PURPOSE: This study investigates the relationship between leg power and sit-to-stand (STS) transitions in older adults. METHODS: After wearing an activity monitor for a week, independent living and assisted living older adults were grouped into terciles based on STS transitions. Leg power was measured via a linear transducer that can assess power associated with repeated standing movements. STS transitions were compared to leg power using a One-Way ANCOVA, controlling for age. Groups were delineated as follows: Low STS Group (n=12, M_age=79.83, M_transitions=34.35), Moderate STS Group (n=11, M_age=76.45, M_transitions=45.12), and High STS Group (n=10, M_age=77.70, M_transitions=65.49). RESULTS: While the Moderate STS Group exhibited a higher average leg power (M=5.63, SD=2.55) than the Low STS Group (M=4.20, SD=1.50) and High STS Group (M=4.05, SD=1.29), this difference was not significant, (F(2,29) = 2.64, p = 0.09). CONCLUSION: While no significant difference was found, the Moderate STS Group displayed a trend of higher leg power. Factors like assistive device use, living arrangements, and a potential ceiling effect in well-functioning older adults may influence these results. Further research is needed to comprehensively understand the relationship between leg power and STS transitions in aging populations.
