When people do a shoulder exercise standing with a resistance band, tennis players and other athletes use their shoulder blade muscles about the same—so this exercise doesn't reveal the differences seen in other exercises.

Scientific Claim

No significant differences in trapezius activation or symmetry were observed during standing bilateral scapular retraction with resistance bands at either 45° or 90° between tennis players and non-tennis athletes, suggesting this exercise modality may be less sensitive to detecting sport-specific neuromuscular adaptations.

Original Statement

No significant differences were observed in the mean RMS at 90° across any of the muscles analyzed (p > 0.05). No significant differences were found in the mean RMS for any of the muscles analyzed at 45° (Figure 8).

The study found that tennis players use their shoulder muscles differently than other athletes during the same exercise, meaning the exercise *can* detect differences caused by playing tennis—so the claim that it can’t is wrong.
