Introduction
Olympic Weightlifting is a sport by which athletes compete for the total weight of two lifts: the snatch as well as the clean & jerk. The education methods used in Weightlifting will also be employed by Strength & Conditioning coaches as a technique of strength training to get a massive amount other sports. One of the primary reasons for exploiting various strength training modalities such is for power development. There are lots of variations on the theme of power training. A few of these training modalities include plyometrics (Wilson, Elliot & Wood 1990), assisted and resisted training (Faccioni 1993a; 1993b) and speed and acceleration drills (Cinkovich 1992). A well known method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted from the training (Garhammer, 1993). It’s traditionally been described as efficient way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations that demand to be 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 informative article by Elite Performance Institute (EPI) would be to provide a biomechanical and physiological discussion why weightlifting exercises are beneficial to improve athletic performance and the way they should be performed in the training program.

Power Defined
Power continues to be understood to be the optimal mixture of speed and strength to generate movement (Chu 1996). Particularly, power represents light beer the athlete to generate high amounts of process confirmed distance. The more power an athlete possesses the larger the amount of work performed (Wilson 1992). Power is a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are lots of physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include a boost in muscular tissues through hypertrophy, connective tissue density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that can be produced are: (1) increased recruitment of motor units; (2) increased firing rate of motor neurones; (3) synchronised firing of motor neurones; (4) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed to move is composed of a variety 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 utilisation of the series elastic component.
Olympic Weightling exercises facilitate continuing development of the very center (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Courses UK according to the form of strength developed from each exercise, session or phase of coaching from the program. Because of this, the Strength & Conditioning coach can effectively plan which power they wish 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 strength training programs of athletes in sports besides weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time required to learn the movements because of the complexity with the lifts. 2) Too little idea of the possible bene?ts that can be produced from performing Olympic lifting exercises correctly. 3) Concern in the prospect of injury caused by these weightlifting movements.
It can be evident there are a multitude of biomechanical important things about these lifts with limited disadvantages. The biggest risk continues to be with the perceived danger of these lifts. Based on the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it is usually stated with con?dence that this risk of harm can be as low or below most sports provided that there exists quali?ed supervision furnished by certi?ed Strength and Conditioning coach who have been competed in coaching the weightlifting movements.
