I grew taller from sprinting, but now I can't get the same response

I got into height maximization a while back. After researching it, I started playing basketball and sprinting around the same time. When I first started, I was very consistent with basketball. For around two to two and a half years, I was playing about three times a week.

During that same period, I also started sprinting multiple times, then stopped, then came back to sprinting again. Over those two to two and a half years, I probably stopped and restarted sprinting five, six, or even seven times.

Every time I came back to sprinting during those first couple of years, my body seemed to react the same way. I could get that intense sprinting feeling again, even after taking a break. So, for almost the entire first two to two and a half years, whenever I stopped sprinting and eventually started again, everything felt normal. My body reacted strongly to the training again.

But after around two to two and a half years of this overall training, something changed. The last time I came back to sprinting, it wasn't normal anymore. Even on the first day back, I didn't get the feeling I used to get. That was very strange to me because every other time I stopped and came back, the feeling would return normally.

That's why I'm wondering if the way I trained for those two to two and a half years somehow affected how quickly my body adapts to sprinting, or if I'm misunderstanding how adaptation works.

When I sprint really hard, I get extremely heavy breathing, a burning or tight feeling in my chest. Sometimes a little pain in my chest, and sometimes a strong feeling like I'm going to throw up. It feels like my body can't keep up with the sprint. Then when I finish the reps, the feeling can become so intense that it makes me sit down. Sometimes I feel like I can't keep standing properly for a moment because I'm completely exhausted.

I'm not talking about just being tired after exercise. I'm talking about that extreme feeling I used to get when I pushed myself really hard. I used to associate that feeling with very high intensity, lactate, metabolic stress, and possibly a stronger HGH response.

These are the things that make me feel sure that my body is giving a massive HGH response after sprinting:

One is what I think are growing pains. Sometimes in the middle of the night when I wake up, or in the morning, I feel aching or pain around my knees, ankles, or even my spine. I notice this more during periods when I feel like I'm growing.

Another is deep sleep. After sprinting, I sometimes get much deeper sleep than normal.

Another thing I notice is acne. I normally don't have acne, but especially after sprinting, I can get an acne breakout. Sometimes I can sprint in the morning with clear skin, and later that same day, within around 12 hours, I notice acne appearing or getting worse.

When I first started sprinting, I also noticed a strong feeling of tiredness throughout the entire day after exercising. It wasn't just normal tiredness from working out. I would feel tired for basically the whole day.

I also noticed that my nails and hair were growing really fast.

These are the things I personally notice after sprinting. I feel like they're connected to how my body responds to exercise. I know these things don't automatically prove how much HGH I'm getting, but I'm mentioning them because they're things I've noticed repeatedly.

After 6 to 7 months of no sprinting, as I told you, I still didn't feel the sprinting the way I used to. Then someone told me to switch up the sprint type, so I started doing sprints on flat ground, going back and forth 4 times without stopping. I kinda got that sprinting feeling back and started growing taller again. But after doing this for 3 to 4 months, the sprinting feeling gradually disappeared again. And my height growth stopped. That's where I'm at now.

At one point, someone told me that if I train too much, like sprinting around three times a week the way I was, my body could get used to it and eventually stop producing HGH the same way. Because of that, they told me to sprint only once a week so my body wouldn't adapt as quickly. So I've been doing sprinting once a week until now. Because I don't want my body to adapt.

But I'm still having the same problem. I feel like my body has stopped giving me that strong response, and I also stopped seeing the height growth that I was noticing before. This is what confuses me the most.

I changed from training multiple times a week to once a week because I was told that would prevent my body from adapting, but I still don't get the old feeling or the results I felt like I was getting before.

I also tried changing the workout. Someone suggested doing 60 yard sprints, turning around and sprinting back, repeating that four times without stopping, and then doing multiple sets. I eventually increased it from four rounds to eight rounds and even did five sets. I thought increasing the volume would bring the old feeling back, but it didn't.

So now I'm really confused. So I want to ask you guys a few things.

● What do you think about my first two to two and a half years of training basketball and how my body reacted to it? Could doing this type of training consistently for two to two and a half years have made my body highly adapted to this type of exercise? Could the way I trained during those years be the reason that my body now adapts so quickly, even when I take a break? Or do you think I'm misunderstanding how adaptation works? I want to hear from the one who has the right knowledge about this right now.

● How can I get that old sprinting feeling back? I'm specifically talking about the extreme heavy breathing and that feeling of pushing myself really hard. What should I change to create a different training stimulus? Distance, rest time, hills versus flat ground, sprint structure, recovery, or something else?

If anyone here knows a lot about sprinting, lactate threshold, metabolic stress, HGH responses, or is an athlete with experience in this area, I would really appreciate your advice. And if you have friends who are serious athletes or know about lactate adaptation or HGH responses, you can ask them too.

There are also two things I heard about from other people that made me think about this problem.

The first one is a basketball player. I forgot his name, but I heard that he was doing something like two hours of sprinting to get HGH, and I also heard that he actually grew taller from doing this. When I heard about that, I started thinking that maybe he was doing so much sprinting because he was facing the same problem I'm facing, where normal sprinting wasn't giving him the response he wanted, so he had to do more.

The second thing I heard was from someone who said that sprinting didn't work for them, so they were doing around 20 miles of cycling to get an HGH response instead. They said sprinting didn't really do anything for their body, which is similar to what I'm experiencing.

So these are two people I heard about, and I'm wondering if their experiences could be related to the problem I'm having.
