Besides his Olympic gold, Järvinen is remembered for his numerous world records. During the years from 1930 to 1936, he broke the javelin throw world record a record ten times in a row. He also became the European champion in 1934, setting a new world record with 76.66 m, and defended his title successfully in 1938. In the 1936 Summer Olympics, Järvinen finished fifth. Järvinen continued throwing after World War II, recording a 71.70-metre throw in 1945.
In 1939 Jarvinen, with his fellow javelin thrower Yrjö Nikkanen, served together on the Karelian Isthmus, where they trained soldiers in throwing hand grenades. After the War he became a noted economic councillor.
