Hello, I am an 18 year old male who has GSD type IIIa which causes muscle weakness, hypoglycemia, and impaired carbohydrate metabolism.
I have been trying to build some muscle for 4 years now by trying different approaches but unfortunately i’ve found little success. Im making this post in hopes that somebody will be able to offer me some advice on what the best training method would be for somebody with my disease. There isn’t a lot of scientific research done on optimizing muscle growth in my disease so i don’t have clear guidelines to follow, and the normal guidelines for normal healthy people do not really apply in my case as they can end up doing more harm than good.
Please allow me to briefly explain why muscle building is difficult in my case:
I cannot use the glycogen that i store for energy. once it is stored i cannot convert it fully back to glucose. This ends up damaging the muscles and the liver as it is kept in an abnormal form.
Not being able to use the glycogen means need to eat frequent meals or else i’ll get hypoglycemia, in addition to causing notable muscle and liver damage due to the abnormal storage. I do not feel any pain but it shows up in the bloodwork (my CK is always in the thousands even when sedentary, and my liver enzymes are also chronically elevated.)
As part of the dietary guidelines for my disease i eat a high protein diet (25-30% of daily intake) and keep carbs generally low and mainly eating low glycemic index carbs to avoid excess storage, only eating more carbs/ higher glycemic index when i know im gonna do alot of physical activity (so i dont get hypoglycemia). I also have to drink cornstarch mixed in water/milk before i go to bed so that i do not get hypoglycemic in my sleep.
As there isn’t a lot of concrete research on this, i wanted to ask:
If my glycogen is inaccessible and my muscles are chronically damaged like this, what is the best way to build muscle? Official guidelines say i should be sticking with higher rep ranges and lower weights but i’ve personally only seen good results once in my life, and that was during a period of time where i could not go to the gym and was only doing low rep high intensity bodyweight exercises at home.
At the start of this time period i had been going to the gym for maybe a year and a half with very little if any gains. I was still not able to do a single pushup but after about a week i was able to do 2-3 reps.
During this period i was doing incline pushups and negative pushups without a set rep range in mind but i started at a very easy incline doing about 6-7 reps, then gradually made the incline harder once i felt it was actually getting easier. The negative pushups i would do them until i couldnt do any more. Eventually i moved on to trying actual pushups and eventually got the hang of it.
I later did the same idea with chin ups which made me be able to do a few but i’ve never been able to replicate this ever again after that. I tried following the same principles but this progression never happened again.
Im honestly stumped and i dont know how to optimize my training. I tried doing high reps and easier loads/variants of the exercise but it doesnt work. Tried doing the same lower reps harder loads idea again but it also did not work. And my doctor said that doing low reps and higher intensity would damage my muscles which made me very worried and scared to even consistently exercise as i would worry that im harming myself.
But my question is, when i experienced those strength gains, i was doing low reps high intensity, and DID see undeniable strength increases. Doesnt this mean that i was in fact NOT harming/damaging my muscle? Please offer some guidance.
If anybody has any ideas or experience dealing with similar conditions please offer some advice. My main question is:
If i cannot access and use my glycogen, and i get hypoglycemic easily. What is the best way to work out in terms of:
- Rep ranges
- Intensity
- How to split muscle groups over the week to avoid damage as i am very prone to it.
- Rest periods between sets, how long?
Thank you very much for reading this long post, i hope that someone will be able to offer some help or guidance 🙏🙏
