Hu, X., Boisbluche, S., Philippe, K., Maurelli, O., Ren, X., Li, S., Xu, B., Prioux, J. “… The positional workload characteristics in rugby union on three acquisition days (i.e. strength, endurance, and speed days) of tactical periodization are still relatively unknown. Therefore, the primary aim of this study was to shed light on the positional external workload variables (10 Hz Global Positioning System and accelerometer microtechnology) and internal workload indicators (the session rating of perceived exertion) of players in a professional rugby union team by utilizing and comparing two tactical periodization models.  …”

Shimizu, T., Tsuchiya, Y., Ueda, H., Izumi, S., Ochi, E. “… Background Although recent studies have investigated the effects of flywheel (FW) training on muscle function, the effects of transient FW exercise on jump performance in athletes are unknown. This study examined the effects of single and repeated bouts of FW squat exercises on jump performance and muscle damage in male collegiate basketball players.  …”

Kern, J., Gulde, P., Hermsdörfer, J. “… ., 2014), the relationship between soccer experience, anticipatory activation of neck muscles, and head impact magnitude remains unknown. Therefore, the aim of this pilot study was to examine the effects of soccer expertise and neck stiffness on head impact biomechanics during header-related impacts. …”

Beckham, G, K., Martin, E., Layne, D, K., Luke, R., Mayhew, J. L. “… The backwards overhead medicine ball (BOMB) throw is commonly-used to tests this ability, but the effect of varied loading on test execution is unknown. The purpose of this study was to determine the effect of different medicine ball (MB) loads on force, velocity, and power output during the BOMB throw.  …”

The aim of this study was to assess the effect of pre-exercise HRW consumption on repeated sprint performance, lactate, and perceptual responses using a repeated sprint protocol.  …”

Edwards, S., Tahu, T., Buchanan, M., Tucker, R., Fuller, G., Gardner, A. J. “… The extent to which a ball carrier may alter their approach entering a tackle in response the tackler s body height is unknown. This exploratory study aimed to identify if, when and how, the ball carrier modified their motion when being tackled in response to tackling instructions given to the tackler.  …”
