Introduction
Olympic Weightlifting is often a sport through which athletes compete for the total weight of two lifts: the snatch as well as the clean & jerk. Working out methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a technique of weight training for any wide range of other sports. One of the primary reasons for exploiting various weight training modalities such is for power development. There are numerous variations on the theme of power training. A few 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 popular method used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted from the training (Garhammer, 1993). This has traditionally been seen as an productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require being 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 informative article by Elite Performance Institute (EPI) is to provide a biomechanical and physiological discussion as to why weightlifting exercises are beneficial to improve athletic performance and just how they ought to be performed inside a training course.

Power Defined
Power has become thought as the optimal mixture of speed and strength to make movement (Chu 1996). More specifically, power represents draught beer the athlete to make high levels of process certain distance. The harder power a player possesses the larger the a higher level work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are numerous physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength consist of more muscle mass through hypertrophy, ligament 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of motion consists of various interrelated factors (Ackland & Bloomfield 1995). They 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 growth and 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 Dublin with regards to the kind of strength developed from each exercise, session or phase of education from the program. Therefore, the force & Conditioning coach can effectively plan which power they need to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is most beneficial utilised to elicit these adaptations.
Conclusion
Concern still exists for the ef?cacy of including Olympic weightlifting exercises from the weight training programs of athletes in sports apart from weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time needed to educate yourself on the movements because of the complexity from the lifts. 2) Too little idea of the possible bene?ts which can be produced from performing Olympic lifting exercises correctly. 3) Concern within the prospect of injury resulting from these weightlifting movements.
It can be evident there’s a multitude of biomechanical benefits of these lifts with limited disadvantages. The biggest risk has become from the perceived danger of these lifts. On the basis of the research presented by Brian Hammill from the British Weightlifting Association (BWLA), it could be stated with con?dence that this risk of harm can be as low or lower than most sports as long as there exists quali?ed supervision provided by certi?ed Strength and Conditioning coach who have been competent in coaching the weightlifting movements.
