It would have been interesting to know more about
subjects’ motivations for taking part in the study.
Table 1 shows that, at study entry, many of the
participants were slightly concerned about their
cognitive performance. These concerns might have
motivated participants in the experimental group to
change their practice of PA. Since loss of cognitive
functions is a frequent concern for the elderly [105,
106], there is a strong argument for including the
maintenance of cognitive vitality in future campaigns
to promote PA in this population.
