In 1972, Henning broke the world records on the 500*m and the 1,000*m, which made her the favourite on those distances at the 1972 Winter Olympics in Sapporo. During her 500*m race against Sylvia Burka at those Olympics, Henning was obstructed at the crossing by Burka, but she still set the fastest time and a new Olympic record (43.70).
