Resumen
La dureza de la suela media del zapato de correr afecta la biomecánica de manera diferente a diferentes velocidades. La planta intermedia más blanda reduce el movimiento del tobillo a velocidades más bajas, pero aumenta el movimiento de la cadera y la carga del antepié a velocidades más altas, lo que afecta el riesgo de lesiones.
Área de la Ciencia:
- Biomecánica
- Medicina del deporte
- Hacer funcionar la ciencia
Sus antecedentes:
- La dureza de la plantilla del zapato de correr es crucial para la protección del pie.
- Las investigaciones anteriores sobre la dureza de la suela intermedia y la biomecánica de la carrera carecen de resultados consistentes, a menudo descuidando la velocidad de carrera.
- Comprender la interacción entre las propiedades de la plantilla intermedia y la velocidad de ejecución es vital para la prevención de lesiones.
Objetivo del estudio:
- Investigar el impacto de la dureza de la suela intermedia en los ángulos de las articulaciones de las extremidades inferiores y la carga plantar a diferentes velocidades de carrera.
- Determinar si la dureza de la suela media tiene un efecto variable en la biomecánica de funcionamiento a velocidades variables.
Principales métodos:
- Ocho corredores masculinos participaron en el estudio.
- Los participantes corrieron en una cinta de correr a seis velocidades diferentes, desde la velocidad auto-seleccionada (SSV) hasta el 200% de SSV, tanto en entresuelas blandas como en duras.
- Los ángulos de las articulaciones de las extremidades inferiores y la carga plantar se midieron utilizando tecnología avanzada de captura de movimiento y suela.
Principales resultados:
- Las plantillas más blandas reducen la inversión del tobillo a velocidades más bajas (SSV y 120% SSV).
- A velocidades más altas (180% y 200% SSV), las plantas intermedia más blandas aumentaron la abducción de la cadera y la fuerza de la región metatarsiana, lo que potencialmente redujo la estabilidad y aumentó el riesgo de lesión en el antepié.
- La dureza de la suela media exhibió un efecto no lineal en la carga articular y plantar en relación con la velocidad de marcha.
Conclusiones:
- La dureza de la suela media influye significativamente en la biomecánica del funcionamiento de una manera dependiente de la velocidad.
- La atención al movimiento de la articulación del tobillo a 100-120% de SSV y al movimiento de la cadera/tobillo con carga metatarsiana/arco a 180-200% de SSV es crucial para las estrategias de reducción de lesiones.
- Los hallazgos ofrecen información valiosa para diseñar zapatos para correr y programas de entrenamiento para mitigar las lesiones relacionadas con el correr.

01:10Ankle Joint
1.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:26Impact: Problem Solving
258
In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

01:19Impact Loading
281
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.

01:22Toughness and Hardness of Aggregate
334
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in...

01:21Impact Strength of Concrete
329
Impact strength in concrete is a critical measure that reflects the material's capability to endure the forces applied during pile driving and when supporting machinery foundations that experience impulsive loads. It is also essential when handling precast concrete components to prevent accidental damage. The impact strength is assessed by observing the concrete's resistance to repeated impacts and energy absorption capacity. A key indicator of significant damage to concrete is when it...

01:23Abrasion Resistance of Concrete
201
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.
