Introduction
Olympic Weightlifting is often a sport by which athletes compete for your total weight of 2 lifts: the snatch and also the clean & jerk. The courses methods utilized in Weightlifting can also be employed by Strength & Conditioning coaches as a means of lifting weights for a wide range of other sports. One of the greatest causes of exploiting various lifting weights modalities such is 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 within the exercise (Garhammer, 1993). This has traditionally been seen as an efficient way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations which need being addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of the athlete, some of these include movement competency, training age, sport and coaching time with athlete. The purpose of this short article by Elite Performance Institute (EPI) would be to give a biomechanical and physiological discussion as to the reasons weightlifting work outs are helpful to improve athletic performance and how they ought to be performed in the training course.

Power Defined
Power continues to be looked as the optimal blend of speed and strength to create movement (Chu 1996). Particularly, power represents draught beer the athlete to create high numbers of function with confirmed distance. The more power a sports athlete 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 of motion)
There are numerous physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength consist of more muscle tissue 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 motion consists of 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) in the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Courses Ireland according to the sort of strength developed from each exercise, session or phase to train within 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 as to the ef?cacy of including Olympic weightlifting exercises within the lifting weights programs of athletes in sports other than weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time required to learn the movements because of the complexity in the lifts. 2) An absence of comprehension of the possibility bene?ts that may be derived from performing Olympic lifting exercises correctly. 3) Concern on the prospect of injury as a result of doing these weightlifting movements.
It can be evident there is a large number of biomechanical advantages of doing these lifts with limited disadvantages. The biggest risk continues to be in the perceived danger of doing these lifts. On such basis as the data presented by Brian Hammill in the British Weightlifting Association (BWLA), it can be stated with con?dence that the risk of harm will be as low or less than most sports providing there is quali?ed supervision supplied by certi?ed Strength and Conditioning coach who had been been trained in coaching the weightlifting movements.
