Influence of Cervical Muscle Fatigue on Musculo-Tendinous Stiffness of the Head-Neck Segment during Cervical Flexion
AIM The aim of this study is to determine if the fatigue of cervical muscles has a significant influence on the head-neck segment musculo-tendinous stiffness. METHODS Ten men (aged 21.2 ± 1.9 years) performed four quick-release trials of flexion at 30 and 50% MVC before and after the induction of muscular fatigue on cervical flexors. Electromyographic activity was recorded on the sternocleido...
متن کاملInfluence of 90-day simulated microgravity on human tendon mechanical properties and the effect of resistive countermeasures.
While microgravity exposure is known to cause deterioration of skeletal muscle performance, little is known regarding its effect on tendon structure and function. Hence, the aims of this study were to investigate the effects of simulated microgravity on the mechanical properties of human tendon and to assess the effectiveness of resistive countermeasures in preventing any detrimental effects. E...
متن کاملSkeletal Muscle Fiber Type: Influence on Contractile and Metabolic Properties
Skeletal muscle demonstrates a remarkable plasticity, adapting to a variety of external stimuli (Booth and Thomason 1991; Chibalin et al. 2000; Hawley 2002; Flûck and Hoppeler 2003), including habitual level of contractile activity (e.g., endurance exercise training), loading state (e.g., resistance exercise training), substrate availability (e.g., macronutrient supply), and the prevailing envi...
متن کاملMusculo-tendinous stiffness of the head-neck segment for extension movement during application of quick-releases
Since head-neck segment stabilization is critical for human safety and balance control, the aim of this study was to investigate changes in musculo-tendinous stiffness of the head-neck segment during different tasks. We propose to consider the head-neck segment as a singlejoint system with a changeable geometry as proposed in [1]. The aim was to evaluate the musculo-tendinous stiffness for head...
متن کاملMyosin isoforms in anuran skeletal muscle: their influence on contractile properties and in vivo muscle function.
Functional studies on isolated single anuran skeletal muscle cells represent classic experiments from which much of our understanding of muscle contraction mechanisms have been derived. Because of their superb mechanical stability when isolated, single anuran fibers provide a uniquely powerful model system that can be exploited to understand the relationship between myosin heavy chain (MHC) and...
