“…An evaluation of running intensity and energy demands in Rugby-7s resulted in a recommendation that training drills should replicate the physiological demands experienced in matches 31 32. Earlier substitution of fatigued players in matches may also help to reduce the incidence of injuries; therefore, the use of rolling substitutions, which is being trialled by World Rugby, could contribute to a reduction in fatigue levels.…”

The incidence of injury in Rugby-7s suggests that teams require squads of around 20 players for a Sevens World Series. The higher incidence of injury in the second half of matches is probably the result of player fatigue; therefore, injury prevention strategies for teams and the Governing Body should address this issue. The results presented support the World Rugby trial allowing 'rolling substitutes' during Sevens World Series matches, as this approach may help to mitigate the effects of player fatigue during the second half of matches.

“…As a result, the acceleration/deceleration demands of this position are substantially lower than that of halves and hookers (Table 3) If athletes are to be adequately prepared for the most intense periods of competition, training prescription should account for the acceleration-based running requirements common to rugby league. The novel methodology of the present study may attenuate this implication, in comparison to that of previous research, where the metabolic power method was used to describe the mean Pmet sustained in range of team sports, such as rugby sevens (~10 W·kg -1 ) 11 , soccer (~8 W·kg -1 ) 9 , rugby league (~9 W·kg -1 ) 12 and AFL (~10 W·kg -1 ) 10 . However, these values represent whole-match averages, and fail to account for the peaks in running intensity imposed on players throughout a match.…”

“…Recently, Furlan et al 11 utilized a 2-min moving average, to determine the peak periods of Rugby Sevens performance. The authors observed that relative distance underestimated the intensity of the identified peak period when compared to the Pmet, calculated using the methods of Gray 21 , which suggests the incorporation of acceleration-based methods are necessary when quantifying team sport movement demands.…”

“…However, these values represent whole-match averages, and fail to account for the peaks in running intensity imposed on players throughout a match. Furlan et al 11 observed that peak Pmet for a 2-min moving average was significantly greater than the average of the entire period. In the present study, large increases in Pmet were observed between the 10-min moving average and all moving averages <5 min in duration (ES 1.21-1.83).…”

Rugby league involves frequent periods of high-intensity running including acceleration and deceleration efforts, often occurring at low speeds. Purpose: To quantify the energetic cost of running and acceleration efforts during rugby league competition to aid in prescription and monitoring of training. Methods: Global Positioning System (GPS) data were collected from 37 professional rugby league players across two seasons. Peak values for relative distance, average acceleration/deceleration and metabolic power (Pmet) were calculated for ten different moving average durations (1-10 min), for each position. A mixed-effects model was used to assess the effect of position for each duration, and individual comparisons were made using a magnitude-based inference network. Results: There were almost certainly large differences in relative distance and Pmet between the 10-min window and all moving averages <5 min in duration (ES = 1.21-1.88). Fullbacks, halves and hookers covered greater relative distances than outside backs, edge forwards and middle forwards for moving averages lasting between 2-10 min. Acceleration/deceleration demands were greatest in hookers and halves compared to fullbacks, middle forwards and outside backs. Pmet was greatest in hookers, halves and fullbacks compared to middle forwards and outside backs. Conclusions: Competition running intensities varied by both position and moving average duration. Hookers exhibited the greatest Pmet of all positions, due to high involvement in both attack and defence. Fullbacks also reached high Pmet, possibly due to a greater absolute volume of running. This study provides coaches with match data that can be used for the prescription and monitoring of specific training drills.

“…Instead of observing relative running distance over a whole game, peak relative running distance over shorter game intervals (e.g. a 2 min period) or metabolic power may be used as more discriminating measures (Furlan et al, 2015).…”

To inform recruitment, selection, training and testing of male and female rugby sevens players game running movement patterns and physical characteristics were quantified across Junior, Senior and Elite playing levels. Anthropometric and physical testing (40 m sprint, vertical jump, Yo-Yo IR1) occurred prior to players' national championships or international tournaments (n=110 players), while game movements were obtained via GPS (n=499 game files). The game movements of male players were similar across playing levels except for number of impacts >10g which were two-to four-fold higher in Elite (25.0 ± 11.2 impacts.game -1 ; mean ± SD), than Junior (6.3 ± 3.5) and Senior (11.8 ± 6.6) players. In men, there were fewer substantial correlations between on-and off-field measures which may reflect similar physical attributes across playing levels, and that other (strength, technical or tactical) factors may better differentiate these players. In females, Elite players had more favourable on-and off-field performance measures than Juniors and Seniors, with moderate to strong correlations between on-and off-field variables. Female players should benefit from additional fitness training, while male players need to balance fitness with other technical and tactical factors.

Running-Intensity Fluctuations in Elite Rugby Sevens Performance

Abstract: The findings suggest that running intensity varies between and within halves; however, the index used will influence both the magnitude and the temporal identification of peak periods.
