Another class down this week: Massage. While at first it was fun to get massages, the novelty died-off very fast. I ended up dreading this class every week because it was very long (4 hours) and a bit boring (lather hands with oil, massage body, repeat). *Fingers crossed that my massage practical exam goes well in two weeks' time*.
In other news... here are some random facts from the week:
- Some products that are labeled as trans-fat free may actually have trans-fat in them. Legally, if a product has below 0.5 grams of trans-fat, this value can be rounded down to 0.0 and the product can be labeled as "trans-fat free". Note: trans-fat is one of the unhealthiest fats.
- Xylitol is alcohol that tastes sweet. Next time you eat a processed sugary food, check out the label for this ingredient. Although it tastes like sugar, it is digested and metabolized differently in the body.
- Nutrients are described as essential constituents in the diet that are needed to maintain body functioning and to maximize activity.
- A Calorie (with a capital "C") is described as the amount of energy required to heat 1 gram of water up by 10 degrees Celcius. This amount of energy is equivalent to 4.1868 J (i.e. Joules, a unit of energy).
- Bioelectric impedance analysis is a technique used to determines the percentage of fat in the body. It measures the resistance confronted by a small electrical current that is passes through the body. The theory is that since muscle has a higher water content than fat, muscle is more conductive of energy. The easier the current is able to pass through the body, the less fat there is present in the body.
Wow--- that electrical impulse and fat non-conductivity makes sense. It has been my observation that people more "in shape" with less obvious body fat, more often notice static electricity in things like carpet and door handles... Mama M
ReplyDeleteReally? That is pretty cool. I will have to ask my super buff friends if they notice this :P

ReplyDelete"Massage? Done!"
ReplyDeleteOK, Vince! ;)
By the way, I am pretty sure that a calorie is the amount of energy needed to heat 1 gram of water by __1__ degree Celsius.
...but we should be dumping non-metric units, anyway. Long live the joule!
You're right! It was a typo. 1 gram of water by 1 degree Celsius.
ReplyDeleteMassage = DONE! (Ha).
