For those who may be interested, the original definition of the term "DCER"
as yet another unsatisfactory replacement for "isotonic" appears to derive
from Fleck & Kraemer's book on strength training:
<<DYNAMIC CONSTANT EXTERNAL RESISTANCE TRAINING
A more workable term for resistance training exercise in which the external
resistance or weight does not change and both a lifting (concentric) and a
lowering (eccentric) phase occur during each repetition is dynamic constant
external resistance (DCER) training. DCER implies that the weight or
resistance being lifted is constant and held constant. Thus, DCER better
describes this type of resistance training better than the old term isotonic.
