Effects of muscle action type on corticospinal excitability and triceps surae muscle-tendon mechanics.
This study investigated whether the specific motor control strategy reported for eccentric muscle actions is dependent on muscle mechanical behavior. Motor evoked potentials, Hoffman reflex (H-reflex), fascicle length, pennation angle, and fascicle velocity of soleus muscle were compared between isometric and two eccentric conditions. Ten volunteers performed maximal plantarflexion trials in is...
متن کاملEarly neuromechanical outcomes of the triceps surae muscle-tendon after an Achilles' tendon repair.
OBJECTIVES To compare the neuromechanical and functional characteristics of the legs of athletes who underwent unilateral Achilles' tendon repair and their controls, and to determine any correlation between the characteristics. DESIGN A case-control and cross-sectional study. SETTING A university institute. PARTICIPANTS Male athletes (N=33) were recruited; 23 in the ≥3- and <12-month post...
متن کاملAge-related differences in Achilles tendon properties and triceps surae muscle architecture in vivo.
This study examined the concurrent age-related differences in muscle and tendon structure and properties. Achilles tendon morphology and mechanical properties and triceps surae muscle architecture were measured from 100 subjects [33 young (24 ± 2 yr) and 67 old (75 ± 3 yr)]. Motion analysis-assisted ultrasonography was used to determine tendon stiffness, Young's modulus, and hysteresis during i...
متن کاملElectromyographic Analysis of the Triceps Surae Muscle Complex During Achilles Tendon Rehabilitation Program Exercises
BACKGROUND Specific guidelines for therapeutic exercises following an Achilles tendon repair are lacking. HYPOTHESIS A hierarchical progression of triceps surae exercises can be determined on the basis of electromyographic (EMG) activity. STUDY DESIGN Randomized laboratory trial. METHODS Bipolar surface electrodes were applied over the medial and lateral heads of the gastrocnemius as well...
متن کاملMechanics of human triceps surae muscle in walking, running and jumping.
Length changes of the muscle-tendon complex (MTC) during activity are in part the result of length changes of the active muscle fibres, the contractile component (CC), and also in part the result of stretch of elastic structures [series-elastic component (SEC)]. We used a force platform and kinematic measurements to determine force and length of the human calf muscle during walking, running and...
