The purpose of this study was to analyze if both the Banister’s TRIMP method and the Foster method are convergent to calculate the training loads in Taekwondo athletes. There was a total number of 8 Taekwondo athletes as participants, of which composed of 4 women and 4 men. Together, the participants performed a total number of 61 training sessions. The study also had a significant Pearson correlation found between the Banister’s TRIMP and Foster’s method (r= 0.33, p ˂ 0.01), but according to Lin’s Concordance Correlation Coefficient, the measurement was very low (Rc between 0.002 and 0.022). An individual correlation was also made through the Pearson Product-Moment between the two methods and through this it was discovered that only one participant had a significant association (r=0.812, p˂0.014), but with Lin’s Concordance Correlation Coefficient, the result was low (Rc between -0.004 and 0.037). In conclusion, both the Banister’s TRIMP method and the Foster method are not convergent to measure the training loads in Taekwondo athletes.
