Active regeneration is a movement method such as a 5-10 minute light jog, that helps to improve blood flow and speed up the rate at which metabolic products are broken down. As with most recovery strategies, there are advantages and disadvantages to this method. The advantages include improved removal of metabolic products such as lactate accumulation and restoring physiological balance (body temperature, heart rate and blood pressure) by maintaining muscle blood flow. A disadvantage is the delayed filling of muscular energy stores, as the muscles continue to consume energy even during active regeneration. Another is that training adaptations are unable to take place, as physiological balance is quickly restored. This method is best used when adaptation is not the main goal.
