Introduction
Olympic Weightlifting is a sport by which athletes compete for that total weight of 2 lifts: the snatch as well as the clean & jerk. Working out methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a technique of resistance training for a massive amount other sports. One of the first reasons for exploiting various resistance training modalities such is made 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 favorite method used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted in the exercise (Garhammer, 1993). It is traditionally been seen as efficient way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require to be addressed when implementing Olympic lifting exercises to the Strength & Conditioning program of your athlete, a few of these include movement competency, training age, sport and training time with athlete. The purpose of this article by Elite Performance Institute (EPI) is usually to supply a biomechanical and physiological discussion why weightlifting exercises are necessary to improve athletic performance and just how they should be performed inside a training curriculum.

Power Defined
Power continues to be thought as the suitable combination of speed and strength to generate movement (Chu 1996). Specifically, power represents light beer the athlete to generate high levels of sort out a given distance. The greater power an athlete possesses the larger the level of work performed (Wilson 1992). Power is a combination of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are several physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength incorporate a rise in muscle 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 of motion is made up of various 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 technique series elastic component.
Olympic Weightling exercises facilitate development of the middle (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Courses with regards to the form of strength developed from each exercise, session or phase of training in the program. Therefore, the force & Conditioning coach can effectively plan what sort of power to merely develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is the most suitable utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises in the resistance training programs of athletes in sports other than weightlifting. These concerns generally belong to 3 broad categories: 1) Perceived time needed to discover the movements because of the complexity of the lifts. 2) Too little idea of the possible bene?ts that can be produced from performing Olympic lifting exercises correctly. 3) Concern on the potential for injury due to practicing these weightlifting movements.
It can be evident there are a great number of biomechanical great things about practicing these lifts with limited disadvantages. The biggest risk continues to be of the perceived danger of practicing these lifts. Judging by evidence presented by Brian Hammill of the British Weightlifting Association (BWLA), it may be stated with con?dence how the risk of harm can be as low or under most sports as long as there exists quali?ed supervision furnished by certi?ed Strength and Conditioning coach who are competent in coaching the weightlifting movements.
