Cardiorespiratory and Muscle Blood Flow Data from Breath-Holding Exercise Study

14 young adult participants performed maximal breath-holding during knee extension exercise under hypocapnic and normocapnic conditions. The dataset contains raw measurements for apnea duration, end-tidal gas tensions, peripheral oxygen saturation, active muscle blood flow, cardiovascular responses, and cerebral artery blood velocity, supporting a related manuscript. It was authored by Matsutake and last updated on April 20, 2026.

Use Cases

• Analyzing the relationship between arterial CO2 partial pressure and active muscle hypoperfusion based on blood flow and vascular conductance data.
• Modeling time-dependent cardiovascular responses to apnea during exercise based on heart rate and blood pressure measurements.
• Investigating gender representation in physiological studies based on the noted participant composition (1 female out of 14).

Strengths

• Includes raw data for 14 participants across multiple physiological measurements.
• Data is structured across 7 Excel sheets corresponding to specific figures and tables from the related study.
• Clear participant counts are provided for each measurement subset (e.g., n=9 for cerebral measurements).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 38.6 KB, indicating limited scope.
