Investigation taken from the brand new 20 m shuttle manage test was indeed translated towards a score (maximum from 10) centered on Japanese normative data twenty-six . Body mass index and you can exercise have been analyzed from the real degree teachers.

The youngsters done a survey towards their day-after-day life habits, including get it done models, display big date, and studying years. Particular information on brand new questionnaire are provided on the Secondary Approach.
