Biomechanical and physiological demands of kitesurfing and epidemiology of injury among kitesurfers.
Kitesurfing is a relatively new extreme water sport that is considered a high-risk sport and has rising popularity. Kitesurfing combines aspects of several water sports, including surfing, windsurfing, and wakeboarding. With a large controllable kite and a small board, kitesurfers travel over the water surface with speeds of up to 35 knots. ⋯ Most accidents during kitesurfing reported in the literature were attributed to the inability to detach the kite from the harness. Due to technical innovations, recent studies report uncontrolled actions and unsuccessful tricks and jumps with poor landings as the main mechanisms of injuries. The main purpose of the present paper is to critically analyse the current relevant scientific literature on the biomechanical and physiological demands of kitesurfing and the epidemiology of injury among kitesurfers, in order to obtain greater insights into (i) the stresses imposed on the musculoskeletal and physiological systems by kitesurfing, and (ii) the rate, pattern, and mechanisms of kitesurfing injuries.

The aim of this systematic review was to determine whether typically developing children and adolescents (aged 3-18 years) who have participated in school-based interventions have sustained outcomes in PA, fitness, and/or FMS. ⋯ It is likely that PA is a sustainable outcome from interventions in children and adolescents, and there is reasonable evidence that interventions of longer than 1 year and interventions that utilize a theoretical model or framework are effective in producing this sustained impact. It would seem probable that FMS are a sustainable outcome in children and adolescents; however, this finding should be viewed with caution given the lack of studies and the risk of bias assessment. More research is needed to assess the sustainability of fitness interventions as this review only included a handful of studies that addressed fitness and only one of these studies found a sustained impact.
