A detailed history of the early editions of the Bolivarian Games between 1938 and 1989 was published in a book written (in Spanish) by José Gamarra Zorrilla, former president of the Bolivian Olympic Committee, and first president (1976–1982) of ODESUR.[1] Gold medal winners from Ecuador were published by the Comité Olímpico Ecuatoriano.[2]
A total of 33 events were contested, 23 by men and 10 by women. Unusually,
cross country events (individual and team) were part of the games.
