Muscle Coordination while Pulling up During Cycling
International Journal of Sports Medicine, 2010The aim of this study was to determine the influence of the pull up action on the pedalling mechanics and muscle coordination during cycling. 9 elite cyclists pedalled at 320 watts with their preferred technique and while pulling up. The pull up action increased significantly the pedalling effectiveness during the upstroke and around the bottom dead ...

Muscle coordination changes during intermittent cycling sprints
Neuroscience Letters, 2005Maximal muscle power is reported to decrease during explosive cyclical exercises owing to metabolic disturbances, muscle damage, and adjustments in the efferent neural command. The aim of the present study was to analyze the influence of inter-muscle coordination in fatigue occurrence during 10 intermittent 6-s cycling sprints, with 30-s recovery ...

Analysis of muscle coordination strategies in cycling
IEEE Transactions on Rehabilitation Engineering, 2000The functional significance of the stereotypical muscle activation patterns used in skilled multi-joint tasks is not well understood. Optimization methods could provide insight into the functional significance of muscle coordination. The purpose of this study was to predict muscle force patterns during cycling by pushing and pulling the pedal using ...

Oral and laryngeal muscle coordination during swallowing
The Laryngoscope, 1994AbstractThe objective of this experiment was to determine the relative contributions and patterns of activity of different muscles involved during the oral phase of swallowing. Electromyographic (EMG) signals were recorded from the orbicularis oris inferior, masseter, palatal elevator, anterior and posterior genioglossus, mylohyoid, anterior belly of ...

Coordination of leg muscles during speed skating
Journal of Biomechanics, 1991Five speed skaters of elite performance level and six speed skaters of trained level were subjected to an inverse dynamical analysis during speed skating. Push-off forces were registered by means of special skates. Myoelectric activity (EMG) of ten leg muscles and cinematographic data were recorded.

Coordination of Respiratory Muscles
1992Coordination of respiratory muscles is an important feature of normal breathing, and it may be critical for survival in subjects with disease of the lungs or chest wall. For simplicity, we sometimes think of inspiratory and expiratory muscles as single units, and we speak of inspiratory drive and expiratory drive as if they were single variables that ...

Muscle coordination and function during cutting movements
Medicine & Science in Sports & Exercise, 1999The objectives of this study were to: 1) establish a database of kinematic and EMG data during cutting movements, 2) describe normal muscle function and coordination of 12 lower extremity muscles during cutting movements susceptible to ankle sprains, and 3) identify potential muscle coordination deficiencies that may lead to ankle sprain injuries ...

Multi-muscle coordination during a challenging stance
European Journal of Applied Physiology, 2015This study aimed to identify the muscle synergies during standing under various sensory contexts in healthy young adults.Sixteen healthy young adults participated in this study. The 4-min stance task was conducted under vision (eyes open or eyes closed) and proprioception (standing on ground or narrowed blocks) manipulated contexts.

Journal of Electromyography and Kinesiology, 2007
The aim of the present study was to determine how the intra-muscular segments of three shoulder muscles were coordinated to produce isometric force impulses around the shoulder joint and how muscle segment coordination was influenced by changes in movement direction, mechanical line of action and moment arm (ma). Twenty male subjects (mean age 22 years;
