Introduction
Olympic Weightlifting is really a sport where athletes compete to the total weight of two lifts: the snatch and the clean & jerk. The education methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a method of lifting weights for the number of other sports. One of the greatest reasons behind exploiting various lifting weights modalities such is good for power development. There are lots of 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 favorite method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks in addition to their variations) conducted from the training (Garhammer, 1993). It has traditionally been described as efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations that demand to be addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program of the athlete, some of these include movement competency, training age, sport and coaching time with athlete. The objective of this short article by Elite Performance Institute (EPI) is usually to provide a biomechanical and physiological discussion why weightlifting exercises are necessary to improve athletic performance and how they should be performed inside a training course.

Power Defined
Power has become defined as the best blend of speed and strength to produce movement (Chu 1996). Particularly, power represents light beer the athlete to produce high numbers of sort out confirmed distance. The greater power a player possesses the better the a higher level work performed (Wilson 1992). Power is really a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are lots of physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength contain a boost in muscle tissues 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 to move comprises various interrelated factors (Ackland & Bloomfield 1995). They’re; (1) muscle fibre type; (2) skill; (3) muscle insertion points; (4) lever length; (5) muscular posture; and (6) elastic energy utilisation of the series elastic component.
Olympic Weightling exercises facilitate continuing development of the center (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification UK according to the form of strength developed from each exercise, session or phase to train from the program. Therefore, the Strength & Conditioning coach can effectively plan what sort of power they wish to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is best utilised to elicit these adaptations.
Conclusion
Concern still exists for the ef?cacy of including Olympic weightlifting exercises from the lifting weights programs of athletes in sports besides weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time needed to educate yourself on the movements as a result of complexity with the lifts. 2) Deficiencies in idea of the possibility bene?ts that may be based on performing Olympic lifting exercises correctly. 3) Concern over the risk of injury caused by practicing these weightlifting movements.
It really is evident there are a great number of biomechanical important things about practicing these lifts with limited disadvantages. The biggest risk has become with the perceived danger of practicing these lifts. On the basis of the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it is usually stated with con?dence the risk of injury is really as low or less than most sports so long as there’s quali?ed supervision provided by certi?ed Strength and Conditioning coach who are trained in coaching the weightlifting movements.
