Influence of Position and Power Output on Upper Limb Kinetics in Cycling
Autor: Antony Costes, Pierre Moretto, David Villeger, Bruno Watier, Nicolas A. Turpin
Publikováno v: Journal of Applied Biomechanics. 32:140-149
Several suggestions on the upper limb involvement in cycling exist but, to date, no study has quantified upper limb kinetics in this task. The aim of this study was to determine how crank power and pedaling position (seated or standing) affect upper

The aims of this study were to determine if isolated maximum joint torques and joint torques during a maximum polyarticular task (i.e. cycling at maximum power) are correlated despite joint angle and velocity discrepancies, and to assess if an isolat

International audience; When a high power output is required in cycling, a spontaneous transition by the cyclist from a seated to a standing position generally occurs. In this study, by varying the cadence and cyclist bodyweight, we tested whether th

Can muscle coordination explain the advantage of using the standing position during intense cycling?
Autor: Pierre Moretto, Nicolas A. Turpin, Antony Costes, Bruno Watier
Publikováno v: Journal of science and medicine in sport. 20(6)
When compared to seated, the standing position allows the production of higher power outputs during intense cycling. We hypothesized that muscle coordination could explain this advantage. To test this hypothesis, we assessed muscle activity over a wi

Elastic energy in locomotion: Spring-mass vs. poly-articulated models
Autor: Pierre Moretto, Bruno Watier, Antony Costes, David Villeger
Publikováno v: Gaitposture. 48
The human is often modeled as a Poly-Articulated Model (PAM) with rigid segments while some authors use a Spring Mass Model (SMM) for modeling locomotion. These two models are considered independent, and the objective of this study was to link them i
