A Problem in Football
Calcium is one of the sports with the highest risk of muscle injury, especially to the lower limbs. The most affected muscle groups are the back thigh muscles (hamstring), adductors, quadriceps and calves. The risk is aggravated by explosive movements such as sprints, change of direction and kicks, which critically solicit these structures. Relapses are frequent and lead to long periods of inactivity for athletes, with serious economic consequences for clubs
Extent exercises: key to prevention
Numerous studies show that eccentric exercise, that is, the one where the muscle stretches under tension, is particularly effective in preventing injuries. This type of contraction promotes neural and mechanical adaptations that increase muscle resistance to stretching, reducing the risk of damage. In particular, it was observed that eccentric work improves muscle strength, coordination and ability to absorb high loads
What is is isoinertial technology?
Isoinertial technology is based on the use of flywheel devices, such as the system Desmotec. These tools allow dynamic training, better simulating the real movements of sport. During training, the athlete gives force to the flywheel in the concentric phase and then must restrain his inertia in the eccentric phase, thus obtaining an eccentric natural and effective overload
Applications in rehabilitation
In the field of rehabilitation, this technology has shown positive results in patients with patellae tendinopathies, anterior cruciate ligament injuries and under prolonged immobilisation conditions (such as bed rest or even space flights). Training with eccentric overload has led to an increase in muscle mass, strength and functionality, proving to be a valid support even in the most complex cases
Prevention of injuries in footballers
In prevention, isoinertial devices were successfully used to reduce injuries to hamstrings, particularly femoral biceps, one of the most prone muscles in footballers. Inserting specific workouts with eccentric overload in pre-sampled preparation proved useful to increase muscle strength and prevent new injuries.
Final considerations
Isoinertial technology is an important innovation for training, prevention and rehabilitation in football. However, the literature highlights the need to develop standardised protocols for its use in order to maximise its effectiveness. Therefore, more experimental research is needed to consolidate the use of these instruments within systematic programmes, both in clinical and sports.
