However, less is known how the muscle synergy
is affected, if the selected muscle group is strengthened.
The nature of muscle synergy in task planning and execution may help to elucidate the question of how to activate a group of relevant muscles to best achieve stroke rehabilitation.
Control of reaching movements by muscle synergy combinations.
Muscle synergy is defined as a specific and consistent spatiotemporal pattern of muscle activations that leads to similar joint trajectories (Ting and McKay, 2007) and have been proposed as a neural strategy for simplifying the neuromuscular control.
Muscle synergy is particularly important in rowing because as a power-endurance sport that recruits 70% of total muscle mass (Steinacker et al.
There is no a-priori power analysis test for PCA analysis, however, based on previous studies of muscle synergy (Hug et al.
Principal Component Analysis (PCA) was applied to extract the muscle synergy as suggested by Ivanenko et al (2004).
At B-level muscle synergy controls the two-dimensional joint bend and has to synchronize the action of at least two muscles: extensor and flexor.
Summing up, A-level may be associated with one-dimensional muscle contraction and time perception "now-not now"; B-level--with two-dimensional muscle synergy and time perception "flexor first-extensor later"; C-level--with three-dimensional agility and/or dexterity and time perception at the level of object permanence (i.
They are (This is sometimes described as designed to fatigue one element of "supersets") a muscle synergy
prior to performing more resistance training on the whole movement pattern.
While more feasible, achieving simultaneous, independent control using intramuscular EMG is still a challenging task, because a stable muscle synergy map must be developed for each user.
