On to chapter 2!

Chapter 2: Within this chapter, you do need to take away some of the key points in exercise physiology. 


This includes the fitness components,

  • Muscular Strength- This is the maximum force that a muscle or muscle group can exert during a contraction. Just yesterday, I realized that I finally had the muscular strength to close the lid on my GNC shaker bottle! Why is that thing so difficult to close?       This also includes Muscular Endurance. Reps! How many reps can you do before before that muscle is fatigued? The other day I did 100 push-ups to complete the "Century Push" quest on http://www.fitocracy.com. I never would have attempted such a feat without that extra motivation. Fitocracy is awesome. 
  • Cardiorespiratory Endurance- The better your  cardiorespiratory endurance, the more physical work you can do before becoming fatigued. Feel like you are going to die after 30 seconds on the treadmill? You need to work on your cardiorespiratory endurance.
  • Flexibility- The ability to move joints through their normal range of motion (ROM).
  • Body Composition- Proportion of lean body mass and body fat. Fat is not just for fat people. Skinny bitches can also be "fat" by having crappy body composition.



 when each energy system is used, 



  • Stored ATP- Can be used immediately, but quantities are very limited. Like only last a few seconds limited.
  • The Phosphagen System- Quickly creates ATP from the breakdown of Creatine Phosphate (CP). Quantities are still limited. Good for short-term, high intensity activities. Last about 10 seconds.
  • Anaerobic Production of ATP from Carbohydrate (Anaerobic Glycolysis)- Lasts about 3 minutes during high-intensity activities.
  • Aerobic Glycolysis- Used for sustained activities.

ventilatory threshold


  • The point of transition from Aerobic energy production to Anaerobic energy production.

exercising in the heat and cold


Heat

  • Take time to acclimate to the heat. Increase duration over 7-10 days.
  • Don't overdress. No parkas if it's over 80 degrees.
  • Don't wear one of those stupid sauna suits. You look like an idiot running around in a black trash bag. 
  • Drink small amounts regularly.

Cold

  • Dress in layers
  • Don't get so sweaty that you clothes are dripping wet. Wear ventilated clothing.
  • Cotton bad. Wool, poly fleece, and Gore Tex Good.
  • You still need to stay hydrated. You loose a lot of fluid breathing in cold air.

and an understanding of the environmental considerations.

  • High Altitude- Take time to acclimate to the altitude, as it is more difficult to get enough oxygen at higher altitudes.
  • Air Pollution- Exercise early in the morning before there is a ton of car exhaust in the air. Work out indoors when air quality is especially bad.

Too much information.

The Essentials of Exercise Science is the OTHER book used when studying for the ACE GFI test. The first time I cracked it open, I seriously had second thoughts about this whole certification thing. There is just no way my brain will ever retain all this information. The anatomy section is the killer for me. I just SUCK at memorization. I mean SUCK! It doesn't help that all the muscle names are 500 letters long.

ACE actually has a blog with tips for people studying for their exams. This post saved my sanity. It's also nice to know I'm not the only one feeling like a friggin' genius, trying to memorize the names of muscles they can't even spell. The post lists exactly what we need to know from each chapter. THANK YOU!

Lets start at the beginning:

Chapter 1: The most important aspects of this chapter are the anatomical positions

  • Anterior: Toward the front
  • Posterior: Toward the back 
  • Inferior: Away from the head
  • Medial: Toward the midline of the body
  • Lateral: Away from the midline of the body
  • Proximal: Toward the attached end of the limb
  • Distal: Away from the attached end of the limb




  • Sagittal: Vertical, Divides left from right.
  • Frontal: Vertical, Divides front from back.
  • Transverse: Horizontal, Divides top from bottom.



 the segmental movements in the three planes;

Sagittal:
  • Flexion
  • Extension
  • Dorsiflextion
  • Plantarflexion


Frontal:
  • Abduction
  • Adduction
  • Elevation
  • Depression
  • Inversion
  • Eversion


Transverse:
  • Rotation
  • Supination
  • Horizontal Flexion
  • Horizontal Extension



So that's it. Easy, right...lol...
