Why is sprinting different than regular cardio
Sprinting is an intensive activity that tests the body to its limits. Within a few seconds, heart rate accelerates, ventilation increases, and major muscle group activation occurs. Such intensive exercises compel the body to work with energy that is metabolized quickly but inefficiently by the body, causing stress that the body tries to correct afterward.While jogging or walking is a process of aerobics, sprinting is more anaerobic. Anaerobic systems produce energy quickly. This is what creates a higher energy debt that must be repaid by burning calories after the session is over.
Understanding the 36 hour effect
After such strenuous physical activity, it does not return to its normal state easily. Instead, it remains engaged in efforts to restore oxygen levels, repair muscle tissues, remove metabolic wastes, as well as rebalance hormone levels. This phase is called Excess Post Exercise Oxygen Consumption or EPOC.
Studies that were printed in the likes of the Journal of Applied Physiology and Sports Medicine have found that intense exercises can increase resting energy levels for as long as 24 to 36 hours. This is dependent upon the intensity of the exercises, total efforts, fitness levels, and recovery conditions.During this phase, metabolic rates are higher than usual even at rest. Both fat, carbohydrates, and proteins work collectively for energy release. This is where the term “fat burning for 36 hours” originates from, despite being a bit too simplistic.
What the science actually suggests
Research comparing sprint intervals to moderate aerobic activities demonstrates a more significant metabolic response after the exercise for sprinting. In one study in the European Journal of Applied Physiology, it was found that shorter bursts of sprinting triggered a more substantial afterburn effect than longer endurance exercises despite shorter total exercise times.A body of research also identifies enhanced insulin sensitivity with sprint training. Improved insulin regulation translates to the body becoming more adept at dealing with glucose levels, reducing the possibility of fat accumulation from excess calories. This, in turn, leads to positive body composition without necessarily engaging in weight loss or gain.There is also the role of hormonal responses. In sprinting, there is the elevation of adrenaline levels as well as noradrenaline, which is attributed to the breakdown of fat. These hormones continue to be high even after training, contributing to the additional burning of calories.
What this does not mean for fat loss
A degree of realism is in order here. One sprint session will never produce enough fat loss for you to actually see it. This is true even with the extra calorie burn that occurs during recovery. This is important to understand about fat loss.Sprinting is more effective as it is incorporated into a balanced regimen that includes proper eating, weight training, and resting. If any of these factors are missing, no amount of vigorous exercise is effective.
Who should be careful when sprinting
Sprinting is a demanding activity for the joints, tendons, and nervous system. It is not advisable for either beginners or injured persons to immediately engage in maximal-effort sprinting, as this could enhance the risk of injury. Research suggests that gradual progression is advisable.A number of people would potentially get the same metabolic benefits through modified intervals or intensive cycling.Sprinting can stimulate metabolism for as long as 36 hours by placing additional recovery demands on the body. This is an indirect way of fat loss that does not occur instantly.
Science explains the process, not the magic. When sprinting is utilized effectively, it is a great productivity tool. When it is pitched as a fix for one event, it totally misses the point. That still requires repetition.
