I am a professional volleyball player wanting breast augmentation. What procedure would be best for my lifestyle? (photo)

I would suggest having a conservative sized implant placed under the muscle or in a dual plane position. A conservative sized implant will all depend upon your chest wall size and frame. I have never placed an implant for a professional volleyball player, but have done so for other professional athletes including basketball players and the type of muscle movement and activity is not likely to be too much different. Having an implant under the muscle will not restrict your ability to play your sport at an elite level nor will it interfere with your training. 

and be beneficial to your appearances.  You should discuss your concerns and expectations with your chosen surgeon and understand the logic behind the recommendations and choose what will work best for you.
