(Figure 1f), the participant was asked to simulate downhill
skiing.
The duration of each exercise varied from 1 to 2 min. The
score was calculated based on the accumulated time that the
COP indicator was over the targets or/and based on
the number of successful trials. The exercises were presented
in random order. Once a consistent score in each exercise
was attained by the participants, the difficulty level of the
exercise was increased. The initial difficulty of the exercises
was adjusted to each participant based on their performance
during the familiarization session. During each training
session, an equal number of rounds of each exercise was
presented to the participant.
