• EMG can be measured non-invasively with special electrodes placed on the skin overlying the muscle(s) of interest (i.e. surface EMG, sEMG)
• sEMG technology has enabled the use of sEMG signal for medical and sports physiology related muscle performance analysis
• Activation level of the muscle
• Activation levels of specific types of muscle cells
• Muscle fatigue
• Timing of muscle activation(s) in relation to movement
For good training results, it is important to know that the training activates the right muscles to proper activation level. Mpower measures your muscle’s sEMG signal and shows the activation level.
Fast muscle cells are essential for speed, explosive and maximum power production. They also grow more effectively in size but are harder to activate. Slow muscle cell activation is required for endurance training and control of posture and coordination. With Mpower you can measure and monitor online the activation levels of each type of muscle cells and adjust your exercise according to the type and level of desired workout.
Sometimes one side of the body may develop to be stronger than the other. In such cases Mpower helps you to identify the imbalance and monitor your training to ensure the proper development of the weaker side.
For effective training it is beneficial to see muscle fatigue start to develop and how far it is allowed to develop. Mpower analyses the sEMG signal and, based on that, shows the fatigue development.
Strength training increases your power production capability and it has been shown that the increased power production capability is reflected in the EMGsignal.
