Figure 3.

Coefficients of attenuation. The figure shows the mean ± s.e.m. values of the three coefficients of attenuation as computed for the young (black bars) and the elderly (grey bars) groups at comfortable (filled bars) and fast (rayed bars) speed. Results of the ANOVA have also been reported: * = age effect; ° = condition effect; ^ = interaction effect; p < 0.05.
