ENERGY SYSTEMS DEVELOPMENT
PART 1
As a strength and conditioning coach & sport scientist, I'm well aware that people perceive my main role within a sports team or with a client is to improve 'fitness'. While this is true, the term fitness itself means so much more. Very rarely do people specify which part of fitness they want to improve or how they are going to do it. Getting stronger, faster, leaner, more powerful could also classify as getting fitter. For the most part though, and it's going to make up the majority of this article, we'll be talking about the commonly thought about 'fit'. Being able to run further, being able to run faster for longer, being able to do something for longer before being tired, also known as 'work capacity'. What is it, how do we define it properly but most importantly, how can we train it properly.
- The ATP-PCr = ATP-Phosphocreatine system. This is for extremely high intensity maximal effort activities and only last about 6 seconds.
- Glycolytic = This utilises glycogen or glucose for the production of energy. It happens in the absence of oxygen, thus by-products build up as a result and this leads to fatigue and the cessation of exercise intensity.
- Oxidative = A multi-step process requiring oxygen. Usually occurs during longer duration activities and is the slowest system at providing ATP to the working muscles.
Doing this requires you to optimise your training in each zone and identifying where your weaknesses lie.
