Wearables for Running Gait Analysis: A Systematic Review
It is well established that a contributing factor to RRI is abnormal running gait, meaning early detection of potentially harmful running gait pathologies is essential. Where biomechanics have been implicated, clinical running analysis has largely been limited to the use of subjective clinical observation or rating scales, which may not be sensitive to subtle changes in performance with training or injury

Exogenous Ketone Supplements in Athletic Contexts: Past, Present, and Future
Of particular relevance to athletes are the metabolic actions of ketone bodies to alter substrate utilisation through attenuating glucose utilisation in peripheral tissues, anti-lipolytic effects on adipose tissue, and attenuation of proteolysis in skeletal muscle. There has been long-standing interest in the development of ingestible forms of ketone bodies that has recently resulted in the commercial availability of exogenous ketone supplements (EKS).

Measures of falls efficacy, balance confidence, or balance recovery confidence for perturbation-based balance training
There is a growing interest in using perturbation-based balance training (PBT) to reduce falls. PBT is a skill training intervention that aims to improve reactive balance control in response to destabilizing perturbations in a safe and controlled environment…

Irisin is more strongly associated with leisure-time physical activity than resistin and high-density lipoprotein cholesterol are
Our aim was to analyze the relationship between serum irisin and leisure-time PA (LTPA) in a large sample of the general adult population, and secondarily, to evaluate its relationship with two PA-related biomarkers

Prevalence, frequency, adverse events, and reasons for analgesic use in youth athletes
Analgesics are commonly used in youth athletes, but estimates vary depending on type of analgesic and prevalence measure. As the majority of studies were of poor methodological quality, future high-quality research should include prospective data collection of analgesic use to understand consumption trajectories.
