Introduction
Olympic Weightlifting is a sport in which athletes compete for your total weight of two lifts: the snatch as well as the clean & jerk. The education methods utilized in Weightlifting can also be employed by Strength & Conditioning coaches as a way of lifting weights for a massive amount other sports. One of the first causes of exploiting various lifting weights modalities such is made 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 in addition to their variations) conducted inside the weight room (Garhammer, 1993). It has traditionally been viewed as a efficient way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require to become addressed when implementing Olympic lifting exercises to the Strength & Conditioning program of the athlete, a few 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 give a biomechanical and physiological discussion why weightlifting work outs are beneficial to improve athletic performance and how they ought to be performed inside a training curriculum.

Power Defined
Power continues to be thought as the optimal blend of speed and strength to make movement (Chu 1996). Specifically, power represents light beer the athlete to make high degrees of sort out a given distance. Greater power an athlete possesses the greater the level of work performed (Wilson 1992). Power is a blend 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 consist of more muscle tissues through hypertrophy, connective tissue 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 is made up of 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 use of the series elastic component.
Olympic Weightling exercises facilitate growth and development of the center (Strength-Speed and Speed-Strength) in the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification Dublin with regards to the form of strength developed from each exercise, session or phase of coaching inside the program. Therefore, the Strength & Conditioning coach can effectively plan what sort of power they need to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is best utilised to elicit these adaptations.
Conclusion
Concern still exists regarding ef?cacy of including Olympic weightlifting exercises inside the lifting weights programs of athletes in sports apart from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time needed to educate yourself on the movements because of the complexity in the lifts. 2) An absence of knowledge of the potential bene?ts which can be based on performing Olympic lifting exercises correctly. 3) Concern over the risk of injury as a result of these weightlifting movements.
It is evident there is a plethora of biomechanical advantages of these lifts with limited disadvantages. The biggest risk continues to be in the perceived danger of these lifts. Judging by the data presented by Brian Hammill in the British Weightlifting Association (BWLA), it is usually stated with con?dence that the injury risk can be as low or below most sports providing there is quali?ed supervision given by certi?ed Strength and Conditioning coach who are trained in coaching the weightlifting movements.
