Russian long jumpers Margarita Goncharova and Evgenii Torsunov both set world record marks on the second day of action at the International Paralympic Committee (IPC) Athletics Grand Prix in Berlin.
Goncharova, the world, Paralympic and European long jump champion in the T38 category, leapt 5.10 metres in the first round before producing increasing that to 5.22m jump.
It added 26 centimetres on to the world record mark set by Ukraine's Inna Stryzhak three years ago.
This continued the form she had shown in the sprint events, where she got the better of Brazilian rival Veronica Hipolito over 100m at the Friedrich Ludwig Jahn Sportpark with a time of 13.51.
"I feel very happy about this result and my performance," said the 24-year-old afterwards.
"It is good preparation ahead of the World Championships in October [in Doha] but still I have some months for preparation so I need to do even more work on my results.
"But I feel very positive."
Despite making his debut in a Russian vest, Torsunov showed no signs of inexperience in breaking the second world record of the night, smashing the T36 best three times en route to victory.
He added 13 centimetres on to the previous mark set by Brazil's Rodrigo Parreira da Silva two months ago at the São Paulo Grand Prix, reaching 5.66m with his fifth jump.
He claimed afterwards it gave him "hope and confidence for the future".
There was a third world record for Germany's Franzis Liebhardt in the shot put to the delight of the home fans, as he set a new F37 category mark of 12.2m2 to add a minuscule two centimetres to the distanced managed by Mi Na of China at the London 2012 Paralympic Games.
South Africa's Jonathan Ntuta was another dominant winner, crossing the line in the T12 100 metres in 11.30sec.
But there was a shock in the T36 category as Britain's Paralympic and European silver medallist Graeme Ballard got the better of the man who beat him in each of those events, Evgenii Shvetcov of Russia, to win in 12.49.
"I'm absolutely chuffed," he said.
"It's my first win over Shvetcov ever."
Chermen Kobesov in the T37 category, Andrey Koptev in the T11/35 and Anton Prokhorov in the T42 were other Russian winners over 100m,.
Germany's Felix Streng, meanwhile, secured a solid T43/44 victory with a time of 11.20 despite blustery and damp weather.
Elsewhere, Mexico's Daniela Velasco Maldonado produced the middle-distance performance of the day, racing home well clear of the field over 800m in 2:17.91, a new world lead for the T12 Para-athlete, while Poland's Bartosz Tyskowski threw a F41 world lead of 44.36 in his final attempt in the discus.
