Introduction
Olympic Weightlifting is a sport through which athletes compete to the total weight of 2 lifts: the snatch and also the clean & jerk. Working out methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a technique of resistance training to get a great deal of other sports. One of the greatest causes of exploiting various resistance training modalities such is for power development. There are lots of variations on the 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 popular method accustomed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted within the exercise (Garhammer, 1993). This has traditionally been seen as productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations that demand being addressed when implementing Olympic lifting exercises in the Strength & Conditioning program of an athlete, some include movement competency, training age, sport and coaching time with athlete. The objective of this short article by Elite Performance Institute (EPI) would be to give you a biomechanical and physiological discussion as to the reasons weightlifting workouts are helpful to improve athletic performance and the way they should be performed in the training program.

Power Defined
Power continues to be thought as the optimal blend of speed and strength to generate movement (Chu 1996). Particularly, power represents draught beer the athlete to generate high amounts of work through confirmed distance. The more power a player possesses the larger the level of work performed (Wilson 1992). Power is a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are lots of physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength include a rise in muscular tissues through hypertrophy, connective tissue density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that could 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 made up of a number of interrelated factors (Ackland & Bloomfield 1995). They’re; (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 continuing development of the very center (Strength-Speed and Speed-Strength) from the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Certification according to the type of strength developed from each exercise, session or phase of training within the program. Consequently, 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 the most suitable utilised to elicit these adaptations.
Conclusion
Concern still exists regarding the ef?cacy of including Olympic weightlifting exercises within the resistance training programs of athletes in sports aside from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time forced to study the movements due to complexity from the lifts. 2) Too little understanding of the opportunity bene?ts that could be produced by performing Olympic lifting exercises correctly. 3) Concern in the risk of injury due to performing these weightlifting movements.
It can be evident there’s a great number of biomechanical great things about performing these lifts with limited disadvantages. The biggest risk continues to be from the perceived danger of performing these lifts. On the basis of the evidence presented by Brian Hammill from the British Weightlifting Association (BWLA), it is usually stated with con?dence that the risk of injury will be as low or below most sports so long as there’s quali?ed supervision given by certi?ed Strength and Conditioning coach who have been competent in coaching the weightlifting movements.
