This study compared sit to stand (STS) performance between older adults in a nine-week training program focusing on core stability exercises to enhance balance and postural control (EB) versus standard balance (SB) exercises. Repetitions in 30 s (STSreps) and kinematic performance (vertical and horizontal momentum, and margin of stability) were measured pre and postintervention in 23 older adults with at least one fall risk factor. Although both groups combined improved STSreps (p = 0.001) and vertical momentum (p = 0.008), a significant between-group difference was observed for completers only (MANCOVA of posttest group differences, with pretest scores as covariates; p = 0.04). EB demonstrated a greater but nonsignificant improvement in vertical momentum (p = 0.095). In conclusion, core stability training added to SB did not result in STS reps improvement. Compliance may modify these results and future larger sample studies should evaluate the impact of core stability training on STS biomechanics.
