More than 3,000 people will eventfully be selected for roles at the new event in the Colombian city.

Interested candidates have been told they could "help make history" after the idea for the Junior Pan American Games was first approved in 2018.

Cali was chosen as the first host in March last year in front of Santa Ana in El Salvador and Monterrey in Mexico.

The city staged the senior Pan American Games in 1971 and the World Games in 2013.

"Volunteers have always been the heart of each of the Pan American Games," said Panam Sports President Neven Ilic.  

"They represent the joy, the excitement, the feeling, the desire and the motivation of athletes, coaches and leaders. 

"They are the engine of the event. 

"Without them, the Games could not be held. 

"From now on I am calling on all Colombian youth and adults to sign up to be able to live this incredible experience of being a volunteer. 

"They will have an amazing time, they will meet great athletes from throughout the continent, and with their contribution, they will help Colombia and all of the Americas create an unforgettable sports festival."

In March, 30 sports were confirmed for the Cali 2021 programme.

More than 4,000 athletes are set to compete between September 9 and 19.

Dates in June had originally been planned but Panam Sports moved the event back in response to the COVID-19 pandemic.

Volunteers must be at least 16-years-old on January 1 of next year.

Those under the age of 18 need parental consent to sign-up.
