The sample was made upof 159 subjects with ID (85 adolescents and 74 adults) of both sexes, with average age of 18.36 (5.26)years, belonging to four special educational centers from Santiago, Chile. Absolute (AHGS) and relative(RHGS) handgrip strength and countermovement jump (CMJ) were considered as muscle strengthevaluation tests. The timed up and go (TUG) and agility test 4 × 10 m were considered as functionaltests. Spearman and intraclass correlations, as well as Bland-Altman plots were used to establish therespective correlations. The average values obtained in the 5R-STS test (s) in adolescents were 6.55 and7.24, while in adults they were 6.82 and 7.17 for men and women, respectively. Significant correlations(p = < 0.05) are established between the 5R-STS test with AHGS (r= -0.48) and RHGS (r= -0.54), CMJ(-0.53), 4 × 10 m test (-0.50) and TUG (-0.49), as well as in the analysis of agreement between 5R-STSand the TUG (ICC = 0.74) and agility 4 × 10 m (ICC = 0.61) tests, both in adolescents and adults of bothsexes. The 5R-STS test is a valid, simple and safe tool to evaluate general and lower extremity musclestrength. Its use is suggested as a simple measure for monitoring functional capacity by professionalsin educational and health contexts for the adolescent and adult population with ID.
