The XCO resembles classic cufflinks but its function and its objectives are very different. Thanks to the acceleration and braking of a loose mass granulated within a hollow aluminum cylinder exercises can be in different directions. The job is to accelerate this loose mass to stop it at the end of the movement and return to accelerate in the opposite direction. This movement of jig – also called reactive training – get that they will stimulate and train muscles, ligaments, tendons, bones, joints, capsules and nerve endings. Another feature of the XCO, compared with workouts that are performed with conventional apparatus in which exercises are uni – and bilateral and that only isolated muscles work, is that with the XCO chains and muscle groups in three-dimensional drawings can work with what the force generated will be much more global and will be working muscles agonists and antagonists in the same year.
This type of exercise is called functional kinetics. Aside, force It develops with these exercises is eccentric, and this is something unique that can only be achieved with very few exercises or devices. The use of the XCO is wide, it can be used as a fitness device in amateur athletes as it can also be used by professional athletes to improve performance and prevent and treat injuries. Currently lots of clinics used the XCO as a therapeutic tool in rehabilitation processes both in injury of the upper limb and trunk and knee injuries. Shoulder-subacromial syndrome, supraspinatus tendinopathy, instability of shoulder pathologies – recover long before using this type of exercises. Column lesions, such as cervical or lumbar hernias can also benefit from working with the XCO. On the other hand, the Flexi-bar, an arc with which made rhythmic oscillations is a device extremely suitable for body global training and for the isolated segmental work.
