Three Surprising Revelations About the Energetic Costs of Weight Training | Effects of Intensity, Rest, Speed & More

Written by | published on

The patterns that emerge in Figure 1-3  already suggest that Crossfit gyms are the places where the average user will "leave the most calories" on the floor. Even regular circuit training programs burn ~10kcal/min (Gettman 1981). Graduate research from 2013 suggests that exhausting Crossfit workouts can burn as much as 20kcal/min (Babiash 2013). From previous SuppVerity  articles, you will remember that the number of calories the classic cardio equipment will tell you you'd burned during your last session often is completely off. You have also learned about a year ago that even the best fitness trackers have a margin of error of ~10% - and that's for walking, jogging or running, where it's really easy to estimate the energy requirements. And, assuming that you've been around for quite some time, you may remember that there's credible evidence that we systematically underestimate the energy expenditure of push-ups, pull-ups, burpees and other bodyweig...

Role of Muscle and CNS in Diet-Induced Decline of Exercise-Induced Energy Expenditure | Caffeine & Nicotine May Help!

Written by | published on

While "calories count" when it comes to losing body fat, the notion that you would always burn the same amount of energy with a given workout - irrespective of your energy intake - is completely bogus and only one of the reasons why meticulous calorie counting won't work.  Let's address it right away: Yes, the paper Tariq I. Almundarij et al. published in the peer-reviewed journal "Physiological Reports" (Almundarij 2017) deals with a rodent experiment, but  with the goal of the study being to identify the fundamental mechanisms behind, not the extent of metabolic adaptation to calorically reduced energy intakes, this does not disqualify its results as irrelevant for humans - on the contrary (and trust me, I'd prefer a human or at least a pig study, too). With that being said, let's take a look at what the scientists did to "investigate the role of MC4R in the modulation of muscle work efficiency, and test the hypothesis that energy restri...

Update: The Latest on Caffeine, Exercise, Fat & Weight Loss - Increased Performance, Energy Expenditure (6%) & Fatty Acid Oxidation (27%) vs. Decreased Sleep Quality & Burnout

Written by | published on

We love coffee! There is not doubt about it 85% of the Americans consume coffee on a daily basis and it's not much different for the rest of the West (Mitchell. 2013). Caffeine is the #1 drug worldwide (Weinberg. 2001; Mitchell. 2013). In the US people with a death wish select the coffee from the eponymous brand which contains more than twice the amount Starbucks coffee does - and that in spite of the fact that Starbucks is the not so close follow up on place in a ranking with the telling title "Amount of caffeine in coffee in the United States in 2013, by brand (in mg per floz)" (Thrillist | Statista.com. 2014). With 54.2 mg of caffeine per floz and thus ~ 400mg per cup "having a Deathwish" would bring an average male athlete with a body weight of 80kg right to the 5mg/kg body weight maximum that has been used in the majority of high(er) dose caffeine supplementation trials.

Do We Systematically Underestimate the Energetic Costs of Push-Ups, Pull Ups, Squats & Co? Study Says Anaerobic Exercises Burn 2x More Energy Than Previously Thought

Written by | published on

If we go by the data from the Verzina study, push-ups and pull-ups burn 50% and 62% more energy than we previously thought they would. Against that back- ground it's no wonder that participants in the Smith study ( more ), I wrote about pre- viously got from 16% to 8% body fat. "Do We Systematically Underestimate the Energy Expenditure During Anaerobic Activities?", that's not just the question the headline of today's SuppVersity article eventually implies, it is also an essential question with a potentially consequential answer I came up with, when I read a recent paper by scientists from the Department of Exercise and Wellness at the Arizona State University (Vezina. 2014). The said paper presents an examination of the differences between two methods of estimating energy expenditure in resistance training activities and concludes that (a) "the methods we use to calculate the EE of anaerobic activities significantly affects EE estimates" and (b)...

The Fallacy of Working Out To "Burn Calories" + Exercise Shuts Down the Carb Cravings: Bench Press, Leg Press HIIT & LISS Are Not Meant to Incinerate the Junk You Eat

Written by | published on

If you work out to be able to allow yourself to eat, you know you have a serious problem. So, what was that about the bench pressing consuming as much energy as leg presses and the "exercise just makes you hungry myth" on the last installment of the Science Round-Up ? If that's what you have been asking yourself this morning, when you showered I am impressed - or should I be worried? If you have not done so already, this would be the right time to download + listen to the Science Round-Up - I promise there is much to learn and not all of it is going to be repeated here. Whatever... in the end it does not matter how urgent you were waiting to take a look at the data that supports my argument that (a) exercise does not just make you hungry, and that (b) the notion to work out primarily to burn energy is hilarious. Chest vs. legs what's energetically more costly? While I could imagine that the comparison would have yielded a different result if the 10 healt...

Tabata Workouts: Do They Work & How Energy-Demanding Are They? 14.5 Kcal/Min Sounds Nice, But You Must Earn It!

Written by | published on

Tabata training is intense: So if you don't have the guts to do it on your own, find someone to suffer next to you. Trust me that'll keep you going, if you'd have long surrendered if you had trained alone. Some gyms even offer special courses. Most of you will probably be familiar with the ultra-short + ultra-intense HIIT prescription that's known as the Tabata protocol. Not really? Well, here is the elevator pitch, then:  "Tabata training," was first described by the Japanese scientist Izumi Tabata in 1996. Tabata and his colleagues (Tabata.1996) conducted a study that compared moderate-intensity continuous training at 70% of maximal oxygen consumption (VO2max) for 60 minutes, with HIIT conducted at 170% of VO2max. The HIIT training consisted of eight , 20-second all-out exercise bouts followed by 10 seconds of rest for a total of 4 minutes of exercise. Based on what you have read about the contemporary HIIT research here at t...
