changing demands on the shoulder complex that are not fully understood. The purpose of …

This study compared the muscular activation of the pectoralis major, anterior deltoid and
triceps brachii during a free-weight barbell bench press performed at 0°, 30°, 45° and–15° …

Delayed onset muscle soreness (DOMS) indicates the presence of muscle damage and
impairs force production and control. Monitorization of DOMS is useful to improving recovery …

Objective: The authors developed a function to quantify fatigue in multiple shoulder muscles
by generating a single score using relative changes in EMG amplitude and frequency over …

activation of upper leg muscles similar to resistance exercise (RE) at an intensity required to …

The rotator cuff muscles are prominent stabilizers of the shoulder and are vulnerable to
muscle fatigue. Rotator cuff fatigue may result in subacromial impingement (SAI) through the …
