Effect of menstrual cycle and contraceptive pill phase on aspects of exercise physiology and athletic performance in female athletes: protocol for the Feminae international multisite innovative project.

The idiom 'more high-quality research is needed' has become the slogan for sport and exercise physiology-based research in female athletes. However, in most instances, it is challenging to address this gap of high-quality research in elite female athletes at a single study site due to challenges in recruiting enough participants with numerous menstrual cycle and contraceptive pill permutations. Accordingly, we have assembled an international multisite team to undertake an innovative project for female athletes, which investigates the effects of changes in endogenous and exogenous oestrogen and progesterone/progestins across the menstrual cycle and in response to second-generation combined monophasic contraceptive pill use, on aspects of exercise physiology and athletic performance. This project will employ the current gold-standard methodologies in this area, resulting in an adequately powered dataset. This protocol paper describes the consortium-based approach we will undertake during this study.

Navigating the 'new normal': what guidelines exist for postpartum return to physical activity and sport? A scoping review.

OBJECTIVE: Women are often advised to return to activity (RTA) as early as 6 weeks postpartum, despite undergoing significant physical, physiological and psychological changes. Our objective was to examine existing evidence and clinical practice guidelines to navigate a safe and successful RTA or return to sport (RTS) postpartum. METHODS: We searched CINAHL, Embase, Medline, PsycINFO and SPORTDiscus and included any secondary studies with recommendations or guidelines for RTA or RTS postpartum. Grey literature and primary sources were excluded. Four reviewers independently screened titles and abstracts, followed by full-text review for eligibility, with conflicts resolved by a third-party reviewer. One reviewer extracted data, which was cross-referenced by another reviewer. RESULTS: 5851 studies were screened, and 33 were included in this scoping review. Most studies stated that RTS postpartum can begin once 'medically safe', around 6 weeks postpartum, but this term was generally left undefined. In addition, most studies recommended engaging in 150 min of moderate-vigorous physical activity per week after 6 weeks postpartum, but the type of exercise recommended was often non-specific. CONCLUSION: A lack of consistent, evidence-based guidelines exist for RTA or RTS postpartum. Multiple evidence gaps require additional research to inform patient and activity specific guidelines for a safe and successful RTA or RTS postpartum.

Filling the evidence void: exploration of coach and healthcare provider experiences working with pregnant and postpartum elite athletes - a qualitative study.

OBJECTIVE: Recent research grounded in the experiences of elite female athletes has shed light on the complex challenges of navigating sport environments that do not support or value pregnant or postpartum athletes. The purpose of this study was to explore the unique experiences of coaches and healthcare providers working with pregnant and postpartum elite athletes, and to identify actionable steps for research, policy and culture change to support them. METHODS: Sixteen participants (five coaches, three physicians and eight physiotherapists), who have worked with pregnant and/or postpartum elite athletes within the last 5 years, participated in this qualitative study. Thirteen participants self-identified as women, and three as men. Data were generated via semistructured one-on-one interviews that were audiorecorded, transcribed verbatim and analysed through a process of content analysis. RESULTS: The findings of this research are represented by five main themes: (a) lack of female athlete reproductive research, (b) need for evidence-informed education and training, (c) need to develop evidence-based progression for sport participation in pregnancy and postpartum, (d) open communication to support athlete-centred care and (e) essential supports and changes required for pregnant/postpartum athletes. CONCLUSION: Findings from this study, which are grounded in the unique perspectives of coaches and healthcare providers, outline specific recommendations to inform policy and practices that support athletes through the perinatal period, such as developing evidence-based return-to-sport protocols.

Effectiveness of Pilates exercise on low back pain: a systematic review with meta-analysis.

PURPOSE: Low back pain is the most frequently reported musculoskeletal disorder and represents one of the highest patient burdens in healthcare. This systematic review and meta-analysis aimed to investigate the effectiveness of Pilates exercise on pain intensity and functional disability caused by low back pain (LBP). MATERIALS AND METHODS: A Systematic review with meta-analysis was conducted. Data sources: MEDLINE-NLM and MEDLINE-EBSCO. We also searched on Scopus Elsevier, Cochrane, DOAJ, SciELO, PEDro, and PLOS ONE databases. Eligibility criteria: randomized controlled trials (RCTs) evaluating LBP in which the primary treatment was based on Pilates exercise compared with no exercise, or non-specific exercise. RESULTS: The search returned 1566 records of which 36 articles were included in the systematic review and 19 in the meta-analysis. Twenty-two studies compared the effects of Pilates exercise vs no exercise and 13 studies examined the effects of Pilates exercise vs non-specific exercise. Analysis showed that Pilates had a positive effect on the perception of LBP vs no exercise. A similar trend occurred with non-specific exercise. CONCLUSIONS: Pilates exercise can decrease LBP compared to no exercise and non-specific exercise. General practitioners should consider Pilates exercise as an effective strategy to manage LBP and counteract the growing health. TRIAL REGISTRATION: PROSPERO registration number: CRD42022308387.IMPLICATIONS FOR REHABILITATIONPilates is a good strategy for improving low back pain and is more effective than other exercise programs or no exercise.Pilates is a safe tool to apply to most of the population with low back pain.Pilates is a non-pharmacological strategy useful for counteracting low back pain.

Female athlete health domains: a supplement to the International Olympic Committee consensus statement on methods for recording and reporting epidemiological data on injury and illness in sport.

The IOC made recommendations for recording and reporting epidemiological data on injuries and illness in sports in 2020, but with little, if any, focus on female athletes. Therefore, the aims of this supplement to the IOC consensus statement are to (i) propose a taxonomy for categorisation of female athlete health problems across the lifespan; (ii) make recommendations for data capture to inform consistent recording and reporting of symptoms, injuries, illnesses and other health outcomes in sports injury epidemiology and (iii) make recommendations for specifications when applying the Strengthening the Reporting of Observational Studies in Epidemiology-Sport Injury and Illness Surveillance (STROBE-SIIS) to female athlete health data.In May 2021, five researchers and clinicians with expertise in sports medicine, epidemiology and female athlete health convened to form a consensus working group, which identified key themes. Twenty additional experts were invited and an iterative process involving all authors was then used to extend the IOC consensus statement, to include issues which affect female athletes.Ten domains of female health for categorising health problems according to biological, life stage or environmental factors that affect females in sport were identified: menstrual and gynaecological health; preconception and assisted reproduction; pregnancy; postpartum; menopause; breast health; pelvic floor health; breast feeding, parenting and caregiving; mental health and sport environments.This paper extends the IOC consensus statement to include 10 domains of female health, which may affect female athletes across the lifespan, from adolescence through young adulthood, to mid-age and older age. Our recommendations for data capture relating to female athlete population characteristics, and injuries, illnesses and other health consequences, will improve the quality of epidemiological studies, to inform better injury and illness prevention strategies.

Physical Demands of Tennis Across the Different Court Surfaces, Performance Levels and Sexes: A Systematic Review with Meta-analysis.

BACKGROUND: Tennis is a multidirectional high-intensity intermittent sport for male and female individuals played across multiple surfaces. Although several studies have attempted to characterise the physical demands of tennis, a meta-analysis is still lacking. OBJECTIVE: We aimed to describe and synthesise the physical demands of tennis across the different court surfaces, performance levels and sexes. METHODS: PubMed, Embase, CINAHL and SPORTDiscus were searched from inception to 19 April, 2022. A backward citation search was conducted for included articles using Scopus. The PECOS framework was used to formulate eligibility criteria. POPULATION: tennis players of regional, national or international playing levels (juniors and adults). EXPOSURE: singles match play. Comparison: sex (male/female), court surface (hard, clay, grass). OUTCOME: duration of play, on-court movement and stroke performance. STUDY DESIGN: cross-sectional, longitudinal. Pooled means or mean differences with 95% confidence intervals were calculated. A random-effects meta-analysis with robust variance estimation was performed. The measures of heterogeneity were Cochrane Q and 95% prediction intervals. Subgroup analysis was used for different court surfaces. RESULTS: The literature search generated 7736 references; 64 articles were included for qualitative and 42 for quantitative review. Mean [95% confidence interval] rally duration, strokes per rally and effective playing time on all surfaces were 5.5 s [4.9, 6.3], 4.1 [3.4, 5.0] and 18.6% [15.8, 21.7] for international male players and 6.4 s [5.4, 7.6], 3.9 [2.4, 6.2] and 20% [17.3, 23.3] for international female players. Mean running distances per point, set and match were 9.6 m [7.6, 12.2], 607 m [443, 832] and 2292 m [1767, 2973] (best-of-5) for international male players and 8.2 m [4.4, 15.2], 574 m [373, 883] and 1249 m [767, 2035] for international female players. Mean first- and second-serve speeds were 182 km·h-1 [178, 187] and 149 km·h-1 [135, 164] for international male players and 156 km·h-1 95% confidence interval [151, 161] and 134 km·h-1 [107, 168] for international female players. CONCLUSIONS: The findings from this study provide a comprehensive summary of the physical demands of tennis. These results may guide tennis-specific training programmes. We recommend more consistent measuring and reporting of data to enable future meta-analysts to pool meaningful data. CLINICAL TRIAL REGISTRATION: The protocol for this systematic review was registered a priori at the Open Science Framework (Registration DOI https://doi.org/10.17605/OSF.IO/MDWFY ).

Sport and exercise medicine/physiotherapy publishing has a gender/sex equity problem: we need action now!

OBJECTIVES: We aimed to determine (1) the proportion of women authors overall, in first (lead) and last (senior) author positions, (2) the proportion of women research participants and (3) the association between women in first and/or last author positions and the proportion of women research participants in original research articles and editorials/opinion pieces in four sport and exercise medicine/physiotherapy journals. METHODS: The journals evaluated were the British Journal of Sports Medicine, Journal of Orthopaedic and Sports Physical Therapy, Physical Therapy in Sport and International Journal of Sports Physical Therapy.We reviewed all original research articles and editorials/opinion pieces published in 2008, 2009, 2018 and 2019. For each, we aimed to determine the gender/sex of all authors (through gender pronouns, Google Scholar, ResearchGate, institutional profiles, personal websites, photographs and/or social media), and the gender/sex of study participants reported as 'female' or 'male' or 'women' or 'men' or 'girls' or 'boys'. RESULTS: We included 952 original studies and 219 editorials/opinion pieces. There were 5146 authors of original studies and 706 authors of editorials/opinion pieces. Compared with 2008/2009, the proportion of women as first and last authors was 3.6% (33.0% compared with 29.4%) and 4.8% (33.2% compared with 27.4%) higher respectively in 2018/2019. On average, the proportion of women participants in original studies remained largely unchanged over the 10-year period, only 10% of all participants were women in studies. CONCLUSION: Women are strikingly under-represented in first and last author positions, as are women participants in sports and exercise medicine/physiotherapy journals.

"There's definitely something wrong but we just don't know what it is": A qualitative study exploring rowers' understanding of low back pain.

OBJECTIVES: Low back pain is highly prevalent in rowing and can be associated with significant disability and premature retirement. A previous qualitative study in rowers revealed a culture of concealment of pain and injury due to fear of judgement by coaches or teammates. The aim of this study was to explore rowers' perspectives in relation to diagnosis, contributory factors, and management of low back pain. DESIGN: Qualitative secondary analysis. METHODS: We conducted a secondary analysis of interview data previously collected from 25 rowers (12 in Australia and 13 in Ireland). A reflexive thematic analysis approach was used. RESULTS: We identified three themes: 1) Rowers attribute low back pain to structural/physical factors. Most rowers referred to structural pathologies or physical impairments when asked about their diagnosis. Some participants were reassured if imaging results helped to explain their pain, but others were frustrated if findings on imaging did not correlate with their symptoms. 2) Rowing is viewed as a risky sport for low back pain. Risk factors proposed by the rowers were primarily physical and included ergometer training, individual technique, and repetitive loading. 3) Rowers focus on physical strategies for the management and prevention of low back pain. In particular, rowers considered stretching and core-strengthening exercise to be important components of treatment. CONCLUSIONS: Rowers' understanding of low back pain was predominantly biomedical and focused on physical impairments. Further education of rowers, coaches and healthcare professionals in relation to the contribution of psychosocial factors may be helpful for rowers experiencing low back pain.

A Win-Win for Sport and Exercise Medicine and Primary Care: A Qualitative Case Study of the Added Competence Model in Canada.

OBJECTIVE: To understand the unique impacts of the College of Family Physicians of Canada's (CFPC) Certificate of Added Competence (CAC) in Sport and Exercise Medicine (SEM) on the delivery of comprehensive care in Canada. DESIGN: Secondary analysis of qualitative interview data collected during a multiple case study of the impacts of the CAC program in Canada. SETTING: Six cases purposively sampled from across Canada. Each case was bound by a collective of healthcare providers who work with a defined group of patients. PARTICIPANTS: Across the cases, 48 individuals participated, including SEM and other enhanced skill family physicians, generalist family physicians, residents, specialists, and administrative staff. MAIN OUTCOME MEASURES: Qualitative descriptions of the impacts of the SEM certificate on comprehensive care provision in Canada. RESULTS: SEM certificate holders experience enhanced well-being and professional satisfaction while also benefitting comprehensive care in communities in numerous ways. That SEM certificate holders may prioritize professional interests over community healthcare needs was identified as a potential drawback. Athletes and physically active individuals have specific healthcare needs, and may constitute a significant critical mass to be considered a community unto themselves. CONCLUSIONS: The SEM certificates impact healthcare positively when holders work in collaborative models that are well aligned with local community needs. Expanding the awareness of the scope of SEM and advocacy for adequate remuneration for these services have the potential to enhance SEM contributions to comprehensive family medicine in Canada.

Small steps, strong shield: directly measured, moderate physical activity in 65 361 adults is associated with significant protective effects from severe COVID-19 outcomes.

OBJECTIVE: To determine the association between directly measured physical activity and hospitalisation, intensive care unit (ICU) admission, ventilation and mortality rates in patients with a confirmed diagnosis of COVID-19. METHODS: Directly measured physical activity data from 65 361 adult patients with a COVID-19 diagnosis from 19 March 2020 to 30 June 2021, were grouped by activity level: low (<60 min/week), moderate (60-149 min/week) and high activity (≥150 min/week). The association of physical activity levels and the risk of adverse outcomes was analysed using modified Poisson regression. We accounted for demographics and comorbidities including conditions known to influence COVID-19 outcomes, as well as patient complexity as measured by the Johns Hopkins Adjusted Clinical Group system. The regression approach was further validated with a Bayesian network model built off a directed acyclic graph. RESULTS: High physical activity was associated with lower rates of hospitalisation (risk ratio, RR 0.66, 95% CI 0.63 to 0.70), ICU admission (RR 0.59, 95% CI 0.52 to 0.66), ventilation (RR 0.55, 95% CI 0.47 to 0.64) and death (RR 0.58, 95% CI 0.50 to 0.68) due to COVID-19 than those who engaged in low physical activity. Moderate physical activity also was associated with lower rates of hospitalisation (RR 0.87, 95% CI 0.82 to 0.91), admission to ICU (RR 0.80, 95% CI 0.71 to 0.89), ventilation (RR 0.73, 95% CI 0.62 to 0.84) and death (RR 0.79, 95% CI 0.69 to 0.91). CONCLUSIONS: Adults with high and moderate physical activity levels had significantly better outcomes than those with low activity when contracting COVID-19. The apparent protective effects of regular physical activity extended to those with concomitant chronic medical conditions.
