Training and Detraining Effects Associated with the D2 Mode B Assessment
The purpose of this study is to examine the changes in performance on the Dynavision D2 Mode B Training assessment during a period of continuous training in addition to measuring how quickly performance is recovered following a period of detraining (no training).
This study will consist of 32 visits for a total of approximately 9 hours over 5-10 weeks. The first visit will consist of informed consent and eligibility questionnaires. The second visit will consist of anthropometrics (height, weight, and body composition), followed by familiarization with the training device. After this visit, you will have 15 training visits (Visits 3-15) using the Dynavision D2 Mode B Training assessment, followed by a period of no visits that could be from 1 week to 4 weeks, and then have 15 more identical re-training visits (visits 16-32). Each training and re-training visit will take approximately 15 minutes and will consist of two D2 Mode B Assessments and completion of a visual analog scale to assess alertness. Visits 3-15 and 16-32 must be separated by a minimum of 24 hours and no more than 72 hours.
