The purpose of the research is to optimize the development of high school students' resistance through integrated work using means and methods specific to football. Experimental verification of the effectiveness of the specific means of football playing in the development of high school students' resistance. The experiment was carried out on 681 subjects. For the development of resistance, the independent variable was implemented in the subjects of the experimental sample. All subjects were predictive and summative in the 10 samples: three motor samples, three functional samples and four somatic samples. The specific methods used in the experiment for the development of resistance were based on uniform efforts, varying intervals and efforts, with appropriate dosages leading to progress. In the final evaluation, the subjects of the experimental sample and of the reference sample progressed towards the predictive assessment, but those of the experimental sample progressed more than the subjects of the reference sample to all the samples and tests given. The effectiveness of implementing the independent experimental variable in the experimental sample subjects was 61% compared to the subjects of the reference sample. In the experiment, we used the statisticalmathematical method using arithmetic mean, median, modulus, standard deviation, amplitude, mean error, variability coefficient, Student test, Pearson correlation coefficient, Epsilon test and Z test. Higher progress in the subjects of the experimental sample. The difference between the mean of the experimental sample and the reference sample was significant at the significance threshold p <0, 05, with a probability of 95%. The value of the Pearson correlation coefficient is very high (between 0.9 and 1) to 83.33% of high cases (between 0.7 and 0.9) to 13.88% and mean (between 0.5 and 0, 7) in 2.79% of cases, meaning that the results obtained at each sample are significant. The progress of the subjects in the experimental sample was superior to the progress of the reference sample, so we can state that the dependent variable is significant, the assumptions of the research are verified and validated.
