NIRS Forearm Morphology and Optode Placement Data for Rock Climbers

A methodological study on near-infrared spectroscopy (NIRS) assessments in rock climbers, comprising data from 28 participants for forearm morphology and 22 participants for optode placement effects. The dataset includes measurements of adipose tissue thickness, flexor digitorum superficialis thickness, and flexor digitorum profundus thickness at three forearm sites, as well as haemodynamic outcomes from vascular occlusion and incremental finger flexor endurance tests. It was authored by Simon Vandenhaute and last updated on June 3, 2026.

Use Cases

• Analyze the relationship between forearm morphology and NIRS signal penetration depth based on ultrasound measurements.
• Compare haemodynamic outcomes like half-time recovery of reoxygenation (StO₂ HTR) between different NIRS optode orientations.
• Investigate the effect of optode placement on muscle reoxygenation between contractions during incremental endurance tests.
• Validate NIRS measurement protocols for the flexor digitorum profundus muscle in climbing research.

Strengths

• Includes data from 28 participants for anatomical measurements and 22 participants for physiological tests.
• Reports specific findings, such as the FDS–FDP border located at 17.6 ± 4.0 mm depth.
• Provides statistically significant results, including a 2.7 ± 2.9% lower ΔStO2 relief—last with perpendicular optode orientation.

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 small in scale at 96.0 KB, indicating limited scope.
