supposedly banned substances; bodybuilders who refuse to take banned substances now compete in natural bodybuilding leagues. Cheating may also be seen in coaching. One of the most common forms of this is the use of bribery and kickbacks in the player recruitment process. Such practices are widespread all across athletics, and are particularly visible in college sports recruitment. Another common form of cheating in coaching is profiteering in association with gamblers and match fixing. The most famous coach of the University of Nevada, Las Vegas Runnin' Rebels basketball team, Jerry Tarkanian, was accused of both recruitment fraud and gambling fraud over the course of his career and was the subject of intense NCAA scrutiny. Another form of this involves a team coach or other manager undertaking corporate espionage or another form of prohibited spying in order to obtain details about other teams' strategies and tactics. The 2007 New England Patriots videotaping controversy is an example of this, in which the New England Patriots were found to have videotaped an opposing team from an unapproved location while trying to obtain defensive signals.

An example of cheating via judging collusion occurred in the 2002 Winter Olympics figure skating scandal when the Russian team was awarded a gold medal over the Canadian team in an alleged vote-swapping judging deal; the Canadian team's silver medals were eventually upgraded to gold at a second awards ceremony and the French judge was suspended for misconduct. The head of the French skating federation was later also suspended, and both were banned from the 2006 Olympic Games. The International Skating Union modified its judging system as a result of this case. Cheating is also used to refer to movements in strength training that transfer weight from an isolated or fatigued muscle group to a different or fresh muscle group. This allows the cheater to move an initial greater weight (if the cheating continues through an entire training set) or to continue exercising past the point of muscular exhaustion (if
