Lactate thresholds (LT) during activities such as running, cycling, rowing, and swimming have been the subject of many studies for the past several decades. However, little is known about the LT parameter during endurance exercises. The purpose of this study was to assess and compare relative and absolute values of LT relative to individual maximal workload during leg-press (LP) and elbow flexion (EF) exercises for both trained (T) and untrained (U) male participants. There was no difference between the relative LT for the four groups (LP-T = 32.22 4.40%; LP-U = 28.0 6.32%; EF-T = 32.22 6.66%; RD-U = 28.88 3.33%). On the other hand, the absolute values for both trained groups (LP-T = 173.0 51.97 kg and EF-T = 18.73 4.13 kg) were significantly different (p< .05) compared to the untrained groups (LP-U = 84.10 18.78 kg; EF-U = 10.81 1.27 kg). The results suggest that the LT for LP and EF exercises are similar only when relative workload is considered.
