These are the results of measuring the lower extremity muscle strength and the aerobic capacity of disabled people with cerebral palsy (Table 1). The lower extremity muscle strength measured peak torque/BW to be 105.49 \(\pm\) 33.35 at 45\({}^{\circ}\)/s of HIP Joint and Agon/Antag ratio was 226.15 \(\pm\) 119.20. Additionally, peak torque/BW was 120.23 \(\pm\) 47.13 at 300\({}^{\circ}\)/s and Agon/Antag ratio was 199.43 \(\pm\) 91.60. For the KNEE Joint at 60\({}^{\circ}\)/s, peak torque/BW was 167.43 \(\pm\) 39.72 and Agon/Antag ratio was 45.87 \(\pm\) 12.09. In addition, the KNEE Joint at 300\({}^{\circ}\)/s, peak torque/BW was 106.90 \(\pm\) 18.88 and Agon/Antag ratio was 77.09 \(\pm\) 9.86. Finally, the aerobic capacity was 37.63 \(\pm\) 8.12 for VO\({}_{\text{2 peak}}\) (mL/kg/min), 78.71 \(\pm\) 23.00 for VE\({}_{\text{peak}}\) (l/min), and 186.90 \(\pm\) 12.05 for HR\({}_{\text{peak}}\) (beats/min). This is the result of correlation analysis to find out the relationship between the lower extremity muscle strength and the aerobic capacity of disabled people with cerebral palsy (Table 2). As such, VO\({}_{\text{2 peak}}\), among aerobic capacities, displayed a significant positive correlation in 45\({}^{\circ}\) and 300\({}^{\circ}\)/s peak torque/BW of HIP joint, and with 60\({}^{\circ}\) and 300\({}^{\circ}\)/s peak torque/BW of KNEE Joint. In addition, it was the same with 60\({}^{\circ}\)/s Agon/Antag ratio of KNEE Joint (\(p<\) 0.05). Likewise, VE\({}_{\text{peak}}\) showed a significant positive correlation with 45\({}^{\circ}\) and 300\({}^{\circ}\)/s peak torque/BW of HIP joint along with the same correlation with 60\({}^{\circ}\) and 300\({}^{\circ}\)/s peak torque/BW and 60\({}^{\circ}\)/s Agon/Antag ratio of KNEE Joint (\(p<\) 0.05). However, HR\({}_{\text{peak}}\) showed a significant positive correlation only in 45\({}^{\circ}\)/s peak torque/BW of HIP joint (\(p<\) 0.05). This is the result of step-wise analysis to find out which muscle strength significantly affects \(\text{VO}_{\text{2 peak}}\) among aerobic abilities in the lower extremity muscles of those disabled with cerebral palsy (Table 3). Among the muscle functions of lower extremity muscle strength, 300\({}^{\circ}\)/s peak torque/BW of KNEE was found to have the greatest effect on \(\text{VO}_{\text{2 peak}}\) (\(p<0.001\)). As a result, 300\({}^{\circ}\)/s peak torque/BW of KNEE was found to be the predictable factor that could explain the \(\text{VO}_{\text{2 peak}}\) in disabled people with cerebral palsy at 66% (R\({}^{2}\) = 0.661). This is the result of step-wise analysis to find out which muscle strength significantly affects \(\text{HR}_{\text{peak}}\) among aerobic abilities in the lower extremity muscles of those disabled with cerebral palsy (Table 4). Among the muscle functions of lower extremity muscle strength, 45\({}^{\circ}\)/s peak torque/BW of HIP, in particular, was found to have the greatest effect on \(\text{HR}_{\text{peak}}\) (\(p<0.001\)). As a result, this factor was found to be the predictable factor that could explain the \(\text{HR}_{\text{peak}}\) in the disabled people with cerebral palsy at 39% (R\({}^{2}\) = 0.392).
