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.
You can swim other strokes during a 100-meter swim, but a decent time will change according to your ability with that stroke. For example, swimming a 100-meter freestyle in 70 seconds is fast, but swimming the same time using breaststroke or butterfly is extremely fast.imes. Regardless of what stroke you swim, one minute is often a valiant goal. The 60-second barrier in a 100-meter swim requires hard work and training. Other aspects of a swimmer, such as age, gender and stroke dictate how decent a time will be.
