OBJECTIVES: To quantify changes in sport-related concussion and traumatic brain injury claims in New Zealand during the first two years of the COVID-19 pandemic (i.e., 2020 and 2021). DESIGN: Population-based cohort study. METHODS: This study included all new sport-related concussion and traumatic brain injury claims that were registered with the Accident Compensation Corporation in New Zealand during 1 January 2010 to 31 December 2021. Annual sport-related concussion and traumatic brain injury claim rates per 100,000 population from 2010 to 2019 were used to fit autoregressive integrated moving average models, from which forecast estimates with 95 % prediction intervals for 2020 and 2021 were derived and compared against corresponding observed values to obtain estimates of absolute and relative forecast errors...

Wearable sensors enable down range data collection of physiological and cognitive performance of the warfighter. However, autonomous teams may find the sensor data impractical to interpret and hence influence real-time decisions without the support of subject matter experts. Decision support tools can reduce the burden of interpreting physiological data in the field and incorporate a systems perspective where noisy field data can contain useful additional signals. We present a methodology of how artificial intelligence can be used for modeling human performance with decision-making to achieve actionable decision support...

OBJECTIVES: To explore relationships between groin pain and adductor squeeze strength in male academy football players over a 14-week period. DESIGN: Longitudinal cohort study. METHODS: Weekly monitoring of youth male football players consisted of reporting groin pain and testing long lever adductor squeeze strength. Players who reported groin pain at any time during the study period were stratified into the "groin pain" group while players who did not report pain remained in the "no groin pain" group...

OBJECTIVES: To assess the association between early physical activity and post-concussion sleep quality, dizziness, and postural stability among adolescents with concussion compared to uninjured controls. DESIGN: Cross-sectional. METHODS: Adolescents ages 13-18 years assessed within 14 days post-concussion and uninjured controls. Those with concussion reported if they participated in physical activity between the concussion and assessment...

OBJECTIVES: Technologies supporting the continuous, real-time measurement of blood oxygen saturation and plasma glucose levels have improved our ability to monitor performance status. Our ability to monitor other molecular markers of performance, however, including the hormones known to indicate overtraining and general health, has lagged. That is, although a number of other molecular markers of performance status have been identified, we have struggled to develop viable technologies supporting their real-time monitoring in the body...

Measures of human motion provide a rich source of health and physiological status information. This paper provides examples of motion-based biomarkers in the form of patterns of movement, quantified physical activity, and characteristic gaits that can now be assessed with practical measurement technologies and rapidly evolving physiological models and algorithms, with research advances fed by the increasing access to motion data and associated contextual information. Quantification of physical activity has progressed from step counts to good estimates of energy expenditure, useful to weight management and to activity-based health outcomes...

OBJECTIVES: This study aimed to establish health and exercise professionals' (i) current practice of screening for pelvic floor (PF) symptoms in women within sports/exercise settings (ii) between-professional group differences in screening practice (iii) confidence and attitudes towards screening for PF symptoms and (iv) barrier/enablers towards engagement in future screening practice. DESIGN: Observational, cross-sectional survey. METHODS: Australian health and exercise professionals (n = 636) working with exercising women participated in a purpose-designed and piloted, online survey about PF symptom screening in professional practice...
