the energy in the body is produced aerobically, VO2 can be used to determine how much energy a subject is expending. VO2 can be reported in absolute terms (L/min) or relative to body mass (ml/kg*min). Oxygen consumption is dependent on the ability of the heart to pump out blood, the ability of the tissues...
is important to know the differencebetweenaerobic and anaerobicexercises. You are probably asking yourself a couple questions such "Why does this matter?" and "What does each of these terms mean?" When I was present with the two terms, I only knew whataerobicexercises meant to a certain extent...
Aerobic vs Anaerobic
Cardiovascular vs Resistance Training
I've heard the termsaerobic and anaerobic a lot. What do these terms actually mean and are they important for my exercise program?
Strictly speaking, the terms "aerobic" and "anaerobic" refer to the presence and absence...
FQ1: How does training affect performance?
Alactacid system or ATP/PC
Lactic acid system or Anaerobic glycolysis
Aerobic glycolysis system
How it works
After muscular contraction ATP is broken down to form ADP. Phosphocreatine (PC) is then broken down to form creatine and phosphate...
Functional Body Exercise
This is an anaerobic energy system. ATP depletes in about 3 seconds of maximal activity. To continue high intensity exercise recycling of ATP is necessary, however there is insufficient oxygen available to sustain ATP reysnthesis. The body therefore...
1. What are the training goals of athletes?
a. Improving performance
b. Improving specific components of fitness
c. Avoiding injury and overtraining
d. Achieving top performance for selected events (i.e. peaking)
2. What are the long-term and short-term nutritional...

1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition, strength should be assessed using...
What does the term “aerobic” mean? (Not “aerobics”)
Aerobic literally means "living in air",and refers to the use of oxygen to adequately meet energy demands during exercise via aerobicmetabolismWhat are the three factors which can vary to create an increased demand on your threshold of training...
cancer and obesity have become an epidemic and are all associated with the food that we eat. This report will focus on the digestive system and energy metabolism, the guidelines of healthy eating and profile an athlete to analyse his diet to make recommendations for change.
The Human Digestive System
oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers. These chemical reactions produce adenosine triphosphate (ATP) molecules which are used to power the movement of the myosin heads.
The term muscle is derived from the Latin musculus...

METABOLISMMetabolism refers to biochemical processes that occur with any living organism - including humans - to maintain life. These biochemical processes allow us to grow, reproduce, repair damage, and respond to our environment. Most people use the term "metabolism" incorrectly for either anabolism...

information applies to everyone in general; however, not everyone has the same body type. We each have
different responses to exercise depending on our choice of intensity and diet. Before making any changes in
your lifestyle, you should consult with a physician to discover the best...
Physical exercise is any bodily activity that increases or maintains physical fitness and overall health and wellness. It is performed for many reasons such as: strengthening muscles and the cardiovascular system, improving ones athletic skills, weight loss or purely because one enjoys it.
What is exercise:
18. Which of the following is mismatched?
A) I band - contains only actin
B) M line - middle of the H zone
C) Z disk - structure between adjacent sarcomeres
D) myosin myofilaments - thin myofilaments
E) actin myofilaments – thin myofilaments
19. Actin myofilaments
Aerobicexercise (also known as cardio) is physical exercise of relatively low intensity that depends primarily on the aerobic energy -generating process.] Aerobic literally means "living in air", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism...
• To give the overall balanced equations for aerobic respiration and alcoholic fermentation.
• To distinguish between inputs, products, and efficiency of aerobic respiration and those of fermentation.
• Understand the relationship between respiration and photosynthesis.

factoring in that water is composed of 33% oxygen.
Its clear, then, that optimal oxygenation of your cells through proper nutrition, fluid intake, exercise, and stress management is absolutely necessary in order to maintain your health and create a vital life.
