Key result
Measurement of muscle oxygenation by NIRS during exercise in children showed good reproducibility when deoxy-hemoglobin data were averaged every 5, 10, 20, and 30 seconds.
Why the study?
Is measurement of muscle deoxygenation by NIRS reproducible in healthy children during exercise?
Observational (n=12)
Is measurement of muscle deoxygenation by NIRS reproducible in healthy children during exercise?
NIRS provides reproducible measurements of muscle deoxygenation in children during exercise when data are averaged over 5 to 30 seconds.
May enable consistent NIRS use in pediatric exercise research; leaves open validation in clinical populations.
This study was designed to test the reproducibility of muscle oxygenation by NIRS in children during exercise. Twelve healthy non-obese and non-trained children performed one maximal graded test, and four 6-min constant load cycle exercises. Deoxy-hemoglobin (Hb/Mb- H+) data were averaged every 1, 5, 10, 20 and 30s. Hb/Mb- H+ data averaged every 5, 10, 20 and 30s showed good reproducibility. When averaged every second, Hb/Mb-H+ values were reproducible after the first minute of exercise. Based on 1s averaged signal modeling, time period and t values for Hb/Mb-H+ were not reproducible but mean response time values showed an acceptable reproducibility.

Leclair et al. (2010) conducted an observational in Healthy children (n=12). Measurement of muscle oxygenation by NIRS during exercise was evaluated on Reproducibility of muscle oxygenation (Hb/Mb-H+) data. Measurement of muscle oxygenation by NIRS during exercise in children showed good reproducibility when deoxy-hemoglobin data were averaged every 5, 10, 20, and 30 seconds.
