Introduction
Olympic Weightlifting can be a sport where athletes compete for your total weight of 2 lifts: the snatch and also the clean & jerk. The training methods used in Weightlifting are also utilised by Strength & Conditioning coaches as a technique of lifting weights for any number of other sports. One of the greatest causes of exploiting various lifting weights modalities such is for power development. There are many variations on the party’s 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 favorite method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted within the exercise (Garhammer, 1993). It’s traditionally been viewed as a effective way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations that demand to get addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of an athlete, some of these include movement competency, training age, sport and coaching time with athlete. The goal of this article by Elite Performance Institute (EPI) is always to give a biomechanical and physiological discussion why weightlifting work outs are helpful to improve athletic performance and the way they should be performed inside a training course.

Power Defined
Power has been thought as the best combination of speed and strength to produce movement (Chu 1996). Particularly, power represents draught beer the athlete to produce high levels of process certain distance. The greater power an athlete possesses the larger the amount of work performed (Wilson 1992). Power can be a combination of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are many physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include an increase in muscle tissues through hypertrophy, ligament 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) increase in intra-muscular coordination; and (5) increase in inter-muscular coordination.
Speed of movement comprises a number of 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 middle (Strength-Speed and Speed-Strength) from the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Certification UK regarding the sort of strength developed from each exercise, session or phase of coaching within the program. As a result, the force & Conditioning coach can effectively plan what type 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 for the ef?cacy of including Olympic weightlifting exercises within the lifting weights programs of athletes in sports besides weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time required to study the movements due to the complexity from the lifts. 2) Deficiencies in idea of the possibility bene?ts which can be derived from performing Olympic lifting exercises correctly. 3) Concern on the potential for injury as a result of performing these weightlifting movements.
It really is evident you can find a plethora of biomechanical great things about performing these lifts with limited disadvantages. The biggest risk has been from the perceived danger of performing these lifts. On the basis of evidence presented by Brian Hammill from the British Weightlifting Association (BWLA), it could be stated with con?dence how the injury risk will be as low or less than most sports provided that there’s quali?ed supervision furnished by certi?ed Strength and Conditioning coach who have been trained in coaching the weightlifting movements.
