MUSCLES By Nenad Rodic, posted 04/05

Muscles can be considered the engine of exercise, as they make all the movement possible. Human body is equipped with three different types of muscle fibers: smooth (most internal organs are built from these fibers); cardiac (specific to the heart only); and skeletal (they connect and move various bones in the body). It is this third group that is the focus of our interest and discussion...

CIRCULATORY AND RESPIRATORY SYSTEM By Nenad Rodic, posted 04/05

Circulatory system transports blood throughout the body. It is made up of the heart and the blood vessels (veins, arteries, capillaries). Blood carries oxygen and nutrients to all organs and cells ...

OXYGEN CONSUMTION AND EXERCISE By Nenad Rodic, 04/05

The amount of oxygen used by muscles is directly proportional to the intensity of exercise until the maximum heart rate is reached...

ENERGY METABOLISM AND EXERCISE By Nenad Rodic, posted 04/05

The process of energy supply, exchange and conversion within the body is referred to as metabolism. It is the understanding of metabolism that is largely responsible for the advances in training methodology. ...

HORMONAL RESPONSE DURING EXERCISE By Nenad Rodic, posted 04/05

Hormones are substances produced in the endocrine glands. They are secreted directly into the blood. Blood delivers hormones to all tissues where they are received by the specific receptors.

PERFORMANCE RELATED BENEFITS OF TRAINING By Nenad Rodic, posted 04/05

As we explained earlier through glycolysis pyruvate will combine with H ions unless they are reduced through aerobic metabolism. Naturally, the most beneficial aspect of training is the increased oxygen consumption. Oxygen consumption is the main theme of every page we presented at this site but let us summarize.

BASIC TRAINING PRINCIPLES AND PARAMETERS By Nenad Rodic, posted 04/05

ADAPTATION
The term adaptation refers to changes the body goes through in response to training. This happens when organs and tissues operate on a higher level than usual.

RECOVERY AND OVERTRAINING By Nenad Rodic, posted 04/05

It is safe to say that your triathlon training will lower or deplete glycogen stores in your body. Even if one workout does not do it, five or six consecutive days of training will lower the levels of glycogen to the point when any serious workout is almost impossible. That is why most programs insist on easy days or days off.

PSYCHOLOGY OF TRAINING AND RACING By Nenad Rodic posted 04/05

We have all heard claims that racing is 90% mental and 10% physical. While I may not agree with this, I would have to admit that getting to the race is 100% mental. Everything we do in our lives, and this includes training, is driven by some impulse, some wish, some thought, but in and of itself, a single thought or a random desire is not enough, of course.
