Understanding individual differences in lifting mechanics: Do some people adopt motor control strategies that minimize biomechanical exposure
DP Armstrong, SL Fischer - Human Movement Science, 2020 - Elsevier
The movement strategy an individual uses to complete a lift can influence the resultant
biomechanical exposure on their low back. We hypothesize that some lifters may choose a …
