Steroids and Your Blood (Part 1)

By Mick Hart

Even a weight trainer engaged in heavy lifting will return out of the norm results even with no use of anabolic steroids. Now we all know the liver is one of the most important organs in the body Duh! - they all are! Detoxification, numerous processes involved in the conversion of food for energy, growth and repair.

The secretions aid fat digestion producing high density lipoprotein Cholesterol (HDL-C) and destroying the undesirable low density lipoprotein Cholesterol (LDL-C). Did you know that even when we are resting, that our liver receives about 30% of our blood supply? You have a good look at the meat counter the next time you go to the supermarket.

Liver function tests actually detect enzyme levels (biological catalyst, want to know more? - go do a biochemistry course). A weight trainer's intense workouts will break down large amounts of skeletal muscle cells (if you've been working out properly anyway).

Not only this but also intra muscular injections will reveal that test results are misleading. So what exact information does our Doctor need for us to get the correct medical advice that will help to make our muscles bigger? The actual tests themselves include a number of enzyme markers but I would like to pay most attention to the ones relevant to bodybuilders.

All of the following are parameters measured in a full blood haematology profile, I include it here for completeness sake, but in reality only a few of the indices are of interest to us as weight trainers.

Haemoglobin: Let's take a look at the quantity of major blood protein of red blood cells and we certainly don't want a low count test result as this would imply that you have anaemia. The more likely causes are unbalanced diet and or deficiency of Vit B12 and folic acid in the blood. But no sweat, this is easily put right with a nice helping of liver or spinach.

Red cells: weird one, measures the amount of red cells in a given volume of blood. These are produced by the bone marrow and survive for around 3 weeks, certain toxins namely alcohol can result in larger than normal cells (macrocytosis) - problem if you're trying to squeeze the fat arse cells through small capillaries!

HCT ratio PCV (haematocrit ratio, packed cell volume / MCH (mean corpuscular haemoglobin / MCHC (mean corpuscular haemoglobin concentrations) - are all red cell indices describing the shape and content of red blood cells.

ESR (erythrocyte sedimentation rate) shows us the state of a patient's health. The rate can be compromised by infection through certain medications that are prescribed which weaken the immune system. Another cause for a high test rate could be through the cause of an inflammatory condition.

Platelets; represents the average number in a given volume of blood, and are essential for helping blood to clot (a low count could lead to bruising or prolonged bleeding from a wound). Use of Aspirin in an ECA stack can also exacerbate this!

White cell count can indicate viral or bacterial infection as this test result would rise with an infection as white cells increase and produce antibodies to combat infection (this is also a good reason to have good muscle mass - where did you think the protein to synthesis antibodies came from?)

The above tests are not normally looked at in the GP's consulting room, unless specific problems have been encountered. The following test parameters are the ones that are usual to weight trainers but sound alarm bells to any consulting Doctor interpreting the results, not used to having a 200lb plus muscle monster in front of him. (Don't miss part 2).
