Here it is in a nutshell.
"fact" (Feldman and Chlebek Test (opens in new tab)) is an exciting new method for testing and training in any
endurance sport. "fact" is the product of six years of practical research in
the field. The basis of the system is a Heart Rate - Lactate test to
establish heart rates used for training and racing. A sample test data
printout is shown below. The Lactate vs Heart Rate curve (red)
establishes the heart rate for the Lactate Balance Point (lowest point on
the curve) and the line of Heart Rate vs Speed (blue) is used to monitor the
progress the athlete makes as a result of training. The Lactate Balance
Point heart rate is a dynamic value that changes with training and racing.
As a result the blood lactate of an athlete must be continually monitored to
prevent over-training (or in some cases, training at too low an intensity level
for effective adaptation). Lactate Balance Point determined by the fact test protocol
is a true steady state for heart rate, lactate and performance. This
heart rate is crucial information for determining the most efficient training
Now remember, your lactate threshold is not an actual event. It was a concept developed by studies done on 16 elite runners. And just like LT (Lactate Threshold), this Lactate Balance Point does not represent an actual metabolic event.
So I guess the question is....What IS the point? Let me know when you find it.
