IKMF competition rule. Relay Race category.
Before the relay race, participants line up in teams in the order of their relay legs. 15 seconds before the start of the next leg, the judge allows the next participant to come forward. The transfer is made after the 'change' command. The participant who has just finished must place the kettlebell(s) on the platform. If a participant fixates the kettlebell(s) after the 'change' command, the last rep will not count.
See the interactive comparison on KETTLEBELL MONSTER™ for filterable views and more detail.
