Effectiveness of 6 Weeks Plyometric Training on Agility Among University Male Students.

The ability of the neuromuscular and musculoskeletal systems to generate force at a specific velocity, in a particular direction, appears to be critical for many sports that involve sprinting, jumping and throwing. In light of the above, plyometric training can be used to enhance the ability of skeletal muscle to exert maximal force in as short a time as possible. Plyometric training typically includes various unilateral and bilateral jumps, hops and bounds with coaches often prescribing these in a multidirectional fashion to reflect the unpredictable nature of field and court sports. The rationale of this approach is founded on the well-accepted principle that adaptations to vertically (VPT) and horizontally orientated PT will transfer better to athletic tasks that are carried out in the same direction as they are performed. Plyometric consists of a rapid stretching of a muscle (eccentric action) immediately followed by a concentric or shortening action of the same muscle and connective tissue, the stored elastic energy within the muscle is used to produce more force than can be provided by a concentric action alone. Though aerobic capacity is important during a soccer game high-intensity single-bout efforts also play an important role for physical performance. in this sense, aside from endurance activity, female soccer players must also perform numerous explosive action including jumping, kicking, accelerating, decelerating and changing of direction, with most of these preceding goal opportunities in competitive leagues. specifically, the straight sprint (45%) followed by vertical jumps (16%) have shown to be the two most frequent actions in goal situations during professional soccer matches. Studies also suggest that changes in motor performance skills resulting from the performance of combined resistance training and plyometric training are greater than with either type of training alone. Six weeks of combined resistance training and plyometric training would lead to greater improvements in fitness performance in healthy boys than resistance training and static stretching. Plyometric training has been proposed for the development of explosive power performance and specifically for the improvement of vertical jump ability. he main finding of this study was the improvement of either vertical- and horizontal jump performance in basketball players as a consequence of a multipurpose plyometric training intervention.
