What constitutes as being the recommendation for “cardio exercise”?

Greetings friends,



I think that it has been conveyed to me throughout the years that in order to maintain a healthy life style, that we as human beings are to periodically engage in “cardio exercise”. (?)



If what I have just written in the preceding sentence above is not totally correct, then please feel free to correct me. :-)



Please allow me to confess up front that I am perhaps going on antiquated information. I therefore wish to “update myself”. Thus, if someone has the patience or diligence to respond to my 4 different questions below, I would be elated.



1. In my somewhat limited knowledge regarding health and exercise, I recall several years ago how it always seemed to be conveyed to me, something along the lines, that one is to engage in a continuous or constant activity, be it jogging, running, or swimming, for at least 15 to 20 contiguous minutes (without any pause or rest during this 15 to 20 minutes), for 3 times per week. Is this still considered as being correct? Or, is this now considered antiquated information?



2. If the above is correct, may I substitute, for instance, roller blading or bicycling, as one of the activities (instead of, for instance, jogging, running, or swimming) to be engaged in for 15 to 20 contiguous minutes?



3. I enjoy swimming. However, I should qualify that statement. I am not crazy about, what I consider, somewhat boring, lap swimming. That is, I am not crazy about, for instance, where one is swimming, continuously or contiguously back and forth within the pool with absolutely no pause between laps, at a moderate to moderately slow pace, for several continuous minutes. Rather, I prefer, instead, to do interval swimming. For instance, I prefer to swim fast for a couple of lengths, where I am then subsequently extremely out of breath, and to then rest for a good minute or two until I have somewhat caught my breath again, and then to swim fast again for a couple of lengths. I’ll do this for, say, about 10 intervals, which will take me between 15 to 20 minutes to complete. Therefore, does this qualify as “15 to 20 minutes” of cardio as I have previously described in no. 1 above? I am not sure because what I have just described is not a contiguous or continuous 15 minutes of running without a pause, as I originally described in no. 1 above.



4. If the answer to no. 3 above is “Yes”, then, likewise, can I employ this same thinking toward running? That is, rather than running for 15 to 20 continuous minutes at a moderate to moderately slow pace, I would, instead, run fast for a, say, ¼ mile, then rest a good minute or 2, and then run fast again for another ¼ mile. Then, after resting another minute or 2, run fast again for another ¼ mile, etc. If I were to keep up this interval training for running ¼ mile intervals (with 1 to 2 minutes of rest between each ¼ mile interval) for 15 to 20 minutes, does this then satisfy the requirement for cardio, even though it is not a contiguous or continuous 15 to 20 minutes of running without a pause?





Thank you very much for any responses.



The best to all,

Greetings!
