Below is an example of how shapefiles will appear in ArcCatalog. You can also see the dBASE file (that may be associated with a shapefile). All files that have the file extensions .txt, .asc, .csv, or .tab appear in ArcCatalog as text files by default.
Variables: Intensity, Weight and Time. The amount of calories that you burn when swimming this stroke will depend a lot on the intensity that you put forth, how much you weigh, and the amount of time that you swim. The more you weigh and the harder that you swim, the higher the amount of calories you will burn doing the elementary backstroke. A 120-pound person swimming an easy pace will burn 120 to 220 calories in 30 minutes. A 200-pound person swimming at a vigorous pace will burn 200 to 400 calories in 30 minutes.
Because you burn more calories when you swim faster, covering more distance, it makes sense that the fastest swim stroke has the potential to burn the most calories. Holland says this is the freestyle stroke. But, that doesnât mean you should opt for the freestyle every time you get into the pool. As well as speed, the amount of calories you burn also comes down to duration and frequency, says Holland. âSo if you enjoy the breaststroke more than freestyle, you may swim longer and be more consistent utilizing that stroke, meaning more total calories burned.â
