Introduction
Olympic Weightlifting is really a sport in which athletes compete for your total weight of two lifts: the snatch and also the clean & jerk. Working out methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a technique of strength training to get a massive amount other sports. Most significant reasons behind exploiting various strength training modalities such is perfect for power development. There are many variations on the party 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 employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted from the training (Garhammer, 1993). It is traditionally been described as effective way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations which need being addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of your athlete, a few of these include movement competency, training age, sport and coaching time with athlete. The purpose of this article by Elite Performance Institute (EPI) would be to provide a biomechanical and physiological discussion that explains why weightlifting work outs are necessary to improve athletic performance and the way they ought to be performed in a training course.

Power Defined
Power has become defined as the suitable blend of speed and strength to make movement (Chu 1996). More specifically, power represents the ability of the athlete to make high levels of work through a certain distance. The harder power an athlete possesses the better the a higher level work performed (Wilson 1992). Power is really a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are many physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength contain more muscle tissues through hypertrophy, connective tissue density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that may 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 comprises 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 standby time with the series elastic component.
Olympic Weightling exercises facilitate continuing development of the very center (Strength-Speed and Speed-Strength) from the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Courses with regards to the type of strength developed from each exercise, session or phase to train from the program. As a result, 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 regarding the ef?cacy of including Olympic weightlifting exercises from the strength training programs of athletes in sports aside from weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time necessary to discover the movements as a result of complexity from the lifts. 2) A lack of idea of the possible bene?ts that may be produced from performing Olympic lifting exercises correctly. 3) Concern in the possibility of injury resulting from these weightlifting movements.
It can be evident there’s a large number of biomechanical important things about these lifts with limited disadvantages. The biggest risk has become from the perceived danger of these lifts. Judging by the research presented by Brian Hammill from the British Weightlifting Association (BWLA), it can be stated with con?dence the risk of harm will be as low or lower than most sports provided that there exists quali?ed supervision given by certi?ed Strength and Conditioning coach who have been been trained in coaching the weightlifting movements.
