The use of measuring BLC in endurance athletes to evaluate exercise performance has been practiced for years (22-25). Some of the most common uses for BLC analysis include training adaptation analysis, identifying intensities in endurance exercise, predicting race outcomes, and prescribing endurance exercise with precise exercise intensities (2). The majority of the prescriptive work for exercise leans toward the estimated amount of contribution of the aerobic system during exercise based off of lactate formation and the determination of the anaerobic threshold (1). The most common type of test athletes undergo is the lactate threshold (Tlac) incremental exercise test (IXT). This test is meant to predict the maximal workload at which lactate

In all, the test usually consists of a maximal oxygen uptake (VO2max) IXT test and three to eight, thirty-minute constant-workload tests. The MLSS has been defined as the maximal workload an athlete can perform at without a 1 mMol·L-1 increase from minute ten to minute thirty (9). Each of these tests must be performed at least 48 hours from each other. Thus, if the test is performed continuously, it could take eight to eighteen days to complete. Currently, researchers are seeking for quicker ways to accurately predict the MLSSworkload, hence the Tlac …show more content…
The Tlac is one of the most commonly used tests to assess the athlete for prescribing exercise intensities and predicting performance outcomes because of its convenience. The terminology and methods of testing this parameter have been changed over the years. Nonetheless, this physiological parameter is obtained from one VO2max IXT that lasts about 12 to 18 minutes. The VO2max test typically consists of two to five minute stages with increasing workloads until volitional exhaustion. During the test BLCs are observed at the end of each stage to form a lactate curve. The point in the curve that shows a nonlinear increase is termed the Tlac
