The effect of plyometric training on vertical jump height and speed in football

Summary
This study will be looking at how plyometric training affects vertical jump height and speed in football. Football is a sport that acquires exertion of power and this exertion can be through sprinting, jumping or tackling. Training using plyometric training recruits faster twitch muscles fibres exerting forces in order for an athlete to jump higher. An increase in the recruitment of fast twitch muscle fibres causes hypertrophy of the muscles in legs; these are gastrocnemius, hamstring, gluteus Maximus, soleus, Achilles tendon as well as abdominal muscles in the middle region of the body. There have been similar studies that other scientists have looked, …show more content…

Low intensity plyometric training is gentle, produces the same effect being less exhaustive for players and also requires much less recovery time and has no amortization phase in comparison with high intensity which is a vigorous, takes longer and is more exhaustive training regime with very quick amortization phase. (Shankar, R., Rajpal etal 2008). For this study high intensity plyometric training will be used for vertical jump and speed. Shankar, R., Rajpal etal (2008) who looked at the effect of high and low intensity plyometric training on Jump Height and Maximum Voluntary Isometric Contraction in Football Players, found that high intensity plyometric training had significant effect on vertical jump height and maximum voluntary isometric …show more content…

Football requires a great range of strength, power and speed as these factors contribute highly to the performance of football player. During a game of football every 90 seconds a 2 to 4 second sprint occurs. From a 90 minute game sprinting occupies 3% of the overall playing time and accounts for 1-11% of overall playing time. For other players 96% of sprints are no longer than 30m and 50% are more than 10m long. (Kotzamanidis, Christos; Chatzopoulos etal 2010)
Furthermore a football match demands various explosive movements including tackling, frequent kicking and changes of pace and direction. Anaerobic performance and jumping ability are critical aspects to a football player. As football has become more athletic, short term muscle power burst have become increasingly crucial in many high intensity matches. (Kotzamanidis, Christos; Chatzopoulos etal
