Overview

Case study demonstrates autonomic nervous system shifts in divers, highlighting stress recovery dynamics.

Key Points

  • Heart rate variability analysis revealed significant autonomic shifts during and after a closed-circuit rebreather dive.
  • HRV indices showed decreased RMSSD and SDNN during the dive, indicating reduced parasympathetic activity.
  • RR interval monitoring was conducted using the MCM100 device, with data processed through Kubios software.
  • Findings emphasize HRV profiling as a valuable noninvasive method for monitoring stress in professional divers.
