Bolt tore around the bend as attention quickly switched to the clock, but the 29-year-old – just two days shy of his 30th birthday – looked heavy in the home straight and posted a mediocre time by his lofty standards.
"I wasn’t happy with the time," Bolt admitted to BBC Sport afterwards. "I’m getting older, I’m not as young and fresh.
"I’m excited that I got the gold medal. That’s the main thing."

Meanwhile, Gemili was disconsolate after he missed a spot on the podium by three thousandths of a second.
The 22-year-old produced a fine run from lane two, but was unable to sneak ahead of Lemaitre as he finished an agonising fourth.
"I am heartbroken. I put so much into that run," he said.
"I lost my form at the end and to get so close at the end is heartbreaking. I am absolutely gutted."
