Aim: We tested elderly male and female patients analyzing their reaction to electro stimulation training programs as well as the efficacy of this training protocol as prevention of sarcopenia affecting quadriceps femoris muscle. We collected all patients anthropometric data, physical parameters and isometric strength. Then we assessed any parameter variation occurred before and after training. Methods: We supervised three male and three female patients presenting with specific conditions related to parameters aforementioned. A 8-week training program was carried out as patients underwent specific therapy three times per week for a total of 24 neuromuscular treatment sessions. We estimated each value as patients’ weight, height, BMI—body fat percentage and a three level measurement of the thigh circumference as dominant limb (the latter tested in males only). Further tests on isometric strength were performed before and after each leg workout using a leg extension machine equipped with a load cell. Results: Tables and graphic layouts display irrelevant weight and B.I. M variations in each patient. Variations of medium and low thigh circumference were found instead 0.69 %\medium circumference percentage increase\1.25 %; 1.16 %\low circumference percentage increase \1.74 %. Maximum isometric strength percentage increase was relevant except in a female patient who showed a little percentage decrease instead. Conclusion: Fibres have displayed greater hypertrophy within quadriceps extensor following electro stimulation therapy. Muscular Sport Sci Health 123 cross sectional area of the front thigh has increased as well as lower limb strength. As a result, electro stimulation proved to be successful in arresting sarcopenia and promoting muscle mass growth.

Abstract
Aim: We tested elderly male and female patients analyzing their reaction to electro stimulation training programs as well as the efficacy of this training protocol as prevention of sarcopenia affecting quadriceps femoris muscle. We collected all patients anthropometric data, physical parameters and isometric strength. Then we assessed any parameter variation occurred before and after training. Methods: We supervised three male and three female patients presenting with specific conditions related to parameters aforementioned. A 8-week training program was carried out as patients underwent specific therapy three times per week for a total of 24 neuromuscular treatment sessions. We estimated each value as patients’ weight, height, BMI—body fat percentage and a three level measurement of the thigh circumference as dominant limb (the latter tested in males only). Further tests on isometric strength were performed before and after each leg workout using a leg extension machine equipped with a load cell. Results: Tables and graphic layouts display irrelevant weight and B.I. M variations in each patient. Variations of medium and low thigh circumference were found instead 0.69 %\medium circumference percentage increase\1.25 %; 1.16 %\low circumference percentage increase \1.74 %.
