On Monday, Frida Karlsson landed on Swedish soil and then told the skier that she would undergo tests to get an answer on whether she is ready to compete after the less successful efforts at the Olympics.

National team doctor Jan Wall tells SVT Sport that he has had contact with Frida Karlsson during the week.

- We have done examinations and samples and she has felt good.

She has driven at home and thinks it has felt good, he says.

"Rugged desire for revenge"

Due to confidentiality, he does not want to go into details about the tests.

- These are such investigations where we check if you have recovered and that you have no abnormalities.

We do these before the season, during the season and after the season when something is not right.

Now we have done investigations and we do not find anything that would stop her medically, but it is more a "scale situation" where you think about what is smartest.

She is craving revenge and wants to go to Lahti.

What has decided that she can drive?

- It is an overall assessment.

Of course, how the body responds, how she feels.

Should I find something deviating in the samples and examinations, you may need longer rest or treatment that makes you want to wait for start.

Then it's a strategy, there are four World Cup competitions left.

What have you done for evaluation after the Olympics about why she was hit so hard right there and then?

- The main theory from my view is that she was in very good shape at the high altitude camp in Livigno.

She drove a speed pass there which was fantastic.

I think she took out a little too much, wanted too much.

She finished too hard.

It was a tough trip from Livigno to Beijing and the Olympics as well.

It was two days that they flew and then you eat and sleep a little worse.

She then came to Zhangjiakou where it was windy, cold and harsh tracks, it was stressful, he says and continues:

- She also comes in with too much will in the first week.

She is charging too hard.

On days two and four, she runs two hard sessions.

This, together with hard sleep and poorer food intake, means that she does not have time to catch up and ends up a little minus.

Then it will be difficult at high altitude.

She really emptied herself during three races and did not really have time to get to the body she wanted.

She was a little back.

"Not an environment that appeals to Frida"

Do you think that the mental part may have been recorded as well?

- Obvious.

That is an important factor.

there are an incredible number of puzzle pieces that will work for an Olympic medal.

You have to have perfect skis, a body that works and be there mentally perfect.

As we lived there in the Olympic village, it was not an environment that appeals to Frida Karlsson.

She is a social, playful girl who wants things to happen all the time.

Now we were directed to the room and had no meeting points so.

The competitions in Lahti, Finland, will be decided tomorrow, Saturday.
