Today’s corner is all about Training Zones and the terminology associated with them.
The body has two clear energy systems, aerobic (with oxygen) and anaerobic (without oxygen). Anaerobic is divided into two. PC (Phosphate Creatine) which is about dynamic power / speed for 2-10sec. The second is LA (Lactic Acid) which is about sustained power / speed for 10 - 60sec.

This is naturally due to the reduced level of impact.
