“…The BURST has been previously shown to induce mean values of 160 beats.min -1 for heart rate and 4.6 mmol.l -1 for blood lactate while distance travelled (7078 m) has been validated against match play demands derived from time-motion analysis (6418 m). The time spent performing contact events was the same for both match play and the BURST (9.9%) (Roberts et al, 2010). The coefficient of variation over two trials for heart rate, mean Performance Test times and 15-m sprint times during the BURST were 2.2, 1.3 and 0.9%, respectively (Roberts et al, 2010).…”

“…The BURST is a rugby union-specific match-play protocol derived from physical demands data for elite rugby union forwards (Roberts et al, 2008). The exercise requirements have been described in detail elsewhere (Roberts, Stokes, Weston, & Trewartha, 2010). Briefly, the protocol comprises 16 x 315-s exercise periods grouped into 4 x 21-min blocks ( Figure 1).…”

In this study, we investigated the effect of ingesting carbohydrate alone or carbohydrate with protein on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g · kg body mass(-1) · h(-1)) or carbohydrate with protein (0.4 g · kg body mass(-1) · h(-1)) before, during, and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase: before, 258 ± 171 U · L(-1) vs. 24 h after, 574 ± 285 U · L(-1); myoglobin: pre, 50 ± 18 vs. immediately after, 210 ± 84 nmol · L(-1); P < 0.05) and muscle soreness (1, 2, and 3 [maximum soreness = 8] for before, immediately after, and 24 h after exercise, respectively) increased. Leg strength and repeated 6-s cycle sprint mean power were slightly reduced after exercise (93% and 95% of pre-exercise values, respectively; P < 0.05), but were almost fully recovered after 24 h (97% and 99% of pre-exercise values, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein.

In this study, we investigated the effect of ingesting carbohydrate alone or with caffeine on performance of a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced trial order, eight male rugby union forwards ingested either placebo or carbohydrate (1.2 g x kg(-1) body mass x h(-1)) before and during a rugby union-specific protocol, with pre-exercise caffeine ingestion (4 mg x kg(-1)) before one of the carbohydrate trials (carbohydrate + caffeine). The intermittent exercise protocol included walking, jogging, and cruising at pre-determined intensities, simulated contact events, a sustained high-intensity test of speed and agility (Performance Test), and a 15-m sprint. Ratings of perceived exertion (RPE) were recorded every 5 min and a motor skills test was performed after each 21-min block. Performance Test times were not significantly different between trials but the likelihood of 2% improvements for carbohydrate + caffeine over placebo and carbohydrate were 98% and 44%, respectively. For carbohydrate + caffeine, 15-m sprints were faster than for placebo (P=0.05) and the motor skills test was performed faster in the carbohydrate + caffeine trial than the carbohydrate and placebo trials (P < 0.05), while RPE was lower in the carbohydrate + caffeine trial than the carbohydrate and placebo trials (P < 0.05). The results indicate a likely benefit to rugby performance following co-ingestion of carbohydrate and caffeine.

Background. Rugby union is a team sport with a high amount of physical contact during match play. The physical performance and anthropometric characteristics required, differ based on the playing position. Objectives. The objective of this systematic review was to relate anthropometric properties with physical performance parameters in Rugby union backs and forwards across different playing levels of Tier 1 nations. Methods. Two electronic searches were performed in MEDLINE on the PubMed and on BISp (German Federal Sports Science Institute) databases from August 2016 to July 2017. All experimental study types in English and German were assessed for eligibility. Inclusion criteria were 15-a-side senior male backs and forwards, with anthropometric and/or physical performance data. Results. In n = 7 studies out of 12 selected, the elite forwards were significantly taller than the elite backs (p < 0.05). This accounted not for lower playing levels. Across all levels the forwards were significantly heavier than the backs. Significantly lower body fat percentages for the backs demonstrated n = 5 out of 6 studies. Consequently, backs were more ectomorphic than forwards. Backs reached significantly lower sprint velocities over short distances and higher ones over longer distances (10 to 40 m). Conclusion. Anthropometric parameters adapt to physical performance requested. In strength and endurance test situations heavier players may be underestimated postulating careful interpretation of those results to avoid misleading conclusion.
