Zitat von Hafu

Hältst du die vom Autor angegebene Rücklaufquote von schier unglaublichen 99% (d.h. von 100 Leuten die angefangen haben, einen Bogen auszufüllen, hat nur ein einziger danach den Bogen nicht komplett und sorgfältig ausgefüllt zurückgegeben) für nachvollziehbar?

Es waren sogar 99,7% (2987 von 2997), die den Bogen wieder abgegeben haben. Allerdings wurden die RRT Fragen nicht von allen beantwortet.

Response Rate, Biographical Data, and Training
Characteristics of the Participants

2,997 questionnaires were distributed and 2,987 (99.7%) were returned.
From these returned questionnaires, 31.1% (N=934) were collected at the European Championship in Frankfurt, 32.6% (N=974) in Regensburg, and 36.1% (N=1,079) at the European Championship 70.3 in Wiesbaden.

The percentage of responses to the two RRT questions were 90.5% (N=2,702) for physical doping and 91.6% (N=2,737) for cognitive doping.

5.4% of the participants (N=162) completed the first part of the questionnaire but not the two sensitive RRT questions.

Most athletes were male (N=2,576, 87.3%) and with mean age of 39.5 years (SD: +-9.2; range 18–79). Table 4 contains the biographical data of all athletes and Table 5 information about their training schedule
