Introduction
Olympic Weightlifting is often a sport through which athletes compete for the total weight of 2 lifts: the snatch as well as the clean & jerk. Working out methods used in Weightlifting are also used by Strength & Conditioning coaches as a technique of strength training to get a great deal of other sports. One of the first reasons behind exploiting various strength training modalities such is made for power development. There are many variations on the party 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 utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted inside the exercise (Garhammer, 1993). It is traditionally been described as productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require to become addressed when implementing Olympic lifting exercises to the Strength & Conditioning program of the athlete, some include movement competency, training age, sport and training time with athlete. The objective of this informative article by Elite Performance Institute (EPI) is to give a biomechanical and physiological discussion as to the reasons weightlifting work outs are useful to improve athletic performance and the way they must be performed in the exercise program.

Power Defined
Power has been thought as the optimal blend of speed and strength to create movement (Chu 1996). Particularly, power represents light beer the athlete to create high amounts of work through certain distance. Greater power a player possesses the greater the amount of work performed (Wilson 1992). Power is often a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are many physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include an increase in muscle mass 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) surge in intra-muscular coordination; and (5) surge in inter-muscular coordination.
Speed to move is made up of a number 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 utilisation of the series elastic component.
Olympic Weightling exercises facilitate growth and development of the guts (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Certification regarding the sort of strength developed from each exercise, session or phase of coaching inside the program. Because of this, the Strength & Conditioning coach can effectively plan which power to merely 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 inside the strength training programs of athletes in sports other than weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time needed to discover the movements as a result of complexity of the lifts. 2) Too little comprehension of the possible bene?ts that can be produced by performing Olympic lifting exercises correctly. 3) Concern over the prospect of injury as a result of these weightlifting movements.
It can be evident there are a plethora of biomechanical important things about these lifts with limited disadvantages. The biggest risk has been of the perceived danger of these lifts. Judging by the research presented by Brian Hammill of the British Weightlifting Association (BWLA), it could be stated with con?dence that this risk of injury will be as low or under most sports so long as there exists quali?ed supervision supplied by certi?ed Strength and Conditioning coach who have been trained in coaching the weightlifting movements.
