The Impact of Using Modern Fitness Techniques vs. the Traditional Ones on the Strength of the Lower Limbs in Adolescent Girls

Summary/Abstract: The issue of this paper is focused on identifying the positive influence that the means of fitness exert on the human body, as well as the ways to practice it, as an option for adopting an active lifestyle. As a component of fitness, along with cardio-respiratory endurance, mobility and body composition, strength fully contributes to daily activities, with vigor and efficiency, and to increasing human performance, with effects on quality of life. Physical activity performed systematically, regularly contributes directly to improving the structure and functions of various organs and systems of the body. In the current pandemic context, exercising can counteract the appearance of anatomical and functional impairments or correct certain dysfunctions that occur as a result of improper living and / or working conditions (spending a long time in front of the computer, sedentary lifestyle, unhealthy diet). This topic is part of the concerns that link the goal of maintaining and improving health, with the development of a working concept in which exercise becomes a flexible tool to achieve the objectives of structural-functional development of adolescent girls and increase autonomy. in performing physical activity. In this regard, we started a study that investigated the impact of modern and traditional fitness techniques on the development of lower limb strength in adolescent girls. This study is part of the amelioration type research. The research took place at the National College „G. Moisil ”(Bucharest), on a sample of 40 students, aged between 15 and 16 years. The action systems used to develop strength were based on the principle of varying muscle tension. Following the intervention program and the support of the tests, statistical data showed an improvement in muscle strength in the lower limbs in the subjects of the experimental group, compared to the control group.
