Reliability and validity measures for lower limb flexibility tests.
| Lower limb flexibility | Measured variable | Reliability | Construct validity (correlation with self-reported climbing ability) |
|---|---|---|---|
| Sit and reach (3, 47, 95, 97, 114, 169) | Low back + hamstring Active static FLEX | Inter-session: ICC = .97 (169) | r = 0.17–0.42 (95) |
| Lateral foot reach (169) | Hip active static FLEX | Inter-session: ICC = .93 (169) | r = .24 –.30 (169) |
| Grant foot raise (3, 95, 97, 110, 169, 170) | Hip active static FLEX | Inter-session: ICC = .90 –.93 (169) | r = .20 –.34 (110, 169); r = .26 –.49 (95) |
| Climbing specific foot raise (14, 15, 32, 169) | Hip active static FLEX | Inter-session: ICC = .89 (169); r = .95 –.99 (15) | r = .53 –.95 (14, 15, 169) |
| Hip abduction test (6, 131) | Hip active static FLEX | – | r = .14 (6)+ |
| Draga test (170) | Hip active static FLEX | – | – |
| Hip slide test (134) | Hip active static FLEX | – | – |
| Foot loading flexibility test (169) | Hip active static FLEX/Climbing ability | Inter-session: ICC = .96 (169) | r = .56 –.65 (169) |
| Asymmetry in reach test (113) | Hip active static FLEX/Climbing ability | Intra-session: ICC = .89—>.99, CV% = 1.31–35.20, SEM%=.09 –.61 (113), inter-session: ICC = .87 -.96, CV% = 4.96–41.98, SEM% = .07–1.57 (113) | – |
| Froggies (5, 30) | Hip passive static FLEX | – | – |
| Straddle test (3, 95, 97, 134, 170) | Hip + lower limb passive Static FLEX | – | r = -.48—-.41 (170); r = .16 –.57 (95) |
| Hip rotation and flexion (131) | Hip active FLEX | – | – |
| Leg flexion (131) | Lower limb active FLEX | – | – |
