"Adapting to conditions is important. The conditions need to be suitable for us. So we are leaving early. We don't know how it would be. There will be drift and we will be practising for a week so we will be used to the court. So it will be an important week in Rio," Sindhu, who won two bronze medals at World championships in 2013 and 2014, told PTI.
"I have beaten all of them in the past and it gives me confidence but then it gets tougher and tougher as we play them again because they know our strokes and we know there game, so it is all about changing the strategy on the court. That would be the key," she said.
The three-time Macau Open winner will be participating in her maiden Olympics.

"This season, I played so many tournament as it was a crucial year. Sometimes I was playing well and sometimes not. I learnt from my mistakes. I played against all of them, all the top players. Everybody has a different style of play and it was a good learning experience and I think it will help at the Olympics."
Asked if she feels the pressure, Sindhu said: "Pressure is always there. But we need not get bogged down by that. It is part of an athlete's life. I am really excited to play at Olympics. We are leaving on August 2nd. The draws are also out."
Sindhu has been clubbed with Commonwealth Games champion Michelle Li of Canada and Hungary's Laura Sarosi in Group M. If she crosses the league stage, the Indian will have to overcome Tai Tzu Ying of Chinese Taipei and China's Yihan Wang to just make it to the semis.
Talking about Chinese Taipei's Tai Tzu Ying, Sindhu said: "She is a difficult opponent, her game is very different from others and she has good strokes. It is not that she is unbeatable. If I am ready for it I can beat her."
Sindhu said from now on, the training and preparation will be specific to the players that she would be facing in the mega-event.
