Hey I don't really get it. When I shot sports I never had this problem. Most of the time your shutterspeed is high enough to eliminate any movement from yourself. I found it more hard to concentrate on composure after rushing to another spot. Quickly find out what I want to shoot and what lighting there is and what background is available.


But if you really get out of breath and your photos suffer, the best advice would be a little more exercise to be honest. At least that is what I can think of.


The way I get my steady shots, like slower than 1/30 (tried it with the 100-400 with IS on two days ago and shot 1 sharp picture at 1/6 sec at 400mm, good keeper-rate at 1/30 at 400mm) are mostly by holding the camera with my right hand, supporting the lens with the left hand with the elbow against my body. Taking a deep breath and easily breathing out. I found out that for me keeping my breath doesn't work. But this technique practically works only for still objects.


I hope it helps you a bit.
