Abdul Latif Romly and Leilia Adzhametova among those breaking ground at the Paralympic Games in Brazil

Several world records were set during the Sunday morning session at the Paralympics in Rio, including one for Petrucio Ferreira dos Santos of the host nation.

The Brazilian enthused the home crowd with victory in a world record of 10.57 in the 100m T45-7, the classification for athletes with upper-limb impairment.

He had clocked 10.67 in his heat, which broke the 24-year-old T47 world record held by Ajibola Adeoye.

Another host nation medal went to Yohannson Nascimento, who took bronze with 10.79, which broke his T45 world record from London. He shared that time with Poland’s silver medallist Michal Derus (T47).

Abdul Latif Romly of Malaysia improved his world record three times to take gold in the long jump T20, the classification for intellectual disability.

In the second round, Romly went out to 7.47m, adding 12cm to the global mark which won him the world title last year. He jumped 7.54m in the next and 7.60m in the fifth round, the latter into a headwind of 1.2m/sec. His final jump of 7.49m completed a great series as the next best athlete, Croatia’s Zoran Talic, was back on 7.12m.

In the T13 class for visually impaired athletes, Leilia Adzhametova of Ukraine took seven hundredths off the 100m world record she set in qualifying, her 11.79 putting her comfortably in front of the runner-up, South Africa’s Ilse Hayes (11.91).

Yao Juan headed a China one-two in the women’s discus F44 with a world record 44.53m. Yang Yue was second with 43.47m as Cuba’s Noraivis de la Heras Chibas took bronze with 32.47m.

South Africa’s Charl du Toit just missed his world record in the 100m T37 with 11.45, overtaking the fast-starting Mostafa Mohamed of Egypt, who gained silver in 11.54 – a time he shared with bronze-winner Fanie der Merwe of South Africa. Du Toit was ninth in this cerebral palsy classification event in London and third at the IPC Worlds last year.

Britain’s Rhys Jones was sixth with 11.94 and said: “To come sixth in the world in a class field such as that is amazing. There were Paralympic and world records in the heats, and that was so quick again. I thought London (2012) was quick but four years on the class has evolved.”

Ireland’s Michael McKillop secured his fourth Paralympic gold, clocking 4:12.11 in the 1500m T37.  The man who won the 800m in 2008 and both the 800m and 1500m in 2012, went to the front with 700m remaining and only Canada’s Liam Stanley went with him. However, McKillop pulled away over the final lap for an easy victory as Stanley clocked 4:16.72.

Morocca’s Azeddine Nouiri defended his title in the shot F34 as he went out to 11.28m. Qatar’s Abdulrahman Abdulrahman took silver with 11.15m. Colombia’s Mauricio Valencio won the bronze.

The javelin F41 for athletes with a short stature disability led to an Iraq one-two, headed by Kovan Abdulraheem with 42.85m. While the F41 competitors were down on the world record, a global mark fell to Iraqi F40 Ahmed Naas (35.29m), who was ninth overall. In sixth was Britain’s Kyron Duke, who followed up his fifth in the shot with a British record 39.30m.

Duke said: “I can’t ask for anything better. It is not a medal but it is as good as. I have done my best and come out at the top of my game.”

In a tactical 5000m T54, Prawat Wahoram of Thailand took his sixth Paralympic gold as he stopped the clock on 1:01.71. Switzerland’s Marcel Hug gained silver and Australia’s Kurt Fearnley bronze. Wahoram’s first Paralympic medals came in the 5000m and 10,000m in Sydney 2000 and he followed that with two team golds in 2004 and the 5000m in 2008.

Pongsakorn Paeyo gained Thailand’s second wheelchair gold of the day, clocking 47.91 in the 400m T53 to beat 100m winner Brent Lakatos (48.53). Britain’s Moatez Jomni was eighth and last with 51.53.

American Tatyana McFadden remains on course for seven medals at these Paralympics, the wheelchair athlete leading the qualifiers for the 400m T54 final with 53.17.

Ukraine’s Ihor Tsvietov, who won the 100m T35 on Friday, began his 200m bid by heading the qualified athletes for the final with a Paralympic record 25.64. Also qualifying for the final was Britain’s Jordan Howe, who gained some compensation for his false-start DQ in the 100m, as he was third in his heat with 27.61.

“It is a tremendous way to bounce back,” he said. I couldn’t have asked for better – I was with the guys all the way through. After the 100m, I was devastated because that was my main event but now I put all my focus on the 200m and I am ready to go.”

Sunday night’s action begins at 9.30pm British time.
