Glycolytic - the breakdown of glucose by enzymes into pyruvic and lactic acids with the release of energy (ATP).
Phosphagen - the use of creatine phosphate stored in the muscles to generate energy (ATP).
concluded from their research that 8 minutes is all you should take during track speed workouts over anything up to 800 metres - even those going deep into lactate build up.
Energy production is both time and intensity related.
Running at a very high intensity, as in sprinting, means that an athlete can operate effectively for only a very short period of time where as running at a low intensity, as in gentle jogging, means that an athlete can sustain activity for a long period of time.
The breakdown of glucose or glycogen in anaerobic conditions results in the production of lactate and hydrogen ions.
The accumulation of hydrogen ions is the limiting factor causing fatigue in runs of 300 metres to 800 metres.
The cost of replacing batteries varies depending on the design and scale of the system.
Any back-up generator will also have its own fuel and maintenance costs.
The thresholds (T) indicate the point at which the energy system is exhausted - training will improve the thresholds times.
Adenosine Triphosphate (ATP) stores in the muscle last for approximately 2 seconds and the resynthesis of ATP from Creatine Phosphate (CP) will continue until CP stores in the muscles are depleted, approximately 4 to 6 seconds.
Wind turbines harness the power of the wind and use it to generate electricity.
About 40 per cent of all wind energy in Europe blows over the UK, making it an ideal country for domestic turbines (known as micro-wind or small-wind turbines).
Actively contracting muscles obtain ATP from glucose stored in the blood stream and the breakdown of glycogen stored in the muscles.
