One of two physicians (A.M., K.T). was present during training sessions.
Study staff was present at training sessions to ensure adherence to the study protocol.
Five trained swimming coaches were present during all training sessions in order to give technical advice and control the intensity and duration of the training and to secure a safe training environment.
A trained and certified fitness professional was present at all training sessions for safety and to ensure protocol adherence.
A trained and certified exercise professional was present at all training sessions to ensure safety and protocol adherence.
One of the two main investigators is present at all training sessions in the skills laboratory at Rigshospitalet, University Hospital of Copenhagen where the simulator is located.
Two sessions were conducted daily: one in which prompts, token reinforcers, and verbal praise for the youth's social behavior were presented (baseline and training sessions), and one in which prompts were absent and only verbal praise was presented (probe sessions).
Five new subjects were recruited No-Motion Groupp) and trained with the same procedure that was used for the Direction-Training Group, with the exception that no moving-dots were presented during the training sessions.
However, the work volume and intensity proposed in the present study for the training sessions were within a safe range that promoted an increase in isotonic strength in E10 without producing significant damage to skeletal muscle that would lead to an increase in serum levels of CK, TNF-α or cortisol.
Scenarios presented during the 12 training sessions were similar to tasks in everyday life.
Therefore, the training stimuli were not presented for the prolonged training sessions that are typically used to induce learning, but rather the VOR-increase and VOR-decrease training stimuli were alternated in brief, 60 90 s blocks, so that the neural responses to the two kinds of training stimuli could be directly compared in the same neurons.
