Introduction
Olympic Weightlifting is often a sport where athletes compete for that total weight of two lifts: the snatch and also the clean & jerk. The training methods utilized in Weightlifting may also be utilised by Strength & Conditioning coaches as a method of lifting weights for a number of other sports. One of the first reasons behind exploiting various lifting weights modalities such is for power development. There are many 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 trendy method utilized to increase athletic power is Olympic Weightlifting (ie power cleans, push presses, snatches, jump jerks in addition to their variations) conducted within the exercise (Garhammer, 1993). It has traditionally been viewed as a effective way of producing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are additional important considerations which require to become addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of an athlete, some of these include movement competency, training age, sport and coaching time with athlete. The purpose of this post by Elite Performance Institute (EPI) is always to give you a biomechanical and physiological discussion as to the reasons weightlifting workouts are beneficial to improve athletic performance and just how they ought to be performed inside a training course.

Power Defined
Power continues to be understood to be the perfect mixture of speed and strength to produce movement (Chu 1996). Specifically, power represents the ability of the athlete to produce high levels of function with confirmed distance. The greater power a player possesses the greater the amount of work performed (Wilson 1992). Power is often a mixture of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed of motion)
There are many physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength incorporate more muscle tissues through hypertrophy, ligament density and bone integrity (Tesch 1992a). Neural adaptations (Schmidtbleicher 1992) which can be produced are: (1) increased recruitment of motor units; (2) increased firing rate of motor neurones; (3) synchronised firing of motor neurones; (4) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed of motion comprises a number of interrelated factors (Ackland & Bloomfield 1995). These are generally; (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 center (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 based on the form of strength developed from each exercise, session or phase of education within the program. As a result, the force & Conditioning coach can effectively plan which 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 regarding ef?cacy of including Olympic weightlifting exercises within the lifting weights programs of athletes in sports aside from weightlifting. These concerns generally fall into 3 broad categories: 1) Perceived time required to discover the movements as a result of complexity in the lifts. 2) Deficiencies in idea of the possible bene?ts which can be derived from performing Olympic lifting exercises correctly. 3) Concern on the possibility of injury resulting from these weightlifting movements.
It’s evident there are a plethora of biomechanical important things about these lifts with limited disadvantages. The biggest risk continues to be in the perceived danger of these lifts. On such basis as the data presented by Brian Hammill in the British Weightlifting Association (BWLA), it could be stated with con?dence that this risk of injury is really as low or less than most sports providing there is quali?ed supervision given by certi?ed Strength and Conditioning coach who have been been trained in coaching the weightlifting movements.
