Approach run is the preparatory phase for many sports skills. There are three aspects to the approach run, a combination of speed any rhythm, correct postural adjustment during the run, accuracy. Running is involved in approach run of Long jumper, approach run of sprinting and many such other preparatory phases of activities. It is interesting to analyze the basic characteristic of running in these cases and find out the differences between the activities, if any. The purpose of this study was stated below-a) to analyze the Kinematic characteristics of running for Long jumper. b) To find out the Kinematic characteristics of running for sprinter c) To understand the difference in Kinematic characteristics of running between Long jumper and sprinter. A total of Eight (8) male subjects were selected for this study. Out of them four were from Long jumper, four were from sprinter. The subjects were of state level participation. The subjects were from different socioeconomic conditions but they all were college and university students. The data were collected in two phases. In the first phase the running action of the subjects were recorded by a making camera operate of a frequency at 24 frames per second. In the second phase the recorded movement was displayed in computer using a appropriate software [Silicon coach Lite live] the recorded movement was displayed in freeze frame condition. The selected parameters were measured from this picture. Selected kinematic parameters of the subjects were the criterion measure for the present study. Selected kinematic characteristics of running were: This included-The Velocity of the Body, Stride Length, Stride Frequency, Arm Velocity, Elbow Angle, Knee Angle, Body Lean. On the basis of results obtained out of statistical analysis of data and within the limitation of study following conclusions were drawn. There is a significant difference between Long jumper group and sprinter in Knee angle. There is no difference between Long jumper and sprinter in Loco motor velocity of the Body, in Stride Length, in Stride Frequency, in Arm Velocity, in Elbow angle, in Body Lean.
