Often, exercisers need to know the number of calories burned during specific exercise routines. Most modern exercise machines perform this function, and there are some older machines that may indicate this information.
There are people who adopt other methods of exercise and do not use exercise machines and also need to know the number of calories burned, for example, walking versus running. It’s different and it may not be what you think.
Burned calories are not dependent on speed, body weight or oxygen amount alone, but rather a combination of these which are advantageous for fast walking or fast or slow running. Numbers can be anticipated to get the best benefit in optimal calorie burning.
Different aspects related to the calories burned when walking versus running have been the subject of studies at various universities. Medicine & Science in Sports and Exercise published the results of an investigation that measured the actual calories burned among 12 women and 12 men during walking and running; showed that men who weighed more burned more calories, while in both groups it showed that running burned more than walking.
Oxygen consumption is a partial explanation. A liter of oxygen consumed burns five calories, which means that during the race, which increases oxygen consumption, more calories are burned. In cases of excessive body weight and limited physical capabilities, walking will increase oxygen consumption.
The general rule of thumb in situations where weight is controlled and physical capabilities and oxygen consumption are normal, runners burn about 10 calories per minute and walkers burn about 5 calories per minute.
Results depend on conditions; For example, when walking briskly, an overweight person with limited physical abilities will burn more calories due to the extra weight and increased oxygen consumption. However, as a person’s physical abilities and weight improve, calories burned will decrease for the same amount of effort.
Running requires less time than walking to burn the same number of calories. Many people who have limited time to train find that running fits well into their daily routine. Runners with just 20 minutes of exercise can burn 200 calories compared to 100 calories for walking.
Running has disadvantages, such as increased wear and tear on the knees and hip joints – cartilage damage increases as the weight falling on these body parts creates additional stress. Brisk walking does not create the same stress on body parts and increases calories burned with increased oxygen consumption. Therefore, runners suffering from knee and hip problems can continue training by walking.
