摘要: Abstract Repetitive work is common in the modern workplace and effects are often studied using fatigue protocols; however, there evidence that manner which develops impacts kinematic muscular response to reduced physical capacity. The purpose of this study was simultaneously evaluate adaptations during fatiguing, repetitive until exhaustion. We measured muscle activity 13 muscles shoulder trunk, captured full body kinematics while participants completed simulated, tasks. Every 12 min, reference data were collected quantify fatigue. This sequence continued they reached termination criteria. Participants displayed significant signs fatigue, loss strength increased perceived (p
