Prevalence and risk factors of running-related injuries in Korean non-elite runners: a cross-sectional survey study.
CONCLUSIONS: To avoid running-related injuries, runners should be careful when increasing weekly mileage. Moreover, runners with previous exercise experience may need to approach running more cautiously. Setting goals and pursuing longer-distance running events may be motivating, but at the same time, can increase the risk of running-related injuries.

Effects of circuit resistance training on muscle power, functional agility, and bones' mineral content in people with spinal injury.
CONCLUSIONS: Therefore, one can consider that CRT is an alternative to develop the upper limbs muscle power and functional agility. Together, all these variables may imply an overall improvement of the functional capacity in people with SCI. Additionally, these 12 weeks of CRT were responsible for helping the maintenance of lean mass, bone mineral content and T-score in this study's sample.

CONCLUSIONS: Fitness watches relying on optical measures of HR underestimate HR compared to criterion measures during moderate intensity exercise. Despite providing a more accurate measure of HR, a chest-worn monitor does not provide a more accurate estimate of EE compared to fitness watches. The Fitbit provided the most accurate measure of EE when compared to the Polar Ignite watch and chest-worn device.

Technical and tactical effectiveness is related to time-motion performance in elite rugby.
CONCLUSIONS: Technical and tactical performance affects running activities differently for forwards and backs. During training sessions, coaches should stimulate forwards to be more active (i.e. to complete more metres/minute, more explosive distance) and backs to control more the defensive structure (i.e., less %high-speed running and less distance covered above 14km/h and 17km/h speed). A progression from short to long game sequences, that quickly recreate the game plan and keep the momentum, could stimulate technical and tactical performance, as well as physical conditioning.
