Muscle adaptation

cojones

Hi,

I've searched the forum and found related topics but no specific info regarding my query.

I understand that muscle adaptation from training brings improvements, in theory. I understand that the micro tears from strength training heal to provide stronger and more efficient muscles. My question is, if you do strength training AND speed endurance (I.e. on the bike) training in the same session, what sort of adaptation takes place? Strength, endurance or a bit of both?

Any advice appreciated.

Thanks

The major adaptations from strength training are neural and muscle cross sectional area. The neural adaptations don't cross over to the bike very well, if at all.

The major adaptations from endurance training are on local enzyme systems and capillary density.

If you mean short range cycling power, then keep in mind that strength training doesn't affect the resting level of ATP or PCr concentration, nor the enzyme activity involved in anaerobic (or aerobic) energy production.

So, in essence what you will do is get better at doing both sessions on the same day, but would be better off concentrating on one or the other, depending on what it is you are seeking to improve.

Does mitochondrial density not increase with endurance training?

Thanks

Both

I do a few gym sessions and double up - though to be more effective it can be hard to really push in both sessions without overdoing it and risking an injury. Coming from a multisport background am used to doubling up training sessions as its the only way to get everything done, but the one rule I stick by is never to mix max sessions together as your just asking for trouble.

correct - that's part of the enzyme activity I'm referring too. But strength training results in mitochondrial dilution through hypertrophy.
