RACQUET SCIENCE — using physics to help select a racquet

Rankings: Shoulder safety

The best (Prince Graphite Classic OS) are the safest for the shoulder; the worst (Wilson Triads) are not recommended. The macro criterion of Shoulder Safety comprises the evaluation criteria of Shoulder Crunch, Shoulder Pull, Torque, and Impact Force. Impact Force had exactly the same rankings as Impulse Reaction. Each of these evaluation criteria (Torque, etc.) produced composite rankings when the results under the 5 Benchmark Conditions were compiled, weighted, summed, and sorted. These composite rankings then were weighted equally, summed, and sorted to produce rankings under the macro criterion of Shoulder Safety.
