However, further studies are needed to judge reliability.
Introduction Maximal anaerobic power can be measured on friction-loaded cycle ergometers or isokinetic ergometers. Many protocols have been proposed for maximal power measurement: On friction-loaded ergometer, maximal power corresponds to power at peak velocity or is computed during the acceleration phase taking into account the power necessary to increase the flywheel kinetic energy [ 10 ].
The relationship between pedal rate and braking force or torque can be described by a linear relationship [ 35 — 911 ]. Linear force-velocity relationships have been described for all-out exercises performed on a cycle ergometer not only with the legs i.
The individual characteristics of the force-velocity or torque-velocity relationship can be defined by two parameters: Maximal power corresponds to an optimal pedal rate equal to and an optimal load or torque equal to or. Previous studies reported that [ 8 ] or peak power during a Wingate test [ 12 — 15 ] are significantly correlated with the percentage of the fast muscle fibers in the vastus lateralis.ForceVelocity
Furthermore, a significant positive correlation was observed between and triceps surae musculotendinous stiffness at relative peak torque corresponding to the optimal cycling rate [ 16 ]. On the other hand, the value of during sprint cycling was significantly correlated with vastus lateralis myosin heavy chain II composition in a study comparing old and young participants [ 17 ].

The proportion of fast twitch fibres expressed in terms of cross-sectional area was highly correlated with[ 18 ], and the authors of this latter study suggested that would be the most accurate parameter to explore the fibre composition of the knee extensor muscle from cycling tests. The value of in cycling depends on the strength and the rate of force development of muscle knee extensors [ 19 ].
The Wingate optimal braking force can also be determined from the result of a cycling force-velocity test as this braking force is close to Therefore, it could be interesting to determine the parameters of the force-velocity relationships, or in addition to on a cycle ergometer. A post shared by Chris Beardsley chrisabeardsley on Feb 8, at This might be achieved by high-velocity strength training.

Training with different types of external load could therefore be useful for emphasizing different ends of the force velocity curve. Using constant resistance or variable resistance could be helpful for improving force at higher velocities.
