How many more calories can you burn by running versus swimming? 

Both strengthen muscles and enhance cardiovascular fitness and endurance, but which burns more calories?  

Speed, workout length, and kind of run or swim affect this measure, making it difficult to validate.

Running has similar advantages, and does it develop muscle? 

It stimulates muscular growth, strengthens legs, and increases bone density through bone loading.  

Calorie burn, like other activity, relies on intensity, workout length, and biological parameters including age, weight, sex, hormones, and more.
