Optimum 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 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...
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 techniques for high and long jumps.
High jumpers run at moderate speeds and set down the foot, from which they take off, well in front of the body. Long jumpers run up much faster and place the foot less far forward, with the leg at a steeper angle. A simple model, which takes into account the mechanical properties of muscle, predicts optimum take-off techniques that agree well with those used by athletes. These predictions are r...
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 ...
