Introduction
Olympic Weightlifting can be a sport through which athletes compete for the total weight of two lifts: the snatch and the clean & jerk. The education methods utilized in Weightlifting are also utilized by Strength & Conditioning coaches as a method of lifting weights for a number of other sports. One of the primary reasons behind exploiting various lifting weights modalities such is for power development. There are several 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 trendy method accustomed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted inside the weight room (Garhammer, 1993). It is traditionally been described as efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations which need to become addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of an athlete, a few of these include movement competency, training age, sport and coaching time with athlete. The intention of this informative article by Elite Performance Institute (EPI) is to provide a biomechanical and physiological discussion that explains why weightlifting exercises are helpful to improve athletic performance and how they should be performed inside a training curriculum.

Power Defined
Power continues to be defined as the suitable blend of speed and strength to make movement (Chu 1996). More specifically, power represents light beer the athlete to make high levels of work through certain distance. The harder power a player possesses the better the degree of work performed (Wilson 1992). Power can be a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are several physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength incorporate an increase in muscle tissue through hypertrophy, connective tissue density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that could be produced are: (1) increased recruitment of motor units; (2) increased firing rate of motor neurones; (3) synchronised firing of motor neurones; (4) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of movement comprises many different 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 development of the middle (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification according to the kind of strength developed from each exercise, session or phase of coaching inside the program. As a result, the force & Conditioning coach can effectively plan which 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 for the ef?cacy of including Olympic weightlifting exercises inside the lifting weights programs of athletes in sports besides weightlifting. These concerns generally belong to 3 broad categories: 1) Perceived time necessary to educate yourself on the movements due to complexity with the lifts. 2) Deficiencies in idea of the possible bene?ts that could be produced by performing Olympic lifting exercises correctly. 3) Concern within the prospect of injury due to practicing these weightlifting movements.
It is evident you can find a great number of biomechanical important things about practicing these lifts with limited disadvantages. The biggest risk continues to be with the perceived danger of practicing these lifts. On such basis as the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it can be stated with con?dence the injury risk is really as low or below most sports providing there is certainly quali?ed supervision supplied by certi?ed Strength and Conditioning coach who are trained in coaching the weightlifting movements.
