ResumoIncreasing daily step counts and consuming a greater range of nutrient-dense foods weekly is the take home message from the first of this month’s featured articles from Oftedal and co-workers reporting from a study of more than 1500 individuals in a large regional Australian city. In the second feature article, Channon, Matthews and Hillier, utilising a mixed methods approach, examined the standardisation of rules of medical care at mixed martial arts events in the UK. They recommend that there is an urgent need for the development of standardised and enforceable care guidelines to ensure health of participants is not compromised. In the third feature article, Quinn’s group, utilising an observational methodology, provide coaches with sport-specific activity profiles of female rugby league players that can be used to individualise training prescription. We lead off this month’s sport and exercise medicine section, with an RCT report from Holden and colleagues. They describe the impact of isometric exercise on pain in individuals with patellar tendinopathy. Smyth and co-workers report a prospective study of health problems at the 2018, 17/U and 19/U Australian National Netball Championships with comparison of surveillance methodologies. In an observational study, Clark’s team propose injury thresholds for concussion in equestrian sports. In the first of the month’s sports injury articles, Stephens, Chapman, Tate and Warmenhoven report a case study of ACL injury recovery and the practicality of using functional principal components analysis (fPCA) and intra-athlete z-score changes for monitoring individual athlete recovery. Rommers and colleagues, in a prospective cohort study of elite youth soccer players report that age-specific anthropometric and growth-related risk factors need to be considered in injury management strategies. In a prospective study, Johnston’s team describe the relationship between subjective health complaints, sleep quantity and new injury in an endurance sport population. Mkumbuzi’s group outline the different qualities of pain associated with Achilles tendon pathology using multidimensional pain scales. Bandiera and co-workers, in the first of the physical activity articles this month, report a cluster RCT examining how psychosocial variables mediate the effect of a multicomponent intervention on screen time reduction among Brazilian students from schools in vulnerable areas. Visser’s group, using a longitudinal observational model, suggest that focusing on improving children’s perceived object control and self-reported self-esteem may increase children’s participation in physical activity. Singh and colleagues report an RCT examining the impact of activity trackers in supporting physical activity maintenance following completion of a supervised exercise intervention in breast cancer therapy. In the sports science section this month, Sheehan’s group provide a simple and novel method for analysing complex network structures in Australian Football at both team- and individual-derived metrics. Harrison’s team outline the results of a survey of strength and conditioning practitioners prescribing low volume resistance ‘priming’ exercise. They report that a wide range of priming exercise methods are used, despite limited evidence supporting these methods. Held, Behringer and Donath describe the effect of 15 sessions of blood flow restriction application with a cumulative total load of 5 h over 5 weeks produced an increase in VO2max. In the final article this month, Nie and colleagues report a cross over study examining whether exercise modality and menstrual cycle phase individually or in combination, mediate the commonly observed exercise-induced elevation in cardiac troponin T. The March 2020 issue of the Journal of Science and Medicine in Sport continues to provide a high quality mix of articles across the full spectrum of science and medicine in sport.
