The javelin competition at the 1972 Games was the closest in Olympic history. Germany's Klaus Wolfermann had taken the lead from Lūsis in the fifth round with an Olympic Record throw of 90.48 meters. Then, in the sixth and final round, Lūsis let fly with a very long effort that measured at 90.46 meters - Wolfermann's two-centimeter margin was, at the time, the smallest unit of measurement used in javelin competitions.
As of 2020[update], he remains the only Latvian to have won an all three classes of Olympic medals (gold, silver and bronze) over the span of his career. Lūsis set two world records in javelin throw, of 91.68 m in 1968 and of 93.80 m in 1972. He is also a 4-time European champion. In 1987 IAAF named him the greatest javelin thrower in history.
