EMG STUDIES
PECTORALIS MAJOR UPPER & MIDDLE + UPPER TRAPEZIUS
– DB Press Flat vs. DB Press 45º Incline vs. DB 85º Overhead
Shoulder Muscle Activation of Novice and Resistance Trained Women during Variations of DB Press Exercises – 2013 – Luczak, Bosak, Riemann
Procedure
– collegiate-aged female resistance trained individuals and novice female resistance trained exercisers
– using 4.5 kg dumbbells
Electrode Placement
1. clavicular portion of the pectoralis major, electrodes were placed four finger widths below the medial clavicle just medial to anterior axillary border
2. sternal portion, electrodes were placed four finger widths below the sternoclavicular joint; Note: this would the sternal or middle region
3. anterior deltoid, electrodes were placed at one finger width distal and anterior to the acromion.
4. upper trapezius, electrodes were placed at 50% of the distance between the acromion process and the spine of the seventh cervical vertebra.
Results – Concentric
– No significant differences were found between experienced and novice resistance trained individuals; Note: a very light weight was used
Pectoralis – Clavicular or Upper Region: 45°db incline 175% · db flat bench 130% · 85°db overhead 90%
Pectoralis – Sternal or Middle Region: db flat bench 130% · 45°db incline 115% · 85°db overhead 90%
Anterior Deltoid: 85°db overhead 355% · 45°db incline 265% · db flat bench 130%
+ Upper Trapezius: 85°db overhead 1165% · 45°db incline 375% · db flat bench 100%
