pretty much, yeah.
and to answer the question: I'm not much of an expert on cardio in general, but I've been swimming for quite some time now... I find that the best cardio workout is a mix of both.. the one I did this morning went something like this:
500M warmup, easy swim for first 400, moderate for last 100
5X25M sprint, 5-10 seconds of rest between each
200M light swim
5X25M sprint, 5-10 seconds of rest between each
200M light swim
5X50M sprint, 5-10 seconds of rest between each
200M light swim
5X50M sprint, 5-10 seconds of rest between each
200M light swim
Pyramid, moderate pace, 5 seconds of rest between each
(pyramid is 25M then 50M then 75M then 100M then back down to 25 again)
then another 500M light swim to cool down. (I only did 200 of this, I started late and had to get to class)
but providing you are a decent swimmer, I find the above to be a great endurance/cardio workout. it's
low impact and keeps your
heart rate up.
Hope it helps
