Leg stiffness during phases of countermovement and take-off in vertical jump.
With respect to cyclic movements such as human gait, running or hopping, leg stiffness is a little variable parameter. The aim of this study was to investigate changes in leg stiffness during the phase of countermovement and take-off when performing a single maximum counter-movement jump. Kistler force plates and a BTS SMART system for comprehensive motion analysis were employed in the study. T...
متن کاملThe relationship between selected biomechanical and technical factors and success criteria in long jump take-off performed by elite athletes
Take-off is the critical phase of the long jump event. The aim of this study was to explore the relationships between different variables and success in take-off. 37 trials performed by 8 long jumper, participants in fourth indoor Asian senior athletics championships held in Tehran, with personal best average of 7.68±0.28 meter were recorded at 300 Hz. Five speed-related, five technical and ...
متن کاملOptimum take-off techniques and muscle design for long jump.
A two-segment model based on Alexander (1990; Phil. Trans. R. Soc. Lond. B 329, 3-10) was used to investigate the action of knee extensor muscles during long jumps. A more realistic representation of the muscle and tendon properties than implemented previously was necessary to demonstrate the advantages of eccentric force enhancement and non-linear tendon properties. During the take-off phase o...
متن کاملOptimum take-off angle in the standing long jump.
The aim of this study was to identify and explain the optimum projection angle that maximises the distance achieved in a standing long jump. Five physically active males performed maximum-effort jumps over a wide range of take-off angles, and the jumps were recorded and analysed using a 2-D video analysis procedure. The total jump distance achieved was considered as the sum of three component d...
متن کاملOptimum take-off angle in the long jump.
In this study, we found that the optimum take-off angle for a long jumper may be predicted by combining the equation for the range of a projectile in free flight with the measured relations between take-off speed, take-off height and take-off angle for the athlete. The prediction method was evaluated using video measurements of three experienced male long jumpers who performed maximum-effort ju...
