Akilles and Matti Järvinen are the only brothers in the history of athletics who simultaneously (1930–1932) held a world record: Akilles in the decathlon, Matti in the javelin .

According to this evaluation, Akilles Järvinen would have had 150 points in 1928 and 120 points in 1932 over Paavo Yrjölä and Jim Bausch respectively .
Akilles Järvinen was only 37 years old. He was killed in the crash of a PY-37 that was on a training flight with him as co-pilot.
