    Snowfight Logistics

    This year has turned out to be more hectic than most for many different reasons, most of which have to do with the world outside here. So, while some of you were like: yours truly was more like:

    Nevertheless I did do 412 squats which made me think about the burn. We don't believe in calorie-counting in The Hive but for our purposes here it would be a fun way to work out just how hard you worked while (some of you) iced me.

    The amount of calories a single squat burns depends, of course, on a number of factors some of which I will list here as they are a good reminder about the complexity of physical activity and results:

    - Age
    - Sex
    - Weight
    - Existing muscle mass
    - Rate of execution of squats
    - Time of the day
    - Time of the year
    - Diet
    - Fitness level

    On average however a single squat burns 0.32 calories. So if, you do 412 (like I had to do) you end up using 412 X 0.32 = 132 calories (rounded up).

    See if you can work out your count. Add up all the squats you did, multiply by 0.32 and it will give you an idea (bear in mind it is an approximation for all the reasons mentioned).

    Regardless of the number of snowballs we had to eat, this year's snowfight cheered us up in a year when we are all actively looking for something to feel cheery about. Thanks goes, of course, to you all and I will finish with a warning that come next Christmas I will be devoting some serious time to making sure you all get your just share of ice and snow in a totally round form.

    This was my first snowball fight; it was great fun! I was away from the computer for most of it, however I managed to dodge 91 snowballs = 32 calories. Not much, but I'll take it.

      I dodged 131 snowballs, so that means I burned 42 calories.

      It was my first Snowfight and I'm definitely looking forward to the next. I'm even going to try to more actively take part in it, because I had a lot of fun. Of course, first I need to train up so I can handle (almost ) any amount of snowballs headed my way. A bit of motivation when I get back into DB workouts.

        Well, at least there wasn't thousands of Snowballs flying all over like last year. That would be a huge amount of calories burned!

        Although, out of all the ones I dodged so far, I only did 5 Squats, meaning that I burned 1.6 calories. Thing is I'm at the level in which simple Squats can do only so much, hence I've switched to do almost every single one of those dodges with Single Leg Squats. I don't know if it burns the same amount or not.

        So, 251 x 0.32 = 80.32. That is considering that a Single Leg Squat burns the same amount of calories as a Squat. I would like some help here, please

          Sólveig what an interesting question you pose. All things being equal a single-legged squat should burn the same calories you burn if you perform it with two legs. The reasoning is that when you do a conventional squat the weight of the body is split equally between the two legs and when you perform a single-legged squat one leg carries the entire load you would normally have on two, so nothing changes. But ... that is not really what happens. A two-legged squat balances the body's weight above the pelvis. This then transfers the weight of the body onto the hips, quads and knees. A single legged squat places a higher load on all of these areas, in addition it also activates the core in order to balance the body over one leg. To do so it recruits a lot more muscles than a conventional squat, plus the intensity felt by the quads is higher and intensity is a factor (see "Rate of execution of squats" in my opening post). So, as a rule of thumb you'd burn per single-leg squat, everything you would burn when you do conventional squats plus 10% so each of your squats would be 0.35 calories.

            Well, by the basic maths, I burnt off about 161 calories. BUT - some of my squats were Hindu squats, some were all the way down to the heels, some (but I did four for each count of one to make a whole!) were quarter squats, some were slow, others (when I was in a hurry) were quite pumped out. I guess all those variables would take an awful lot of recalculation, so I'll just stick with, yeah, about 161 cals.

              Damer There's actually more happening than what I expected when you remove one leg from the Squat!

                Damer but aren't the muscles you use for squats in the lower extremeties bigger than the ones above it? And you would therefore use more calories with doing a squat with two legs than one? (Because you can't compensate it with ypur core). And doing double the intensity doesn't necessarily mean that you burn twice the amount of calories.

                (And I know it's just a rough calculation, but I like thought experiments 😇)

                  The physical work is the same, but done by one leg so, one leg is "burning" twice while the other one rests... +what damer said about "balancing and core"...

                    I did shrimp squats with a 36" box jump after it. 😉





















                    ......












                    No, actually, I just did regular squats

                        Hahahahaha, love how the moment we get into the mechanics of anything physical here we're all eager here to take it apart and learn more from it. To add a little more depth to the discussion consider how the energetic cost of any motion is determined by the following:

                        - The size of the muscles engaged (muscles that contain too much collagen, for example, are heavier and bigger but without having a compensatory increase in strength)
                        - The number of muscle fibers engaged each time (what is scientifically called active actin-myosin crossbridges)
                        - The angle of the muscle to the joint from start to finish of motion (the angle is key to determining the force-velocity relationship)
                        - The kinetic chain involved in the motion (activation of the kinetic chain recruits more muscle groups)

                        See what this year's Snowfight started?

                        And NancyTree an increase in intensity without compensatory adaptations increases calorie burn proportionally (up to a point) so, running 100m twice as fast as you did before burns double the amount of energy in the beginning. Once you are proficient by increasing strength, power and joint agility you burn the same as you did before you got to be so good.

                              We are preparing an article on metabolism that I am currently fact-checking that busts a heck of a lot of myths and also will help some things we touched upon in this discussion make a lot more sense. You guys have no idea how awesome you are!
