Yes, I've read that about Jones and Mentzer. However, the studies I referred to do not involve going beyond momentary muscle failure while maintaining good form. I've attached a study. The recommendations, which you can find on page 49, are as follows:The low volume method has had it's proponents at least since Arthur Jones, inventor of nautilus equipment, was pushing it. It usually involves extreme intensity. More than just going to failure, but rather beyond failure with negatives and anything else you can do to push the envelope...
RECOMMENDATIONS
What is really known about the science of resistance training is contrary to the opinions expressed in the Position Stand. That is, the preponderance of research strongly suggests that gains in muscular strength, hypertrophy, power, and endurance are the result of the following simple guidelines:
• Select a mode of exercise that feels comfortable throughout the range of motion. There is very little evidence to support the superiority of free weights or machines for increasing muscular strength, hypertrophy, power, or endurance.
• Choose a repetition duration that will ensure the maintenance of consistent form throughout the set. One study showed a greater strength benefit from a shorter duration (2s/4s) and one study showed better strength gains as a result of a longer duration (10s/4s), but no study using conventional exercise equipment reports any significant difference in muscular hypertrophy, power, or endurance as a result of manipulating repetition duration.
• Choose a range of repetitions between three and 15 (e.g., 3-5, 6-8, 8-10, etc.). There is very little evidence to suggest that a specific range of repetitions (e.g., 3-5 versus 8-10) or time-under-load (e.g., 30s versus 90s) significantly impacts the increase in muscular strength, hypertrophy, power, or endurance.
• Perform one set of each exercise. The preponderance of resistance-training studies shows no difference in the gains in muscular strength, hypertrophy, power, or endurance as a result of performing a greater number of sets.
• After performing a combination of concentric and eccentric muscle actions, terminate each exercise at the point where the concentric phase of the exercise is becoming difficult, if not impossible, while maintaining good form. There is very little evidence to suggest that going beyond this level of intensity (e.g., supramaximal or accentuated eccentric muscle actions) will further enhance muscular strength, hypertrophy, power, or endurance.
• Allow enough time between exercises to perform the next exercise in proper form. There is very little evidence to suggest that different rest periods between sets or exercises will significantly affect the gains in muscular strength, hypertrophy, power, or endurance.
• Depending on individual recovery and response, choose a frequency of 2-3 times/week to stimulate each targeted muscle group. One session a week has been shown to be just as effective as 2-3 times/week for some muscle groups. There is very little evidence to suggest that training a muscle more than 2-3 times/week or that split routines will produce greater gains in muscular strength, hypertrophy, power, or endurance.
