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 ...
"The most common cause is related to an over-accumulation of cholesterol, and possibly calcium, within the vessels, resulting in a low blood flow state, which would cause cold feet." 3. Raynaud ...
