The time Ayyasamy clocked was immediately significant as it matched the qualifying guidelines of 49.45 seconds set by the AFI to determine the Indian team for the Commonwealth Games at Gold Coast.
"I am really happy with the result," Ayyasamy said after the win. "I was suffering from typhoid till ten days before. But I have worked hard with my coach to recover and train. It is a very good feeling to break national record and qualify for CWG," he said.
Arpinder Singh earned the right to improve on the bronze medal he won in the triple jump at the Glasgow Games in 2014 by clearing 16.61m to finish 1 cm above the qualifying guidelines of 16.60m set by the AFI.
Arpinder was in danger of finishing outside the qualification guidelines but managed to find the mark in his fifth jump which was also his final legal jump of the competition.
Hima Das of Assam, who had already qualified in'the women's 400m race earlier, blitzed the field in the 200m event winning in a credible time of 23.37 seconds which was just.07 seconds shy of the meet record of 23.30 set by PT Usha in 1998.
Although Das missed the CWG qualifying guidelines of 22.60 seconds, it was a credible performance by the 18 year old who finished more than a second clear of second place PJ Sneha (24.47 seconds).
Another strong performance that fell short of the CWG qualifying guidelines came in the 1500m through Jinson Johnson, who clocked 3.39:69 seconds that was just 0.19 seconds shy of the qualifying guidelines of 3:39:50 seconds.
Johnsons mark was also a new meet record, erasing the old mark of 3:41:12 seconds recorded 11 years ago by Chatholi Hamza.
