Shortening behavior of the different components of muscle-tendon unit during isokinetic plantar flexions.
The torque-velocity relationship has been widely considered as reflecting the mechanical properties of the contractile apparatus, and the influence of tendinous tissues on this relationship obtained during in vivo experiments remains to be determined. This study describes the pattern of shortening of various muscle-tendon unit elements of the triceps surae at different constant angular velociti...
متن کاملThe effect of plantar flexor muscle fatigue on postural control.
OBJECTIVE Previous studies have demonstrated that ankle muscle fatigue alters postural sway. Our aim was to better understand postural control mechanisms during upright stance following plantar flexor fatigue. METHOD Ten healthy young volunteers, 25.7±2.2 years old, were recruited. Foot center-of-pressure (CoP) displacement data were collected during narrow base upright stance and eyes closed...
متن کاملThe role of ankle plantar flexor muscle work during walking.
Impaired ankle plantar flexor (APF) function is a frequent cause of gait limitations, but the role of the APF in the forward propulsion of the body remains controversial. To better understand both the direct and indirect effects of the APF during push-off and through advancement of the leg, mechanical work and inverse dynamic analyses were performed on 8 normal subjects during level walking. Du...
متن کاملPassive stiffness of the ankle and plantar flexor muscle performance after Achilles tendon repair: a cross-sectional study
BACKGROUND Deficits in ankle muscle strength and ankle stiffness may be present in those subjects who underwent surgical treatment for an Achilles tendon rupture. The presence of these long-term deficits may contribute to a lower performance during daily activities and may be linked to future injuries. OBJECTIVE To compare the ankle passive stiffness and the plantar flexor muscle performance ...
متن کاملThe role of human ankle plantar flexor muscle-tendon interaction and architecture in maximal vertical jumping examined in vivo.
Humans utilise elastic tendons of lower limb muscles to store and return energy during walking, running and jumping. Anuran and insect species use skeletal structures and/or dynamics in conjunction with similarly compliant structures to amplify muscle power output during jumping. We sought to examine whether human jumpers use similar mechanisms to aid elastic energy usage in the plantar flexor ...
