Does cheating pay: the role of externally supplied momentum on muscular force in resistance exercise.
Arandjelović O.
Abstract
Our work investigates the use of "external momentum" in the context of hypertrophy-oriented training. This is momentum supplied to the load (such as a dumbbell) used in an exercise by means of action of muscles not inherently involved in the exercise. We challenge the general consensus that the use of such momentum often described as "cheating" is counterproductive. We focus on the use of external momentum in the shoulder lateral raise and adopt a framework whereby exercise execution is simulated on a computer. This is achieved using a physical model of motion which is combined with anthropomorphic measurements and empirical data of muscular recruitment from previous work. The introduction of moderate momentum (producing initial angular velocities around 57.5° s(-1)) increases the torque of the target muscles even without an increase in the load used. A moderate increase in the load and the use of momentum allows the torque to be increased even further. In contrast, excessive use of momentum results in lower demands on the target muscles, while an excessive increase of the load reduces the total hypertrophy stimulus by virtue of the decreased number of repetitions which can be performed successfully and thus the dramatically shortened time under tension. Our results disprove the conventional belief that the use of external momentum necessarily reduces the overload of the target muscles. A moderate use of external momentum increases both the per-repetition peak torque and the total hypertrophy stimulus in a set.

Arthur Jones already said this back in '70-71

It seems every guy is training expert but they can't explain why they look like shit when they don't use drugs for 6 months. I also take exception with the gym resident expert that is a skinny kid with a couple of years training under his belt giving advice. The last expert is the 20 something guy or girl with a one week personal training certificate that now thinks they know everything about training. I would listen to a drug free in shape guy in his 50's who has trained his whole life than any of the above.
