1. A system for monitoring and measuring exercise, comprising:

  • exercise element means defining an enclosed chamber including an opening defining a first remote pressure port defined by a first surface of said chamber, said exercise element means defining two surfaces to which force is applied during exercise;

    valve means for intake and exhaust of gas for exhausting gas from said chamber and intaking gas into said chamber to fill said chamber;

    a pressure/electrical signal transducer;

    a pressure conduit connecting said remote pressure port to said pressure/electrical signal transducer, said transducer for sensing pressure at said remote pressure port and for sensing atmospheric pressure and forming a differential signal representative of the difference between the pressure of the remote pressure port and atmosphere;

    calibration means for receiving electrical signals from said transducer means and for outputting a zero pressure signal prior to a data collection trial;

    data acquisition means for receiving said differential signal and said zero pressure signal and for outputting a digital signal representative of said differential signal, compared to said zero calibration signal.
