Prefrontal Hemodynamics and Working Memory After Exhaustive Aquatic Exercise
Sponsor: Manisa Celal Bayar University
Summary
This study compared prefrontal cortex hemodynamics and working memory performance following exhaustive aquatic exercise between endurance athletes and physically active individuals. Twenty-two healthy male participants aged 18-30 years, including 10 endurance athletes and 12 physically active controls, completed an incremental stepping exercise to exhaustion during head-out water immersion. The exercise was performed on a 20-cm step at xiphoid-level water depth, with cadence beginning at 18 steps/min and increasing by 2 steps/min every 30 seconds. Approximately 5 minutes after exercise, participants completed a seated 2-back working memory task while prefrontal cortex hemodynamic responses were assessed using functional near-infrared spectroscopy (fNIRS). Cognitive performance and prefrontal hemodynamic responses were compared between the two groups.

Incremental Exhaustive Aquatic Stepping Exercise
Participants performed stepping exercise on a 20-cm step during head-out water immersion at approximately xiphoid depth and approximately 30 °C water temperature. The protocol began at 18 steps/min, with cadence increasing by 2 steps/min every 30 seconds, and continued until exhaustion.
