A person's lactate threshold is when the production of lactate exceeds their body's ability to clear it from the system. Research suggests training around one's lactate threshold could be Tempo pace is different for everyone, which is part of the appeal of this training technique. It's customized to your current running capabilities, and it changes when you do. Much like aerobic exercise is a workout for your heart, training at your lactate threshold is a workout for your muscles to practice clearing lactic acid buildup. So, what is Threshold training? This is running at a pace where lactate does not rise significantly in the blood during the run, but rather, it stays at a constant level. Essentially, it is the point JUST BEFORE the moment where the amount of lactic acid build-up is greater than the body can efficiently get rid of. Lactate-threshold pace is about 10 to 15 seconds per mile slower than 5K race pace (or about 10K race pace) for slower runners (slower than about 40 minutes for 10K). If using a heart-rate (HR) monitor, the pace is about 75 to 80 percent max HR. Establishing threshold pace. The proper pace for T-pace running is about 83 to 88 percent of VO2 Max, or 88 to 92 percent of vVO2 Max or maximum heart rate. In the endurance world, the term Lactate Threshold is commonly used to refer to the heavy-severe intensity domain boundary. It is sometimes used interchangeably with the (now obsolete) anaerobic threshold. We use intensity domains to describe distinct physiological responses to exercise. Getty Threshold work is one of the cornerstones of training for runners who are tackling distances from 800m to ultras. Your lactate threshold is the point at which lactate is produced and Your lactate threshold pace is what runners call the pace they can maintain for around an hour. To find out more about lactate threshold, and to discover our own, we went for a physiological assessment with strength and conditioning coach Graham Ferris at Pure Sports Medicine St Paul's . n2AQy.
