Flyes and reverse flyes: an elastic band instead of dumbbells
Study
The researchers placed electrodes on the skin of the test subjects with which they could see how hard the muscles underneath had to work.
Results
In general, both versions of the flyes and the reverse flyes have approximately the same effect on the pectoralis major and the posterior deltoid, respectively. But if you look more precisely, you will see that the dumbbell exercises provide a bit stronger stimuli than the elastic band exercises.
On the other hand, the stimulation of the supporting muscle groups during flyes and reverse flyes, such as the anterior deltoid and the deltoid medius at the reverse flyes, is greater when the subjects used an elastic band.
Conclusion
"However, elastic resistance bands increased the muscle activation level substantially in the deltoideus anterior in flyes, and deltoideus medius and trapezius descendens in reverse flyes, possibly due to elastic bands being a more unstable resistance modality."
"Overall, the results show that elastic resistance bands can be considered a feasible alternative to dumbbells in flyes and reverse flyes."
