Effect of Physical Exercise on Motor Learning Acquired With Physical or Mental Practice

Participants in the sleep deprivation group will spend a night awake, under the supervision of an investigator, at Croix-Rousse Hospital. The investigator will provide a list of activities to maintain the participant awake.

Participants in the normal night group will spend one night sleeping in their own home.

"Participants in the physical exercise group (i.e. IM+HIIE, PP+HIIE, SD+PP+HIIE) will start with a 2-minute warm-up on an ergometer cycle.~After the warm-up, they will perform 3 minutes of exercise at a workload customized to their maximal aerobic power (MAP) corresponding to 80 % their MAP and then rest actively for 2 minutes at 40 % of MAP. This cycle of 5 minutes will be repeated 3 times in row, resulting in a total of 17 minutes of physical exercise including the warm-up."

Participants will watch a documentary during an equivalent time as the physical exercise (i.e. 17 minutes).

On the bimanual finger tapping task composed of 8 elements, the participant will be required to repeat the motor sequence mentally using MI (mental rehearsal of movement) during twelve blocks of 30 seconds. Participant will imagine performing the sequence as fast and accurately as possible without overt movement.

Participants will practice a bimanual sequential finger tapping task composed of 8 movements. Participant will be required to perform the sequence as fast and as accurately as possible during blocs of 30 s (i.e. twelve blocs during training).
