sloshing water: effect on energy/effort
Posted: Mon 19 Aug, 2019 9:04 pm
This is a bit of a side diversion to the below soft water bottle topic. Possibly belongs in techno babble.
I commonly use 2 x 1 L PET bottles. I couldn’t find two cheap 1L ones last time i visited the super market, so grabbed 2x 1.5L.
Typically, I fill with around 500ml each (and occasionally 1L each if it’s a big day with no resup points)
On my osprey pack I have these in the side pockets on a angle. With 500ml of water and 1.5L bottles I very much noticed the slosh effect.. the water bouncing and water weight shifting back and forwards as I moved.
And I wonder if this sloshing is causing me to use up more energy... either through my muscles needing to stabilise the load more or because the water sloshing backwards is energy heading in the reverse of my walking direction..
Thoughts?
(its not something I’m overly concerned about... more scientifically curious)
