Article
Full-text available
Women rugby players are participating in the sport at the highest levels to date. However, despite this increase in participation, sports sciences and sports medicine/sports physiotherapy (SEMS) research output has not mirrored this increase. Females have hormonally mediated anatomical and physiological profiles, which may have implications for rug...
Article
Objective To evaluate the construct validity (structural validity and hypothesis testing), reliability (test–retest reliability, measurement error and internal consistency) and minimal important change (MIC) of the 13-item TENDINopathy Severity assessment–Achilles (TENDINS-A). Methods Participants with Achilles pain completed an online survey incl...
Conference Paper
Full-text available
Introduction We evaluated construct validity (structural validity and hypothesis-testing) and reliability (test-retest reliability, measurement error and internal consistency) of the new TENDINopathy Severity assessment-Achilles (TENDINS-A), which is the only outcome measure with adequate content validity for assessment of disability in Achilles te...
Article
OBJECTIVE: To explore whether people with lower-limb tendinopathy have reduced relative conditioned pain modulation (CPM) when compared to nontendinopathy controls. DESIGN: Systematic review with individual participant data (IPD) meta-analysis. LITERATURE SEARCH: Eight databases were searched until August 29, 2022. STUDY SELECTION CRITERIA: Cross-s...
Preprint
Objectives: Evaluate the construct validity (structural validity and hypothesis-testing), reliability (test-retest reliability, measurement error and internal consistency) and minimal detectable change (MDC) of the 13-item TENDINopathy Severity assessment Achilles (TENDINS A). Methods: Participants with Achilles pain completed an online survey: dem...

Football (soccer) is a very popular team sport among African women and girls, with player numbers continuing to rise at all levels of the sport. Whereas the participation in football and associated injuries are on the rise, there are not enough sports and exercise medicine (SEM) personnel to attend to these women football players. While Africa may...
Article
Full-text available
OBJECTIVE: To develop a new patient-reported outcome measure (PROM) assessing TENDINopathy Severity of the Achilles (TENDINS-Achilles) and evaluate its content validity. DESIGN: Mixed-methods, modified Delphi. METHODS: We performed 1 round of semistructured one-on-one interview responses with professionals and patients, for initial item generation....
Article
Full-text available
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)...
Article
Full-text available
Athlete health and wellbeing requires a holistic, multidimensional approach to understanding, supporting, and treating individual athletes. Building more supportive, inclusive, and equitable environments for the health and wellbeing of women and gender expansive people further requires gender-responsive approaches that promote broader cultural chan...
Article
Despite cross-cultural differences in knowledge and attitudes toward menstruation, most studies on menstruation in women’s sport have been conducted in high-income countries, such as in Europe, and none have been conducted in Africa. The aim of this study was to explore the knowledge, attitudes, and behaviors of African elite women football players...

Article
Full-text available
Background: Schoolboy rugby is a popular sport which forms the bedrock of rugby development in many African countries, including Zimbabwe. With burgeoning talent identification programmes, the development of multi-dimensional, logically- validated, and reliable test batteries is essential to inform the objective selection of potentially talented yo...
Article
Background: The menstrual cycle is a normal biological process in women and girls. However, it is often the reason why they tend to be excluded from football medicine research. Consequently, our understanding of the menstrual cycle and football performance is still limited, especially in African women football players. Aim: The study aimed to ex...
Article
Background: Systematic analyses of injuries, illnesses or medication use and their risk factors among female African athletes are scarce, which has implications for management of these athletes. Aim: This prospective cohort study analysed the incidence and characteristics of injuries, illnesses and medication use during the 2020 COSAFA Women's C...
Article
Full-text available
The mechanisms of pain in tendinopathy are unclear. Current theories implicate tendon structural changes, neovascularisation, inflammation or changes in central pain processing. As with other types of musculoskeletal pain, tendon pain has high interindividual variability and, as with other types of pain, this could be attributed to genetic variatio...
Article
Background: Altered central pain mechanisms is a feature of other chronic pain states and upper limb tendinopathies. It is uncertain whether the same applies to chronic Achilles tendinopathy (AT). Objective: To investigate altered central pain mechanisms in chronic AT by assessing conditioned pain modulation (CPM) in recreational athletes with and...
Article
Full-text available
Background Achilles tendinopathy (AT) is associated with pain and altered ultrasound (US) and colour Doppler (CD) findings. However, the relationship between them is equivocal. Perhaps because previous studies have only used the VISA‐A scale as the measure of tendon pain. Objective To determine the relationship between tendon US and CD findings an...
Article
Full-text available
Objectives: The main assessment tool for Achilles tendinopathy (AT) is the VISA-A. However, the VISA-A only assesses the physical impairments that result from tendon pain. This study sought to describe and assess tendon pain using other multidimensional pain scales; the short forms of the McGill pain questionnaire (sf-MPQ) and the Brief Pain Inven...
Article
The decline in skeletal muscle regenerative capacity with age is partly attributed to muscle stem cell (satellite cell) dysfunction. Recent evidence has pointed to a strong interaction between myoblasts and fibroblasts, but the influence of age on this interaction is unknown. Additionally, while the native tissue environment is known to determine t...

Full-text available
The use of medications by football players in many populations is known to be high. Data on African players are scarce. Objective. To determine the magnitude of use of non-steroidal anti-inflammatory drugs (NSAIDs) and nutritional supplements by Zimbabwean football players. Methods. We conducted a cross-sectional study during the 2011/2012 Premier...

Objective: To determine the histological effects of different frequencies of loading in a healing Achilles tendon following partial rupture. Design: Experimental laboratory study. Setting: University of Zimbabwe, Department of Physiology, Animal house. Subjects: Sixty female Sprague-Dawley rats. Intervention: Partial tenotomies of the righ...
