Background: Both the Y-balance test (YBT) and Sit-To-Raise test (SRT) appear to share similar requirements in terms of physical attributes needed for test performance. Nonetheless, to date, there are no studies comparing performance between these two movement tests. Objectives: To determine the strength of association between SRT and YBT scores, as well as report participant performance characteristics for each test. Setting: Field-based data collection. Participants: A convenience sample of 100 healthy adults (n=69 males, mean ± SD age was 29.8 ± 11.1 years, body weight 86.3 ± 12.0kg, and height 177.4 ± 7.4cm; n=31 females, age 29.8 ± 8.9 years, body weight 64.1 ± 9.3 kg, and height 166.5 ± 6.5cm) were recruited from a recreation centre and other campus facilities. Main outcome measures: SRT and normalised YBT scores were administered using standardised test protocols and scoring criteria. Results: Right and left anterior YBT reach direction and total SRT scores were moderately correlated for the right (r = 0.469) and left (r = 0.352) anterior reach directions. Additionally, all other individual, as well as composite reach directions of the YBT displayed a small correlation with the SRT (r = 0.202 to 0.352). The sitting component of the SRT had a small negative correlation (r = - 0.160, p = 0.111) with height, and age (r = - 0.259, p = 0.009), but no clear correlation was found between the participant’s height (r = 0.023, p = 0.821), height to leg-length ratio (r = -0.079, p = 0.433) and SRT sitting component performance (r = -0.079, p = 0.433). The SRT raising component had a small negative correlation with body weight (r = - 0.267, p = 0.007), and age (r = - 0.174, p = 0.083) but no clear correlation with participant’s height (r = -0.135, p = 0.179), or height to leg length ratio (r = -0.096, p = 0.345). Conclusions: The small to moderate correlation between total SRT scores and all YBT reach directions indicates each test addresses a similar underlying construct.
