Colorado Experiment

The Colorado Experiment Muscle Gain

The time May, 1973. The place Colorado State University. The equipment Nautilus. Person conducting the experiment the legendary Arthur Jones.

Jones made six contentions about training related to the Colorado Experiment which he stated in Iron Man Magazine:

Jones contended that the growth of human muscular tissue is related to the intensity of exercise; increases in strength and muscle-mass are rapidly produced by very brief and infrequent training ... if the intensity of exercise is high enough.

He also had a contention that too much training was undesirable, that the negative aspect of lifting is one of the most important factors, that no special diet is necessary as long as a well-balanced diet is used, that the use of steroids is not necessary or desirable, and that maximum gains in muscle mass and body strength via the employment of full range, rotary form, automatically variable direct resistance.

The end results of the experiment were that Casey Viator gained a mind boggling 63 pounds in the month (a gain of 45 pounds of muscle and a loss of 18 pounds of fat) spent on the experiment. Arthur Jones himself was also a subject for the experiment, and he gained 15 pounds in three weeks (a gain of 13 pounds of muscle combined with a loss of 2 pounds of fat).

There was some controversy with the results in that Viator had lost 30 pounds prior to the experiment from an illness and many point to the factor of muscle memory, the ability of the body to bounce back to a former muscular state quicker than someone who had never been there before.

It has also been pointed out that the results have never been repeated in a research or scientific study. The Colorado Experiment has taken on a legendary status and is part of the history of HIT.
