Abstract

Aim: The purpose of this study was to evaluate time to exhaustion analysis in soccer players based on their HEART RATE changes slope and BLOOD LACTATE changes in a gradually increasing test.Methodology: the participants in this research project were 20 soccer players of the first division club with an average age of 19±1.58 yr, 179 ±6.26 height cm and 66±8.64 kg weight. Time to exhaustion and BLOOD LACTATE changes were measured during the incremental ramp test. Likewise during the steps of heating, running ramp protocol and cooling the Subjects HEART RATE First Division clubs in the country were the participants in this research project. Laboratory tests increased time to exhaustion, lactate changes during the ramp incremental test were measured. HEART RATE at all stages of heating, and cooling ramp protocol run by a Polar HEART RATE meter and recorded Measurement Was and HEART RATE threshold and slope changes using Mathematical software and Dmax method for individual subjects were calculated. Running The Kolmogorov Smirnov test and ensuring the availability of the application of parametric statistical test, Pearson correlation coefficients were calculated between the variables. All statistical procedures using SPSS software and survey data at a significance level of 0.05 was used.Results: based on results of research the correlation HEART RATE changes slop were r=- 0.76 with BLOOD LACTATE and r=- 0.67 with the time to exhaustion.Conclusions: The Research findings showed that, Because of using accurate mathematical methods in Calculating and plotting the HEART RATE changes slope, utilizing such HEART RATE changes slope to measure the fitness of athletes by coaches and athletes is recommended.
