30 Seconds SummaryIs spinal flexion actually dangerous when squatting or deadlifting?
- Spinal flexion under load, such as during squats and deadlifts, increases shearing stresses on the spine, potentially increasing injury risk.
- Traditional advice emphasizes a neutral spine to minimize these stresses, supported by biomechanical studies and limited data from living humans.
- However, Total absence of evidence in living humans lifting heavy weights means that the debate over safe lifting technique continues.
- Some studies suggest that instructing manual laborers to maintain a neutral spine doesn’t significantly reduce injury rates, while others see benefits.
- Pain science research suggests pain is a complex experience not directly correlating with tissue damage, impacting our understanding of back pain.
- Anecdotal observations from coaches generally support the theory that less spinal flexion during heavy lifting leads to fewer injuries.
- Despite some arguments against strict spinal neutrality, maintaining a less flexed spine is generally seen as safer and more effective for heavy lifting.
