Introduction
Olympic Weightlifting is a sport by which athletes compete for the total weight of two lifts: the snatch along with the clean & jerk. The training methods utilized in Weightlifting may also be employed by Strength & Conditioning coaches as a means of strength training for any massive amount other sports. Most significant causes of exploiting various strength training modalities such is for power development. There are lots of variations on the theme of power training. Many 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 employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted from the training (Garhammer, 1993). It is traditionally been viewed as a effective way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are other important considerations which need to become addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program of an athlete, many of these include movement competency, training age, sport and training time with athlete. The objective of this article by Elite Performance Institute (EPI) is always to supply a biomechanical and physiological discussion why weightlifting exercises are helpful to improve athletic performance and exactly how they must be performed within a training course.

Power Defined
Power continues to be defined as the best mix of speed and strength to produce movement (Chu 1996). More specifically, power represents ale the athlete to produce high amounts of process a certain distance. The more power an athlete possesses the better the amount of work performed (Wilson 1992). Power is a mix 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 include a rise in muscle tissue through hypertrophy, ligament density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that could 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 many different 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 use of the series elastic component.
Olympic Weightling exercises facilitate growth and development of the very center (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Certification UK regarding the kind of strength developed from each exercise, session or phase of education from the program. As a result, the Strength & Conditioning coach can effectively plan what sort of power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is better utilised to elicit these adaptations.
Conclusion
Concern still exists for the ef?cacy of including Olympic weightlifting exercises from the strength training programs of athletes in sports aside from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time needed to educate yourself on the movements due to the complexity with the lifts. 2) Deficiencies in idea of the possibility bene?ts that could be based on performing Olympic lifting exercises correctly. 3) Concern within the potential for injury as a result of practicing these weightlifting movements.
It is evident there’s a large number of biomechanical advantages of practicing these lifts with limited disadvantages. The biggest risk continues to be with the perceived danger of practicing these lifts. On such basis as the research presented by Brian Hammill with the British Weightlifting Association (BWLA), it is usually stated with con?dence the risk of harm will be as low or below most sports as long as there is quali?ed supervision supplied by certi?ed Strength and Conditioning coach who are been trained in coaching the weightlifting movements.
