The physiology of training

Tomorrow is Hässelbyloppet and I am at home resting and preparing for tomorrow. It was such a long time ago since I participated in a running event. This will be my third time at Hässelby. I have forgotten how much it is to prepare. Eat right, sleep well, what will the weather be like?  To be honest I have followed SMHI every day this week. Today is rainy and it seems like it will be good tomorrow. I cross my fingers. Actually I have been worried about getting injured so I have to cancel. However, I do a lot of stretch and that prevents a lot.

I am very interested in physiological changes occurring in the body when training. Currently, I read about the heart how it adapts to increased exercise. In brief, it is a lot about how to get sufficient oxygen to the cells that energy can be released so the muscles can work. Here, the heart plays a huge role. To beat so the blood flow can bring oxygen to the muscle cells. It is very interesting that electrical impulses make the heart contract.

Previously, I wrote that my own max puls has decreased. It used to be 200 and now it is 180 when cycling. According to a formula it should decrease with a beat per year so it cannot be age related. Since I have read some (SISU Idrottsböcker) about the changes that can occur in the body when doing exercise it might be a change in balance between the sympathetic and the parasympathetic nervous system. Maybe my vagus nerve is more active. I have also noted a change in max pulse when I run versus cycling. Running is definitely more of a challenge.

It really was a long time ago since I read about the heart and the physiology/pharmacology related to blood pressure and puls. It makes exercise more fun. To measure changes. Now I will spend the rest of this Sathurday correcting my books. I am longing so much for it to be done since I have spent years writing.

    Hi Anna, was looking into perhaps doing Hässelbyloppet next year when I found your blog. It is amazing the good and the bad which training does to your body. I stretch too which helps, also magnesium spray before any run. I was thinking of looking at one of these too but they are kinda expensive http://curemycramp.com/leg-compression-machine/ I hope Hässelbyloppet went well!
