Method: There&apos;&apos;re 22 senior participants ( average age 73.5±6.5 years , height 155.6 ±10 cm, weight 57.3±11.3 kg) joining the resistance training. Body composition and functional physical fitness will be measured respectively on the 4th, 8th, and 12th week. The items of body composition includes body mass index (BMI), muscle mass, and bone mineral density(BMD). And the items of functional physical fitness includes upper body muscle strength (30-second arm curl test), lower body muscle strength (30-second chair stand test), body flexibility (chair sit and reach test), static balance (the one leg with eyes opened or closed), dynamic balance (8-feet up and go test). The 4-time results will be analysed by repeated measures one-way ANOVA analysis. If there is a significant difference, LDS will be used for post hoc comparison. The level of significance is α=.05. Results: As for the Body composition, after training the fourth, eighth and twelfth weeks of BMI, and after training the fourth and twelfth weeks of BMD were significantly lower than before training (p<.05), But the muscle mass before and after training, while no significant differences (p>.05). As for the functional physical fitness, Training Fourth, eighth and twelfth weeks of upper body muscle strength, body flexibility, and dynamic balance ability were significantly better than before training (p<.05); after training the eighth and twelfth weeks of static balance (the one leg with eyes opened) and lower body muscle strength were significantly better than before training (p<.05). Static balance(the one leg with eyes closed) was no significant difference (p>.05) between before and after training. Conclusion: Resistance training not only improve BMI and BMD of older adults but also enhance the upper body muscle strength, lower body muscle strength, body flexibility, static balance (the one leg with eyes opened), and dynamic balance. Especially in BMI ,BMD, upper body muscle strength, body flexibility, and dynamic balance ability, four weeks of resistance training improved effectively.
