Is EPOC really that significant for our caloric burn post-workout?
As a powerlifter, my world revolves around numbers, PRs, and the sweet satisfaction of pushing iron. Yet, I find myself pondering the concept of Excess Post-Exercise Oxygen Consumption (EPOC) and its supposed magic in calorie burning after a workout. I mean, am I truly racking up the calories just from lifting, or is it more of a tantalizing whisper than a roar?
Research by Schoenfeld et al. (2014) suggests that the magnitude of EPOC is influenced by the intensity and duration of the exercise. The paper mentions that high-intensity sessions create a greater EPOC effect, though they also reveal that the actual caloric expenditure may not be as impressive as the hype. Effect sizes, as they put it, are modest, usually in the range of 5-15% of total calories burned during exercise. So, while the idea of torching calories in the hours after a lift is appealing, one must wonder if the reality holds up.
Further digging into the work of Helms and colleagues (2018), they discuss the metabolic impact of different lifting styles. It appears that while EPOC does exist, the actual calorie burn can be somewhat underwhelming for us powerlifters compared to those who favor endurance training. This doesn't mean we should toss our weights aside; rather, it highlights the importance of understanding the nuances of our training. If we approach EPOC like a mirage in the desert, perhaps we can focus more on what truly drives our gains. Is it the weights we lift, or the mind we cultivate around them? After all, it's not just about calories burned but the journey of self-improvement that fuels our fire! What do you all think about the significance of EPOC in your training? Worth the focus, or just a side note?
