Heart Rate Dynamics Across Dive Phases for 20 Professional SCUBA Divers

Twenty certified divers performed standard dives to a minimum depth of 66 feet as part of a real-world study. The dataset, authored by Subhojit Jash and last updated in April 2026, likely contains heart rate measurements across six dive phases: rest, pre-dive, descent, bottom, ascent, and post-dive.

Use Cases

• Analyzing differences in heart rate dynamics between dive phases based on the described six-phase protocol
• Comparing cardiovascular reflex indices, such as percentage heart rate drop, between novice and experienced divers
• Investigating the persistence of bradycardia at constant depth based on the study's findings
• Modeling the influence of diving experience on autonomic nervous system responses in a real-world setting

Strengths

• Data is derived from a real-world study involving 20 certified professional divers
• The protocol specifies a controlled dive to a minimum depth of 66 feet with a 5-minute bottom phase
• Results highlight a specific 7.71 percentage point difference in heart rate drop between experience groups

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small at 24.3 KB, indicating limited scope
