Study on the development of the motor quality force by using the isometric contraction process
Abstract
The work started from a desire to develop the motor quality of strength through isometric contraction in high school students. There are data in the literature confirming the benefits of these exercises, but it must be kept in mind that an intense isometric effort maintains a state of maximal cortical cell excitation throughout the contraction period, between 10-12 sec. In a lesson we recommend 6-8 isometric contractions twice a week. In this sense, we assume that strength, as a basic motor quality, can be developed by using the isometric contraction process in high school students leading to increased indices of its manifestation. The aim of the paper is to select the most effective individual and pair isometric exercises for the development of the motor quality of strength in 10th grade students. The experiment was conducted at the Ion Nistor Technological High School in Vicovu de Sus, and from the chosen sample we formed two groups: an experimental group and a control group consisting of 6 boys and 10 girls. The experiment showed that, using specific means of the isometric contraction process, significant results were obtained in both experimental groups compared to the control groups.
