In this article, we critically review the available literature related to Plyometric training and its effects on physical fitness in team sport athletes. The purpose of the study was to investigate the effect of plyometric training on selected physical fitness and skill variables of intercollegiate level male football players. Thirty out of players were randomly selected from Sri Ramakrishna Mission Vidyalaya College of Arts and Science, Coimbatore the selected players were divided into two groups consisting of 15 players. No attempt was made equate the groups. The age of the subjects ranged between 18 to 25 years. The influence of the plyometric exercise was assessed on physical variables. The training load was increased from the maximum working capacity of the subject doing pilot study. The duration of the training period was restricted to six weeks and the number of sessions per week was confined to three. The data obtained from all the groups before and after the experimental period were statistically analyzed by dependent‘t’ test to find out the significant improvement if any, 0.05 level of confidence was fixed to the level of significance between pre and post test means of all groups Keywords: Plyometric, physical conditioning, extensively Introduction Plyometric training is a very popular form of physical conditioning of healthy individuals that has been extensively studied over the last decades. In this article, we critically review the available literature related to Plyometric training and its effects on physical fitness in team sport athletes.I have chosen this topic to elevate the physical exercise of the football players. Football players should have strength in their lower body because of most of the activity and skill execution in football player’s game is emphasize lower body. Their lower body is strengthened throw implementing plyometric exercise as a training program while playing football the skills like kicking, dribbling, dropping, and running are applied more frequently these moment on their lower body have to be strength only then the can play better with sprit for the entire game. We can develop or upgrade their lower body through plyometric exercise such as skipping, jumping, hopping, double leg jump and plyometric box jump. These kind of exercise will help them will play effectively. Plyometric jumping exercisecan build power and speed if done properly. Many athletes and trainers use plyometric jumping exercises to build power and speed and above to improve coordination and agility in sports performance. It’s also recognize that these are high risk exercise and if performed incorrectly or performed without a solid base of training can increases the risk of injuries. These kind of exercises not only felt. The athletes but also enhance the sports performance in the game football. Methods and Procedures The purpose of this study was to find out the effect of plyometric training on selected physical fitness and skill variables of intercollegiate level football players. To achieve the purpose of the study, thirty male football players were randomly selected from Sri Ramakrishna Mission Vidyalaya College of arts and science Coimbatore. Their age ranged from 18 to 25 years. They were divided into two equals groups. The group I was considered as experimental group and group II was considered as control group. The investigator did not made any attempt to equate the group. The control group was not given any treatment and the experimental group was given plyometric training for three days per week. The experimental group was given training for the period of six weeks of plyometric training. Statistical techniques The collected data on speed and kicking ability due to the effect of plyometric training was analyzed by computing mean and standard deviation. In order to find out the study to used‘t’ test was applied at 0.05 level of confidence was fixed to test the level of significance. Results and Discussion The t test was used to analyze the data collected on speed and kicking ability of inter-collegiate football players for applying t’ International Journal of Physiology, Health and Physical Education www.physiologyjournals.com Online ISSN: 2664-7273; Print ISSN: 2664-7273; Impact Factor: RJIF 5.42 Received: 14-01-2020; Accepted: 29-01-2020; Published 13-02-2020 Volume 2; Issue 1; 2020; Page No. 17-19
