All about base excess â to BE or not to BE. In 1948, Singer and Hastings introduced the concept of buffer base (BB). The change in BB from normal was called deltaBB (Î´BB). This change in BB was an expression of the non-respiratory (metabolic) component of an acid-base disturbance.
Empirically from http://www.usaswimming.org/_Rain..., free style is the fastest stroke. This is also called the front crawl (see Front crawl). However as Swimming stroke notes, there are at least 6 variations of that technique.
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
