Design outcomes
Primary
| Measure | Time frame |
|---|---|
| External rotators strength and flexibility testes with an isokinetic dynamometer ISOMED2000: - mean and peak torque for 30 and 60°/s eccentric and concentric - maximum range of motion, maximum stiffness, tension-angle curvature Muscle adaptions tested with 3T Siemens Prisma MRI scanner, 16-channel shoulder coil, dti-based fiber tracking: - muscle tract length - absoulte muscle tract volume - muscle volume | — |
