There are many different training protocols available for the hamstring muscle group. Training for injury prevention has rightfully received a lot of attention as hamstring injuries are especially debilitating to many athletes. Exercises used for hamstring injury prevention are well described in the research by Askling and co-workers. However, there is no quantification and subsequent evaluation of force output in either the concentric or eccentric phase of these exercises.
A solution for precision training is found in the 1080 Quantum system. Offering different resistance types including isokinetic contractions, it measures both the eccentric and concentric forces with high accuracy. A virtually unlimited range of exercises can be performed both vertically and horizontally. The video shows examples of how force output can be monitored over the training or rehabilitation cycle. Comparing force output between the left and right side completes the picture.
