When you walk or run, your feet create power by pushing against the ground. This produces movement and pressure that shifts the earth around you.
When you ski, your feet do the same thing, but in a different environment. You are moving your body in a controlled way, but your feet are still producing power to move forward.
The difference is dramatic! When skiing, your feet have to be especially steady as they move on snow. If you have weak ankles or shoes might be too tight for you, then skiing is not for you.
This article will talk about how to make sure your foot health is right for skiing.
The snow exerts a force back on the skier
When the skier is climbing a slope, the snow can contribute some force to his or her motion. This is called static friction and doesn’t occur during dynamic friction, such as when skier glides down a hill.
Static friction happens at very low speeds, usually when an athlete is running or riding a bicycle. It occurs when a piece of cloth, foam, or metal that is wrapped around an object is in contact with another object.
When the skier is moving, he or she still has static friction with the snow. When the skier is climbing or skiing, it occurs at higher speeds where there’s more motion involved.
The skier is slowed down by the snow
When a skier is sliding down a slope, the amount of time they are spending on each pass depends on the slope.
Some slopes require no effort at all to maintain a steady slide. These include grassy slopes and ones with very little texture, like snow floors.
Other slopes require a little work- but- worth for a progressive reward. This includes snowy surfaces, such as pavement or gravel.
The skier must choose which reward to give him/herself during each pass. The variation in reward gives the skier motivation to keep going, which is one of the main features of this transformation app.
The skier speeds up the snow
When the skier is climbing a slope, his or her body is going along a normal path. The snow is being used at a constant rate, so there are constant changes in the skier’s body.
The muscles have to work to maintain the same elevation of the snow. This requires more energy in the form of extra calories and/or fat.
Once the skier reaches his or her desired elevation, he or she can ease up the speed and start descending at a slower pace. This is when the energy transformation takes place!
This happens because as you climb, you may have used more energy than if you were skiing at a slower pace.
The skier transfers their energy to the snow
When you ride a bike or walk, you are transferring your force and weight to the snow. The same happens when you ski or walk in the snow.
Skiers transfer some of their power to the snow to glide. This is like cycling or walking with your hands on a dashboard. Theres a force and an effect that happen together.
When you ski at high speed, if you are carrying heavy objects, then your energy must be really powerful!
How much energy you need depends on how much weight you are carrying and what kind of object you are carrying.
The snow transfers its energy to the skier
When a skier is sliding at a consistent speed, the snow is being re-apped of its energy. This happens because the skier is using movement to transfer the motion to the snow.
When the skier stops moving, the snow starts coning. This happens because when a piece of energy moves at a constant speed, like ice does, it takes double the time for it to change color.
Cones take longer to change so when a skier stops sliding, he or she has to wait for them to turn white before starting again. This improves his or her chances of landing that perfect slide!
Blasting down hills or slides can be important on keeping your energy up.
All of the above
When we talk about energy transformation, there are a few different things that happen. We refer to them as the above categories.
Those things we refer to as the all of the above category include:
the change in work or activity performed by an individual, including how quickly they perform that activity;
the change in oxygen levels in the blood or breath of individuals during or after an activity; and,
the increase or decrease in energy levels of an individual during or after an activity.
There’s a good chance one or more of these occurs during exercise, and although it may sound scientific, you might not know for sure until you try it.
