Introduction
Olympic Weightlifting can be a sport where athletes compete for that total weight of 2 lifts: the snatch along with the clean & jerk. The courses methods utilized in Weightlifting may also be used by Strength & Conditioning coaches as a method of lifting weights for the wide range of other sports. One of the greatest reasons for exploiting various lifting weights modalities such is good for power development. There are numerous variations on the 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 trendy method used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted from the exercise (Garhammer, 1993). It’s traditionally been seen as productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which need to be addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program of the athlete, many of these include movement competency, training age, sport and coaching time with athlete. The objective of this article by Elite Performance Institute (EPI) is usually to give you a biomechanical and physiological discussion as to why weightlifting exercises are necessary to improve athletic performance and just how they should be performed within a training course.

Power Defined
Power has become thought as the suitable blend of speed and strength to produce movement (Chu 1996). Specifically, power represents light beer the athlete to produce high numbers of process a certain distance. The harder power a sports athlete possesses the better the level of work performed (Wilson 1992). Power can be a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are numerous physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include a rise in muscle mass through hypertrophy, connective tissue 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 generally; (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 development of the guts (Strength-Speed and Speed-Strength) in the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Courses based on the kind of strength developed from each exercise, session or phase of education from the program. Because of this, 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 regarding the ef?cacy of including Olympic weightlifting exercises from the lifting weights programs of athletes in sports besides weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time forced to discover the movements as a result of complexity in the lifts. 2) Deficiencies in idea of the opportunity bene?ts which can be based on performing Olympic lifting exercises correctly. 3) Concern over the potential for injury caused by practicing these weightlifting movements.
It’s evident there are a plethora of biomechanical advantages of practicing these lifts with limited disadvantages. The biggest risk has become in the perceived danger of practicing these lifts. On the basis of evidence presented by Brian Hammill in the British Weightlifting Association (BWLA), it may be stated with con?dence that the risk of harm will be as low or below most sports provided that there exists quali?ed supervision supplied by certi?ed Strength and Conditioning coach who had been been trained in coaching the weightlifting movements.
