differences in metabolism of runners/lifters?

[SPAM]

Something i've been pondering for awhile now. What is the difference in metabolism patterns, meaning digestion speed and nutrition utilization throughout each day, of runners and weightlifters assuming they both get between 30 to an hour of their respective activity most days of the week?

Anyone have any thoughts?

come on, someones gotta have something.

Distance runners, especially those who train for at least a 10k have higher metabolism than a typical bodybuilder. Your body will demand a lot of calories when you're doing 50+ miles a week.

depends what kind of runners..sprinters appear always ripped because they have such a fast metabolism from spriting, distance runners metabolism is realitivly the same, however it stays elevated much long being they are doing distance. for a bodybuilder, everything is different, the more mass you have, the more calories your muscles burn, therefore theoretically their metabolism is more like a sprinter, just not as extreme or else all bodyduilders would be ripped lol

Distance runners will, in general, have a higher proportion of slow twitch muscle fibres, especially in areas like the quadriceps. This means that distance runners are able to oxidize fats much more effectively than body builders. The amount of cardio will also increase metabolism and amount of calories burnt.

Weight lifters however have a larger density and volume of short twitch muscles, and muscle mass in general. Meaning higher caloric requirements.

From what I know distance runners would more effectively utilize their food as most of it would not be needed to replenish glycogen stores after their workout, but instead it would be converted more into fat which would be more effectively burnt afterwards.

Weight lifters would require more strict eating schedules (I'm not entirely sure of this of course), in particular pre, during and post workout, in order to replenish glycogen stores. Think of a weightlifters muscle as a one time battery, intended to lift a huge load in a short amount of time, after which it needs to be refueled so it can grow and be re-used. In contrast is the distance runners slow twitch muscles, which are designed to carry the runner very far and require nutrition to fuel them but not in order to necessitate large volume growth.

Thanks for the responses guys. I've got another off-topic question, if you wouldn't mind.

Is it normal to feel drained when running the day after a personally unusually long run? I did 40 minutes of running yesterday while, three times a week, i would go just as fast for only 25-30 minutes. When I went for a two-mile run today, I felt more challenged than I did before te big run yesterday. How can i counterract this?

Thanks.
