|  |  | r | R2 (SEE) | p | RE | 
| Shoulder abduction | AM | 0.92 | 0.84 (0.86) | 0.000 | 2.03 x (WN) – 0.303 | 
| OB | 0.85 | 0.73 (1.07) | 0.000 | 2.019 x (WN) – 0.823 | 
| Elbow flexion | AM | 0.94 | 0.88 (0.79) | 0.000 | 2.185 x (WN) – 0.861 | 
| OB | 0.85 | 0.73 (1.03) | 0.000 | 1.98 x (WN) – 0.673 | 
| Hip abduction | AM | 0.96 | 0.93 (0.84) | 0.000 | 2.078 x (WN) – 0.799 | 
| OB | 0.90 | 0.82 (0.96) | 0.000 | 2.001 x WN) – 0.811 | 
| Hip extension | AM | 0.95 | 0.89 (0.87) | 0.000 | 2.171 x (WN) – 0.703 | 
| OB | 0.88 | 0.77 (1.13) | 0.000 | 2.306 x (WN) – 1.576 | 
| Overall for all exercises | AM | 0.95 | 0.90 (0.85) | 0.000 | 2.123 x (WN) – 0.694 | 
| OB | 0.88 | 0.77 (1.05) | 0.000 | 2.078 x (WN) – 0.975 | 
SEE: Standard error of the estimation. RE: regression equation (i.e., value in RPE EB can be predicted for RISE Scale value); WN: word number from RISE Scale (1 = easy, 2 = low, 3 = moderate, 4 = hard, 5 = maximal). AM: active muscles. OB: overall body.
