Slowly but surely we might be starting to make some gains ....Could just be the angle.....It's definitely the angle 😂... TOPIC👉🏼 METSs... What if I were to tell you that the 700kcals of cardio on the stair master you just did isn’t really 700Kcals😱? Yep, ever heard of METS a.k.a metabolic equivalents? Well you will now.
METS are essentially the difference between the metabolic rate of the activity you are doing vs the metabolic rate of just resting. So, 1 MET is the amount of energy you need when just sitting on your ass and is roughly ~1kcal/kg/hr. If you then get on a Stairmaster, which is fairly challenging, you may increase to 10METS meaning that you are then burning 10x more by walking up stairs than if you were to sit on your ass BUT cardio machines don’t take this into account as they display the gross calorie burn, not net. You see, when you are doing 10METS on your stair master, time doesn’t just stop, it’s still ticking by and regardless of whether you are doing cardio or not in this time, you will still be burning that minimum of 1MET (~1kcal/kg/hr). Example 👉🏼 A 70kg male sitting on their ass for an hr will burn ~70kcals. The same male doing 10METS on the stair master for 1hr will burn 10x more (~700kcal) but STILL their original 1MET from just being there, alive. The net calories burned are therefore 700kcal-70kcal resulting in a "cardio burn" of 630kcal. Small difference but nonetheless rather interesting...
Furthermore, cardio machines in general are still pretty inaccurate. I remember using my hr monitor during my cardio bunny days and when the machine would display a 1000kcal burn in 1hr of stairs, my monitor showed more like 650-750kcal. The machines are usually very generous in their calculations. So, does this mean anything should change? No! If you do 600kcal on a given machine per day then keep it that way. At the end of the day it doesn’t matter what number it shows as long as it’s the same every time you do it. Consistency is key. Just an interesting topic I thought you may like to know. Just sayin 🤓
