Lactate Threshold Report

Decent Essays

The anaerobic threshold (AT), also called the “lactate threshold,” is the exertion level between aerobic and anaerobic training. The AT is the point during exercise where your body must switch from anaerobic to aerobic metabolism. Anaerobic exercise consists of weightlifting, sprinting, and jumping. Once an athlete reaches its anaerobic threshold, lactic acid builds up in the muscles faster than it can be cleared away resulting in muscle cramps. The AT is a useful measure for deciding exercise intensity for training and racing in endurance sports. On average untrained individuals have a low AT (approximately 55 % of VolumeO2max), and elite endurance athletes have a high AT (approx. 80 - 90% of VolumeO2max). lactate threshold.(1) Studies have been conducted on finding methods of improving anaerobic threshold. Lately High-intensity interval training (HIIT) has become a popular training modality in competitive athletes, recreationally-trained individuals, and clinical populations. HIIT consists of repeated bouts of short to moderate duration exercise …show more content…

In the study conducted by Edward H Robinson and Jeffrey R Stout, the use of one weekly interval session at vVO₂max led to a 3% improvement in vVO₂max and a 6% improvement in running(4).The interval duration was set to be 50% of the individual time that the athletes could sustain vVO₂max (the time that VO₂max can be sustained is called tlimvVO₂max or Tmax) which averaged around 3 minutes. The optimum length of VO₂max intervals is not clear although positive results have been found with a range of different interval lengths from 30 seconds up to 3-4
