Answer 1

Running the Boston Marathon is 26 miles and a runner loses 2,500 calories during the 2 hour run.   You are swimming a little over 1/2 mile.  So you are burning a few calories but you aren't losing any weight.   Your heart and your muscles are being made stronger by the exercise and it is adding years to your life.

Answer 2

doing something for 1 time isnt really going to do much.. you have to be consistent with it...
