Introduction
Olympic Weightlifting is a sport in which athletes compete for the total weight of 2 lifts: the snatch and also the clean & jerk. The courses methods used in Weightlifting will also be utilised by Strength & Conditioning coaches as a way of resistance training for any massive amount other sports. One of the greatest causes of exploiting various resistance training modalities such is good for power development. There are numerous 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 well known method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted inside the training (Garhammer, 1993). This has traditionally been viewed as a efficient of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations that demand to be addressed when implementing Olympic lifting exercises to the Strength & Conditioning program associated with an athlete, a few of these include movement competency, training age, sport and training time with athlete. The intention of this article by Elite Performance Institute (EPI) is to supply a biomechanical and physiological discussion why weightlifting workouts are necessary to improve athletic performance and just how they will be performed within a exercise program.

Power Defined
Power continues to be understood to be the suitable mix of speed and strength to generate movement (Chu 1996). More specifically, power represents ale the athlete to generate high amounts of function with a given distance. The harder power a player possesses the greater the degree of work performed (Wilson 1992). Power is a mix of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are numerous physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength incorporate a boost in 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) boost in intra-muscular coordination; and (5) boost in inter-muscular coordination.
Speed of movement consists of a number 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 center (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Courses Dublin with regards to the type of strength developed from each exercise, session or phase of education inside the program. Because of this, the Strength & Conditioning coach can effectively plan which power to merely develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is better utilised to elicit these adaptations.
Conclusion
Concern still exists regarding the ef?cacy of including Olympic weightlifting exercises inside the resistance training programs of athletes in sports besides weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time forced to study the movements due to the complexity with the lifts. 2) A lack of knowledge of the possibility bene?ts which can be based on performing Olympic lifting exercises correctly. 3) Concern in the potential for injury resulting from performing these weightlifting movements.
It’s evident there is a plethora of biomechanical advantages of performing these lifts with limited disadvantages. The biggest risk continues to be with the perceived danger of performing these lifts. Judging by the evidence presented by Brian Hammill with the British Weightlifting Association (BWLA), it is usually stated with con?dence that this injury risk is really as low or under most sports so long as there exists quali?ed supervision provided by certi?ed Strength and Conditioning coach who had been been trained in coaching the weightlifting movements.
