backstroke

We see that in backstroke, so underwater swimming must be faster than backstroke.

The rule is only on the IM; freestyle can't be butterfly, backstroke, or breaststroke.

In other words, before this rule they mostly were not performing the backstroke, despite the name of the race.

But I don't understand: the rule says swimmers performing the backstroke have to surface, and when I look up backstroke, it is someone laying on their back?

If you watched swimming competitions earlier than the 1980s you'd see Fish Kicking swimmers in freestyle and backstroke competitions, too.

Once you've got floating mastered, an elementary backstroke will get you moving slowly through the water without much caloric expenditure.

And the way that starts and turns work in backstroke still puts you underwater at the start of each lap.

As per the article there has been a 15m underwater limit off each wall in butterfly, freestyle, and backstroke since 1998.

Though the article doesn't state it there was a 10m limit in backstroke 1988, that was relaxed to 15m in 1991.

I was finally able to swim the length of the pool using the side stroke, which along with the backstroke is the only thing I can barely manage.

Probably a better comparison is world record for 50m backstroke which is 24.04.

Which doesn't sound like either of these The updated rules essentially say a swimmer in a "backstroke race" must perform the backstroke for 35 meters.

To me, the separation is similar to using the term "backstroke" over the term "swimming."
