Introduction
Olympic Weightlifting is often a sport by which athletes compete to the total weight of two lifts: the snatch and the clean & jerk. The education methods used in Weightlifting can also be employed by Strength & Conditioning coaches as a technique of lifting weights for a number of other sports. Most significant factors behind exploiting various lifting weights modalities such is perfect for power development. There are several variations on the party’s 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 popular method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted in the exercise (Garhammer, 1993). This has traditionally been viewed as a productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations that demand to become addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of an athlete, many of these include movement competency, training age, sport and coaching time with athlete. The purpose of this informative article by Elite Performance Institute (EPI) would be to give a biomechanical and physiological discussion why weightlifting exercises are helpful to improve athletic performance and how they should be performed within a exercise program.

Power Defined
Power has been thought as the best mixture of speed and strength to produce movement (Chu 1996). Specifically, power represents the ability of the athlete to produce high levels of function with certain distance. The greater power an athlete possesses the larger the level of work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are several physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength consist of more muscle mass through hypertrophy, ligament density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) which can be produced are: (1) increased recruitment of motor units; (2) increased firing rate of motor neurones; (3) synchronised firing of motor neurones; (4) surge in intra-muscular coordination; and (5) surge in inter-muscular coordination.
Speed to move comprises a variety of interrelated factors (Ackland & Bloomfield 1995). These are; (1) muscle fibre type; (2) skill; (3) muscle insertion points; (4) lever length; (5) muscular posture; and (6) elastic energy standby time with the series elastic component.
Olympic Weightling exercises facilitate growth and development of the very center (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification UK based on the sort of strength developed from each exercise, session or phase of education in the program. As a result, the Strength & Conditioning coach can effectively plan which kind of power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is best utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises in the lifting weights programs of athletes in sports aside from weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time forced to study the movements because of the complexity of the lifts. 2) Deficiencies in knowledge of the potential bene?ts which can be based on performing Olympic lifting exercises correctly. 3) Concern in the risk of injury resulting from practicing these weightlifting movements.
It can be evident there are a multitude of biomechanical important things about practicing these lifts with limited disadvantages. The biggest risk has been of the perceived danger of practicing these lifts. Based on the evidence presented by Brian Hammill of the British Weightlifting Association (BWLA), it may be stated with con?dence that the risk of injury will be as low or less than most sports so long as there is certainly quali?ed supervision given by certi?ed Strength and Conditioning coach who’ve been competed in coaching the weightlifting movements.
