I was wondering. I see these long distance runners and they are mostly very skinny, and then I see these sprinters and they are very well built and cut. Why is this? Does long distance running cut back on your lean muscle tissue?
*Another Question is: If I want to build up my calves/legs, is it better to do stair climbing cardio for 10-15 min or running on the cardio machine for 10-15 min; What are the pros and cons of these two? :withstupi
there are many topics on this, use the search function... but heres some food for thought... why would a distance runner want to be big when he would have to carry all that weight for a long distance?
somewhat what I eat...
i doubt running will make your legs grow much btw
PROFILE, COMMENT PLZ
Lot's of information out there on this topic. A few of the thing's that alway's standed out to me is that; #1. Aerobic Exercise reduce's Free Testosterone level's by up to %40, #2. Any excess body weight is detrimental to a long distance runner, but a sprinter need's some mass for strength and explosion, and #3. Long Distance workout's, burn's off more muscle than sprinting. BUT, that last point is debatable.

If you want size and strength in your legs you will need to work them with weights. If you want muscular endurance, work with high reps and do some running. You should be more specific about what your goals are if you want the best advice.

Anyway, long distance runners are skinny because when you run for that long, you burn muscle and calories in general, so you'll end up very skinny and with very little fat or muscle on you. It's advantageous to the sport.
Sprinters run in short bursts so they don't burn protein for energy or burn a lot of calories, and they all lift weights to be faster/more explosive. Distance runners probably lift weights too, but most likely in the 20+ rep range because top speed/strength has about 0 effect on their race.
well long distance runners are skinny because they use up their glycomeds very fast, which leaves you drawing energy from different other sources.. i.e. fat, when there is none of this left you start burning muscle.
short distance runners burn less calories since its is a short explosion of energy.
think youve got an edge on me? think again.
When I go to the gym, I workout for about 1-1.5 hours. I just started to add running to my routine. After my workout, I head to the treadmill and run for 10 min. I currently run about 1.3 miles in 10 min. because I just started. My goal is to build more stamina but I don't want to start loosing muscle. Do you think 10 min. of fast paced running after my workouts would lead to any kind of muscle loss or just fat loss? I want to run this about 4 days a week because I like to run and it would help to further develop my calves.
