Use of carbon dioxide supplying means for muscle strengthening and method of increasing cattle meat thereby

Abstract

Use of a carbon dioxide-supplying means for muscle strengthening makes it possible conveniently to strengthen a target muscle within a short period of time merely by allowing the target site to absorb carbon dioxide without loading any mechanical burden on the target muscle. By loading a mechanical burden on the target muscle, the muscle strengthening effect can be further enhanced and an additional effect of promoting the recovery from muscle fatigue can be achieved owing to the mechanical burden. By using the carbon dioxide-supplying means for muscle strengthening as described above, it is also possible to increase cattle meat.

1 . A muscle strengthening agent or a muscle strength decrease inhibitor comprising carbon dioxide as an active ingredient, in which carbon dioxide is transdermally administrated at a target site. 
     
     
         2 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 1 , selected from the group of gaseous carbon dioxide, a carbon dioxide agent for external use, a carbonated spring and water vapor containing carbon dioxide. 
     
     
         3 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 1 , selected from the group of gaseous carbon dioxide and water vapor containing carbon dioxide. 
     
     
         4 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 3 , wherein carbon dioxide is administrated with a carbon dioxide external administration device characterized by comprising a sealing enclosure member capable of sealing a body surface from the outside air, a supply means for supplying carbon dioxide into the inside of the sealing enclosure member, and an absorption aid comprised of a viscous material containing a thickener and water which assists transdermal or transmucosal absorption of the carbon dioxide inside the sealing enclosure member. 
     
     
         5 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 4 , wherein the thickener is selected from sodium alginate and sodium carboxymethylcellulose. 
     
     
         6 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 1 , selected from the group of gaseous carbon dioxide and a carbon dioxide agent for external use. 
     
     
         7 . The muscle strengthening agent or a muscle strength decrease inhibitor according to  claim 6 , wherein the concentration of carbon dioxide is equal to or over 300 ppm. 
     
     
         8 . A kit comprising two or more of an agent or an inhibitor selected from the muscle strengthening agent or the muscle strength decrease inhibitor according to any of  claims 1 - 7 .
