The Purpose of this study was to investigate the influence of percent of Body Fat on Back Muscle Strength 150 Subjects(50=Physical Education department Students, (=P.E.D.S.), 50=General Students(=G.S), 50=Excellent Players (=E.P)) were Selected to measure the percent of Body fat at the Subscapular and Thigh with a skinfolder. Percent of Body fat was then Calculated with Sloan & Wire's formula and Brozek, et als formula.
The Back Muscle Strength was Calculated through investigating the difference between the percent of Body fat and Static Back muscle Strength among the 3 groups.
The results of this study are as follows:
1) The difference of Mean of Percent of Body fat,
(1) There are significant differences among the 3 groups.
(P<0.05, G.S., E.P., P.E.D.S.)
(2) There is a Significant difference between G.S. and P.E.D.S.
(P<0.01, G.S., P.E.D.S.)
(3) There is no Significant difference between the P.E.D.S. and E.P.
(P>0.05)
(4) There is a Significant difference between the G.S. and E.P.
(P <0.05, G.S., E.P.)
:2) The difference of Means of Back Muscle Strength,
(1) There are significant differences among the 3 groups
(P<0.01, E.P., P.E.D.S., G.S.)
(2) There is a significant difference between the G.S. and P.E.D.S.
(P<0.01, P.E.D.S., G.S.)
(3) There is a significant difference between the P. E. D. S. and E.P.
(P<0.01, P.E.D.S., E.P.)
(4) There is a high significant difference between the G.S. and E.P.
(P<0.01, G.S., E.P.)
3) The correlation between the Back Muscle Strength and Weight,
(1) There is no correlation in the G.S. (r=0.10)
(2) There is a little correlation in the P.E.D.S. (r=0.23)
(3) There is a high significant correlation in the E.P. (r=0.91)
4) The correlation between the Back Muscle Strength and Lean Body Weight
(1) There is a small Negative Correlation in the G.S. (r=-0.22)
(2) There is a negation Correlation in the P.E.D.S. (r=-0.32)
(3) There is a significant positive correlation in the E.P. (r=0. 55)
