This book was released on 1986 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six male college long jumpers volunteered as subjects to determine the kinematic differences between depth jumps from 0.75 m and 1.10 m, and long jump take-off. The variables examined were approach and take-off vertical, horizontal and resultant velocities with contact time and angles of take-off. Subjects undertook six depth jump practice sessions, over a four week period prior to filming. Film speed was 200 frames per second. One trial was filmed of each subject for each condition. Film was analysed on a digitizer interfaced with a microcomputer. Analysis of variance revealed no significant differences among all three conditions for take-off vertical velocities and contact time (p

This book was released on 1999 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine how landing surfaces used in a depth jumping (DJ) plyometric exercise affected kinematic and kinetic variables. Sixteen male and female college students, who were involved in recreational activities, performed 5 DJ onto a force platform alone (hard landing surface) and a 2.35cm thick mat placed onto the force platform (soft landing surface). The maximum angular position and angular velocity measurements were recorded and analyzed for the trunk segment and knee joint at the greatest point of knee flexion during landing using a video camera and an Ariel Performance Analysis System (APAS). Contact and flight times were established using data collected by a Bertec force platform. The vertical ground reaction forces and the rate at which these forces were generated were collected and analyzed between surface conditions. An alpha level of 0.05 was used in all statistical tests. A t-test was used for all statistical analyses. Results indicated no significant differences in the maximum angular positions of knee and trunk segments at landing (p = 0.424 and 0.266, respectively). Angular velocities of the knee and trunk segment at landing were not significant (p = 0.153 and 0.243, respectively). The contact and flight times were found to be nonsignificant (p = 0.263 and 0.397, respectively). The time to peak vertical ground reaction force was also found to be nonsignificant (p = 0.224). From the results, it can be concluded that a soft landing surface, 2.35cm thick, would be as effective at eliciting the desired traits (decreased joint flexion, decreased contact time, and increased flight time) of the DJ exercise as a hard landing surface.

Book excerpt: The performance of individuals jumping tabletop features in terrain parks has not been widely studied. A field study was conducted to measure the takeoff speed and horizontal distance achieved by jumpers at two tabletop style jump features: A smaller jump at Snow Summit, CA and a larger jump at Mammoth Mountain, CA, USA. Analyses were also conducted to determine the effects of equipment type (skis versus snowboard) on jumper kinematics. Before each data collection session, the physical dimensions of the jump were measured and recorded. For consecutive jumpers, the speed parallel to the ramp was measured at the end of the takeoff by using a laser speed trap accurate to 0.11 m/s. The landing zone was marked at 3.0 m intervals with colored dye, beginning just past the flat deck portion of the jump. A high-definition video camera was used to record the landing of each jumper, and the landing point of the projected center of mass was determined by using photogrammetry, accurate to within 5 cm. The actual landing distances measured in the field were compared to predicted landing distances by using ordinary ballistic equations. A total of 280 jumps was observed on the two features: 105 on skis and 175 on snowboards. The correlation coefficients between the square of the takeoff speed and the landing distance for the smaller and larger jumps were 0.75 (R2=0.56) and 0.41 (R2=0.16), respectively. The measured landing distances differed significantly from those predicted by models using the ballistic equations of motion. The average landing distance beyond the knuckle was 2.4 m on the smaller jump and 2.1 m on the larger jump. For both features, skier and snowboarder jumpers did not differ in average landing distance.
