The muscle strength is one of the main physical components and is associated with the quality of movement execution in the everyday activities and sports performance. To quantify and classify the levels of strength is very important for decision making in the physical exercise prescription and therapy. The aim of this study is to quantify and classify the muscle strength in a sample of healthy men from different ages.

Method 29 men were included, average age of 40,33 ± 10,92 submitted to a muscle strength evaluation with a dynamometer digital manual in the Sports Medicine Institute of Mãe de Deus Hospital in Porto Alegre. The individuals were positioned in ventral decubiti and oriented to execute knee extension and flexion in an initial angle of 90 and 180 degrees, respectively, counter resistance. The peak strength measurement was accomplished by a portable dynamometer. (Lafayette Manual Muscle Testing System, Model 01165). The individuals were categorised in different ages and classified by percentis.

Results The results of peak strength of knee extension and flexion of both members were presented in tables 1 and 2, as follows:

Abstract P-54 Table 1

Strength peak of right and left knee extension, respectively.

Abstract P-54 Table 2

Strength peak of right and left knee flexion, respectively.

Conclusion The muscle strength evaluation with a manual dynamometer is a validated method. It is convenient to serve as a complementary test to aid in the prevention and treatment of lesions. We present in this initial study to find out extension and flexion strength of knees in a group of healthy men in order to prepare of normative data tables, since we have little data on this subject in the literature. We conclude that further studies should be made in the future with Muscle Function Tests by Digital Manual dynamometry to generate a database with more consistency.
