Introduction
Olympic Weightlifting can be a sport in which athletes compete for the total weight of 2 lifts: the snatch and also the clean & jerk. The training methods utilized in Weightlifting will also be utilised by Strength & Conditioning coaches as a way of resistance training for the great deal of other sports. One of the greatest reasons behind exploiting various resistance training modalities such is good for power development. There are lots of 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 trendy method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks and their variations) conducted inside the weight room (Garhammer, 1993). It is traditionally been viewed as a efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are many important considerations which require to get addressed when implementing Olympic lifting exercises to the Strength & Conditioning program associated with an athlete, some include movement competency, training age, sport and coaching time with athlete. The goal of this short article by Elite Performance Institute (EPI) would be to give a biomechanical and physiological discussion as to the reasons weightlifting exercises are helpful to improve athletic performance and how they will be performed in the training course.

Power Defined
Power may be defined as the optimal combination of speed and strength to produce movement (Chu 1996). Particularly, power represents ale the athlete to produce high degrees of work through confirmed distance. The greater power an athlete possesses the larger the amount of work performed (Wilson 1992). Power can be a combination of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are lots of physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength consist of more muscle mass 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) boost in intra-muscular coordination; and (5) boost in inter-muscular coordination.
Speed of movement is made up of various 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 technique series elastic component.
Olympic Weightling exercises facilitate development 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 Courses Ireland according to the type of strength developed from each exercise, session or phase to train inside the program. Consequently, the force & Conditioning coach can effectively plan what sort of power to merely develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is best utilised to elicit these adaptations.
Conclusion
Concern still exists for the ef?cacy of including Olympic weightlifting exercises inside the resistance training programs of athletes in sports aside from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time required to study the movements due to the complexity with the lifts. 2) Too little idea of the possible bene?ts that can be derived from performing Olympic lifting exercises correctly. 3) Concern on the possibility of injury resulting from performing these weightlifting movements.
It’s evident there are a multitude of biomechanical advantages of performing these lifts with limited disadvantages. The biggest risk may be with the perceived danger of performing these lifts. Based on the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it could be stated with con?dence the risk of harm can be as low or under most sports as long as there exists quali?ed supervision supplied by certi?ed Strength and Conditioning coach who had been competed in coaching the weightlifting movements.
