Correlation between hypermobility score and injury rate in artistic gymnastics

Youth Sport Specialization and Risk of Injury: A General Review

OBJECTIVE

The purpose of this literature review was to analyze, understand, and disclose prior empirical findings about the injury risks associated with youth sport specialization.

DATA SOURCES

Articles were included in this review if they examined the association between youth sport specialization status and injury. Nine articles from 5 journals met these criteria. All articles summarized the findings of cross-sectional (N = 5) or cohort studies (N = 4).

MAIN RESULTS

Each article included in this review indicated that specialized youth athletes are more susceptible to injury. Only 5 studies assessed the injury risks linked to specialization independent of sport training volume. These studies produced contradictory results.

CONCLUSIONS

Although specialized youth athletes are more prone to injury, future research is needed to determine the independent and inherent injury risk associated with specialization. Nevertheless, youth athletes should refrain from specialization until at least adolescence.

Screening Tools as a Predictor of Injury in Gymnastics: Systematic Literature Review

Background

Gymnastics requires a high level of physical ability and technical skill which utilises short sets of athleticism and artistry to perform complex and intense movements which can overload musculoskeletal tissues and result in acute injuries which can develop into chronic injuries. The aim of this systematic literature review was to investigate which screening tools predict injury in gymnasts and encompasses all genres, levels and ages.

Methods

An electronic search of seven databases from their inception until March 2021 was conducted. The databases were the Allied and Complementary Medicine Database, CINAHL, eBook Collection (EBSCOhost), MEDLINE, Cochrane Database of Systematic Reviews, SPORTDiscus and PEDro (the Physiotherapy Evidence Base). A combination of the following search terms was used: (1) Gymnastics AND injury AND Screening, (2) Screening AND Gymnastics and (3) Musculoskeletal AND Screening AND Gymnastics. These terms were searched in all text, abstract, title and subject terms. Studies were assessed using a 20-point scoring tool.

Results

The mean methodological quality score was 13.1 points (range 10–17 points). Range of motion, anthropometric and postural measurements, hypermobility, clinical diagnostic tests, movement screening tools, muscle strength, power and endurance were reported in the included studies. Some evidence existed for screening measurement of height and mass as taller and heavier gymnasts might be more susceptible to injury; however, the different methodologies utilised and lack of acknowledgment of confounding variables limit the clinical relevance of these findings.

Conclusions

Height and mass should be recorded during the screening process. A lack of heterogeneity in study methodology prevented a meta-analysis. Studies were limited by a lack of prospective injury design, poor injury definition, self-reporting of injury and only 2 studies reported reliability of screening tools. Further research is required to determine the role of injury screening in gymnastics.

Registration: The review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) with the registration number CRD42020218339.
