Effects of a Non-Circular Chainring on Sprint Performance During a Cycle Ergometer Test
Autor: Frédérique Hintzy, Frédéric Grappe, Alain Belli
Publikováno v: Journal of Sports Science and Medicine, Vol 15, Iss 2, Pp 223-228 (2016)
Non-circular chainrings have been reported to alter the crank angular velocity profile over a pedal revolution so that more time is spent in the effective power phase. The purpose of this study was to determine whether sprint cycling performance coul

EMG Activity does not Change During a Time Trial in Competitive Cyclists
Autor: Sébastien Duc, Frédéric Grappe, Andrew C. Betik
Publikováno v: International Journal of Sports Medicine
International Journal of Sports Medicine, Thieme Publishing, 2005, 26 (2), pp.145-150. ⟨10.1055/s-2004-817922⟩
The purpose of the present study was to measure the electromyographic (EMG) activity of four lower limb muscles and the propulsive torque during a cycling time-trial (TT). Nine competitive cyclists (V.O (2max): 73.8 +/- 5.3 ml . min (-1) . kg (-1)) p
