UKSCA Case Study

  1. 1. UKSCA Case Study: U18 Football Player Chris Hattersley MSc, BSc, ASCC, CSCS, CES
  2. 2. The Athlete • 17 year old central defender completing a 2 year scholarship. • 12 months S & C experience. • Dates chosen after pre-season during his first year. • Passed medical screening and has had no major injuries.
  3. 3. Needs Analysis – Game Demands • 10-13km TD, 1-2km HID (>5.5ms-1) 1-2% in possession of the ball (Williams, 2013). • 100’s of changes of direction / repeated inefficient modes of locomotion, highlights the need for sport specific conditioning. • 30-50% of a game being carried out at >85% maximum heart rate (Akubat, & Abt, 2011). • VO2max 55-65ml-kg-min. After this level has been achieved, sport specific measures of fitness become a more important indicator of performance (e.g. Yo-Yo Test) (Wells et al 2012) .
  4. 4. Needs Analysis – Kinetics / Kinematics • High levels of strength and RFD in both eccentric and concentric actions . • Need to be efficient in the sagittal, frontal and transverse planes. (Comfort & Abrahamson, 2010). Directions of Movement Linear, lateral, vertical. Usually unilateral horizontally, bilateral vertically. Region of Force Production Triple flexed – triple extension (athletic position) unilateral & bilateral Peak Forces 6210 (N) Rate & Time of Force Production <300msc Types of muscular contraction Eccentric, concentric, ballistic, cyclical, SSC.
  5. 5. Needs Analysis – Injury Risk • 87% of injuries occur to the lower limb, most common hamstring strains, ankle sprains and knee ligament injuries (Woods, Hawkins, Hulse, & Hodson, 2002). • Previous injury is one of the key factors predisposing players to subsequent injury, with 25% being repeat injuries (Arnason et al, 2003) • Screening should focus particularly on lower limb alignment, range of motion and lumbo-pelvic hip complex (LPHC) function. • Eccentric hamstring exercises and ankle proprioception important (Junge & Dvorak, 2004).

Agility VO2 Max Power Anaerobic capacity / Repeated sprint ability Functional movement , SL stability, glute activation
  8. 8. The Programme • 3 month block which consists of two 6 week meso-cycles that run alongside the technical programme.
  9. 9. Programme Rationale • First block – Hypertrophy • Second block – Max Strength • 2-3 complementary biomotor abilities are targeted to reduce any interference effects (e.g. AMPK – Mtor Signalling). (Gamble, 2013) • Logical sequencing of physical qualities with each phase designed to ‘potentiate’ the next. (Siff, 2000). • Non-linear periodisation utilised to prevent accumulation of fatigue. (Bompa & Haff, 2009)
  10. 10. Meso-cycle Conditioning Programme
  11. 11. Meso-cycle Conditioning Programme • Fitness developed through small sided games. • Running drills only used for position specific RSA or resisted sprint training. • Resisted sprints / plyometrics are included as part of the warm up on appropriate days. • Large emphasis on developing high speed running, maximal sprinting and building muscoskelteal resilience to accels / decels and repeated change of direction.

  13. 13. Meso-cycle Strength Programme
  14. 14. Meso-cycle Strength Programme • Intensity has inverse relationship with fitness work, when one is high the other is low. • Emphasis on multi-joint movements at 85-100% 5RM (Cardinale, Newton, & Nosaka, 2011) • Large amount of muscle mass activated, high amounts of tension, moderate-high volume load. (Schoenfeld, 2010) • Along with this rest periods of 2-3 mins promotes the hypertrophy of FT fibres due to repeated high force efforts stimulating high threshold MU’s. (Cardinale, Newton, & Nosaka, 2011) *Endocrine system is still developing.

  16. 16. Programme Analysis – Micro-cycle • Training logically structured. E.g. no weight training on heavy fitness day • Training with high levels of residual fatigue is placed at the start of the week. E.g heavy eccentric strength exercises. • A specific conditioning session takes place on a Tuesday, rest tech / tac drills. • Volume is reduced Thursday & Friday to optimise physical readiness for the weekend game (Williams, 2013).
