ESPINOZA-NAVARRO, O  and  VALLE, S. Body Composition and the Effect of an Auxiliary Force Program to Prevent Injuries in Femoral quadriceps, Hamstrings and Biceps Femoris Muscles in Young College Players. Int. J. Morphol. [online]. 2014, vol.32, n.3, pp.1095-1100. ISSN 0717-9502.

The objective of this research was to determine the effects of a program of auxiliary force in the prevention of injuries to muscles: quadriceps femoris, hamstrings and biceps femoris in college football players of the city of Madrid, independent of the normal training program of university club. Twenty-four college players aged 19­28 years participated in the study, divided into experimental group (n=12) and control group (n= 12). In both groups, the displacement and the velocity (potency) were initially assessed through a motion transducer or "encoder". Then in experimental group was implemented a program of auxiliary force for 6 months. The Ethics/Bioethics Committee at the Universidad of Tarapacá, approved the protocols of this research. The results shown in the experimental group, with program of auxiliary forces a significant increase in gain strength/potency, relative to the control group, expressed in watts (1187.6±110.4 vs. 1011.6±110.4 respectively), the percentage recovery of force was 16.8% in the experimental group and 0.1larger than bifurcation aneurysms until they 7% in the control group. The percentage of injured players in the experimental group was significantly lower than the control group (16.6% and 50% respectively). We conclude that preventive programs auxiliary force in football players 19 and 28 years are effective in preventing muscle injuries by the considerable gain strength/potency, providing great economic and sporting benefits. Therefore it is recommended include these programs of auxiliary force in all sports clubs.
