Introduction
Olympic Weightlifting is really a sport in which athletes compete for the total weight of two lifts: the snatch and also the clean & jerk. Working out methods utilized in Weightlifting may also be used by Strength & Conditioning coaches as a method of weight training for any number of other sports. One of the primary factors behind exploiting various weight training modalities such is good for power development. There are several variations on the party theme of power training. Some 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 trendy method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks in addition to their variations) conducted within the exercise (Garhammer, 1993). It’s traditionally been described as effective way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are other important considerations that demand to become addressed when implementing Olympic lifting exercises in the Strength & Conditioning program associated with an 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 always to provide a biomechanical and physiological discussion as to why weightlifting exercises are necessary to improve athletic performance and the way they will be performed inside a exercise program.

Power Defined
Power has been thought as the best combination of speed and strength to generate movement (Chu 1996). Particularly, power represents draught beer the athlete to generate high numbers of work through a given distance. The harder power an athlete possesses the larger the amount of work performed (Wilson 1992). Power is really a combination of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are several physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength contain a rise in muscular 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) boost in intra-muscular coordination; and (5) boost in inter-muscular coordination.
Speed of movement is composed of 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 standby time with the series elastic component.
Olympic Weightling exercises facilitate continuing 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 Courses Ireland according to the sort of strength developed from each exercise, session or phase of training within the program. As a result, the Strength & Conditioning coach can effectively plan which power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is most beneficial utilised to elicit these adaptations.
Conclusion
Concern still exists regarding the ef?cacy of including Olympic weightlifting exercises within the weight training programs of athletes in sports besides weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time necessary to discover the movements due to complexity with the lifts. 2) Too little knowledge of the possibility bene?ts that may be based on performing Olympic lifting exercises correctly. 3) Concern in the prospect of injury as a result of doing these weightlifting movements.
It really is evident there’s a large number of biomechanical benefits of doing these lifts with limited disadvantages. The biggest risk has been with the perceived danger of doing these lifts. On the basis of the research presented by Brian Hammill with the British Weightlifting Association (BWLA), it can be stated with con?dence that this risk of injury can be as low or less than most sports so long as there exists quali?ed supervision given by certi?ed Strength and Conditioning coach who had been trained in coaching the weightlifting movements.
