The science behind DRS(Dynamic Recondition System)-C is complex, but I will try my best to break it down. When you train in the presence of enough oxygen (such as walking, light jog etc), the body will use the aerobic pathway to provide the energy it requires. When your body can no longer receive enough oxygen it then switches to a different pathway called the anaerobic pathway. In terms of DRS training (and for fat burning) this concept is key. When you work in the anaerobic pathway, such as during sprints, you begin to increase your ‘resting metabolic rate’. Your RMR is the amount of energy you use at rest, therefore the higher this is the better. This occurs by an increase in the EPOC effect (Excess Post Exercise Oxygen Consumption). Think of this as the after burn from an intense exercise session.
EPOC (Excess Post Exercise Oxygen Consumption)
Boosting the EPOC effect of exercise also has the added ability that it heightens our V02 Max. This is the amount of oxygen our body can use (ml) in one minute, per kilogram of body weight (ml/lg/min). Increasing the VO2 Max, you can therefore intake and process more oxygen, leading to enhanced performance.
Post DRS Fat Burning
DRS training doesn’t use much fat for fuel during the session (predominantly glycogen), however afterwards, the metabolism remains high as the body begins to use fat as fuel. Post DRS, the body tries to revert back to its pre-workout state of using both glucose and fat as energy sources; however, to restore the now depleted glycogen stores, the body must conserve whatever glucose/ glycogen that remain, and to do this it means that the energy source must come from fat. This can lead to an elevated caloric expenditure for around 14-15 hours AFTER you have finished DRS training. With LISS (low intensity steady state) cardio, you lose this affect almost as soon as you are done.
When it comes to DRS, my preferred choice is to get outside and do more body weight workout than using machines. I have researched, applied and included several DRS Training workouts.
