Ontogenetic Development of Kinematic Parameters of the Running Stride

Authors of the research deal with cross-section analysis of ontogenetic characteristics of basic kinematic parameters of the running stride in terms of age and gender from 7 to 18 years of age. There were monitored: average velocity, stride frequency and length, duration of support and flying phase, as well as other derived indicators at 10 m with 15 m flying start. Sample consisted of 1299 male and 1288 female students of elementary and high schools in Bratislava. Authors determined high age dependency of running speed and stride length on age. On the other hand, there was high ontogenetic stability of the indicators (stride frequency, duration of support and flying phase) in the population of 7 to 18 year-old youth. Ontogenetically stable parameters deteriorated partially in prepubescent and at the beginning of the pubescent period in the age 11 - 15. This relates to rapid growth of body height and weight and deterioration of biomechanical and coordination conditions of an organism. Those finding lead the authors to the conclusion, that ontogenetically stable indicators comprise so called dispositional factors in evaluating the rate of talent for running speed.

The aim of this study was to assess movement patterns by using Functional Movement Screen in three categories of Slovak women’s national football teams during two occasions interpressed with one year. The reason for this was to answer the questions: 1. if there is a tendency to perform better in the screen with respect to age category, and 2. if the players who did the screen more times and recieve recommendations, perform better after a year, irrespective to age category. Our results showed that every category achieved significant improvements (p<0.10) in total test score when compared the two occasions (2013 vs. 2014), except WU17, where significant decrement was found (p<0.01). These results probably represent the fact, that the WU17 is the less experienced category regarding FMS™, and the group where the most turbulence occurs in the nomination list. However, when we assessed the group of players who were present at both occasions of screening, irrespectively to age group they belong, results revealed significant overall improvements (p<0.05). In conclusion, we would suggest FMS™ as a useful tool to reveal potentially weak links in player's movement and therefore determine injury risk. Our results suggest that professional recommendations to remove these are effective and at least as much important as the screening scores alone.
