Abstract: The purpose of this study was to examine the within-day and
between-days reproducibility of isokinetic parameters of knee, shoulder and
trunk movements. Ten healthy males (age 30 ± 8 years, height 1.79
± 0.05 m, body mass 79.4 ± 8.3 kg) performed isokinetic
concentric contractions (knee: 60 and 180°/s; shoulder: 60 and 180°/s:
and; trunk: 15 and 60°/s) at 0 (baseline), 2, 24, 48 and 72 hours.
Reproducibility of the baseline peak moment, mean peak moment and maximum work
was assessed using Bland and Altman limits of agreement and pre-planned paired
t-tests (P< 0.05). Peak moment of knee, trunk and shoulder extensors at low
velocities had highest reproducibility within and between days over a time
period of 3 days. Peak moment at high and low velocities of knee extensors was
consistently the most reliable parameter over a 3 day period. It is concluded
that isokinetic parameters can be reproducibly measured in a combined session
of knee, shoulder and trunk movements in healthy male subjects over a 3-day
time period.
