I think it will still be affected, at least it will affect your physical recovery and reduce the effect of your fitness training. I don't know how your fitness is arranged. You should practice every other day 2-3 days a week and exercise your whole body muscles every day. You have been exercising for a year, and according to your meaning, fitness is more important than swimming, so I think you should consult the coach in the gym and ask him to follow you for swimming training. Help you make a reasonable fitness plan. In fact, I think that if we pay attention to the fitness effect, we can take swimming training as the relaxation and recovery of fitness. Don't train too hard, just relax and it won't affect your fitness too much. Don't swim too hard. It is best to swim in a short distance, pursue speed and use explosive force! Swimming slowly and far for a long time will become aerobic exercise and consume muscles.
