A study watched people for 8 weeks and saw no injuries, but it wasn't actually set up to check if injuries would happen—so we can't say for sure whether the movement being studied causes injuries or...

Similar Assertions

Using external momentum during resistance training does not appear to raise the risk of injury in beginners over 8 weeks, but the study was too short and too small to determine risks over longer periods or for soft tissue injuries.
