The Claim
High-load overhead press training to failure increases scapular dyskinesis, as measured by scapular balance angle and lateral scapular slide distance, in recreational collegiate weightlifters aged 18–24, compared to non-failure training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In recreational collegiate weightlifters aged 18–24, performing overhead presses to muscular failure results in greater scapular dyskinesis, measured by scapular balance angle and lateral scapular slide distance, than performing the same exercise without reaching failure.
See the scientific wording
High-load overhead press training to failure increases scapular dyskinesis, measured as scapular balance angle and lateral scapular slide distance, in recreational collegiate weightlifters aged 18–24, while non-failure training does not, suggesting that failure training may disrupt shoulder girdle stability.
Lifting heavy weights until exhaustion exhausts the muscles around the shoulder and core, which blunts their ability to sense position and coordinate movement. This causes the shoulder blade to move abnormally because the brain can no longer control it precisely, leading to instability and misalignment.
What the research says
1 studyLifting heavy weights until you can't do another rep made people's shoulder blades move in an unstable, abnormal way, but stopping before exhaustion kept them stable. So going all the way to failure might hurt your shoulder posture.
