  • Method for monitoring accumulated body fatigue for determining recovery during exercise or activity
    Patent number: 7192401
    Abstract: The invention relates to a method for determining accumulated body fatigue index (BFI), wherein one or more parameters from the measurement of one or more signals are obtained sequentially as input and these parameters are information on the intensity of physical activity. BFI has a predetermined initial value, and next BFI value is always a sum of BFI-value and a difference. The difference is combination of upslope and optional downslope components of BFI determined with the said parameters and the upslope component and the optional downslope component are each determined with a function, which is scaled by a preset physiological character.

  • Method and apparatus for controlling the atmosphere of an essentially closed space
    Patent number: 5860857
    Abstract: The invention relates to a method for regulating the atmosphere in a substantially closed sports/exercise space (1) or an animal shelter (11), especially in terms of partial oxygen pressure. In the method, the normal atmosphere of said space (1; 11) is admixed with nitrogen for the creation of a desired low-oxygen (oxygen content <appr. 21%) atmosphere, said low-oxygen atmosphere corresponding to partial oxygen pressure in the air at a certain altitude above sea level. Alternatively, said normal atmosphere is admixed with oxygen for the creation of a desired high-oxygen (oxygen content>appr. 21%) atmosphere. Said mixing of nitrogen or oxygen with air is carried out at normal air pressure.
