Reliability of peak isometric force at ISq120 and ISq90 (n = 59).
| Peak Force (N) | ||||
|---|---|---|---|---|
| Day 1 [Mean (SD)] | Day 2 [Mean (SD)] | Difference (Day 2–Day 1) Mean [LLOA, ULOA] |
||
| ISq120 | 1579 (536) | 1536 (567) | −44 [−100, 12] | |
| ISq90 | 1035 (298) a | 958 (275) a | −73 [−114, −32] | |
| Test-Retest Reliability | ||||
| CV [Mean (SD)] | ICC [95% CI] | TE (N) | TE (%) | |
| ISq120 | 7.5 (6.7) | 0.960 [0.933, 0.977] | 140.2 | 9.5 |
| ISq90 | 9.2 (8.8) | 0.920 [0.865, 0.953] | 82.6 | 8.8 |
LLOA = Lower limits of agreement, ULOA = Upper limits of agreement, CV = coefficient of variation, ICC = intraclass correlation coefficient, TE = Typical error, 95% CI = 95% confidence interval, a = significantly different peak isometric force from the ISq120 position (p < 0.001).
