Training shoulders with elastic band just as effective as using weights
It doesn't matter whether you do shoulder exercises like lateral raises or external shoulder rotations with dumbbells or with elastic bands. Sports scientists at the National Research Centre for the Working Environment in Denmark discovered this.
Study
Exercises such as lateral raises and lying external shoulder rotations can help people with these problems.
The researchers placed electrodes on the important muscles in the women's neck and shoulders, such as the infraspinatus, the medial deltoid and the splenius capitis. The electrodes enabled the researchers to measure the intensity with which the women used their muscles.
On different occasions the women had to do 3 reps with an increasing load – either with heavier weights or with stronger elastic bands. They were instructed to keep their movements controlled.
Results
Conclusion
"It should be noted that all exercises were performed in a controlled manner and that differences between elastic tubing and dumbbells may exist during more explosive movements. Whereas the inertia of the dumbbell results in increased total moment of force during accelerative movements, the inertia of the elastic tubing is negligible."
"Thus, the results of the present study apply only for exercises performed according to general recommendations of basic strength training and rehabilitation (ie, in a controlled manner without sudden jerks or acceleration)."
