At what point does anearobic work impede on aerobic development

Are you racing anytime soon?.

Where do you flush your lactate? I am aware of people sweating, salivating and even urinating and defecating while running but I've never seen someone flushing anything.

Except perhaps getting a flushed complexion.

I suppose if someone told you to be as gentle as a dove you would try to lay an egg.

I think keeping some speed year round is a good idea otherwise the detraining can be significant. I think 10x400 might be more than you need. You might even alternate weeks of Vo2max workout and LT workout just to maintain them.

I did a lit review many years back and anaerobic work capacity peaked after 3-6 weeks of work--the variation was due to differing workouts and probably the capabilities of the athletes (cyclists and runners).

When you do it too frequently or concurrently with too much aerobic work to allow adequate recovery.

Somebody should say it wrote:

Dove's are not gentle. That's a myth, just like flushing lactate.

Maybe I am out of date but all of the research that I have read states that when aerobic and anaerobic training are performed concurrently that the anaerobic development is impeded rather than the other way around.

I guess that if the anaerobic work isn't tiring you out, injuring you, taking away from your aerobic training, or is not done too close to a race day that you should be fine?

Any ExPhys gurus want to chime in on this one?

Something like 10x400m at 5K pace (75 secs), with 200m jogging recoveries, once per week, is probably OK on both counts.

Lydiard didn't approve of aerobic intervals which are the staple of pretty much every modern program.

when you cut your steady 10 miler to an easy 5 so you feel fresh for your planned interval workout the next day.

but seriously, IMO the workout you'd like to add is similar Daniels R pace work. it's meant to help you biomechanically, not be an anearobic gut-busting session leaving you keeled over in the infield. you'll benefit by feeling more comfortable at those paces + be more economical at slower paces.

200-400s at 800-to-mile pace with COMPLETE recovery (meaning 'however long it takes for you to be ready to run the next rep as fast and as comfortably as the last'....the little bit of lactate that does start to build gets cleared during the jog recovery) can be done year-round. hell i'm training for a HM right now and once a week i throw on the spike snd do 4-6 200s/300s at somewhere between 800 and mile pace with full recovery. helps me feel 'snappy' and keep some pop in my legs with all the threshold work + mileage i'm doing. and when track season rolls around, running that fast won't seem foreign.

i think lydiard is talking about 'going-to-the-well' type interval/anaroebic work...like 400s or 600s with VERY short rest, the tying-up-and-then-barfing-type stuff. stay away, only go there 2-3 times a year.
