Purpose: The purpose of this study was to evaluate the influence of senior functional fitness and agility ability on the different risk of sarcopenia female older adults Methods: Ninety-eight community-dwelling female adults aged over 65 (age: 74 38±6 95yrs BMI: 3 28±3 98kg/m2) were divided into two parts as a group by risks of sarcopenia according to different research topics using the SMI handgrip and gait speed cut-off point by Asian Working Group for Sarcopenia 2 (AWGS2) (1) sarcopenia combine functional risk: no risk group (NRG n=28) low sarcopenia risk and low functional group (LRF n=18) low functional risk and low muscle mass group (LRM n=24) and sarcopenia high-risk groups (HRG n=28) (2) The number of sarcopenia items: no any risk group (NR n=29) low sarcopenia risk (LR n=31) medium sarcopenia risk (MR n=22) sarcopenia high-risk groups (HR n=28) Upper extremity muscle endurance (30-second arm curl lower extremity muscle endurance (30-second chair stand ) upper extremity flexibility (back scratch) lower extremity flexibility (chair sit-and-reach) dynamic balance (8-foot up-and-go) static balance (single-leg stand ) cardiopulmonary fitness (two minutes step) reaction time (whole-body reaction Vienna test system) balance ability (Biosway) were evaluated One-way ANCOVA was used to determine differences between groups Pearson’s product-moment correlation was used to determine the correlation between muscle mass functional fitness and agility ability Stepwise regression was used to determine the factor of sarcopenia risk item Results: In part 1: SMI were significantly positive correlations with a handgrip 30-second arm curl and balance of lower extremity(p< 05) Handgrip 30-second arm curl and eyes closed firm surface had significant positive correlations with both SMI and upper extremity muscle mass Handgrip was also had significant positive correlations with lower extremity muscle mass The NRG group showed significantly better than LRF(43%) LRM(6%) and HRG(52%) groups in the handgrip In the walking speed: The NRG (1 79m/s) is significantly lower than LRF (1 31m/s) 37% and HR (1 35m/s) 33% (p< 05) The speed of LRM (1 67m/s) is significantly slower than HR(1 35m/s)24% (p< 001) In part 2: In the dynamic balance part: NR (6 23 seconds) LR (5 95 seconds) and MR (5 93 seconds) are significantly better than HR (9 07 seconds) (p< 05) In the aerobic endurance: NR (99 32 times) LR ( 100 13 times) and MR (100 32 times) are significantly better than HR (59 00 times) (p< 05) In the closed eye standing on the cushion: MR (2 67 stability index) and HR (2 39 stability index) are better than NR (3 31 stability index) (p< 05) In the reaction time: NR (529 32 seconds) LR (435 20 seconds) and MR (465 14 seconds) are significantly faster than HR (743 50 seconds) Handgrip had 16 3% affected by two minutes step 30-second chair stand and 12-second chair stand Gait speed had 32 2% affected by 8-foot up-and-go and handgrip SMI had 37 7% affected by back scratch 30-second arm curl and handgrip Conclusions: The risk of sarcopenia will increase resulting from the muscle strength of the upper limbs decreased in female older adults However elderly people with low muscle mass will not affect their functional adaptability unless their grip strength is still low It is recommended to consider the mechanism and extent of the interaction between muscle mass and body function for further
