Vertical Acceleration To The Ground Can Be A Greater Component Contributing To Higher Sprinting Performance

In this study we investigated the changes of 3 - dimensional accelerations (Za vertical to the ground, Ya vertical to X and horizontal to the ground, Xa horizontal to the ground and toward the goal) of the sprinting athletes. Subjects of 13 Japanese male high school athletes underwent a single time-...

Description
Summary:In this study we investigated the changes of 3 - dimensional accelerations (Za vertical to the ground, Ya vertical to X and horizontal to the ground, Xa horizontal to the ground and toward the goal) of the sprinting athletes. Subjects of 13 Japanese male high school athletes underwent a single time-trial of 100 m sprint, wearing a triaxial accelerometer on their center of the gravity in the lower abdominal area. All through 100 m distance, 5 sets of split times and speeds were recorded at each 20 m section (the 1st section of 0-20 m as S1, the 2nd 20-40 m S2, the 3rd 40-60 m S3, the 4th 60-80 m S4 and 5th 80-100 m S5). Compared the measured accelerations between the Faster and the Slower, Za of the Faster was statistically greater than that of the Slower at S4 (-1,691.42 + or - 373.76 m/s*2 vs. - 2,498.77 + or - 341.19 m/s*2 p
