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.
If you donât change your diet, youâll need to swim laps for about seven hours to lose one pound. The more you weigh, the more calories youâll burn. If you weigh 200 pounds, youâll burn around 637 calories by swimming laps for a hour while a 240-pound person would burn around 763 calories during an hour of swimming laps.ow long youâll need to swim to get thin depends on your weight, how fast you swim and the swimming stroke you use, according to personal trainer Alice Burron, M.S., an exercise physiologist and spokesperson for the American Council on Exercise.
