Abstract
Methods and apparatus for determining the effective force generated by an athlete acting upon a rowing apparatus are disclosed. A flexural member attached to the rowing apparatus and a footboard hingably attached to the flexural member at its upper end and slidably attached to the rowing apparatus at its lower end are provided. The flexural member is fitted with strain gauges which produce a signal indicative of the strain in the flexural member, this signal can then be converted to a measure of the effective force applied to the oars. Most preferably, apparatus of the present invention substantially eliminates the effects of residual torque friction, thermal deformation and the like by isolating the flexural member from which strain data is taken.
