A Cross-sectional Study – Review
The Orthopaedic Journal of Sports Medicine, 6(5), 2325967118771016
This was a local study that investigated the prevalence, localization, and characterization of injuries among Swedish classic powerlifters, with an emphasis on differences between men and women, and to investigate whether training and lifestyle factors are associated with an injury.
Seventy percent (73/104) of participants were currently injured, and 87% (83/95) had experienced an injury within the past 12 months. The lumbopelvic region, shoulder, and hip were the most common injured area for both sexes. Women experienced a significantly greater frequency of injuries in the neck and thoracic region than men. Injuries seemed to occur during training.
The study concluded that the Injuries are very common in sub elite powerlifters. Men and women report similar injury frequencies but different anatomic locations. These injuries do not prevent powerlifters from training and competing, but they may change the content of training sessions.
Why powerlifters develop injuries was unclear in the study; however, it is likely that the management of training loads and optimization of the lifting technique during the squat, bench press, and dead lift are of importance and affected the ration of injuries.

Athletes may benefit from receiving visual feedback of kinematic outcomes during training periods, particularly when (1) training quality is of importance, (2) training volume is high, or (3) motivation is low.
This study examined the effects of visual kinematic feedback during the back-squat exercise.

In this paper, 71 sprinters and jumpers (S/J), 54 weightlifters (WLs), and 86 controls had their DNA analysed via a blood sample.
The aim of the current study was to examine genetic differences between subtypes of anaerobic athletes in 3 genetic variants: ACTN3 R577X, which is associated with muscle contractions; AGT Met235Thr which is associated with muscle growth; and PPARD T/C.
The results suggest that there may be a specific genetic makeup enabling an athlete to excel in speed-oriented events (sprints), rather than in strength-oriented events (weightlifting).
