Is Interleukin-6 the 'holy grail' of exercise mediation?
...urnal. However, the actual appearance of IL-6 into circulation
depends on several factors including exercise intensity, duration and mode. For instance, vigorous rowing doubles the amount of IL-6 in plasma relatively quickly, while in endurance activity IL-6 doesn't appear until later. Activation of the IL-6 gen...
