Summary of an article on the differences in injuries between CrossFit and traditional weightlifting (resistance training) adult recreational athletes.
411 adult recreational athletes.
Cohort study, 15 questions, asking about the previous 2 years.
- Injury: “participants (…) self-determine whether an event should be considered an injury”.
- Injury location and medical treatment.
- Supplement use (multivitamins, protein powder, protein bars, branched chain amino acids, creatine, preworkout, DHEA, anabolic steroids, caffeine, fat burners).
- 61% of crossfiters and 47% of traditional weightlifters sustained an injury in the previous 2 years. Crossfiters were 1.3 times more likely to be injured.
- The likelihood of injury in CrossFit was 2.26 times higher (age and sex-adjusted) than in traditional weightlifting.
- 65% of crossfiters and 35% of traditional weightlifters sought medical help. crossfiters were 1.86 times more likely to seek medical help.
- For every 10 years increase in age, the risk of injury decreased by 13% in both sports (sport and sex-adjusted).
- Males were 1.8 times more injured than females (sport and age-adjusted).
- Supplements did not cause an increase in injuries (both groups).
- Most common injuries in both groups were:
- shoulder (44%)
- low back (38%)
- hip (9%)
- Movement while CrossFit athletes were injured most:
- clean and jerk (19%)
- deadlift (19%)

- Movement while traditional weightlifting athletes were injured most:
- bench press (24%)
