Hello, you'd better not go swimming immediately after running. Oh, you must rest for more than half an hour before you can go swimming. Because after running, first, the heart rate is relatively fast and shortness of breath; Second, hypothermia and muscle tension; Third, excessive water loss caused by running and sweating; So it may be dangerous to go swimming immediately after running, for the above reasons! Water, sugar and salt should be added during rest. Don't swim too fast after entering the water, and don't push your calves too hard. You should use a more soothing method. I wish you a happy fitness!
