Electronic devices have been useful to evaluate muscle fatigue and activation, co-ordination and metabolic consuption among different sports activities. Since these important variables have not been investigated during fitness training, the present study aims to analyze the activity of the major muscles of the lower extremity during training activities on a cardiofitness apparatus (Cardio Wave
- Gambettole, Italy). This device is able to stimulate the multiplanar movements of lower limbs by combining various types of movement according to the physical principles of human motion. Working simultaneously on three axes by a sliding movement of lower limbs should activate different muscle groups following four positions at different intensity level. Muscles activity and training effectiveness were evaluated by monitoring Electromiography signal, metabolic data, oxygen uptake and heart rate. The goal of this research is to develop a system able to manage different information coming by varius electronic devices.
