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.

Needs Analysis – Game Demands

• 10-13km TD, 2-3km HID (>15km/h) 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) .

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.

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).

The Programme• 3 month block which consists of two 6 week meso-cycles that run

alongside the technical programme.

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)

Meso-cycle Conditioning Programme• Focus on developing RSA through sport specific running drills while maintaining

aerobic conditioning with SSG’s. • Speed / plyo work included in warm up.

Meso-cycle Strength Programme

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.

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).

Interaction with staff & players

• With technical coaches on a daily basis to plan training load.

• End stage rehab or movement screening with physios.

• Daily presentation of data to players, reports every 6 weeks, open door policy.
