Intra-muscular and Inter-muscular co-ordination with wearable resistance

Intra- and intermuscular co-ordination refer to the neural factors that you can focus training on to improve force and power, whether it be for injury resistance/rehab or sporting performance. Intramuscular or within muscle factors such as motor unit recruitment, firing frequency, synchronisation and reflex activity, respond well to heavy non-specific strength training.

Intermuscular or between muscle co-ordination, refers to synergistic contribution, fixator involvement and optimising antagonist co-contraction. Schmidtbleicher (1992) believed this type of strength training needed to be “movement specific, and therefore not transferable to another movement. The specific strength training in training practice strives mainly for optimisation of intermuscular co-ordination.”  Wearable resistance is a great training tool for intermuscular co-ordination as it is a movement specific training tool you wear as part of your practice or rehab and not separate to it. For example, if you want to train change of direction in a movement specific manner, you simply strap the wearable resistance on the musculature you want to target, and begin cutting, stutter and side-stepping to your hearts content as shown in the picture. Increasing specific strength (intermuscular co-ordination) of the synergist, fixator and agonist-antagonist muscles the goal.
