Muscle Coordination Patterns for Efficient Cycling

Medicine & Science in Sports & Exercise, 2012
Cycling is a repetitive activity using coordinated muscle recruitment patterns to apply force to the pedals. With more muscles available for activation than required, some patterns produce high power, whereas some are more efficient. The purpose of this study was to identify relationships between muscle coordination and factors affecting muscle ...

Changes in muscle coordination with training

Journal of Applied Physiology, 2006
Three core concepts, activity-dependent coupling, the composition of muscle synergies, and Hebbian adaptation, are discussed with a view to illustrating the nature of the constraints imposed by the organization of the central nervous system on the changes in muscle coordination induced by training.

Muscle Function and Coordination of Stair Ascent

Journal of Biomechanical Engineering, 2017
Stair ascent is an activity of daily living and necessary for maintaining independence in community environments. One challenge to improving an individual's ability to ascend stairs is a limited understanding of how lower-limb muscles work in synergy to perform stair ascent.

Muscle Coordination: The Discussion Continues

Motor Control, 2000
In this response, the major criticisms of the target article are addressed. Terminology from the target article that may have caused some confusion is clarified. In particular, the tasks that have the basic features of muscle coordination, as identified in the target article, have been limited in scope.

Coordination of the leg muscles in backlift and leglift

Journal of Biomechanics, 1992
Net joint moments are often used to quantify the loading of structures (e.g. the intervertebral disc at L5S1) during lifting. This quantification method is also used to evaluate the loading of the knee, for instance, to determine the effect of backlifting as opposed to leglifting. However, the true loading of the joint as derived from net joint moments

Do Muscles Matter for Coordinated Action?

Journal of Experimental Psychology: Human Perception and Performance, 2004
This article investigates coordination stability when 2 fingers of each hand periodically tap together. The main question concerns the functional origin of the symmetry tendency, which has widely been conceived as a bias toward coactivation of homologous fingers and homologous muscular portions. In Experiment 1, the symmetry tendency was independent of

Some Mechanical Considerations on Muscle Coordination

Motor Control, 2000
This commentary emphasizes three points of discussion. (a) The terminology: The terms multifunctional, synergisic, antagonistic muscles, and synergistic and antagonistic coactivations are discussed and the conclusion is drawn that they could not be used without mentioning the particular joint motion. (b) The importance of the external joint moments for

Surface Electromyography to Study Muscle Coordination

2016
Electromyography (EMG) records the electrical activity that is generated as action potentials propagate along the length of muscle fibers. As such surface EMG is the research tool that is used in a vast majority of the works that assess muscle coordination in health and disease. Although surface EMG recordings can provide valuable information regarding

Coordination of Respiratory Muscles

1992
Coordination 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 of mediolateral balance in normal walking

Journal of Biomechanics, 2010
The aim of this study was to describe and explain how individual muscles control mediolateral balance during normal walking. Biomechanical modeling and experimental gait data were used to quantify individual muscle contributions to the mediolateral acceleration of the center of mass during the stance phase.
