Introduction
Olympic Weightlifting is really a sport in which athletes compete for that total weight of two lifts: the snatch along with the clean & jerk. The education methods found in Weightlifting will also be used by Strength & Conditioning coaches as a technique of lifting weights to get a massive amount other sports. One of the primary causes of exploiting various lifting weights modalities such is good for power development. There are numerous 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 popular method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted in the exercise (Garhammer, 1993). It is traditionally been seen as efficient way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations that demand to get addressed when implementing Olympic lifting exercises in to the Strength & Conditioning program of the athlete, a few of these include movement competency, training age, sport and training time with athlete. The intention of this short article by Elite Performance Institute (EPI) would be to supply a biomechanical and physiological discussion that explains why weightlifting workouts are helpful to improve athletic performance and just how they ought to be performed in a training course.

Power Defined
Power has been looked as the perfect mixture of speed and strength to create movement (Chu 1996). Specifically, power represents draught beer the athlete to create high numbers of process a certain distance. The greater power an athlete possesses the higher the amount of work performed (Wilson 1992). Power is really a mixture 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 an increase in muscle tissues 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of motion consists of various 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 growth and development of the middle (Strength-Speed and Speed-Strength) from the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Courses based on the kind of strength developed from each exercise, session or phase of education in the program. Therefore, the force & Conditioning coach can effectively plan which power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is the most suitable utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises in the lifting weights programs of athletes in sports aside from weightlifting. These concerns generally get into 3 broad categories: 1) Perceived time needed to learn the movements as a result of complexity from the lifts. 2) A lack of comprehension of the potential bene?ts that may be produced by performing Olympic lifting exercises correctly. 3) Concern within the possibility of injury due to these weightlifting movements.
It’s evident there is a great number of biomechanical advantages of these lifts with limited disadvantages. The biggest risk has been from the perceived danger of these lifts. On the basis of the data presented by Brian Hammill from the British Weightlifting Association (BWLA), it can be stated with con?dence that this injury risk will be as low or less than most sports so long as there’s quali?ed supervision furnished by certi?ed Strength and Conditioning coach who are been trained in coaching the weightlifting movements.
