Here you can see a typical test where the first lactate threshold is at around 210-215 power output and their second lactate threshold is at 260-265. Courtesy of Human Powered Health Performance Labs
Muscles are producing lactate even at rest, with resting blood lactate levels in the 1–2 mmol/L range. [6] Although the lactate threshold is defined as the point when lactic acid starts to accumulate, some testers approximate this by crossing the lactate threshold and using the point at which lactate reaches a concentration of 4 mmol/L of ...
Long slow distance (LSD) is a form of aerobic endurance training used in sports including running, [1] rowing, [2] skiing [3] and cycling. [ 4 ] [ 5 ] It is also known as aerobic endurance training, base training and Zone 2 training. [ 6 ]
Ventilatory threshold and lactate threshold are expressed as a percentage of VO 2 max; beyond this percentage the ability to sustain the work rate rapidly declines as high intensity but short duration energy systems such as glycolysis and ATP-PC are relied on more heavily.
Heart Rate Zone 2. This cardio zone is often referred to as the endurance zone. It’s your base level where your heart is pumping, but you can keep up the pace for a while. Keeping your heart ...
How to calculate your Zone 2 cardio range: Lower threshold: 0.6 x (208 - age x 0.7) Upper threshold: 0.7 x (208 - age x 0.7)
The by-product of anaerobic glycolysis—lactate—has traditionally been thought to be detrimental to muscle function. [13] However, this appears likely only when lactate levels are very high. Elevated lactate levels are only one of many changes that occur within and around muscle cells during intense exercise that can lead to fatigue.
The heart rate increases (approximately) linearly up to the deflection point, where the heart rate reaches AT (also known as LT, lactate threshold, in more modern nomenclature). The test continues for a while, under increasing load, until the subject has gone well past the anaerobic threshold .
