Abstract
Introduction Proprioceptive neuromuscular facilitation (PNF) can be used to improve the quality of life of both healthy and diseased subjects, including the elderly, who suffer muscular weakness due to aging, leading to an impairment in functional capacity. Objective Verify the effectiveness of PNF as a tool for functional conditioning. Materials and methods We evaluated a total of ten elderly women aged 60–70 years, clinically healthy and physically active. They had the force of motion of hip flexion with knee extension analyzed by an analog dynamometer. They were then randomly and equally divided into experimental (EG) and control group (CG). The GC was instructed to continue with their normal activities while the GE held 15 training sessions in the lower limb (LL) based on the diagonal D1 and D2. Finally, a new collection wrench the two groups was performed and the data compared. Results There was a significant increase in the average strength of GE, on the order of 31% (p < 0.01). The GC also had increased strength, but not significant (p > 0.05). Discussion : The results confirm that the FNP through initial work of readjustment and proprioceptive neuromuscular activation, and after that, conditioning of the muscle fibers (mainly resistive) is capable of amplifying the force developed by the muscle. Conclusion The PNF was effective as training to gain muscle strength, should be better analyzed as a tool fitness, not to cause health risks, have low cost and easy application.

Proprioceptive neuromuscular facilitation (PNF) can be used to improve the quality of life of both healthy and diseased subjects, including the elderly, who suffer muscular weakness due to aging, leading to an impairment in functional capacity
Randomly divided into a control group (CG) and experimental (EG) and were submitted to the analog dynamometric analysis (Dynamometer analog Crown brand, model AR200, 200 kgf capacity, produced by the Technical Oswaldo Filizola Ltd.) of the force in the Maximum Voluntary Contraction (MVC) of Quadriceps muscle of the dominant leg performing hip flexion and knee extension for 5 s
Ten female subjects aged between 60 and 70 years, physically active and according to the criteria of inclusion and exclusion imposed for the procedures were studied
Summary
Proprioceptive neuromuscular facilitation (PNF) can be used to improve the quality of life of both healthy and diseased subjects, including the elderly, who suffer muscular weakness due to aging, leading to an impairment in functional capacity. Materials and methods: We evaluated a total of ten elderly women aged 60–70 years, clinically healthy and physically active They had the force of motion of hip flexion with knee extension analyzed by an analog dynamometer. The application of PNF physical therapy techniques is Changes in muscle strength in elderly women after proprioceptive neuromuscular facilitation based training 359 based on the usage patterns of diagonal movements of body segments, combining movements of flexion, extension, abduction, adduction and rotation. These are patterns of movement in mass spiral and diagonal form and very similar to the movements used in sports and work activities. This type of motion is consistent with the topographic alignment of the muscles and of structural features of the isolated muscles [4]
