The whip can now be used a maximum of seven times in a thoroughbred race and eight times in a jump race, including only five times in the last furlong or after the last obstacle. This is roughly half the number of times a whip could be used previously.
Penalties will increase for those who break the rules more than once. Punishment for a second offense will be twice as harsh as the first.
"Jockeys are pleased the Authority has recognized the whip is an important tool of the trade and that these changes will ultimately help protect the integrity of the sport," said Kevin Darley, chief executive of the Professional Jockeys Association.
The review was compiled with input from animal welfare bodies, including the Royal Society for the Prevention of Cruelty to Animals.
"We will be monitoring their implementation to see if they have made a real difference to horse welfare," RSPCA equine consultant David Muir said. "We hope these changes will mean that the few jockeys who have misused the whip will think twice in future."
