LONDON — From golf to roller speedskating, the seven sports vying for inclusion in the 2016 Summer Games have submitted their proposals to the International Olympic Committee.

Baseball, softball, rugby sevens, squash and karate also sent in their documents by this week's deadline providing answers to 80 questions, the IOC said Thursday.

The seven sports are competing for a maximum of two openings on the 2016 program. The decision will be made in October at the IOC session in Copenhagen, where the 2016 Olympic host city will also be selected from Chicago, Tokyo, Madrid and Rio de Janeiro.

The IOC program commission will evaluate the sports federations' documents and submit a preliminary report to the executive board in June.

In Copenhagen, the IOC general assembly will vote en bloc on the continuation of the existing 26 sports. The voting procedure for the potential addition of one or two new sports has yet to be finalized.

Rugby sevens, squash, golf, karate and roller sports were each considered for inclusion in the 2005 vote but all failed to win a required two-thirds majority. The system has since been changed to require only a simple majority for addition of new sports.

The International Golf Federation is proposing a 72-hole stroke play Olympic tournament for men and women, with 60 players in each field. In the case of a tie, a three-hole playoff would be held to determine the medalists.

The top 15 players in the world rankings would qualify automatically.

Golf organizations have agreed to adjust their summer schedules to ensure that no major championships conflict with the Games.

Softball, meanwhile, continues to distance itself from baseball, stressing that its best players all go to the Olympics and that the sport has had no positive doping tests at the elite level.

The International Baseball Federation insists its Olympic hopes should not be hurt by the high-profile doping controversies in Major League Baseball involving such stars as Alex Rodriguez, Barry Bonds and Roger Clemens.

Rugby was played at the 1900, 1908, 1920 and 1924 Olympics.
