Effects of Body Position and Loading Modality on Muscle Activity and Strength in Shoulder Presses – 2013 – Saeterbakken
– dumbbells vs barbell in front of the neck and standing vs seated; EMG testing 80% 1RM
– anterior deltoid 1.22% to 1.00%: standing db > seated db > standing bb >  seated bb
– middle deltoid 64% to 56%: standing db > standing bb > seated bb + seated db
– posterior deltoid 42% to 32%: standing db = standing bb > seated db = seated bb
– the exercise with the greatest stability requirement (standing and dumbbells) demonstrated the highest neuromuscular activity of the deltoid muscles, although this was the exercise with the lowest 1RM strength

Different Shoulder Exercises Affect the Activation of Deltoid Portions in Resistance-Trained Individuals – 2020 – Campos
– 13 men experienced in strength training; maximum isometric voluntary contraction (MVIC); one set of 12 repetitions with the load of 60% 1RM
– compare muscle activity of the anterior deltoid, medial deltoid, and posterior deltoid in the:
(1) bench press (2) dumbbell fly (3) seated back to bench shoulder press: (4) seated back to bench lateral raise – anatomical position
– anterior deltoid: shoulder press 33%; lateral raise 21% = bench press 21%; db flye 18%
– medial deltoid: lateral raise 30%; shoulder press 28%
– posterior deltoid: lateral raise 24%; shoulder press 12%
