Introduction
Olympic Weightlifting is a sport where athletes compete for your total weight of 2 lifts: the snatch as well as the clean & jerk. The courses methods utilized in Weightlifting can also be utilised by Strength & Conditioning coaches as a means of resistance training for a wide range of other sports. One of the greatest causes of exploiting various resistance training modalities such is good for power development. There are numerous 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 well known method accustomed to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks along with their variations) conducted from the exercise (Garhammer, 1993). It is traditionally been seen as efficient of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations which require to get addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of your athlete, some include movement competency, training age, sport and coaching time with athlete. The intention of this article by Elite Performance Institute (EPI) is to give a biomechanical and physiological discussion as to the reasons weightlifting exercises are beneficial to improve athletic performance and just how they will be performed in the training curriculum.

Power Defined
Power continues to be understood to be the optimal blend of speed and strength to make movement (Chu 1996). Particularly, power represents ale the athlete to make high numbers of function with confirmed distance. The greater power an athlete possesses the larger the a higher level work performed (Wilson 1992). Power is a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of movement)
There are numerous physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength include a rise in muscle tissues 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) boost in intra-muscular coordination; and (5) boost in inter-muscular coordination.
Speed of movement consists 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 utilisation of the series elastic component.
Olympic Weightling exercises facilitate continuing development of the guts (Strength-Speed and Speed-Strength) in the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Courses London regarding the type of strength developed from each exercise, session or phase of education from 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 best utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises from the resistance training programs of athletes in sports other than weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time needed to learn the movements as a result of complexity in the lifts. 2) Deficiencies in comprehension of the potential bene?ts that may be produced from performing Olympic lifting exercises correctly. 3) Concern over the potential for injury as a result of performing these weightlifting movements.
It is evident there is a plethora of biomechanical advantages of performing these lifts with limited disadvantages. The biggest risk continues to be in the perceived danger of performing these lifts. On the basis of evidence presented by Brian Hammill in the British Weightlifting Association (BWLA), it is usually stated with con?dence that this risk of harm can be as low or under most sports providing there is quali?ed supervision given by certi?ed Strength and Conditioning coach who’ve been competed in coaching the weightlifting movements.
