By twelve participants was assigned to the four condition(F-NR, F-R, L-NR, L-R) through three tasks of each opposite condition, and was assigned according to position change of primary task, whether presenting of reminder trial or not, and difference of retention interval. The results of this study are as follows: All conditions of acquisition performance was appear that improvement of performance across trial blocks. When reminder trial was given, log-AE were slower than the other condition during practice at the position of first and at acquisition for 17th trial. When the primary task was practice at the position of first, log-AE was faster in retention when reminder trial was given compared to when a reminder trial was not given. When the primary task was practiced last, performance was no different in retention when a reminder trial was given compared to when a reminder trial was not given. Performance in retention was no different when the primary task was practiced first and a reminder trial was given compared to when the primary task was practiced at last position.

The purpose of this study was to examine the correlation between back strength and cardiovascular function response to maximal exercise of chronic low back pain patients(n=13). By using BRUCE PROTOCOL, subjects underwent treadmill exercise test. Their cardiovascular function responses(HR, VCO₂, VE, VO₂, VO₂/㎏) were measured during rest and after maximal exercise. Back strength was measured at angles 0° (degrees) up to a 72° range of motion(72° , 60°, 48°, 36°, 24°, 12°, 0°) by Medx Lumbar Extension Machine. The responses were analyzed using pearson's correlation for SPSS 7.0 program. Results show that : 1. Between rest, VO₂ and back strength at 24° (r=.64), 36° (r=.66), 48° (r=.66), 60° (r=.61) were significantly correlated(p<.05). 2. After maximal exercise, there was no significant correlation between back strength and cardiovascular function.
