Why walking is better than sprinting for fat loss
A quick explanation on why low intensity steady state cardio is better than high intensity cardio for fat loss.
Carbohydrates, fats, and proteins can all be broken down by the body and used as energy. Carbs are the fastest source whereas protein is rarely used. In order for your body to turn fat cells into usable energy it needs to go through a timely series of chemical reactions. This process involves the transportation of the fat cell, through the blood, into the muscle cell, and then the breakdown of that fat cell.
Walking Vs. Sprinting
Sprinting is very taxing on the body. The energy demands are instantaneous. In order for you to move quickly your muscles need the energy right away. It will take that energy in the most readily available source, from in the muscle itself. Your body is working too hard and the demand for energy is too fast; your body doesn’t have the time to metabolize the fat cells.
Low intensity, steady-state cardio
What does that mean? It means you’re walking at a brisk pace but a speed where you’re still able to have a conversation. This allows your body to meet the energy demands using mainly fat cells. Your body is working at a pace that enables the time required for the fat cells to travel through the blood to the working muscles and then break down into energy.
In terms of cardio, this would be the best way to burn fat cells. If your goals are fat loss you can combine low intensity cardio with separate periods of resistance training and watch the fat melt off!
