The impact of diurnal sleep on the consolidation of a complex gross motor adaptation task.
Bottom Line: A significant decrease of accuracy during straight-line riding after nap and wakefulness was shown.We found that the duration of rapid eye movement sleep as well as sleep spindle activity are negatively related with gross motor performance changes over sleep.Together these findings suggest that the consolidation of adaptation to a new steering device does not benefit from a 2 h midday nap.

Mentions: We found a significant negative correlation between time spent in REM sleep during experimental nap and the oversleep change in straight-line riding (r10 = 0.855, P = 0.002; cf. Fig. 4a). The more time subjects spent in REM the worse was straight-line riding after nap. Furthermore, sleep SpA during experimental nap was strongly negative related to the oversleep change in slalom riding (r10 = 0.789, P = 0.007; cf. Fig. 4b). Subjects with high sleep SpA during nap after gross motor learning showed higher SDSA, indicating a more unstable handling of the bicycle.
