Introduction
Olympic Weightlifting is often a sport through which athletes compete for your total weight of 2 lifts: the snatch and the clean & jerk. The training methods utilized in Weightlifting are also utilized by Strength & Conditioning coaches as a way of resistance training to get a wide range of other sports. One of the greatest reasons for exploiting various resistance training modalities such is for power development. There are lots of variations on the party’s 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 trendy method employed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted within the weight room (Garhammer, 1993). It’s traditionally been described as productive way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are other important considerations that demand to get addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of an athlete, many of these include movement competency, training age, sport and coaching time with athlete. The purpose of this short article by Elite Performance Institute (EPI) would be to provide a biomechanical and physiological discussion that explains why weightlifting exercises are useful to improve athletic performance and exactly how they will be performed in the exercise program.

Power Defined
Power continues to be thought as the best blend of speed and strength to create movement (Chu 1996). More specifically, power represents draught beer the athlete to create high amounts of process certain distance. The greater power a sports athlete possesses the better the level of work performed (Wilson 1992). Power is often a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are lots of physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength contain a rise in muscle tissues through hypertrophy, connective tissue density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) that can 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 of motion is made up of a number of 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 technique series elastic component.
Olympic Weightling exercises facilitate progression of the middle (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a guide to Strength & Conditioning Certification Ireland based on the type of strength developed from each exercise, session or phase to train within the program. Consequently, the Strength & Conditioning coach can effectively plan which kind of power to merely develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is most beneficial utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises within the resistance training programs of athletes in sports besides weightlifting. These concerns generally belong to 3 broad categories: 1) Perceived time needed to educate yourself on the movements as a result of complexity with the lifts. 2) A lack of understanding of the possibility bene?ts that can be produced from performing Olympic lifting exercises correctly. 3) Concern over the prospect of injury caused by doing these weightlifting movements.
It is evident there’s a great number of biomechanical great things about doing these lifts with limited disadvantages. The biggest risk continues to be with the perceived danger of doing these lifts. On such basis as the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it may be stated with con?dence that this risk of harm is really as low or under most sports provided that there is certainly quali?ed supervision furnished by certi?ed Strength and Conditioning coach who have been trained in coaching the weightlifting movements.
