Abstract

INTRODUCTION
The purpose of this study was to investigate the comparison on body composition, functional fitness and foot pressure balance between props muscle-strengthening and machine muscle-strengthening in older persons.
METHODS
Participants were tested before and after the study to measure body composition, cardiorespiratory fitness, muscular strength, muscular endurance, flexibility, balance, timed Up and Go (TUG) and tandem gait for functional fitness. Also plantar pressure of foot scan for limits of stability test was measured by Biorescue(RM IGENIERIE Co., France) which has % quarterly sector (RF: right front, LF: left front, RB: right back, LB: left back). Fifteen volunteers were randomly divided into two group: Props resistance(PR) training group (n=7,65.29±2.49yrs) and machine resistance(MR) training group(n=8, 63.63±2.32 yrs). Training program were performed for 60minutes per session, 3 sessions per week for 12 weeks. Data were analyzed with ANOVA for repeated measures, t-test using SPSS program.
RESULTS
There were significant difference between period on WHR, 2 minutes walking and stand-up and sit-down from a chair. There were significant difference between group and period on 30 second arm curl, and between group on chair flexibility with straight left leg, 244cm reciprocating walking, tandem gait, stand on left foot with eyes closed, stand on left foot with eyes opened, 4m up and go test show significant difference between period, and stand on right foot with eyes opened show significant interaction. The others variables didn't show significant interaction. The others variables didn't show significant difference between group and period. All of posture stability variables didn't show significant difference between group and period.
CONCLUSION
We suggested that PR and MR training adaptations didn't show significant effects between group and period on almost of body composition variable, but some of muscular strength, coordination and balance show significant effects between period. PR training may be a more easy to use without machine weight facility.
