Do you like hearing the good news or bad news first?
Me, I like to hear the bad news first. Get it out of the way and hope the good news cheers me up. Plus if I heard the good news first, then the bad, the bad would bring me down. This is important stuff here.
So… my bad news. I’m already behind in my studying! Section 1 took me 3 extra days.
I don’t have much extra time to be behind.
The good news. I think I can easily get caught up + ahead during my vacation. Plus I am loving every minutes of this, so that makes it easier. That’s good news!
Here are a few of the important items I’ve been learning about so far in section 1.
Essentials of Exercise
Exercise offers so many health benefits. Just a few are…
- Lowered risk of stoke, type 2 diabetes, high blood pressure, coronary heart disease and breast cancer
- Improved cardio respiratory + muscular fitness
- Prevention of weight gain
- Reduced depression
What happens to the body when you start exercising…
- Increased blood flow
- Increased oxygen delivery + carbon dioxide removal
- Increased oxygen uptake to muscles and aerobic power
The 3 types of energy systems our bodies use…
- ATP – lasts 1-15 seconds – fuel source is creatine phosphate
- Lactic acid system – lasts 45-90 seconds – fuel source is carbohydrates only
- Aerobic system – lasts 3 minutes or longer – fuel source is carbohydrates, fat and protein
About the body…
- Anatomical terms
- Planes dividing the body: horizontal, sagittal, frontal
- Joint actions: flexion, extension, adbuction, adduction, rotation, circumduction
- Muscle terms: agonist, antagonist, primary movers, assistors, stabilizers
- Muscular contractions: isometric, concentric, eccentric (most common 3) plus isotonic and isokinetic
- Muscle fibers: fast and slow twitch
- Postural deviations: scoliosis (curve in the spine), kyphosis (very rounded shoulders), lordosis (excessive low back curve)
There’s a lot more to learn about the body… major muscle groups will be a huge section.
Let me know if you have any questions about anything I’m learning. I’d love to answer your question.
