To this end measurements were made of K absorption tissue K content plasma K levels fecal and urinary K excretion during and after hypokinesia HK with and without K supplementation. Studies conducted on male Wistar rats during a pre-hypokinetic period a hypokinetic period and a post-hypokinetic hperiod. Rats were equally divided into four groups unsupplemented vivarium control rats UVCR unsupplemented ypokinetic rats UHKR supplemented vivarium control rats SVCR and supplemented hypokinetic rats SHKR . SHKR and UHKR were kept in small individual cages which restricted their movements in all directions without hindering food and water consumption. SVCR and UVCR were housed in individual cages under vivarium control conditions. SVCR and SHKR consume daily mEq potassium chloride KCl per day. Absorption of K and K levels in bone muscle plasma urine and feces and PA levels did not change in SVCR and UVCR compared with their pre-HK levels. During HK plasma fecal and urinary K levels and plasma aldosterone PA levels increased significantly p with time while K absorption muscle and bone K content decreased significantly p
