A handout footage given by the hospital shows members of a Thai youth football team being cheered by hospital staff.
The boys, aged 11 to 16, and their 25-year-old coach sparked an global rescue effort after they became trapped inside the flooded Tham Luang cave complex in Chiang Rai.
The boys, who sported crisp haircuts, had gained 3 kg (6.6 lb) each on average since the rescue, and ran through confidence-building exercises ahead of Wednesday's event, the hospital director said.

The boys, aged 11 to 16, and their 25-year-old coach got into difficulties after exploring the Tham Luang cave complex after football practice on 23 June.

"When they said "hello" to me, I said 'hello" back.
They also spoke of feeling guilty about the death of a former Thai Navy SEAL during the rescue effort. Last week, the Thai Navy SEALs released video showing just how hard and risky that rescue mission was as they raced to save the team from more potential flooding. But a rainy season downpour flooded the tunnels, trapping them as they took shelter on a shelf of the dark cave.
The group had no food on a trip which they thought would only last an hour in the cave.
"I told everyone fight on, don't despair", said one boy, describing how the group had battled to stay alive.
"We tried to dig out as we thought we can not only wait for authorities to get us", he said. Ekkapol said he was the one, as he could not understand English.
On Wednesday, the team was discharged from hospital nearly a week after their three-day rescue.
"I stopped thinking about food because it would make me even hungrier", the youngest one said.
