Experimental Procedure
The subjects were tested on two different occasions. In the first session, all cognitive tests were conducted, followed by a 30-minute walk on an electric treadmill (BH FitnessH - Explorer Pro Action). After a 5-minute warm-up, subjects trained for 25 minutes at 65%-75% of the maximum heart rate estimated for their age (220-age).29 The cognitive tests were conducted again at the 20th minute of the training, immediately after the completion of the training, and again
15 minutes later. One month after this first trial, the cognitive tests were conducted again using the same schedule without submitting the subjects to any physical exercise.
