Background: Engagement in risk behaviours adopted during university continues after graduation, increasing the risk of non-communicable diseases (NCDs). This systematic review aimed to investigate the prevalence of NCD risk behaviours amongst South African university students. Methods: PubMed and Scopus databases were searched (January 1990-Apri...

Purpose: To characterise thermoregulatory and performance responses of elite road-race athletes, while competing in hot, humid, night-time conditions during the 2019 IAAF World Athletic Championships. Method: Male and female athletes, competing in the 20 km racewalk (n=20 males, 24 females), 50 km racewalk (n=19 males, 8 females) and marathon (n=15...

Objective To review risk factors associated with acute respiratory illness (ARill) in athletes, including non-infectious ARill and suspected or confirmed acute respiratory infections (ARinf). Design Systematic review. Data sources Electronic databases: PubMed-Medline, EbscoHost and Web of Science. Eligibility criteria Original research articles...

Objective To determine the incidence of acute respiratory illness (ARill) in athletes and by method of diagnosis, anatomical classification, ages, levels of performance and seasons. Design Systematic review and meta-analysis. Data sources Electronic databases: PubMed-Medline, EbscoHost and Web of Science. Eligibility criteria Original research a...

Purpose To determine associations between thermal responses, medical events, performance, heat acclimation and health status during a World Athletics Championships in hot-humid conditions. Methods From 305 marathon and race-walk starters, 83 completed a preparticipation questionnaire on health and acclimation. Core (T core ; ingestible pill) and s...

Purpose: Optimal training for endurance performance remains a debated topic. In this case study, the training of a world-class middle-/long-distance runner over a year's duration is presented. Methods: The training is analyzed via 2 methods to define training intensity distribution (TID) (1) by physiological zones and (2) by zones based on race...

Objectives: To investigate associations between components of psychological distress and five facets of mindfulness (i.e. observing; describing; acting with awareness; non-reactivity; non-judging). Participants: Students from a university in South Africa (n=174). Methods: This cross-sectional study assessed psychological distress and mindfulness us...

Race walkers must conform to a unique gait pattern with no visible loss of contact with the ground. However, how the gait pattern affects race walking economy is unclear. We investigated the energy cost (amount of energy spent per distance unit) at different race walking velocities and over a 25 km hybrid walk. Twenty-one international-level male r...

Purpose: To provide a systematic overview of physiological parameters used to determine the training status of a trail runner and how well these parameters correlate with real-world trail running performance. Method: An electronic literature search of the PubMed and Scopus digital databases was performed. Combinations of the terms "trail run" or...

Purpose To characterise hydration, cooling, body mass loss, and core (T core ) and skin (T sk ) temperatures during World Athletics Championships in hot-humid conditions. Methods Marathon and race-walk (20 km and 50 km) athletes (n=83, 36 women) completed a pre-race questionnaire. Pre-race and post-race body weight (n=74), T core (n=56) and T sk (...

The current COVID-19 pandemic has resulted in a global health emergency of unprecedented magnitude. Most governments around the world have enforced isolation strategies in an effort to curb the spread of the virus and, in so doing, they have hopefully afforded hospitals much needed time to prepare for the high patient influx (Sarto et al., 2020). T...

This study aimed to analyse the training intensity distribution (TID) of a group of 7 world-class middle- and long-distance runners over 50 weeks using two different approaches to organise TID zones: (1) based on individual specific race pace and; (2) based on physiological parameters. Analysed training data included training volume, intensity and...

PURPOSE:: The aim of this study was to analyse the association between muscle activation patterns on oxygen cost of transport in elite race walkers over the entire gait waveform. METHODS:: Twenty-one Olympic race walkers performed overground walking trials at 14 km∙h-1 where muscle activity of the gluteus maximus, adductor magnus, rectus femoris,...

Background: Typical training programmes in elite race walkers involve high training volumes at low and moderate intensities, which have been reported to induce functional and structural adaptations at an anthropometric level. Since anthropometrical variables are closely related to movement efficiency and performance in endurance events, the aim of...

Aim: The aim of this study was to determine the relationships between biomechanical parameters of the gait cycle and race walking economy in world-class Olympic race walkers. Methods: Twenty-One world-class race walkers possessing the Olympic qualifying standard participated in this study. Participants completed an incremental race walking test sta...

Aim: The aim of this case study was to compare the competition approaches for the Race Walking World Cup and the Olympic Games of a world-class 50-km racewalker. Method: Total training volumes, intensity distribution, performance tests, high altitude stages and the evolution of his haematological values during the season were analysed. The last...
