Does Intensive Pre-Season Strength Education Protect Rugby Players From Non-Contact Injury?

Each year the Sydney University Football Club selects a group of players for its Elite Improvement Squad to prepare for the subsequent season. For 2005 a squad of 50 was chosen which did not include any of the Club's seven Wallabies nor any of the players on Super 12 contracts. Players committed themselves to about fourteen weeks of intensive training involving six to seven sessions per week of weights, capabilities and fitness perform in spite of either being complete time students or working full time. At the conclusion of the season the Club's doctor, Katherine Rae, and physiotherapist, Keiran Cleary, jointly issued a Medical Report analysing the injury encounter of the Club's eight teams. They specifically highlighted the members of the Elite Development Squad, noting that throughout the season "the EDS squad suffered only two non get in touch with injuries, both muscle strains, which resulted in only 4 games lost to injury." Much more especially, among the 36 players who completed the complete EDS system there was "only one particular calf strain and one particular hamstring strain ... . They had no back discomfort or groin pain necessitating loss of game time." By contrast, for the Club as a whole, there have been 28 instances of low back pain, 27 hamstring injuries, 27 groin injuries and 6 quadriceps strains. Two non speak to injuries in over 1000 hours of playing time is an extraordinarily low figure in itself, and certainly by comparison with the Club's other players who accumulated more than 80 comparable injuries. The injury incidence for the Club as a whole appears to be broadly in line with that reported in a variety of scientific studies including those focussed on specialist players. It is certainly unwise to attach also a lot significance to the experience of 1 club over a single season. However the disparity in injury rates in between those in the EDS group and their group mates is so fantastic that it is quite unlikely to be attributable to mere possibility. Consequently it is essential to discover attainable motives for this very favorable outcome. I think that there have been 3 relevant factors at work: Duration and intensity of the training program An off-season involving around 90 uninterrupted training sessions creates a close to excellent opportunity for players to enhance their simple strength and fitness for rugby.Really few non-professional players would have the commitment and dedication to stick to such an exacting schedule. And extremely few professional players would have such a huge block of time available. For instance, Australian complete-time players typically participate in at least two of the three tiers of club, provincial and international rugby and are for that reason playing through most of the year. The EDS squad also had on-campus access to physiotherapists, doctors and nutritionists plus standard dietary supplementation. Hence, even although the squad members were not paid, they were education in a really professional atmosphere. Emphasis on fundamental strength development Strength and conditioning in the EDS plan was structured and administered by Martin Harland, a sports scientist who had previously worked with specialist rugby league, Australian football and basketball teams. His programs for rugby players place a high degree of emphasis on basic strength improvement and rugby-particular fitness. A distinguishing function of his method is a concentration on heavy lower body work by means of workouts such as squats, deadlifts and cleans. Use of the ScrumTruk In addition to their cost-free weights exercises the group regularly utilized the rugby specific MyoQuip ScrumTruk as a core element of their leg strength perform. Certain distinctive attributes of this apparatus may be relevant to protection against injury. Despite the fact that it performs basically the identical muscle groups as the barbell squat, the fact that the resistance is in the horizontal rather than the vertical plane implies that there is no adverse loading on the lumbar spine. It is also more quadriceps certain than the squat and workout routines efficiently the muscle tissues of the calf. But its main advantage in injury minimization might be in relation to the hamstrings. The ScrumTruk especially performs this muscle group as well as adjacent places such as the glutes, quadriceps and core stabilizers. But the most crucial impact might relate to the regularly observed significance of eccentric loading in developing the hamstrings. Both the barbell squat and the conventional leg press deliver continuous resistance. When performing these movements concentrically the muscles involved are only below really partial load as the hip and knee joints move to complete extension. By contrast the ScrumTruk's operation gives continually rising resistance throughout the exercising movement. Due to the fact of this, the muscles involved are strongly activated over the full physical exercise variety and most critically are working at close to full load at the conclusion of the movement. It would seem to follow logically that the more that muscle tissues are getting activated concentrically, the higher the eccentric load when the movement is reversed. Hence there is heavy eccentric loading on the hamstrings when they are near fully extension. The low injury incidence by Sydney University's elite education squad seems to suggest that other teams might benefit similarly by implementing a extended and intensive off-season instruction program concentrating on the development of standard decrease physique strength through complicated free weight movements and the use of the ScrumTruk. The potential improved injury outcomes are further to the very substantial strength gains from such a program. backlink build
