Abstract |
The purpose of this study is to provide the scientific basic data whether it is feasible to set the appropriate exercise-strength through RPE without using the restricted checking method such as the expensive equipment and place to set the exercise strength for the disabled using the wheel chair. Total 20 experimentees made the letter of agreement to participate into this experiment. The physical characteristics of participants were shown as; Age: 30.9±5.0, Stature: 172.4±3.3, Weight: 63.9±4.8, Blood pressure: contraction period: 131.7±12.8, relaxation period 78±13.5, Damaged part: T3-7 (N=7), T10-12 (N=10), L3 (N=3), Period of disability: 6.4±3.7, Cause of disability: Traffic accident (N=12), Hurt from a fall (N=6), Disease (N=2). The examination on heart rate and RPE was performed through the maximum exercise load examination using the wheelchair after pilot test. The stepwise analysis on RPE and heart rate showed the difference of ±10 beat in heart rate from step 1 to step 12 and RPE showed more than 20 beats than heart rate from 13 step to 16 step. The correlation between RPE and heart beat showed the significant correlate with step 1 to step 4. Medium level significant correlation was shown from step 5 to step 11 (p<.05). The case of the latter part of exercise did not show the significant correlation from step 12 to step 16. It could be considered that the application of RPE is feasible from low strength to middle strength using RPE to spinal cord injury as a subjective scale for exercise-strength from the summary of the above results. However, the correlation was very low when it goes to high strength and the difficulties in verifying the feasibility due to the reasons that the experiment was forced to be performed by few experimentees, and among them those who have not taken exercises would have gone through mental discomforts which might have affected the experiment results. Therefore, for the upcoming experiments, precise exercise test method for the SCI is needed at various environments to meet the needs to reverify the correlation between RPE and Heart rate. |
