Introduction
Olympic Weightlifting is often a sport through which athletes compete for your total weight of two lifts: the snatch along with the clean & jerk. The education methods utilized in Weightlifting are also employed by Strength & Conditioning coaches as a technique of weight training for any massive amount other sports. Most significant reasons for exploiting various weight training modalities such is perfect for power development. There are many variations on the party’s 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 favorite method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted within the exercise (Garhammer, 1993). This has traditionally been seen as productive way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations which require being addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program associated with an athlete, a few of these include movement competency, training age, sport and training time with athlete. The objective of this article by Elite Performance Institute (EPI) is usually to supply a biomechanical and physiological discussion as to the reasons weightlifting exercises are beneficial to improve athletic performance and just how they should be performed in a exercise program.

Power Defined
Power has been defined as the perfect mixture of speed and strength to make movement (Chu 1996). Specifically, power represents draught beer the athlete to make high amounts of function with certain distance. The greater power a player possesses the greater the a higher level work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are many physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength consist of a boost in muscle tissues 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of movement is composed of many different interrelated factors (Ackland & Bloomfield 1995). They are; (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 growth and development of the guts (Strength-Speed and Speed-Strength) from the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Courses according to the sort of strength developed from each exercise, session or phase of coaching within the program. Consequently, the Strength & Conditioning coach can effectively plan what type of power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is the most suitable utilised to elicit these adaptations.
Conclusion
Concern still exists regarding ef?cacy of including Olympic weightlifting exercises within the weight training programs of athletes in sports aside from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time necessary to learn the movements due to complexity from the lifts. 2) An absence of idea of the potential bene?ts which can be produced by performing Olympic lifting exercises correctly. 3) Concern over the possibility of injury resulting from these weightlifting movements.
It can be evident there is a multitude of biomechanical great things about these lifts with limited disadvantages. The biggest risk has been from the perceived danger of these lifts. Judging by the evidence presented by Brian Hammill from the British Weightlifting Association (BWLA), it can be stated with con?dence the risk of injury is as low or below most sports so long as there’s quali?ed supervision supplied by certi?ed Strength and Conditioning coach who had been competed in coaching the weightlifting movements.
