Introduction
Olympic Weightlifting is often a sport by which athletes compete to the total weight of 2 lifts: the snatch and also the clean & jerk. The courses methods utilized in Weightlifting are also utilized by Strength & Conditioning coaches as a means of weight training for a number of other sports. One of the first reasons behind exploiting various weight training modalities such is good for power development. There are numerous variations on the 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 utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted within the training (Garhammer, 1993). It’s traditionally been viewed as a efficient way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require to be addressed when implementing Olympic lifting exercises in the Strength & Conditioning program associated with an 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 work outs are beneficial to improve athletic performance and the way they ought to be performed in the exercise program.

Power Defined
Power has become thought as the perfect mixture of speed and strength to produce movement (Chu 1996). More specifically, power represents ale the athlete to produce high numbers of sort out a certain distance. The greater power a sports athlete possesses the greater the amount of work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are numerous physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength include an increase in muscle tissue 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) surge in intra-muscular coordination; and (5) surge in inter-muscular coordination.
Speed to move is composed of a variety 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 very center (Strength-Speed and Speed-Strength) in the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Courses with regards to the form of strength developed from each exercise, session or phase of education within 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 the most suitable utilised to elicit these adaptations.
Conclusion
Concern still exists regarding ef?cacy of including Olympic weightlifting exercises within the weight training programs of athletes in sports apart from weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time forced to discover the movements as a result of complexity in the lifts. 2) An absence of idea of the opportunity bene?ts that may be based on performing Olympic lifting exercises correctly. 3) Concern in the prospect of injury as a result of doing these weightlifting movements.
It is evident there are a great number of biomechanical benefits of doing these lifts with limited disadvantages. The biggest risk has become in the perceived danger of doing these lifts. On such basis as the data presented by Brian Hammill in the British Weightlifting Association (BWLA), it can be stated with con?dence how the risk of injury is really as low or lower than most sports so long as there is certainly quali?ed supervision given by certi?ed Strength and Conditioning coach who have been trained in coaching the weightlifting movements.
