The third system being the Aerobic Oxidative System which consists primarily of exercises that are performed at an intensity lower than
that of the anaerobic threshold (3).
This average reading gives you a very accurate estimation
of your anaerobic threshold.

of Anaerobic Threshold Training (AT2).

Exercise that consists
of two minutes
of rapid walking followed by a twenty or thirty - second burst
of running up and down a flight
of stairs (or similar activity) that gets your heart rate up past your
anaerobic threshold repeated a total
of three to five times is all you need to promote a burst
of growth hormone secretion.
In other words, it doesn't tell you anything about your health, only vaguely points at your
anaerobic threshold (with a series
of other calculations) and doesn't consider your aerobic development at all.
Exercise performed at the
anaerobic threshold causes prominent changes in hormone values, and they continued to rise up to 90 %
of max heart rate [2].
I would say that most / all would not reference training specific muscles fibers as the reason for doing those workouts — likely it would be explained in terms
of VO2max, lactate
threshold, running economy, aerobic, and
anaerobic.
If you are at your
anaerobic threshold, you are using all
of your Type I fibers and most
of your Type IIa fibers.
The running world pays a lot
of attention to aerobic and
anaerobic physiology, using terms like VO2max, aerobic
threshold, lactate
threshold, aerobic base, and max heart rate.
Doing so also seems to gradually raise your
anaerobic threshold, sparing glycogen and allowing higher degrees
of intensity to be performed in an aerobic state.
Attia went from burning 95 percent carbohydrate calories at
anaerobic threshold to burning 25 percent carbs and 75 percent fat at the same
threshold heart rate after a devoted period
of dietary transformation.
Anaerobic metabolism produces energy for short, high - intensity bursts
of activity lasting no more than several minutes before the lactic acid build - up reach a
threshold known as the lactate
threshold and muscle pain, burning and fatigue make it difficult to maintain such intensity.
The MAF HR points to a physiological
threshold of the body, called the aerobic
threshold (the
anaerobic threshold usually occurs 30 - 40 BPM higher).
VO2 max is driven to its genetic ceiling, and
anaerobic threshold is optimized so work can be sustained at a higher level
of oxygen consumption.
Anaerobic threshold is usually marked by a specific heart rate and represents the limits
of the aerobic energy system.
That said, let's say that it turns out that the 180 - Formula does predict your aerobic
threshold relatively closely, and that you've been doing the bulk
of your training at
anaerobic intensities.
A lot
of elite marathoners, for example, run something like back - to - back 5 miles between their aerobic and
anaerobic thresholds (with 2 mile jog in between).
Though it was a sweaty challenge, I didn't push myself to my out -
of - breath
anaerobic threshold.
Interval workouts can be sophisticated and structured specifically for an athlete based upon
anaerobic threshold testing (AT) or they can be casual, unstructured bursts
of speed added to any workout as the athlete desires.
I do 90 minute sessions at about 3 % below aerobic /
anaerobic threshold (avg ~ 85 %
of MHR for me, but everyone is different).
Not only that, studies have also shown that creatine also improves your
anaerobic threshold, delaying the onset
of lactic acid forming in the muscles.
