The development of noninvasive near infrared spectroscopy (NIRS) to monitor tissue oxyghemoglobin/myoglobin saturation provides a means of continuously and noninvasively monitoring muscle oxygenation during exercise (1-3). The lactate threshold has been. used to gauge endurance training (4,5). It would be of interest to determine whether the noninvasive monitoring of muscle oxygenation can be used as a surrogate marker of lactate threshold or as a gauge of conditioning during endurance training. The ability to identify the lactate threshold by a noninvasive, continuous monitor such as NIRS would greatly aid athletes in assessing their level of performance during training and to guide that training.
