A 2014 quasi-experimental (controlled) study with cross-over design with 31 individuals. Results suggest: “Both control rest and the intervention gave significant increase of SDNN, but while the increase was +15% (P < 0.05) in the control period, it was +32% (P < 0.05) in the test period. TP value did not increase significantly in the control period (+19%; P > 0.05), but showed high significance in the test intervention period (+126%; P < 0.01)…. A highly significant decrease in heart rate (P < 0.01) was observed after the CST as compared to that after the rest period.”
