For the first time, athletes at an Olympic Games took part in educational awareness programmes, which highlighted a number of things that they can "become victim to".

Featuring real-life scenarios, the eLearning tool was available to athletes in the Olympic Village’s International Olympic Committee (IOC) Space, on their mobile phones and online.

A statement on the FIH website backed the measure and said the organisation had played a "leading" role.

"FIH was very happy to be one of the pioneering sports because we are totally dedicated to keeping hockey a sport that is inclusive, sustainable and, above all, has integrity," said the FIH's chief executive Kelly Fairweather.

"We are fully supportive of the IOC and its measures to combat illegal activity - be it doping, suspicious betting behaviour or anything else that threatens the integrity of the Games as a whole or of an individual sport.

"The decision to include the athletes in the battle to maintain the integrity of the Games is the sensible way forward.

"It helps to highlight potential pitfalls that athletes can succumb to - often through ignorance in the first instance.

"The eLearning platform is a powerful tool that will help athletes recognise situations and respond correctly."

Other measures that were in place for the Rio Games included a fully operational Joint Integrity Intelligence Unit (JIIU), working in collaboration with experts from the Rio 2016 Organising Committee, as well as a reinforced Integrity Betting Intelligence System (IBIS).

The JIIU has been responsible for the prevention, monitoring and assessment of any unethical activity related to the Olympic Games, and has been supported by the Department of Federal Police (DPF), the Secretariat of Security for Major Events (SESGE) and, in the case of any criminal activities, the International Criminal Police Organisation (INTERPOL).

A total of 1,224 top-level hockey athletes and support personnel from 25 different countries have completed either the World Anti-Doping Agency's (WADA) on-line anti-doping education programme “ALPHA”, or a course led by a National Anti-Doping Organisation (NADO).

Those undertaking the educational course included all 432 athletes going to Rio.

As part of its "Hockey Revolution", FIH aims to "build a recognised, powerful image" for hockey and at the core of this is "providing a clean, ethical sport for millions to enjoy".
