Injury profiles in sub-elite Women's Cricket: Exploring incidence, prevalence, nature, onset and body region.

INTRODUCTION: The rise in participation in sports, like women's cricket, is linked with increased injury risk. Providing high-level longitudinal data is the first step in implementing evidence-based injury prevention strategies. DESIGN: Prospective cohort study. OBJECTIVE: This cohort study aims to describe the injury profiles in sub-elite women's cricket in South Africa during the 2022/23 season. METHODS: Injuries were prospectively recorded using injury surveillance questionnaires, injury surveillance database, and logbooks completed by each team's medical staff. Injury rates were investigated for match and training days, body region, player role, nature, and activity at the time of injury. RESULTS: Three teams with a total of 44 players (20.86 ± 1.6 years) were included in the study. Injury incidence was 85.23 per 1000 player match days, 15.91 for match time-loss and 69.32 for non-time-loss, with 2.95% of players unavailable for match selection on any day. Fast bowlers had the highest injury incidence. Fielding caused 46.67% of all injuries. Injury incidence was higher in training than in matches. The wrist/hand had the highest injury incidence and caused the most match time-loss. CONCLUSION: This study provides valuable insights regarding the current injury rates in sub-elite female cricket players.

Physical Profiles of All-Rounders, Batters, and Bowlers in Sub-Elite Women's Cricket.

ABSTRACT: Jacobs, J, Olivier, B, Brandt, C, and Jafta, G. Physical profiles of all-rounders, batters, and bowlers in sub-elite women's cricket. J Strength Cond Res 38(6): 1095-1102, 2024-The unique physical profile of each player's role in sub-elite women's cricket is vital for optimizing performance as these players progress to the elite levels. This quantitative, cross-sectional study investigates the physical profiles of sub-elite women's cricket players as a group and compares these profiles across different player roles. Sub-elite female cricket players in the South African domestic women's cricket league were included in this study. A battery of physical assessments were conducted at the start of the 2022/23 season. The physical assessments included body composition, individual muscle strength testing using dynamometry, 2-km time trial (TT), countermovement jump (CMJ), single-leg jump (SLJ), isometric mid-thigh pull, push-up, and hop test on force plates. A total of 44 female players (20.86 ± 1.6 years) were included in the study. Differences were found in muscle mass (p = 0.004) and peak power (p = 0.040) for all-rounders and bowlers. Player roles presented with different dominant (p = 0.006) and non-dominant (p = 0.066) knee flexion strength. The bowlers' body composition and physical strength profile are compromised compared with batters and all-rounders. There were several physical strength and power differences between pace and spin bowlers in CMJ and SLJ tests for jump height (p = 0.009) and peak power (p = 0.006). Batters performed the best in the 2-km TT. Body composition and musculoskeletal profiles for each player role can be baseline markers in sub-elite women's cricket. Stakeholders can use this information to guide physical preparation for players advancing to elite levels.

Anthropometric and biomechanical factors in elite male and female fast bowlers.

Researchers have extensively studied the biomechanics and anthropometrics of fast bowling in men's cricket, but there is still limited research in women's cricket. This study describes and compares the anthropometric qualities and bowling biomechanics between elite male and female fast bowlers. An inertial measurement system was used to collect three-dimensional biomechanical data for 20 elite fast bowlers (13 males and seven females). Kinematic data was captured at one step before back foot contact, back foot contact, front foot contact, ball release to one step after ball release. Anthropometric measurements included body segment lengths, mass, body fat (BF%) and muscle mass (MM%). The student t-test and Mann-Whitney U test were used for analyses. Hotelling's T2 statistic was calculated to control Type I error during multiple comparisons (p = 0.045). Males and females differed in overall height, limb length, BF% and MM%. Females presented with slower ball release speeds (p = 0.001). Biomechanically, the females were more front-on when approaching the delivery stride and then initiated pelvis and trunk rotation during the delivery stride, not seen in the males. Females and males have a similar magnitude of trunk side-flexion, but females present with a different strategy than males (p = 0.038). Females presented with increased front knee extension at ball release (p = 0.05). The findings from this study emphasise the differences between male and female fast bowlers and suggest that the coaching principles used in male fast bowling may not be relevant to female fast bowlers.

Prevalence and incidence of injuries among female cricket players: a systematic review and meta-analysis.

OBJECTIVE: The objective of the review was to describe the incidence and prevalence of injuries among female cricket players of all ages, participating in all levels of play. INTRODUCTION: Cricket, a bat-and-ball sport, is becoming popular among women of all ages and abilities worldwide. However, cricket participation carries a risk of injury. Injuries negatively affect sport participation, performance, and short- and long-term health and well-being. Injury prevention, therefore, is the key to safe, long-term cricket participation as a physical activity goal. Epidemiological data are needed to underpin evidence-based injury-prevention strategies. INCLUSION CRITERIA: Studies reporting incidence and prevalence of injuries in female cricket players of all ages, participating in all levels of play, were included in this review, including studies that report data by sex or by sport. Studies were excluded if they did not have enough data to calculate prevalence or incidence, did not distinguish female injury data from male injury data, focused on athletes participating in other sports, or focused on case studies. METHODS: A systematic review and meta-analyses were conducted according to the JBI and PRISMA 2020 guidelines. MEDLINE, SPORTDiscus, Physiotherapy Evidence Database (PEDro), EBSCO MasterFILE Premier, EBSCO CINAHL Complete, ProQuest Health and Medical Complete, Scopus, and ScienceDirect were systematically searched from inception to August 2021. Additionally, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched. EBSCO MegaFile Premier, OpenGrey (SIGLE), WorldCat, Grey Matters, Grey Literature, and Google Scholar were searched for gray literature. Full-text articles that met the inclusion criteria were critically appraised using tools from JBI, and were extracted and synthesized in narrative summary and tabular format. Three meta-analyses were conducted: injury incidence rates, injury prevalence proportions, and injury incidence proportions. Heterogeneity was assessed using the I2 statistic and the random-effects model. RESULTS: Of the 7057 studies identified, 4256 were screened after duplicates were removed. A total of 23 studies met the inclusion criteria. Risk of bias was low for 21 studies. The injury incidence rate for elite cricket was 71.9 (SE 21.3, 95% CI 30.2-113.6) injuries per 1000 player hours, time-loss injury incidence rate was 13.3 (SE 4.4, 95% CI 4.6-22.0) injuries per 1000 player hours, and non-time-loss injury incidence rate was 58.5 (SE 16.9, 95% CI 25.6-91.7) injuries per 1000 player hours. The injury prevalence proportion for community to elite cricket was 65.2% (SE 9.3, 95% CI 45.7-82.3) and the injury prevalence proportion for community cricket was 60% (SE 4.5, 95% CI 51.1-68.6). The injury incidence proportion for community cricket was 5.6 (SE 4.4, 95% CI 0.1-18.3) injuries per 10,000 participants. Elite cricket players were more frequently injured than community cricket players. The most prevalent body regions injured were the shoulder and knee, and most were sustained by fast bowlers. Injuries to the hand, wrist, and fingers had the highest incidence and were most sustained by fielders. CONCLUSIONS: The study's findings can help stakeholders (including players, coaches, clinicians, and policymakers) make informed decisions about cricket participation by informing and implementing strategies to promote cricket as a vehicle for positive public health outcomes. This review also identified gaps in the available evidence base, and addressing these through future research would enhance women's cricket as a professional sport.

Prevalence and incidence of injuries among female cricket players: a systematic review protocol.

OBJECTIVE: The objective of this systematic review is to describe the incidence and prevalence of injuries in female cricket players participating in recreational-, school-, club-, and elite-level cricket. INTRODUCTION: Recent investments in women's cricket, stand-alone tournaments, and increased visibility through new broadcasting milestones has increased participation in many countries. With increased participation of women in cricket comes increased risk of injury. Epidemiological data are needed to underpin evidence-based injury-prevention strategies. No systematic review or meta-analysis of injuries is currently available to provide a comprehensive overview of synthesized findings to make the evidence accessible. INCLUSION CRITERIA: Studies on female cricket players of all ages and participating in all levels of cricket will be included. Studies that contain data on only male cricket players will be excluded. Studies where data from female cricket players can be distinguished from male players will be included. Injuries sustained when playing cricket, that are self-reported or diagnosed by a health care professional will be included. Definitions of injury including, but not limited to, medical-attention injuries, general time-loss injuries, or player-reported injuries will be considered. METHODS: MEDLINE, SPORTDiscus, Physiotherapy Evidence Database (PEDro), EBSCO MasterFILE Premier, EBSCO CINAHL Complete, ProQuest Health and Medical Complete, Scopus, and ScienceDirect will be systematically searched from inception to the present. Cochrane Central Register of Controlled Trials and ClincalTrials.gov will be searched as well as gray literature databases. Retrieval of full-text studies, assessment of methodological quality, and data extraction will be performed independently by two reviewers. If possible, meta-analyses will be performed. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42020166052.

Reliability and validity of the Readiness for Hospital Discharge Scale in patients with spinal cord injury.

BACKGROUND: Measuring rehabilitation outcomes in patients with spinal cord injury (PWSCI) requires measurement tools that are valid and reliable and have been psychometrically tested in the population with spinal cord injury (SCI). The Readiness for Hospital Discharge Scale (RHDS) has been found to be reliable and valid in adult surgical patients, post-partum mothers, parents of hospitalised children and geriatrics. However, the psychometric properties have not yet been tested in the population with SCI, furthermore, in a South African context. OBJECTIVES: The purpose of this study was to psychometrically test the internal consistency and construct validity of the RHDS as a measure of discharge readiness in PWSCI prior to discharge from rehabilitation units in the Tshwane metropolitan area, South Africa. METHOD: A cross-sectional study that included 50 PWSCI who were in their last week of rehabilitation was conducted. The RHDS item and scale statistics were calculated by using descriptive statistics and the scale reliability was measured for internal consistency by using Cronbach's alpha coefficients. To determine construct validity, convergent and divergent validities were measured by using the RHDS items' correlation coefficient dimensions. All data were tested at the 0.05 level of significance by using Statistics and Data (STATA) statistical software, version 14. RESULTS: Cronbach's alpha of the RHDS was 0.904, indicating an excellent reliability coefficient. Convergent validity scores showed 81% correlation coefficients, although divergent validity scores showed 62% correlation coefficients. CONCLUSION: The RHDS is a valid and reliable measure of readiness for discharge in a South African sample of PWSCI and can be used in SCI rehabilitation. CLINICAL IMPLICATIONS: Over and above using the RHDS to determine if PWSCI are ready for discharge in the clinical setting, the RHDS may also assist health care practitioners to assess the patient's progress towards readiness and strategies for addressing shortcomings to meet short and long-term goals of the rehabilitation process.
