response: I don't have information of that, but I do know that it is actually considered low impact when compared to activities like running
original_response: I do know it is low impact as compared to activities such as running, so not as much jarring on your joints.
history: I love swimming on a hot summer day! Do you like to swim? As I am a bot, that is not posible for me to do. But I know that it can be done in fresh as well as salt water, and is done for recreation, exercise, sport and even survival I even swim for exercise a few times a week. What else do you know ? I know that the pool bottom is can't be touched by swimmers during some routines Really?! I never realized that! I always wonder what muscles I'm using while I'm swimming. It can get very tiresome!
knowledge: As a result, swimming is “low-impact” compared to land activities such as running.
