Strength & Conditioning Courses UK
Introduction
Olympic Weightlifting is really a sport through which athletes compete for your total weight of two lifts: the snatch and the clean & jerk. The training methods used in Weightlifting are also employed by Strength & Conditioning coaches as a way of weight training for a wide range of other sports. One of the first reasons behind exploiting various weight training modalities such is good for power development. There are several variations on the party theme of power training. Some 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 and their variations) conducted in the exercise (Garhammer, 1993). It has traditionally been seen as an efficient way of manufacturing general explosive ability (Takano 1992; Stone 1993; Garhammer & Gregor 1992). However, there are more important considerations that demand to be addressed when implementing Olympic lifting exercises into the Strength & Conditioning program of the 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 provide a biomechanical and physiological discussion as to the reasons weightlifting exercises are useful to improve athletic performance and exactly how they ought to be performed in the exercise program.

Power Defined
Power may be defined as the optimal blend of speed and strength to create movement (Chu 1996). Specifically, power represents ale the athlete to create high degrees of function with confirmed distance. Greater power a player possesses the larger the amount of work performed (Wilson 1992). Power is really a blend of strength and speed:
POWER = FORCE (strength) X VELOCITY (speed to move)
There are several physiological and neural adaptations which comprise the strength component (Moritani 1992). Physiological adaptations to strength contain a boost 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) rise in intra-muscular coordination; and (5) rise in inter-muscular coordination.
Speed to move consists of various 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 continuing development of the middle (Strength-Speed and Speed-Strength) with the force-velocity (FV) curve (see above). The FV curve acts a road map to Strength & Conditioning Courses UK according to the form of strength developed from each exercise, session or phase to train in the program. Because of this, 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 better utilised to elicit these adaptations.
Conclusion
Concern still exists as to the ef?cacy of including Olympic weightlifting exercises in the weight training programs of athletes in sports aside from weightlifting. These concerns generally fall under 3 broad categories: 1) Perceived time required to learn the movements due to complexity with the lifts. 2) Too little comprehension of the possible bene?ts that can be derived from performing Olympic lifting exercises correctly. 3) Concern within the potential for injury caused by these weightlifting movements.
It is evident there are a plethora of biomechanical advantages of these lifts with limited disadvantages. The biggest risk may be with the perceived danger of these lifts. On such basis as the data presented by Brian Hammill with the British Weightlifting Association (BWLA), it could be stated with con?dence that the risk of injury will be as low or under most sports provided that there’s quali?ed supervision provided by certi?ed Strength and Conditioning coach who are been trained in coaching the weightlifting movements.
