| We
evaluated the reliability of static and dynamic lumbar muscle endurance
measurements on a BackUP lumbar extension dynamometer. Sixteen healthy
participants (8 male; 8 female) volunteered for this investigation.
Fifty percent of each participant's body weight was calculated to
determine the weight load utilized for the static (holding time) and
dynamic (repetitions) lumbar extension endurance tests. Four separate
tests (2 static, 2 dynamic) were conducted with at least a 24-hour
rest period between tests. Test-retest intraclass correlations were
shown to be high (static lumbar endurance, ICC = 0.92 (p < 0.0005);
dynamic lumbar endurance, ICC = 0.93 (p < 0.0005) for both of the
performed tests. Our results demonstrated that static and dynamic
lumbar endurance can be assessed reliably on a BackUP lumbar extension
dynamometer.
