- 运动医学 运动医学
- 眼科医生 眼科 眼科
背景情况:
- 接触运动中重复的头部冲击 (RHI) 可能会影响大脑功能,即使没有脑震荡症状.
- 目前的临床测试可能无法检测RHI带来的微妙的神经变化.
- 眼运动控制对神经系统的变化很敏感.
研究的目的:
- 为了研究重复的头部冲击 (RHI) 和眼运动控制在美国第一师足球运动员在一个赛季之间的关联.
- 为了确定一个季节的RHI是否会导致眼动控制的可测量变化.

- 仪器口罩在一个赛季内跟踪头部撞击.
- 参与者完成了眼睛追踪任务,在季前赛,中赛和季后赛中测量了光滑追踪眼睛运动速度.
主要成果:
- 在高剂量或低剂量RHI组中,在赛季内没有观察到光滑追踪眼动速度的显著变化.
- 在季前赛中,高剂量的RHI玩家与对照组相比,表现出较慢的平滑追逐速度.

21.3K
According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Projectile motion becomes evident when a player kicks the ball into the air. The launch angle, or the angle at which the ball is kicked, plays a crucial role in determining the trajectory of the projectile. As the ball soars through the air, influenced solely by gravity, its motion can be dissected into two independent velocity components: the horizontal and the vertical.
Horizontal motion, governed by the initial kick, maintains a constant velocity throughout the flight of the soccer ball.

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...
