  2. 2. Case Study Overview<br />Introduction to Rugby<br />Athlete Profile/History<br />Needs Analysis – sport/position specific<br />Testing<br />Athlete’s Goals<br />S+C Considerations<br />Programming<br />Summary<br />
  3. 3. Rugby<br />Intermittent Sport- high intensity activity only accounts for 6%(backs) and 14%(forwards)-aerobic system (Duthie, 2002). <br />High levels of power are required (Duthie, 2006)<br />High levels of strength is needed for the tackle, maul, ruck, scrum and lineout (Duthie 2003)<br />
  4. 4. Rugby<br /><ul><li>Deutch et al (1998) identified that Rugby players typically sprinted 10-20 meters = develop acceleration along with agility and some work on top speed (Duthie, 2006)
  5. 5. Anaerobic power and capacity = successful performance in team sports (Tesch,P 1984)
  6. 6. The aerobic system is required to allow athletes to compete and recover over an 80min game (El-Abd, J. 2005,Tomlin and Wenger 2001, Mathews and Fox 1971) </li></li></ul><li>Athlete Profile<br />22 year old <br />loose head prop<br />Semi professional<br />Ireland U20 International<br />
  7. 7. Needs Analysis<br />
  8. 8. Needs Analysis<br />In collaboration with the teams forwards coach technical analysis was carried out on the athlete’s 2 core duties<br />The Lineout<br />The Scrum<br />
  9. 9. The Lineout Lift<br />Squat Position<br />Exercises: Back Squat <br /> Front Squat<br /> Dead Lift<br /> Catch<br />OH Movement<br />Exercises: OHS<br /> Snatch<br /> Push Prs<br /> Jerk<br /> Shr Press<br />Triple Extension <br /> Exercises: OL’s<br /> CMJ<br />

The Scrum<br />Athlete in a position with hip/knee flexed , wide base, forces coming down and through the spine<br />=Squat and it’s variations<br />Athlete uses a strong leg drive while keeping good posture<br />=Dead Lift Start Pos for OL’s<br />Athlete uses high intensity short bursts of con/iso/ecc contractions<br />=Clusters/high load/eccentric contraction/wrestling<br />

  18. 18. Sufficient time for recovery 48-72hrs (Zatsiorsky & Kraemer,2006)
  19. 19. Allows short for sessions -elevated blood TST can only last 45-60mins (Zatsiorsky & Kraemer,2006)
