The United States beat China 2-0 Tuesday to win the Four Nations tournament, a warm-up for the FIFA Women's World Cup in China later this year.
The American women dominated the match, a replay of the 1999 World Cup final and 1996 Olympic final, and went ahead through a rocket from defender Lori Chalupny in first-half injury time.
Nastasha Kai put the game beyond the Chinese in the 56 minute when she pounced on a rebound to put the ball past goalie Han Wenxia.
Ma suddenly left training early this month, returning to his home town of Shanghai for check-ups on a heart problem, while reports swirled that he would be replaced by his team's German advisor Eckhard Krautzun.
Wang Haiming, who is also in the running for the job if Ma's health fails him, led the Chinese side during the Four Nations tournament.
However Ma said he had now recovered and was hoping to return to his post soon.
"I have had this check up and now I'm feeling pretty good, so as long as my health allows I hope to quickly return to Guangzhou and even take up my duties," Ma told Sina.com's football website.
Krautzun was also struck with a stomach complaint while working with the team in Guangzhou and has returned to Germany to recuperate, press reports said.
