Introduction
Olympic Weightlifting is often a sport through which athletes compete to the total weight of two lifts: the snatch along with the clean & jerk. The training methods used in Weightlifting are also utilised by Strength & Conditioning coaches as a technique of resistance training for the massive amount other sports. One of the primary reasons for exploiting various resistance training modalities such is made for power development. There are lots of variations on the theme of power training. Some training modalities include plyometrics (Wilson, Elliot & Wood 1990), assisted and resisted training (Faccioni 1993a; 1993b) and speed and acceleration drills (Cinkovich 1992). A popular method used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted from the exercise (Garhammer, 1993). It has traditionally been described as efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations which require to become addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program of an athlete, some of these include movement competency, training age, sport and coaching time with athlete. The intention of this short article by Elite Performance Institute (EPI) is usually to supply a biomechanical and physiological discussion as to why weightlifting training is beneficial to improve athletic performance and exactly how they must be performed within a training course.

Power Defined
Power has been thought as the optimal mixture of speed and strength to make movement (Chu 1996). More specifically, power represents draught beer the athlete to make high numbers of work through confirmed distance. The greater power an athlete possesses the higher the a higher level work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are lots of physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength contain a boost in muscle mass through hypertrophy, ligament density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that may be produced are: (1) increased recruitment of motor units; (2) increased firing rate of motor neurones; (3) synchronised firing of motor neurones; (4) increase in intra-muscular coordination; and (5) increase in inter-muscular coordination.
Speed of motion comprises a number of interrelated factors (Ackland & Bloomfield 1995). These are generally; (1) muscle fibre type; (2) skill; (3) muscle insertion points; (4) lever length; (5) muscular posture; and (6) elastic energy technique series elastic component.
Olympic Weightling exercises facilitate progression of the middle (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification Ireland with regards to the kind of strength developed from each exercise, session or phase of training from the program. Because of this, the Strength & Conditioning coach can effectively plan which power they need to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is best utilised to elicit these adaptations.
Conclusion
Concern still exists regarding the ef?cacy of including Olympic weightlifting exercises from the resistance training programs of athletes in sports other than weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time necessary to discover the movements due to complexity with the lifts. 2) A lack of comprehension of the possibility bene?ts that may be based on performing Olympic lifting exercises correctly. 3) Concern on the prospect of injury caused by doing these weightlifting movements.
It can be evident there are a multitude of biomechanical great things about doing these lifts with limited disadvantages. The biggest risk has been with the perceived danger of doing these lifts. On such basis as the research presented by Brian Hammill with the British Weightlifting Association (BWLA), it may be stated with con?dence how the risk of injury is as low or below most sports provided that there is quali?ed supervision provided by certi?ed Strength and Conditioning coach who had been competed in coaching the weightlifting movements.
