To evaluate the differences of physical fitness of male spinal cord injured (SCI) patients, a graded cycling exercise test using a hand ergometer was performed, monitoring gas exchange, ventilation and heart rate. Thirty-eight cervical SCI patientss (C 6 〜 C 8, C group) (Mean age=26.5 years, SD = 7.5 years), 28 thoratic SCI patients (T 1 〜 T 8, T group) (Mean age = 25.4 years, SD = 10.4 years) and 9 lumbar SCI patients (L 1 〜 L 3, L group) (Mean age = 28.1 years, SD = 7.6 years) participated in this study. The following results were obtained : 1) The each value of percent maximal oxygen uptake (%V^^・O_2) compared with the expected value was 40.9±15.8, 69.9±22.1 and 85.8±22.6%, respectively. There was no statistically significant difference in the %V^^・O_2 between T group and L group (P = 0.0695). That of peak load (Load max) was 35.2±24.1, 85.4±31.1 and 89.0±20.0 watts, respectively. The each value of these two indices was significantly low in the C group. 2) The each value of oxygen uptake per body weight (V^^・O_2/W) was 11.8 ±2.7, 20.4 ±3.8 and 23.8±2.7%, respectively. That of percent maximal heart rate (%HR) compared with the expected value was 62.4±13.7, 88.2±15.7 and 87.2±14.2%, respectively. That of peak minute ventilation (V^^・_E) was 33.0±10.8, 56.1±19.9 and 66.4 ±21.5 1/min, respectively. Compared with the values of T group and L group, the values of C group were significantly lower in these three indices. There was no significant difference in the V^^・_E between T group and L group (P =0.0990). 3) Percent vital capacity (%VC) was 60.4±18.6, 78.4±19.3 and 97. 7±7.9%, respectively. The values of C group and T groups were significantly lower than the value of L group. There was a significant difference in the %VC between C group and T groups. Forced expiratory volume at one second (FEV1.0%) was 94.2 ±8.8, 89.8 ±8.2 and 87.9±7.2%, respectively. These results suggest that the %V^^・O_2, V^^・_E and %VC may be useful as the indices of physical fitness of SCI patients. These factors should be paid much attention to improve the low endurance in SCI patients.
