In a questionnaire distributed to coaches and development staff of 25 federations other than judo that participated in last summer's London Olympics, respondents from two additional federations said they had witnessed physical abuse. Of the 55 individuals in 25 federations who were sent questionnaires by e-mail, 34 individuals from 21 different federations responded.

From the two sports in which physical abuse was observed, one respondent answered both "yes" and "no" to a question about employing physical abuse himself.
