The below may be of relevant:

On a more serious note, I was filing away some of my senior physical
therapy students' projects a few weeks ago and came across a study  that they 
did for me on muscle hypertrophy in response to electrical
stimulation (ES) of different durations.  We found that 4 months of fairly 
intense ES of duration 3 seconds per repetition (20 stimulations spread over 
about 5 minutes per muscle group, with at least 15 seconds rest between 
stimulations) produced a statistically significant average increase in 
quadriceps circumference of 7% among fairly experienced weights users (minimum 
of one year's regular gym usage).  In other words, very brief, intense muscle 
contractions with a time under tension (TUT) of less than 3 seconds per rep 
managed to produce significant hypertrophy.

Our finding is by no means an isolated one, since similar research in various 
physical therapy and physiotherapy journals has noted that  muscle hypertrophy 
may be produced by very brief TUTs. I wonder if those who religiously proclaim 
the use of much longer TUTs are aware of this research?
