| Abstract |
This study aimed to develop a prediction equation of physical fitness age (PFA) using fitness and morphological factors as independent variables. A total of 3,553 men (29.3±11.1 yrs) and 3,467 women (37.5±13.7 yrs) aged 10-65 were included. Physical fitness variables were maximal aerobic endurance, muscular endurance, muscular strength, power, agility, balance, and flexibility. The regression model by sex showed as; PFA=61.762+(0.162*back strength)-(0.257*jump height)-(0.330*curl up)+(0.287*grip strength)-(0.237*height)-(0.15*sit-
&-reach)+(0.128*maximal oxygen uptake)+(0.006*reaction time)-(0.045*weight)-(0.011*balance eye closed) for men
(R2=0.313), and PFA=102.157-(0.272*jump height)+(0.264*back strength)-(0.377*height)-(0.44*curl up)-(0.164*grip strength)-(0.157*maximal oxygen uptake)-(0.006*reaction time)+(0.078*sit-&-reach) for women (R2=0.479). These equations can be adopted for individualized exercise program and prescription. |
