Study: NCT04084808

Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Cognitive flexibility
Description: Subjects will be required to undergo the Stroop task. They will have to answer as quickly as possible, with push buttons, to a colour stimulus, following specific rules, and get the highest possible number of right answers. The flexibility block will show a pre-signal on a screen in front of the subject (a square or a cross will be shown). The form presented will indicate if the subject must use the colour of the writing, or the word written. Each block will consist of 50 trials, 25% of which switching the condition of answer. During this test, reaction time in milliseconds (ms) as well as the number of right answers will be measured.~This test will be measured before the exercise protocol, during the 3-minutes exercise bouts, and every 15 minutes during the 45 minutes following exercise.

Intervention: Brain oxygenation
Description: Optic imagery (Near-infrared spectroscopy, or NIRS) is a non-invasive technique allowing a fine investigation of the inner workings of the brain. It allows discrimination of oxygenated hemoglobin from deoxygenated hemoglobin, which informs on the coupling between blood flow and oxygen consumption inside the brain. To measure brain oxygenation with NIRS, optodes will be installed on the subject's skin without glue or transmission gel.~\[ Time Frame: During Stroop's task (i.e.before the exercise protocol, during the 3-minutes exercise bouts, and every 15 minutes during the 45 minutes following exercise). \] Measured with near-infrared spectroscopy (NIRS).
