The 30-s Chair-Stand (CS30s) and the Timed Up and Go (TUG) are functional tests designed to provide information about lower limbs’ muscle strength and functional agility in the elderly. Although both tests are intended to assess different aspects of functional fitness, the level of shared variance between these tests has not been determined yet. This study aimed to verify the correlation between the TUG and the CS30s. Forty-seven healthy women volunteered to participate in this study. The participants participated in a 60-minute water exercise program that occurred twice weekly for at least 6 months. The CS30s and the TUG were administered to each subject, respectively, always in this order. The results from Pearson’s correlation were calculated using the maximal number of repetitions performed in the CS30s test and the time spent performing the TUG test. There was a significant but low correlation (r = -.563; p < .05). A shared variance of 31.7% was observed, so it is possible to speculate that these tests are related to different neuromuscular demands. The scores obtained from the CS30s were 8.1% higher than the ones found in the reference values from the literature for this target group, while the scores from the TUG were similar.
