Introduction
Olympic Weightlifting is really a sport where athletes compete to the total weight of 2 lifts: the snatch as well as the clean & jerk. The education methods found in Weightlifting are also utilized by Strength & Conditioning coaches as a method of weight training to get a massive amount other sports. One of the first causes of exploiting various weight training modalities such is for power development. There are numerous variations on the party’s theme of power training. Many 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 inside the exercise (Garhammer, 1993). This has traditionally been seen as an efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations which require to become addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of the athlete, many of these include movement competency, training age, sport and coaching time with athlete. The intention of this post by Elite Performance Institute (EPI) is usually to supply a biomechanical and physiological discussion that explains why weightlifting workouts are useful to improve athletic performance and how they must be performed within a training program.

Power Defined
Power has become understood to be the perfect mixture of speed and strength to produce movement (Chu 1996). More specifically, power represents ale the athlete to produce high numbers of work through a given distance. The harder power a player possesses the greater the degree of work performed (Wilson 1992). Power is really a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are numerous physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength include an increase in muscle tissue through hypertrophy, ligament 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) increase in intra-muscular coordination; and (5) increase in inter-muscular coordination.
Speed to move comprises many different 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 technique series elastic component.
Olympic Weightling exercises facilitate development of the very center (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Certification Ireland with regards to the type of strength developed from each exercise, session or phase of training inside the program. As a result, the force & Conditioning coach can effectively plan which kind of power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is better utilised to elicit these adaptations.
Conclusion
Concern still exists regarding ef?cacy of including Olympic weightlifting exercises inside the weight training programs of athletes in sports aside from weightlifting. These concerns generally belong to 3 broad categories: 1) Perceived time forced to learn the movements because of the complexity of the lifts. 2) Deficiencies in idea of the potential bene?ts that may be derived from performing Olympic lifting exercises correctly. 3) Concern over the potential for injury resulting from practicing these weightlifting movements.
It is evident there is a great number of biomechanical great things about practicing these lifts with limited disadvantages. The biggest risk has become of the perceived danger of practicing these lifts. On such basis as the data presented by Brian Hammill of the British Weightlifting Association (BWLA), it may be stated with con?dence the risk of harm will be as low or less than most sports providing there is certainly quali?ed supervision furnished by certi?ed Strength and Conditioning coach who have been competent in coaching the weightlifting movements.
