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

27. maj 2026 opdateret af: Görkem Açar, Istanbul Gelisim University

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

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Control Session
Participants will complete baseline cognitive, respiratory, mood, and maximal breath-hold assessments without structured breath-hold exercise.
Andet: Control Session
Participants will undergo baseline cognitive, respiratory, mood, and physiological assessments without structured apnea or breath-hold exercise intervention.
Eksperimentel: Land-Based Breath-Hold Training
Participants will perform land-based breath-hold exercises at 60% of individual maximal breath-hold capacity followed by post-intervention cognitive and mood assessments.
Adfærdsmæssigt: 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.
Eksperimentel: Water-Based Breath-Hold Training
Participants will perform water-based breath-hold exercises in a swimming pool at 60% of individual maximal breath-hold capacity followed by post-intervention cognitive and mood assessments.
Adfærdsmæssigt: 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.
