2018
Purpose:Preconditioning strategies are considered as opportunities to optimize performance on competition day. While investigations conducted in rugby players on the effects of a morning preconditioning session already exist, additional work is warranted. The aim of this study was to monitor changes in physical and psychophysiological indicators among international Rugby-7s players following a priming exercise.Methods:In a randomized crossover-design, fourteen under-18 international Rugby-7s players completed, at 8:00am, a preconditioning session consisting of a warm-up followed by small-sided games, accelerations and 2 x 50-m maximal sprints (Experimental) or no pre-loading session (Control). Following a 2-hour break, the players performed a set of six 30-m sprints and a Rugby-7s match. Recovery-stress state and salivary stress-markers levels were assessed before the preloading session (Pre), immediately after (Post-1), before the testing session (Post-2) and after (Post-3).Results:Experimental-Control d...
