Name Relation between physical fitness and study results of primary school students Goal The goal of the thesis is to examine physical fitness of primary school students, compare it with their study results, and see if there is any relatioship between these two variables. Methods Physical fitness is tested with tests and norms of Unifittest (6-60) (Měkota, Kovář, 2002) and study results are generated with questionnaires. The answers are then matched with Unifittest's results of each student. Results are processed with the help of statistical methods. Results The results of Unifittest (6- 60) showed above-average or well above-average level of fitness with 89 % of individuals. Only 11 % of participants reached the average score. The best performance was detected with girls of the 9 ͭ ͪ grade and boys of the 7 ͭ ͪ grade. Spearman correlation coefficient showed a medium-strong relation between the Unifittest (6- 60) results and grades from Czech language, foreign language, and mathematics in 2 categories. 6 ͭ ͪ grade girls had the correlation rₛ= 0,51 and 8 ͭ ͪ grade girls rₛ= 0,56. Other categories showed very weak correlation relation. Keywords Unifittest, physical fitness, studying, youth, sit-ups, pull-ups, long jump, Cooper test
