• "One of the most amazing concepts for sports training I've ever come across."

• "You can simulate any sports skill requiring ballistic force"

• "I bought two of then so I can do both sides simultaneously"

• "With Impulse Inertial Exercise you can isolate any muscle or muscle group and you can simulate any sports skill requiring ballistic force, that's something you can't do with a dumb bell or bar bell in any consistent manner"

*The general idea the book points out is the mathematics of what goes on with the Impulse and how those mathematics relate to what happens to the body in the real world in functional activities. It also points out how the Impulse pulls all that together and truly works with functional activities.

• "Impulse…is capable of hitting the conditioning and rehabilitation ball out of the traditional training ball park"

• "a major breakthrough in training on field power in the weight room"

• "Some of the benifits you can expect to gain from using inertial impulse training include the duplication of on-field forces, functional strength and power gains that are transferable to competition in your sport, stronger tendons and ligaments, and a reduction in training time.

• "used for training the nervous system so you can hit more effectively"

Spine in Sports, Robert G. Watkins, Chapter 32: Trunk and Lower Extremity Strenghtehing for Football, Robert Ward

• "Impulse… improving coordinated action of the trunk and legs justify its being given a high-level priority for inclusion in the training facility."

*Dr. Ward discusses quickly how the Impulse is absolutely functional in the kinds of training it does and how that function, with the Impulse, directly effects performance on the field

Eccentric Muscle Training in Sports and Orthopedics, Mark Albert, Med., PT, ATC, ChurchillLivingstone, 1991

"Versatile clinical protocols can be safely applied in a time efficient manner with minimal requirements for the trainer, therapist supervision." (point 4 on pg. 91 of the conclusion section)

*The general idea of this chapter is the Impulse can be used on all points of the body. Three case studies demonstrate that clearly you get a really good level of achievement for clinical results for various types of problems. All of these solutions are backed up with scientific research, protocols, and scientific documentation from our research equipment.

*This article documents the difference of neuromuscular affects of tonic vs. phasic techniques utilizing the Impulse

ADVANCE for Physical Therapist, "Inertial Loading Principles Added to Rehab Techniques/Equipment", Michelle P. Pronsati, August 26, 1991

"In terms of research ....what we have learned indicates that this is a very neuromuscular kind of training unit"

"Weight of more than 30lbs is used rarely with Inertial Exercise (the Impulse) he cautioned the only time I would do that is if I was training the spine and I would then use between 25lbs and 35lbs. Admittedly these are some guide lines that need additional research, but they seem to work safely & well in the clinic."

*Review of Mark Albert's presentation to the NATA. This is the first quote by somebody before any Inertial Exercise research existed. (The first quote the better of the two.)

* the statement coincides with exactly what we have been promoting for the last 22 years on this concept, that it is neuromuscular and that it builds power and works very well with backs as long as you use heavy weights

"The Inertial Machine is also an excellent means of emphasizing the total kinetic chain in sport specific movement patterns"

*They speak of it as a factual modality, to them it is just another device to train with.

"The inertial unit is an excellent exercise modality for eccentric work. By utilizing various function patterns the extremities are strengthen in an eccentric mode. Coordination and timing are additional factors that may be improved upon with this interval work out." (pg. 12)

JOSPT Volume 20, Number 5, "Muscle Torque Changes Caused by Inertial Exercise Training", Mark Albert, MEd., PT, ATC; Ellen Hillegass; Peter Spiegel, November 1994

"Inertial training appears to be a safe time effective form of clinical muscular training that can be assessed using peak torque measurements from various resistance testing. In addition the training program proved effective for muscle torque increases when compared to isokinetic training studies." (conclusion pg. 260)

*The studies show you will get greater strength gains if you train with the IET, then you will if you train with isokinetics and that is if you measure by isokinetics. It also showed that the control side gets significant strength gains even though it had no exercise what so ever. This is the first piece of scientific research evidence that indicates there is neuromuscular coordination training going on, that would be cross over.
