Subjects were 7 men (age 30 ± 6 yr.) with a spinal cord injury (SCI) and 6 able-bodied (AB) men (age 34 ± 8 yr.). All subjects exercised by the arm-crank ergometer which was designed to maintain the constant work rate. The work rate was increased by 10watts/min.. During the incremental exercise V02, VC02, VE, and heart rate were measured continuously. Grip strength (kg) and AMA (Bone-free upper arm muscle area, cm^2) were evaluated by the mean value or both upper extremities. The peak V02 values or SCI and AB were :33.9 ± 5.0 (mean ± SD) and 27.6 ± 5.4 ml/kg/min. respectively, which were significantly different. Some subjects were not able to exercise until attaining the 90% of the maximum heart rate estimated by their age ( = 220-age). They showed a tendency to have inferior grip strength. The significant correlation was observed between the peak VO2 and the grip strength of all subjects (r = 0.78). It was suggested that upper extremity exercise by arm-crank ergometer was limited by peripheral factors which originated from muscular fatigue and discomfort in advance of being limited by central circulatory factors. Because the imbalance of peripheral factors and central circulatory factors could restrict performing the maximum physical capacity, we recommend that wheelchair athletes should increase their muscular strength by strength training.}, pages = {63--69}, title = {脊髄損傷者の腕エルゴメータ漸増負荷運動時における運動の限界因子の検討}, volume = {17}, year = {1994} }
