Introduction
Olympic Weightlifting is really a sport in which athletes compete for the total weight of two lifts: the snatch and the clean & jerk. The education methods used in Weightlifting can also be utilised by Strength & Conditioning coaches as a way of weight training for the wide range of other sports. Most significant reasons behind exploiting various weight training modalities such is made for power development. There are lots of variations on the party’s 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 used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks in addition to their variations) conducted inside the exercise (Garhammer, 1993). It’s traditionally been described as productive way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are other important considerations which require to get addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of your athlete, some of these include movement competency, training age, sport and coaching time with athlete. The purpose of this article by Elite Performance Institute (EPI) is always to give you a biomechanical and physiological discussion why weightlifting exercises are helpful to improve athletic performance and exactly how they will be performed within a exercise program.

Power Defined
Power has been thought as the best mix of speed and strength to make movement (Chu 1996). Specifically, power represents draught beer the athlete to make high degrees of work through a certain distance. The greater power an athlete possesses the better the amount of work performed (Wilson 1992). Power is really a mix of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are lots of physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength contain 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of movement comprises many different interrelated factors (Ackland & Bloomfield 1995). They are; (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 progression of the very center (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Courses UK regarding the type of strength developed from each exercise, session or phase to train inside the program. Therefore, the force & Conditioning coach can effectively plan which kind of power to merely develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is most beneficial utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises inside the weight training programs of athletes in sports besides weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time needed to discover the movements due to the complexity with the lifts. 2) Deficiencies in comprehension of the opportunity bene?ts that may be produced from performing Olympic lifting exercises correctly. 3) Concern on the prospect of injury resulting from practicing these weightlifting movements.
It really is evident there is a plethora of biomechanical advantages of practicing these lifts with limited disadvantages. The biggest risk has been with the perceived danger of practicing these lifts. On the basis of the evidence presented by Brian Hammill with the British Weightlifting Association (BWLA), it is usually stated with con?dence that the risk of harm is as low or lower than most sports providing there is quali?ed supervision given by certi?ed Strength and Conditioning coach who are trained in coaching the weightlifting movements.
