At the 2020 Olympics, the IOC has approved additional events, specifically three-on-three basketball and mixed gender relays in track and in swimming.
Events confirmed Friday are in addition to decisions last August to include sports climbing, skateboarding, surfing, baseball and softball, and karate in the Tokyo program. Paris is favourite for the 2024 Games ahead of Los Angeles, but the one of the either will get to host the 2028 Olympics.
Women's boxing, which made its debut in the 2012 London Olympics, had three weight classes - 51kg, 60kg and 75kg - in the last two Olympics.
"The fascinating new events that we approved today, together with the five new sports that were added to the Tokyo 2020 programme past year, represent a step-change in the Olympic programme", said the IOC President Thomas Bach.
Three-on-three basketball is an example of the IOC's focus on youth and urban sports.
The refreshed schedule, which takes the total number of male-and-female events at a Games from nine to 18, will include a mixed 4x400m for athletics, a 4x100m medley for swimming, and a mixed team event for the triathlon. A meeting of the full International Olympic Committee membership from July 11-12 in Lausanne can ratify the board's request.
The action by the IOC's executive board did not make clear which city will get the 2024 games and which will be awarded the 2028 iteration - a decision that is not expected until September.
"With no new permanent venues to build and unwavering public support, Los Angeles is an eternal Olympic city and an ideal partner for the IOC".
International Olympic Committee executives also cut the number of male weightliftings and wrestlers by 120, in keeping with their goal of reducing the predominance of sports that have been most blighted by doping.
That's also when the host city for the 2024 Summer Games will be announced - either Paris or Los Angeles.
Track cycling will add men's and women's madison races in 2020 in a velodrome about 130 kilometers (80 miles) outside Tokyo and swimming will add men's 800-meter freestyle and women's 1,500 freestyle.
The event was featured in the recent world championships in Germany.
Wrestling will lose 56 places, sailing and shooting will each lose 30 and swimming will have 22 fewer. "We believe that the IOC is acting in the best interests of the Olympic Movement and the future of the Games in taking these steps". Both cities seek to follow London as three-time Olympic hosts. Less publicized but no less important to golf fans, however, was the IOC's announcement that all 28 sports from the 2016 Rio program will remain on in 2024, meaning golf will return beyond its initial two Games guarantee.
