Hi there.
You are correct when you say that using reps and sets and load provides a
gross measurement of volume and intensity of work.

I would recommend a good quality displacement transducer that can be
connected to a bar. This will give access to the magnitude and rate of
displacement ie information such as the vertical height through which a load
is moved, the rate at which the bar travels and give the researcher the
ability to separate concentric and eccentric phases. This will allow the
researcher to access data specific to the athlete.

There are several systems out there but be carefull as some do not give
access to the raw data ie displacement with time and only give the
researcher access to some calculated values. The FitroDyne System is one of
these systems. It is good enough and will give some of the basic information
but having access to the displacement data collected at an adequate sample
frequency is essential if the researcher is to be able to manipulate the
data in a way specific to the research.

Most displacement transducers can be easily connected to PC's or Mac's
through USB ports and the raw data can be easily manipulted in software such
as Microsoft Excel or Matlab or LabView etc.

Hope this helps.

Cheers

Gareth Gilbert
