Efficient human force transmission tailored for the individual cyclist

The paper investigates the possibility of improving the efficiency of force transmission for the individual cyclist. Musculoskeletal modelling using commercial software (AnyBody) is utilised to assess variations in the bicycle configuration. Rider-specific data were collected to enable an assessment of seat position, cadence, crank arm length, and chainring shape. Optimisation of these parameters is carried out to minimise normalised muscular force, with the aim of delaying the onset of fatigue. Reductions of 13% and 18% were found in peak values. Chainring shapes were noticeably altered with significant differences between the two results due to differing musculoskeletal model fidelity.
