Robust mediation analysis (Zu and Yuan, 2010) revealed that balancing-induced changes in oxygenated hemoglobin (slope coefficient) in the dorsolateral part of the SFG conveys the effect of age on wobble board performance. A Huber-type weight was applied to control 5% of cases (κ = 0.05), as originally proposed by Zu and Yuan (2010). Note that the influence of sex and Baecke’s sport score was partialed out in the analysis.
