“…However, in welltrained cyclists the influence of road gradient (RG) on FCC has not been extensively investigated in order to provide a description of the relationship between these two variables. Among the biomechanical factors potentially affecting FCC, the influence of crank inertial load (CIL), the effect of which counteracts the changes in crank angular speed, was investigated, and results have been controversial (Bertucci et al, 2007;Duc et al, 2005;Fregly and Zajac, 1996;Hansen et al, 2002a, b;Lollgen et al, 1975;Mognoni and di Prampero, 2003;Patterson et al, 1983;Voigt and von Kiparski, 1989). Hansen et al (2002b) studied nine healthy males riding on a treadmill and observed that in some situations CIL can influence FCC to the same extent as power output.…”
