Given
the variability in cognitive development
in people with DS, some of the
participants who did not learn to
ride may have simply needed more days of practice and training. This
conclusion is supported by the general
observation that several riders in
the EXP group were close to meeting
the criterion of 9 m on the final day
of the intervention but did not
achieve it. In the future, this hypothesis
could be tested by providing
access to training bicycles for a longer
period than the standard 5 days
