Video Analysis

This is a video of me performing a block start. In this video there are some key bio-mechanical principles marked at the full extension phase of the start. This step is crucial in getting a good start. The optimum angle on the body to the ground is around 40 degrees. In this video my body was about 36 from the ground. However, it was a good start because my heel, knee, waist, and shoulders were in line. The knee the drives out of the blocks (right knee)made a 92 degree angle which is close to optimum to have a good "dig". This is a video of me performing a block start. In this video there are some key bio-mechanical principles marked at the full extension phase of the start. This step is crucial in getting a good start. The optimum angle on the body to the ground is around 40 degrees. In this video my body was about 38 from the ground, which is almost perfect. This was also a good start because my heel, knee, waist, and shoulders were in line. The knee the drives out of the blocks (right knee)made a 80 degree angle which is isn't as close to optimum to have a good "dig" phase. This is a long jump analysis of two different jumpers.Using Dartfish the two videos are compared side by side. Two primary angle are measured that have a great impact on the overall performance of the jump. This first angle is of the knee during the full extension of the take off. The second angle is of the in flight landing position. The optimum form for these key positions are: Knee Drive high, and at about 90 degrees. The optimum landing position is having the legs parallel with the pit and the upper body in the most forward position as possible. A timer was put in to compare hang time between jumpers. The longer the hang time the better.
