Introduction Event details • Squash is a popular competitive sport, with over 15 million players
participating across 135 nations worldwide.
• The game is confined to an indoor area of 62.5 m2 and is played with a racket and a ball that can travel up to 230 km/h
• A match is the best of 3 or 5 games dependant on gender.
• Each game is played to 11 points. The player who scores 11 points first wins the game except that if the scorereaches 10-all, the game continues until one player leads by two points.

Needs Analysis • Stiffness (McGill, 2009)• RFD Bompa & Carrera (2005). • Deceleration (Li-I,2009).
Energy Systems • Predominantly anaerobic activity, requiring high levels of aerobic conditioning
to avoid fatigue (Majumdar et al. 2009).• Lactate levels during compertition 5 to 8 mM.l (Majumdar et al. 2009) • Elite, national standard squash players VO2max levels 60 & 55 ml.kg' min' for
males and females (Majumdar et al. 2009;Gillam et al., 1988)*****.
Squash consists of repeated, short, high-intensity, intermittent bouts. Rallies have a duration average of 5-20 seconds interspersed by shorter resting periods of about 7-8 seconds. --Exercise ratio of 2:4 --86-90% V02 max --Average blood lactate level of 8mmol.L-1
Energy systems; conclusion.Girard et al (2007) study confirms that elite squash players have high aerobic power when compared with other racquet sport players of similar standard. However it was suggested that endurance- type training has to be limited because it might induce an increase in the magnitude of the fast-to-slow shift in muscle myosin heavy chain phenotype, thus reducing strength, speed, and explosiveness (Mero et al, 1991: Girard et al, 2007).
Conditioning considerations
Distance covered in a match by elite squash players> 3,650 meters (915 meters per game) (Vučković et al, 2003).five-minute rallies have been known (Vučkovic & James, 2010).
Distance covered––short rallies 4-12sec in duration L11.50m & W10.82m––medium rallies >12 to 25sec in duration L 26.99m & W26.17m––long rallies >25sec+ Long rallies L53.24m & W51.28m Winners move less than losers due to dominating the T (Hughes & Franks, 1994).

The movement patterns and distances should be designed using match analysis data and through consultation with an advanced squash coach (Wilkinson et al, 2009).
Conditioning:2
Test 1 Fig 1 - GhostingGhosting is the art of moving around the court without the ball, training the muscles and legs to move in the court in the most efficient manner to get to the ball during match play.
Test 2 - Box SprintThis is designed to develop speed/endurance. This test requires the player to start from the back of the squash court and at the command "Go!" Run to the corner of the court.
Tests are an adaption of Majumdar, Mandal & Yadav (2009) using timed intervals instead of HR & BLT.
Drills will be used as a pre technical session exercise and as a testing measure. In the likely hood of match cancelations theses drills will be used as timed intervals to replicate game play for conditioning sessions.
Injuries
UK population-based study that reported an injury rate of 5 injuries per 1000 squash-playing sessions (Nicholl, Coleman, Williams, 1995).
Typical injuries are musculoskeletal and eyes (Sharp, 2012).
Injuries to the lower extremity are common in racquet sports (Zecher & Leach, 1995).
(Finch & Eime, 2001)
Injury;The epidemiology of the injury
• Because reoccurrence of the glenohumeral joint dislocation ranged from 47% (forty-eight of 102) to 100% (twenty-one of twenty-one) among young patients preventative measure are a must to help counter the possibility of reoccurrence (Itoi et al. 2001).
• During squash players are constantly required to accelerate the humorous using the rotator muscles of the shoulder, therefore it is vital that their joints are as prepared a possible to stabilise the humeral head within the socket safely . (Baeche &Earl, 2008).
• Studies have concluded that the incidence of glenohumeral injuries can be reduced through neuromuscular training (Sims & Spina, 2009).
• An increase in muscle cross-sectional area surrounding the joint will ad to its stability and counter the atrophy caused by disuse of the injured muscles (Sims & Spina, 2009).
• Plyometric (in nature not however not specifically) exercise will strengthen surrounding tendons and ligaments, should the correct volumes and intensities be selected for the participant (Usman et al, 2011: Verkhoshansky & Siff, 2009)
• Flexibility provides a safeguard against injury in all sports, stretching lengthens muscles and increases laxity of tendons (Hillman, 1994).
Quick overview of James injury;
The following Rehab program was designed to target James shoulders, James has already gone through early and intermediate stage of rehabilitation (Sims & Spina, 2009) and will be entering late stage rehabilitation during the current program. To be completed 2x weekly.

Complex training varies tasks and loads for efficient time utilisation and multi-faceted physical fitness (Verkhoshansky & Siff, 2009). Studies have highlighted the conjugate system as a superior method for increasing performance, however the subjects were elite and could commit to more training frequency (Robbins et al, 2009). An obvious advantage of a utilising the complex method is that the development of one motor ability contributes to the development of the others (S&V). Meaning even though James is in a maintenance phase gains should in theory arise from targeted weaknesses e.g. starting strength, agility, RFD.
Complex Training
• Chatzinikolaou et al, (2010) investigation suggest that performing an acute bout of complex training (CT) may induce transient muscle damage and marked performance deterioration for as long as 24-72hours.
• Tomljanović et al (2011) Demonstrated that TRT increased the energetic potential of trained musculature, which resulted in an overall increase in power qualities, while FT improved postural control and precise coordination.
• CT caused no significant changes anthropometrics where as the RT group's results showed a significant increase in body mass (MacDonald et al, 2012).
• CT allows for the incorporation of various modalities into a single work session, offering variability and time-efficientcy (MacDonald et al, 2012).
Further considerations when selecting exercise protocols
Microcycle and Mesocycle example
Yellow = Performance
Red = Fatigue
3:1Since the adaption of the progressive overload (Milo- system) into a fluctuating overload system training variables have been manipulated to varying work loads e.g. 3:1 Mesocycle. 3:1 ratio of intensity has been selected as the most effective method to optimise James athletic progression. (Verkhoshansky & Siff, 2009).
Bompa & Carrera, (2005).
Olympic lifting progressweek1 Week 14
James had been exposed to Olympic lifting before however failed to demon consistent technique or single bar path (i.e. two peaks in velocity).
James technique was safe and fluent by weeks 8-16 but consistency was still varied. Good enough to target the mechanisms involved.

Firstly I made the decision to design a Squash program as I previously had no understanding of the game, neither had I participated in it. Choosing an unfamiliar sport allowed me to challenge myself on the same levels as coaches/scientists in the private sector e.g. Private and Governing body (EIS) Strength & Conditioners do not get to pick their athletes.
However developed the sport of squash is, the list of articles surrounding mechanics and physiological demands are limited as the general mass of literature is from private authors stating their long term assumptions surrounding participation.
I found this set back to be of a short term hindrance which accelerated my long term gains. I began participating in the sport along side James, constantly analysing his movements and comparing them to the Pros via Youtube. Post initial testing highlighted James's weaknesses further. Understanding required fitness components for success while having a lack of literature allowed me to apply “the creative mind” developing the art of strength, an essential characteristic of the modern sports scientist (Jeffreys, 2010). Having the opportunity to step outside of my comfort zone allowed me to make and correct my own errors, an essential part of the learning process (Gravells, 2012).

The following slides represent a few testing measures or equipment I would have implemented and why…
Inverse Dynamics testing Inverse dynamic testing would have been a great means of highlighting James’s adaptions in response to the training. Increases in muscular stiffness as a protective mechanism against injury from the high GRF associated with aggressive overreaching lunges and deceleration seen in match play, while increasing his ability to reverse eccentric forces and return to the ‘T’ in reduced time and also reduce the metabolic demand on the muscles (Li-I,2009). Realistically time & equipment made this valuable insight into James’s response to the program unpractical.
