So, over time I should be able to run faster, longer and still maintain that heart rate? so if I use this formula for max training heart rate – 180 -45 (my age) + 5 (for athletic history) I get 140.

A point on efficiency and heat loss, which I think I saw you mention in another post. I don't think 25% efficiency means that 75% is lost to heat, I think it means that of oxygen consumed (measured in W), you can get 25 W of power output for a given task (i.e. cycling). The other 75W does not all go to heat, but may go to movement of the body segments (acceleration / deceleration). Thus some of the energy may actually be used for "internal work".

Jump rope is great exercise. What could possibly be wrong with it? If you've peaked you can always go longer, if not harder. Great article and comments!

Jump rope is great exercise.
What could possibly be wrong with it?
If you’ve peaked you can always go longer, if not harder.

I've used jump rope for over 7 years for interval and steady state cardio. In the techncal sense,..I've mastered it,no more rope catches to speak of. I can do continuos double unders until i puke, ..mixing in triple unders if I really wanna push myself.(and my joints). I haven't heard you mention much about jump rope before,..is it as good as swimming or jogging/cycling in your educated opnion? It's just so much more fun than other types of cardio so I'm king of biased. I won't mention which gura first got me hooked on it but he's the wrestler/ex marine. ok ok ok, what about jump rope?

That`s because when you run, he explained, your HR only reaches 150bpm at most. Seriously, my first thought was just "can`t they go faster"? Then again if they are already running like madmen and can maintain those HR`s then endurance athletes have it all wrong and should convert to circuit training and HIIT.

But even in the case where economy/technique improves, which can reduce caloric expenditure at a given submaximal level, that doesn't change the fact that the person can simply work at a higher intensity to burn more calories. That is, the swimmer with the better technique can swim FASTER at teh same submaximal level (due to improvements in economy) so I still think that the argument that 'Cardio sucks because you get more efficient' fails. You simply are able to work harder (and hence burn more calories) as that occurs. thanks for the comment Lyle Don’t disagree although I think swimming, because it’s so damn technical, tends to be sort of a special case.

While your exercise efficiency might not improve much, I guarantee that economy will improve drastically... so yes, if you're feeling that you don't burn as many calories in running a mile, that is probably true due to an increase in exercise economy. I think designing your workouts based on elapsed time and target heart rate is much more effective sustain a *challenge* to your fitness one thing that you cannot discount is the improvement in work economy. for example, a novice swimmer or runner might burn a lot more calories than someone with even a little training, simply due to stroke or balance.

I'll reconsider before I spout it again.
