Document Summary
Energy can neither be created or destroyed, it can only be transformed. Earth"s source of energy is the sun this is a product of nuclear fusion. Distance running is aerobically less power and speed is required. Power is directly related to duration increased duration = decreased power and vice versa (power-duration curve) Anaerobic glycolysis less than 90 seconds, breaking down oxygen. What is energy? the potential to do work (exercise) Energy in biological reactions produces heat if we want to quantify energy you can measure the intake and output of heat then we can calculate the energy being used. Measured in kilocalories (kcals) or joules (1 kcal = 4. 184 kjoules) Kcals and joules are how we quantify the amount of heat used. 1 kcal is the amount of energy required to raise the temperature of 1 kg of water 1 degrees celsius at 15 degrees.
