Ask the Exercise Scientist

[Phate]

Well I would prefer not to talk about AAS related topics since this is not my area expertise unless it is purely physiological in nature, but I think this is a good debate to have.

My thinking on this topic is based on this. A lot of nasty side effects that are reported that are not exaggerated by the media do happen to individuals that have not completely gone through secondary sexual maturity. (puberty)
We all know about the premature fusion of growth plates, increase in acne and this is a big if even in the literature, mood changes.

I take from the literature and not nessicarely my personal feeling on the subject that taking steroids before sexual maturity is probably risky to say the least. The reason I say not my personal feeling is that If I had to do all over again I would have jumped on when I was 18 or 19 because I saw the incredible effects that it had on some of my friends pitching ability. I was about 2 MPH on my fastball from having a shot at a Pro career. Instead now I am a know it all science nerd....LOL

I am not going to sit here and be a hypocrite and say no no no. I will try to interject my reasoning behind it not my personal feelings per say. One thing that is not entirely clear for individuals is the phycological effects it can have on the maturing brain. The Pineal gland of the brain is important gland that facilitates and eventually terminates the process of puberty. Around the late teens to early twenties the Pineal gland is signaled to shut down and it eventually calcifies and because inactive in adults or at least that is what it believed.

The Pineal Gland is an endocrine gland and secretes many different hormones durning childhood. In fact it is quite large in children and very active. Melatonin is one of its major hormones it secretes and is believed to slow the process of puberty. Testosterone or Estrogen is believed to signal the reduced secretion of melatonin thus eventually leading to full sexual development.

Now if you introduce these hormones in large doses typical of steroid cycles. How does this effect the normal maturity and development of the brain and reproductive system. These are all concerns in primary hypogonadism in children receiving hormone treatment. I do not think the literature is entirely clear as a body of evidence, though it is not something I have read up on extensively.

These are just my thoughts on using at an early age and in no way am I implying anything bad can happen my point is these are concerns that need to be thought about by young users.

very good points, i'll have to read up on the physiological effects and propose a counter-argument as right now i do not have enough backing to pose one

Those are different types of second messanger systems. BTW, learning The different RAS messenger system was the damn devil....LOL

You will only ever use that again when you take the MCAT, maybe. Even as a physiologist unless your a protein researcher its useless to know.

I have to admit the chem one was kinda hard for me. I havents seen a reaction without a hundred steps in it in I dont know how long. I am not sure if I got it right or not.....LOL

Yea you got it right...It does suck dude...At least with chem&physics you can memorize the laws and formulas and work them out if you need to. With the BS section of the MCAT all of that stuff must be committed to memory...Most of the physics and chem aspects have no practical use in medicine unless you are doing research, they're merely a tool to weed people out...

Have you took it yet?

[thegodfather]

Hell no...I might not take it until next year, I'm applying to a post-bac program to finish off my sciences that I haven't taken...You can take the MCAT without having all the pre-reqs(which is why i already started studying), you just have to have completed all the pre-reqs by the time of matriculation... What MCAT date and matriculation year are you shooting for?

Oh I am way past all that. I decided to be a research scientist, then when I got done doing my masters I was going to a med school and became clinical exercise physiologist. Then when I was told I was going to be working with 500 rats in a lab, I decided that wasnt for me so now I am doing a different doctorate program. Without giving up to much info about myself...LOL

BTW I got a 28 on MCAT without physics II and Organic II, that was a huge mistake on my part at the time. Organic II was a huge part of the test. I actually had a buddy do the same thing and got like a 34 or 36, something stupidly high like that. From what I hear he is top of his class right now going into his last year I believe.

[MuscleScience]

Oh almost forgot, good luck with your studies. I am sure you will do well on it.

Bump for more questions, you guys have to have something...

[abbot138]

If you have an exercise/physiology related question post it here or in my blog. While I do not profess to know it all I do hold a few advanced degrees and a few research publication in physiology and exercise science related areas.

Thanks.

How much do you know about joint supplements. I have been have issues with the front part of my knee behind my patella. It isn't a sharp pain but more a aching pain that has been affecting my strength squatting/doing quads here recently. It all started once I came off a joint supplement I bought at the health store for 3 weeks then I bought a joint supplement (1500mg of Glucosamine hydrochloride and 1500mg of MSM by Schiff) at the grocery store and it seems to not work at all.

I don't believe I have injuried my self but the issue seems to be unresolved. Is it possible the joint supplement I have now has a bunch of fillers cause I forget what brand I used last time but it was only Glucosamine at it worked like a charm. Or do I need to rest it and take care of it and not hit such heavy weight for a little while. I usually rep 405- for 8-10 reps the past 3 weeks only for 2 and it makes the joint worse.

As I'm reviewing possibilites I'm thinking possible Chondromalacia as my outside quad is much larger than my inside quad and I need to straighten that out

[MuscleScience]

Chondromalacia is my guess also, I had rather bad CM from doing plyometrics all the time when I played ball. To my knowledge about all that can be done is ice therapy and rest. That works for most people, but also a PT program for flexability of the quads and mobilization of the patella along with IT band stretches ect.

As far as the supplementation goes, Glucosamine in its varies forms seems to be beneficial as reported by a few large studies. Usually it is used for the treatment of osteoarthritis, whether it is effective for CM is I think a matter for debate.

Chondromalacia is due to an irritation of the smooth cartilage that is directly under the patella. It is considered a over use condition and it appears that rest is the best treatment for slight to moderate cases.

Thanks for the knowledge. good stuff

Any suggestions on a workout routine. possible lighter weight while squating and feet closer in with fewer sets sound ok??

Gives me a chance to bring up my hamstrings and calves as well so I can look at this as an opportunity...... for now

[Rugger02]

Is Chondromalacia anything like, or related to the condition called Osgood-Schlatter (Not sure if I spelled that right...)
I used to have that in my left knee, and it acted up a lot, got all swollen and hurt real bad...
Ever hear of that?

Osgood Schlatters is one of the very first conditions one learns about if they do anything related to sports and kids, it is fairly common.

Similar in the fact that its caused usually by overuse. However Osgood Schlatters is caused by the patella tendon basically pulling a piece of the tibia apart from the rest of the bone. In children the bone is much more soft and spongy than in adults. The tibial tuberosity is were the patella tendon inserts and anchors itself to the lower leg bone. In active children there is a slow and steady pulling of this tuberosity away from the rest of the tibia. The body tries to fill in the gap by laying down more bone. This can lead to a complete separation of this piece of bone away from the rest of the tibia, this is called and avulsion fracture.

Usually in children the enlarged piece of bone doesnt separate and eventually fills in and calcifies as the child matures. It can in some cases detach completely either from repetitive stress or trauma.

[Rugger02]

Huh, never knew any of that... It was waay worse when I was young. Now there's just a bony bump there. Must be from the calcification or making more bone to compensate for the trauma earlier on. Hardly ever bothers me these days but I can't really get on my knees if I'm on a hard surface, (LOL No gay jokes plz)
Thanks for the info

Now that bump is just a part of the normal bone. The tendon when you were younger was basically tractioning the bone slowely away from the rest of the bone. Now that your an adult you bones are less spongy and have little cartilage content compared to when you were a kid.

why do men have nipples?

[MuscleScience]

why do men have nipples?

Embronically all men have up to six nipples. 4 of the nipples regress as the fetus develops, there is actually still a nipple line in the body. Though you would not be able to see it.

The genes that control breast formation are present in both men and women. The only difference is how the influence of the sex hormones for males and females act on the tissue.

Also the genetic default sex is female. Much to the displeasure of Henry the VIII and more likely Anna Boleyn, the male controls the sex of the offspring by donating the Y chromosome. If for example the Y chromosome is defective or is fragmented the genotype (genetic makeup) will be male but the phenotype (expression of genetic trait) is female.

If the persons DNA was looked at their chromosomes would say they are male but there sexual development would be female.
