The objectives of this systematic review was to evaluate the effects of respiratory muscle training (RMT) on respiratory muscle endurance (RME) and to determine the RME test that demonstrates the most consistent changes after RMT. Electronic searches were conducted in EMBASE, MEDLINE, COCHRANE CENTRAL, CINHAL and SPORTDiscus. The PEDro scale was used for quality assessment and meta-analysis were performed to compare effect sizes of different RME tests. Twenty studies met the inclusion criteria. Isocapnic hyperpnea training was performed in 40% of the studies. Meta-analysis showed that RMT improves RME in athletes (P = 0.0007) and non-athletes (P = 0.001). Subgroup analysis showed differences among tests; maximal sustainable ventilatory capacity (MSVC) and maximal sustainable threshold loading tests demonstrated significant improvement after RMT (P = 0.007; P = 0.003 respectively) compared to the maximal voluntary ventilation (MVV) (P = 0.11) in athletes whereas significant improvement after RMT was only shown by MSVC in non-athletes. The effect size of MSVC was greater compared to MVV in studies that performed both tests. The meta-analysis results provide evidence that RMT improves RME in athletes and non-athletes and MSVC test that examine endurance over several minutes are more sensitive to improvement after RMT.

This masterclass takes a multidimensional approach to movement assessment in clinical practice. It seeks to provide innovative views on both emerging and more established methods of assessing movement within the world of movement health, injury prevention and rehabilitation. A historical perspective of the value and complexity of human movement, the role of a physical therapist in function of movement health evaluation across the entire lifespan and a critical appraisal of the current evidence-based approach to identify individual relevant movement patterns is presented. To assist a physical therapist in their role as a movement system specialist, a clinical-oriented overview of current movement-based approaches is proposed within this multidimensional perspective to facilitate the translation of science into practice and vice versa. A Movement Evaluation Model is presented and focuses on the measurable movement outcome of resultants on numerous interactions of individual, environmental and task constraints. The model blends the analysis of preferred movement strategies with a battery of cognitive movement control tests to assist clinical judgement as to how to optimize movement health across an individual lifespan.

Running-related injuries are common and are associated with a high rate of reoccurrence. Biomechanics and errors in applied training loads are often cited as causes of running-related injuries. Clinicians and runners are beginning to utilize wearable technologies to quantify biomechanics and training loads with the hope of reducing the incidence of running-related injuries. Wearable devices can objectively assess biomechanics and training loads in runners, yet guidelines for their use by clinicians and runners are not currently available. This article outlines several applications for the use of wearable devices in the prevention and rehabilitation of running-related injuries. Applications for monitoring of training loads, running biomechanics, running epidemiology, return to running programs and gait retraining are discussed. Best-practices for choosing and use of wearables are described to provide guidelines for clinicians and runners. Finally, future applications are outlined for this rapidly developing field.
