“…Also other scientists (Gabbett, Stein, Kemp, & Lorenzen, 2013) emphasized to focus rugby players preparation on the physical training especially of speed-strength skills. In addition, the significance of the rugby players' speed-strength abilities is increased with increasing the intensity of the game due to a large number of short-distance accelerations and creating a large number of fast arbitrary fights (Delaney, et al, 2017).…”

Purpose: The aim of this study was to assess relationship between speed-strength abilities and technical elements of the game. Further aims was to assess the effect of specialized training on speed-strength abilities and technical elements of the game. Methods: Thirty male rugby players participated in the experiment (age 17.3±1.1 years, the body height 181.5±4.7 cm, and body weight 109.7±9.8 kg). All athletes were participants of the Ukrainian Championship under 18 age category. The study was conducted from September 2017 to June 2018. A special program of speed-strength training was developed, which contributed to the improving of technical preparedness in the competitive conditions of rugby teams. The measurement of speed-strength abilities and technical preparedness were performed before and after training programme. The relationship between speedstrength abilities and technical preparedness was assessed by Pearson correlation analysis. Results: Our study showed significant relationships between the indicators of speed-strength skills (p<0.05) and technical preparedness of rugby players (p<0.01) aged 16-18 years old. The improvement of indicators of speed-strength skills and technical preparedness under the influence of the experimental program (p<0.05) were established. Conclusions: During the speed-strength training, the effectiveness of applying the established experimental program for the development of speed-strength skills as a basis for improving the performance of technical elements for playing rugby players was proved. The test scores of the speed-strength skills significantly correlate with the indices of the technical preparedness of the athletes, justifies the necessity of their development for training of rugby players.

“…In many sports, the act of rapidly slowing the body (deceleration) is a key factor to the success of the movement [1]. The deceleration plays an important role for the players’ movement patterns in many team sports, such as soccer [2], field hockey [3], rugby [4] and others. In these team sports, running requires changes in velocity through acceleration and deceleration [5].…”

“…The maximum running intensity is established using a novel rolling mean method to analyse the raw instantaneous speed from a GPS device for a given time duration. Recent studies have established the maximum running intensities for several team sports including Australian football (Delaney et al 2017), rugby league (Delaney et al 2015) and professional rugby union (Delaney et al 2017a). However, the use of data from professional players might not be applicable for academy rugby union players (e.g., under-18 (U18)) given the difference in physical characteristics (Argus et al 2012;Darrall-Jones et al 2015) and length of matches (i.e., 70 vs. 80 min).…”

“…Previous research has used a predefined time duration (i.e., 1, 5, and 10 min) to highlight the fluctuations in running intensity during a match, with the first 10 min shown to be the most intense (Jones et al 2015;Tee et al 2017). More recently, research has investigated the maximum running intensities of international rugby union using the rolling mean method for time durations between 1 and 10 min (Delaney et al 2017a). For example, half-backs (scrum halves and fly halves) have a greater maximum running intensity at all time durations, including 1 min (184 ± 28 m•min -1 ) and 10 min (93 ± 12 m•min -1 ) than all other sub-positional groups (Delaney et al 2017a).…”

The use of 1 min intervals between 1 and 10 min is a logical analysis to use for training prescription and monitoring, as training efforts and games are often prescribed by the minute (e.g., 4 min).…”

To quantify and compare the maximum running intensities during rugby union match-play. Methods: Running intensity was quantified using micro-technology devices (S5 Optimeye, Catapult) from 202 players during 24 matches (472 observations). Instantaneous speed was used to calculate relative distance (m•min-1) using a 0.1 s rolling mean for different time durations (15 and 30 s and 1, 2, 2.5, 3, 4, 5, and 10 min). Data were analysed using a linear mixed-model and assessed with magnitude-based inferences and Cohen's d effect sizes (ES). Results: Running intensity for consecutive durations (e.g., 15 s vs. 30 s, 30 s vs. 1 min, etc.) decreased as time increased (ES = 0.48-2.80). Running intensity was lower in forwards than backs during all durations (-0.74 ±0.21 to-1.19 ±0.21). Running intensity for the second row and back row positions was greater than the front row players at all durations (-0.58 ±0.38 to-1.18 ±0.29). Running intensity for scrum-halves was greater (0.46 ±0.43 to 0.86 ±0.39) than inside and outside backs for all durations besides 15 and 30 s. Conclusions: Front rowers and scrum-halves were markedly different from other sub-positional groups and should be conditioned appropriately. Coaches working in academy rugby can use this information to appropriately overload the intensity of running, specific to time durations and positions.
