Introduction
Olympic Weightlifting is a sport through which athletes compete for that total weight of 2 lifts: the snatch and also the clean & jerk. The courses methods found in Weightlifting can also be employed by Strength & Conditioning coaches as a way of resistance training for any massive amount other sports. Most significant causes of exploiting various resistance training modalities such is made for power development. There are numerous 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 favorite method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted within the exercise (Garhammer, 1993). This has traditionally been described as effective way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations which require to become addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of the athlete, some include movement competency, training age, sport and training time with athlete. The goal of this article by Elite Performance Institute (EPI) would be to give a biomechanical and physiological discussion as to why weightlifting workouts are beneficial to improve athletic performance and the way they must be performed in a exercise program.

Power Defined
Power has been thought as the perfect combination of speed and strength to generate movement (Chu 1996). Specifically, power represents the ability of the athlete to generate high amounts of sort out a given distance. The harder power a player possesses the greater the amount of work performed (Wilson 1992). Power is a combination of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are numerous physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include more muscular 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of motion consists of 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 utilisation of the series elastic component.
Olympic Weightling exercises facilitate growth and development of the guts (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Courses UK based on the type of strength developed from each exercise, session or phase of training within the program. Because of this, the Strength & Conditioning coach can effectively plan what type of power they need to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is better utilised to elicit these adaptations.
Conclusion
Concern still exists regarding ef?cacy of including Olympic weightlifting exercises within the resistance training programs of athletes in sports apart from weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time required to educate yourself on the movements because of the complexity of the lifts. 2) A lack of idea of the potential bene?ts which can be produced from performing Olympic lifting exercises correctly. 3) Concern on the potential for injury caused by these weightlifting movements.
It really is evident you can find a multitude of biomechanical great things about these lifts with limited disadvantages. The biggest risk has been of the perceived danger of these lifts. Judging by evidence presented by Brian Hammill of the British Weightlifting Association (BWLA), it is usually stated with con?dence the risk of injury can be as low or under most sports so long as there is quali?ed supervision furnished by certi?ed Strength and Conditioning coach who had been competent in coaching the weightlifting movements.
