This study measured body composition and muscular strength, to examine their relationship, using the Bioelectrical Impedance (IB) method and biodex system3, respectively, in 44 healthy male(20) and female(24) university students. 1. Muscular strength of the upper extremities correlated significantly with fat-free mass(FFM) with $r=.604{\sim}.630$ and intracellular fluid(ICF) with $r=.672{\sim}.668$ in males and FFM with $r=.416{\sim}.552$, ICF with $r=.432{\sim}.564$ and extracellular fluid(ECF) with $r=.429{\sim}.463$ in females. 2. Muscular strength of the lower extremities correlated significantly with FFM with $r=.522{\sim}.785$, ICF with $r=.501{\sim}.739$ and ECF with $r=.498{\sim}.796$ in males and FFM with $r=.642{\sim}.660$, ICF with $r=.627{\sim}.671$ and ECF with $r=.572{\sim}.623$ in females. 3. Muscular strength of the trunk correlated with FFM with $r=.595$, ICF with $r=.627$, ECF with $r=.448$ in males, but did not correlate significantly with body composition in females. These results suggest that total body water(TBW) and ICF may be factors directly associated with muscular strength as well as physical fitness.
