dc.description.abstract | This study combines metabolic and kinematic measurements at the whole-body
level, with EMG and ultrasound measurements to investigate the influence of
muscle-tendon mechanical behavior on the energy cost (Cnet) of walking (from
2 to 8 km·h−1). Belly gearing (Gb = Δmuscle-belly length/Δfascicles length) and
tendon gearing (Gt = ∆muscle-tendon unit length/∆muscle-belly length) of vastus lateralis (VL) and gastrocnemius medialis (GM) were calculated based on
ultrasound data. Pendular energy recovery (%R) was calculated based on kinematic data, whereas the cumulative activity per distance travelled (CMAPD) was
calculated for the VL, GM, tibialis anterior, and biceps femoris as the ratio between their EMG activity and walking speed. Finally, total CAMPD (CMAPDTOT)
was calculated as the sum of the CMAPD of all the investigate muscles. Cnet and
CMAPDTOT showed a U-shaped behavior with a minimum at 4.2 and 4.1 km·h−1,
respectively; while %R, VL, and GM belly gearing showed an opposite trend,
reaching a maximum (60% ± 5%, 1.1 ± 0.1 and 1.5 ± 0.1, respectively), between
4.7 and 5 km·h−1. Gt was unaffected by speed in GM (3.5 ± 0.1) and decreased
as a function of it in VL. A multiple stepwise linear regression indicated that %R
has the greatest influence on Cnet, followed by CMAPDTOT and GM belly gearing. The role of Gb on Cnet could be attributed to its role in determining muscle
work: when Gb increases, fascicles shortening decreases compared with that of
the muscle-belly, thereby reducing the energy cost of contraction. | es |
