The aim of this master's thesis was to determine the connection between some morphological characteristics and lower extremity strength indicators of female football players from two women's football clubs in the U15 category. The sample of participants consists of 40 football players, 20 from each club. The criterion for the selection of test subjects was their year of birth (2008, 2009, 2010). The dimensions of the morphological characteristics that were measured in the research are: body heihgt (TV), body weight (TT), sitting height (SV), leg length (DN), upper leg circumference (ONK), lower leg circumference (OPK), while the indicators of strength were force in the muscle during extension (EKS), flexion (FLE), abduction (ABD), adduction (ADD). Through statistical processing indicators of descriptive statictics were calculated, those were arithmetic mean (AS), standard deviation (STD. DEV.), minimun (MIN) and maximum (MAX) result of each variable. The Kolmogorov – Smirnov test was used to analyse the normality of the distribution of all variables, all variables are normally distributed except for the leg length variable. Pearson's correlation coefficient established a connection at the level of significance p < 0,05 of all morphological characteristics with strength during extension, abduction and adduction, while the connection of strength during flexion was confirmed with body height, sitting height and upper leg circumference. Given that the leg length variable was not normally distributed, Spearman's correlation coefficient determined a statistically significant connection with all indicators of lower extremity strength at the p < 0,05 significance level. Finally, t-test was used to analyse the difference between the teams and a statistically significant difference was confirmed only in the strength during extension and strength during adduction at the significance level od p < 0,05.
