This
system includes a self-contained, non-invasive
system for collecting work and
power performance data on nearly any kind of repetitive-motion exercise. See the glossary for definitions of terms used in this specification. It is non-invasive in that no permanent modifications need made to existing
exercise equipment. It is a battery-powered
system that remotely senses iterations of a moving part or body member, and records them with a time-stamp. It also records weight and distance of travel if they are input-but for some exercises this function may be deemed not necessary, or ignored. If time, weight, and distance are known then work and power
metrics can be calculated on the data when it is analyzed on a host computer. This data can then be graphed to provide comparisons from workout session to workout session. The user can detect trends, and differences in performance as workout variables are manipulated. Workout variables include, but are not limited to: weight, distance of travel, time, order of exercise stations, number of sets, number of repetitions per set, pattern of weight increase / decrease for a given exercise
station over the sets, pattern of extension and contraction per repetition, etc.
