ECCENTRIC CYCLE TRAINING Elevates the quadriceps strength and volume

Eccentric cycle ergometry: An old concept turned into a novel training modality Stéphane P. Dufour, PhD | Faculty of Sport Sciences, University of Strasbourg, France In concentric (CON) muscle work, the muscle shortens during activation and exerts motor actions, whereas in eccentric (ECC) muscle work, the muscle undergoes a forced lengthening while bearing an external load and exerts braking actions. The last 15 years have seen a renewed interest for ECC cycle ergometry. The very first ECC cycle ergometer for the lower limbs was described by Abbott et al.1, 2 (Fig. 1) and was subsequently...

The lower oxygen cost of ECC cycling might be due to a combination of non-adenosine triphosphate (ATP)dependent “mechanical” rupture of the actin-myosin crossbridges 15, 16, greater distance covered by each individual actin-myosin crossbridge17, 18 and lower recruitment of motor units. Therefore, the general feeling of subjects cycling eccentrically is that exercise is much easier compared to the CON cycling, as attested by lower levels of perceived exertion. Also of particular interest are several reports which suggest that despite being “energy efficient”, ECC cycling might increase...

2. Eccentric cycle exercise do not necessarily generate muscle damage ECC muscle work can lead to marked exercise-induced muscle damage (EIMD), especially when high muscle forces are generated22-24 and/or if the ECC muscle actions are performed at high velocity25 or short muscle length.26 However, the magnitude of EIMD is progressively reduced after repetition of the same ECC exercise; (i.e repeated bout effect)22, 24, 27 and subjects engaged in regular ECC training become less susceptible to EIMD28-30. Therefore, if ECC cycling intensity is increased gradually, both young31, 32 and older33,...
