PURPOSE: To demonstrate the applicability of the power balance model to elite
handcycling and to obtain values for gross efficiency (GE). METHODS: Four members
of the Dutch Paralympic team performed trials on a 250-m indoor track. Velocity
(v) and power output (PO) were measured in conjunction with physiological
measures to obtain values for GE. The data were used to construct and validate a
power balance model of handcycling. RESULTS: The empirically derived relationship
between PO and velocity was: PO = 0.20v(3) + 2.90v (R(2)= 0.95). Mean GE during
submaximal performance was 17.9% +/- 1.6%. CONCLUSION: Handcycling performance
can successfully be modelled with a power balance model. The model provides
insight into the magnitude of power production and dissipation during elite
handcycling. Handcycling is a relatively efficient upper body mode of propulsion
with associated high metabolic demand at race velocities.
