| Abstract The aim of the current study was to examine the efficacy of resisted sled-based training compared to traditional unresisted sprint training in terms of mediating improvements in speed, agility, and power during an eight-week period of in-season training in elite rugby league players. Participants were randomly separated into either resisted sled or traditional sprint-based training groups and they completed an eight-week in-season training block with training prescribed based on the group to which they were assigned. Measures of 5 m, 10 m, and 20 m sprint times in addition to countermovement jump height and 505-agility test time were measured at baseline, four-weeks and eight-weeks. For sprint-based outcomes, although both groups improved significantly, there were no statistical differences between the two training methods. However, at the eight-week time point there were significant improvements in 505-agility test (sprint group: baseline = 2.45 and eight-weeks = 2.42 s/sled group: baseline = 2.43 and eight-weeks = 2.37 s) and countermovement jump (sprint group: baseline = 39.18 and eight-weeks = 39.49 cm/sled group: baseline = 40.43 and eight-weeks = 43.07 cm) performance in the sled training group. Therefore, the findings from this investigation may be important to strength and conditioning coaches working in an elite rugby league in that resisted sled training may represent a more effective method of sprint training prescription. Introduction Rugby league represents an intermittent collision team-based sport, characterized by bouts of high intensity running, physical collisions, and tackling, with intervening periods of reduced intensity activity [1]. A rugby league therefore relies on several components of athletic aptitude, including aerobic fitness, anaerobic fitness, muscular strength, power, speed, and agility in order to compete at elite level [2]. A rugby league requires players to be able to move quickly in order to position themselves effectively in both attack and defense [3], and previous analyses have importantly shown that speed is associated with increased tackling performance and has been shown to distinguish between playing levels [1,4,5]. Furthermore, increased lower body power has been shown to be associated with increased tackling ability [5] and is similarly able to differentiate between playing standards [6]. Similarly, in regards to agility, rugby league requires players to rapidly accelerate, decelerate, and change direction in both attack and defense, and previous investigations have confirmed that agility is able to differentiate between players of different ability [7]—highlighting clearly the importance of maximizing speed, agility, and power in an elite rugby league. |
