3D kinematic analysis of croatian women high jump record – 208 cm

Croatian record holder for the women’s high jump has been dominant female high jumper in the world for the past several years and she has repeatedly tried to break the world record (2, 09m). The aim of this study was to determine kinematic parameters of the her high jump record which is second best jump in the history of women's high jump (2, 08m). Acquisition of the video recordings necessary for the kinematic analysis was made during IAAF Grand Prix meeting in Zagreb, 31st August 2009. Three digital Sony HDR-HC9E cameras, each with frequency of 50Hz were used. The cameras were recording last two strides of approach, take- off and flight phase. Data analysis were performed according APAS (Ariel Performance Analyses System) protocol standards. Data for the parameters most frequently used in high jump technique studies were calculated. Lengths of the strides (penultimate and last) were 233, 99 and 208, 58cm. Toe to bar distance was 84, 00cm. Take off contact time was 0, 160sec. Horizontal center of mass (CM) velocities: third last stride (6, 89m/s), penultimate stride (7, 06m/s), touchdown (6, 47m/s) and take off (4, 30m/s). Vertical CM velocity at take off was 3, 63m/s. CM heights at: touchdown (99, 73cm), amortization (106, 51cm), take off (130, 05cm), maximum CM height (205, 54cm) and CM height relative to the bar height (-2, 46cm). Knee angle of amortization and angle of take off were 143, 31° and 40, 17°.
