Association Between Success and Unsuccess Rates on Technical Skills and Physical Qualities in Rugby Players.

Purpose: Although physical and technical performance are both fundamental in rugby union teams, the association between these variables in sub-elite players is limited. This study investigated the association between the rate of success and unsuccess in technical skills throughout a season with physical quality variables in sub-elite rugby players. Methods: Twenty-five sub-elite rugby union players (age: 26.4 ± 3.8 years; body mass: 99.68 ± 14.34 kg; height: 1.81 ± 0.07 m) completed the following assessments: (i) broad jump; (ii) 10- and 30-meters sprint speed; (iii) 5-10-5 test; (iv) 1 RM of bench press, chin-up and squat and (v) Yo-Yo fitness test. The rate of success and unsuccess in tackles, attacking rucks and carries were measured during a season. Results: We found that: (i) higher success rates in carries were associated with faster speeds and greater broad jump distance; (ii) higher unsuccess rates in tackles were associated with lower 1 RM chin-up. When controlling for playing position, (iii) higher success rates in carries were associated with 30-meters speed and broad jump distance; (iv) higher success rates in tackles were associated with higher 1 RM chin-up; and (v) higher unsuccess rates in tackles were associated with lower 1 RM chin-up. Conclusions: Success and unsuccess rates in attacking rucks and success in carries were not associated with physical qualities. Therefore, training programs that improve speed, lower limb power and upper limb maximal strength should receive greater attention when seeking to achieve greater success in trying to break the opponent's defensive line and stop the ball carrier.

Physical and performance indicators between backs and forwards in a subelite Rugby Union Team.

BACKGROUND: Backs and forwards have different physical and performance demands in Rugby Union, which are well documented in elite teams. However, in subelite teams, this comparison is scarce. The aim of study was to compare physical and performance indicators during matches in backs and forwards from a subelite Rugby Union Team. METHODS: Twenty-five professional rugby athletes (backs, N.=12; forwards, N.=13) from a subelite team were evaluated for: 1) body mass and height; 2) sprinting speed of 10 meters; 3) sprint momentum; 4) 1RM of bench press, chin-up and squat exercises; and 5) yo-yo fitness test. Performance indicators during matches (number of passes, carries, tackles, attacking rucks and ball possessions) were evaluated. A Student's t-test was used to compare variable between positions. RESULTS: We found that forwards are taller (P=0.01), heavier (P<0.001), have stronger upper limbs (P=0.02), perform more tackles (P<0.001) and participate in more attacking rucks (P<0.001), while backs are faster (P=0.005), have higher sprint momentum (P<0.001), aerobic power (P=0.01) and have more ball possessions (P=0.02). CONCLUSIONS: This study demonstrated that backs and forwards from a subelite national team have different physical characteristics and perform different actions during the matches.
