|a The purpose of this study was to begin to fill the gap of information that exists in biomechanically quantifying the sport of skateboarding. Skateboarding has several million regular participants in the US alone and a relatively high incidence of injury (Kyle et al., 2002). Many of these injuries are the result of un-controlled landings and what can be assumed take-off forces produced to accomplish certain maneuvers. With 13 million people averaged to be skateboarders there is a gap in information related to quantifying this sport. In this current study, focus was geared towards the maximal take-off forces generated by the kickflip maneuver as well as looking at net joint moments produced. Three male skateboarders with less than 2 years of experience and three male skateboarders with more than 2 years experience participated. A multi-component force plate (AMTI 4507) was used. The plate recorded data in the Z axis for vertical force. Ground reaction forces were recorded directly into the computer program through an A/D converter. The ground reaction forces were amplified (SGA6-4) with a gain set at 4000 Hz. The skateboarders were asked to perform a successful kickflip maneuver on the force platform while on their skateboards. Peak forces were computed to compare the two groups of experience levels in the take-off phase only. Lower extremity kinematics were also calculated to provide body orientation in the air at take-off phase. Shared positive contribution (SPC) was also calculated to show the intersegmental coordination of the lower limbs. One-way MANOVAs were used to calculate; range of motion of the hip, knee and ankle; the hip, knee and ankle take-off angles; and the SPC of the hip to knee, and the knee to ankle. The vertical ground reaction force was statistically determined by a univariate ANOVA. Results found no significance difference in the above parameters but trends were discovered. |
