Abstract
[b]Aim of the study[/b]. The goal of the research was to assess the scope and direction of inter-generational changes (secular trends) of physical fitness components studied in the health convention (Health-Related Fitness), and using the authors’ point scales. [b]Materials and methods[/b]. The comparative analysis was based on the research results collected from 1993 to 2002 (a total of 23,600 people, including 10,600 girls and 13,000 boys) and on observations made from 2002 to 2011 (a total of 11,520 people, including 5,390 girls and 6,130 boys). The subjects were students at primary and secondary schools in southeast Poland. Statistical analysis was conducted on both the raw measurements and the scores converted into points on a T-scale. New point tables were developed using the materials collected at the beginning of the 21st century.[b]Results and conclusions[/b]. The proposed method of scoring on a T-scale, which consisted of calculating a normalized ten scale jointly for girls and boys of all age groups, proved to be a good tool to capture both the comprehensive dynamics of morphological, functional and motor development, as well as long-term trends of changes in the components of health-related fitness. The results have provided evidence challenging current views on the existence of “opening scissors phenomenon” in the biological development of young Polish generations. In the last decade, there has been a tendency for the desired inter-generational changes in components such as cardio-respiratory, musculoskeletal, morphological, and motor – all of which can be regarded as positive indicators of health. Their scope has been so significant that it justified the need to update existing point tables of physical fitness. Therefore, on the basis of the latest materials, new scoring scales have been developed that utilize the authors’ calculations.
