The pair of Jwala Gutta and V Diju lost to Tontowi Ahmad and Liliyana Natsir of Indonesia in straight games. The final score was 21-16, 21-12 in favour of the Indonesian combination. It was a one-sided affair as the contest was over in just 25 minutes.
"I was pretty prepared but things didn't work out according to plan. But you know, it's the first day and the first match. I just need to focus on tomorrow," Jwala said.
"I think I was pretty good. I really don't know what happened. I never feared them. We've beaten them before but we do need to be more attacking. We were playing the game that they wanted us to," Jwala added.
Jwala was upset that she had to play two matches in a day. "It's pretty shocking for it to happen at the Olympics - such a big event. I have to play my second match today so of course it will affect me."
Diju said: "In this match, we were playing defensively - we will be more attacking tomorrow against the Danish pair."
Indians, who are in Group C, will have two more matches in the preliminary stage. Next they face Thomas Laybourn and Kamilla Rytter Juhl of Denmark on Sunday.
The top two teams from each group will progress to last eight stage.
Later in the day, Jwala and Ashwini Ponnappa will be in action in the women's doubles. They play Reika Kakiiwa and Mizuki Fujii of Japan.
