Profile and analysis of the relationship between strength and speed of American football players

Title: Profile and analysis of the relationship between strength and speed of American Football players. Aims: The main aim of this study was to analyse the profile and relationship between strength and speed of American Football players. The research was taken to find, to what extent does strength and speed correlate including the test battery and if so, does the higher level influence results of the motoric tests. Methods: In our research we applied methods of analysis and comparison. The method of analysis was used in detailed breakdown of the measured results of the motoric tests. The comparison method was used to determine relationships between specific motoric tests. We carried the basic statistical processes of the measured data, which included calculation of the measurement of arithmetic mean, mode, median, minimum and maximum value, upper and lower quartile and variables. Range of scatter, deviation and quartile range together with variation coefficient. Relationships between motoric tests have been calculated by Pearson's correlation coefficient. Results: Statistically significant correlations were found between the tests of linear speed - 10 and 40 yard dash (r = 0.86) and tests of agility- 20 yard shuttle a 3 cone drill (r= 0.77). The correlation approached significance between other..
