Introduction
Olympic Weightlifting can be a sport by which athletes compete for your total weight of 2 lifts: the snatch as well as the clean & jerk. The courses methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a means of strength training for a number of other sports. Most significant reasons behind exploiting various strength training modalities such is perfect 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 trendy method used to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks as well as their variations) conducted inside the training (Garhammer, 1993). It is traditionally been described as productive way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are other important considerations which need to be addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of the athlete, some include movement competency, training age, sport and training time with athlete. The objective of this short article by Elite Performance Institute (EPI) is to give you a biomechanical and physiological discussion as to the reasons weightlifting exercises are helpful to improve athletic performance and the way they must be performed within a training curriculum.

Power Defined
Power continues to be defined as the best combination of speed and strength to create movement (Chu 1996). More specifically, power represents the ability of the athlete to create high numbers of function with confirmed distance. Greater power a sports 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 to move)
There are numerous physiological and neural adaptations which comprise the force component (Moritani 1992). Physiological adaptations to strength incorporate more muscle mass through hypertrophy, ligament 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) increase in intra-muscular coordination; and (5) increase in inter-muscular coordination.
Speed to move comprises a variety of interrelated factors (Ackland & Bloomfield 1995). They 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 progression of the very center (Strength-Speed and Speed-Strength) of the force-velocity (FV) curve (see above). The FV curve acts a map to Strength & Conditioning Courses Ireland with regards to the sort of strength developed from each exercise, session or phase to train inside the program. Therefore, the Strength & Conditioning coach can effectively plan what type of power they would like to develop and which training modality (powerlifting, Olympic liftining, plyometrics, etc) is most beneficial utilised to elicit these adaptations.
Conclusion
Concern still exists for the ef?cacy of including Olympic weightlifting exercises inside the strength training programs of athletes in sports besides weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time needed to learn the movements due to the complexity of the lifts. 2) Deficiencies in idea of the possible bene?ts that may be produced from performing Olympic lifting exercises correctly. 3) Concern in the risk of injury resulting from these weightlifting movements.
It really is evident there’s a great number of biomechanical important things about these lifts with limited disadvantages. The biggest risk continues to be of the perceived danger of these lifts. On such basis as evidence presented by Brian Hammill of the British Weightlifting Association (BWLA), it could be stated with con?dence the injury risk is as low or lower than most sports provided that there’s quali?ed supervision given by certi?ed Strength and Conditioning coach who are competed in coaching the weightlifting movements.
