consisting of repeated apnea efforts at 60% of individual maximal breath-hold capacity with standardized rest intervals.

Control Session: Participants will undergo baseline cognitive, respiratory, mood, and physiological assessments without structured apnea or breath-hold exercise intervention.

Study summary

This study aims to investigate the acute cognitive and physiological responses to breath-hold diving training in trained female divers. Participants will complete three separate sessions including a control session, a land-based breath-hold training session, and a water-based breath-hold training session in randomized order. Cognitive performance, mood state, heart rate responses, respiratory function, and maximal breath-hold capacity will be evaluated before and after the interventions. The study is expected to improve understanding of how acute apnea-based diving exercises influence cognitive functions and physiological adaptations under different environmental conditions.

Eligibility

Primary outcome measure(s)

• Working Memory Accuracy (2-Back Test) — Baseline and immediately after the intervention, within 5 minutes post-intervention.
  Accuracy score obtained from the computerized 2-back cognitive task.
• Reaction Time During the 2-Back Test — Baseline and immediately after the intervention, within 5 minutes post-intervention.
  Mean reaction time recorded during correct responses in the 2-back cognitive task.
